Description

[0001] The present invention relates to a load-bearing device for receiving and positioning loads, in particular building elements, for building construction and / or for building renovation and with at least one base frame by means of which the load-bearing device can be suspended from a support means, in particular a crane.

[0002] Furthermore, a method for positioning loads, in particular building elements, for building construction and / or building renovation is proposed, in which the load is picked up and positioned by means of a load-carrying device.

[0003] From DE 1 198 977 B a device for picking up loads is known.

[0004] The object of the present invention is therefore to provide a flexible and universally usable load-bearing device with which building construction and / or building renovation can be carried out quickly.

[0005] The problem is solved by a load-carrying device and a method having the features of the independent patent claims.

[0006] A load-bearing device is proposed for supporting and positioning loads during building construction and / or building renovation. The load-bearing device can be used, in particular, to support building elements during building construction or building renovation and to position them correctly. The building elements can also be flat building elements, such as wall elements, panels, or insulation elements. During building renovation, the insulation elements can be arranged on the exterior sides of existing building walls.

[0007] The load-handling device comprises at least one base frame, by means of which the load-handling device can be attached to a support device. The base frame can be attached to a crane or mobile crane in order to position the load attached to the base frame at a construction site.

[0008] Furthermore, the load-handling device comprises at least one attachment device by means of which the load can be suspended from the base frame. Furthermore, the load-handling device has at least one lifting actuator by means of which the at least one attachment device can be moved relative to the base frame in order to raise or lower the load relative to the base frame. The load can be positioned vertically by means of the at least one lifting actuator, for example in order to attach a wall element for subsequent insulation to an existing building wall. The at least one lifting actuator can be controlled in order to reach the intended position of the building element.

[0009] Additionally or alternatively, in particular to the at least one lifting means and the at least one lifting actuator, the load-handling device can comprise at least one holding device for the load, wherein the holding device is movably arranged on the base frame by means of at least one pivot joint, and wherein the load-handling device has a pivot actuator with the aid of which the load can be pivoted relative to the base frame. As a result, the holding device with the load arranged thereon can be tilted, pivoted and / or inclined in order to be able to position the load even in difficult-to-access locations during building construction and / or building renovation. For example, after picking up the load, it can be tilted in order to, for example, drive under a roof overhang. The load can then be pivoted back into the intended orientation, for example a vertical or upright orientation.

[0010] By lifting and lowering the load by means of at least one lifting actuator and / or pivoting by means of the pivoting actuator, the load handling device can be used flexibly and universally for various work steps in building construction and / or building renovation.

[0011] An improvement results if the load-handling device comprises at least one guide device by means of which the at least one lifting device is movably guided. With the aid of the guide device, the at least one lifting device can be guided, for example, along the base frame. This also allows the at least one lifting device to be guided in such a way that it does not come into contact with other, particularly moving, components.

[0012] It is advantageous if the guide device comprises at least one deflection unit, in particular a deflection pulley. This allows the at least one lifting device to be guided without wear and without resistance.

[0013] It is advantageous if the lifting device includes a rope sling and / or a chain sling. Such lifting devices are inexpensive and widely available.

[0014] An improvement results if the base frame comprises at least one pivot bearing on which the holding device for holding the load is arranged or can be arranged. The holding device can also be arranged or detachably mounted on the base frame by means of the at least one pivot bearing. The pivot joint can be formed by means of the pivot bearing on the base frame.

[0015] One advantage results when the holding device comprises a longitudinal beam and at least one adapter unit for holding the load, wherein the longitudinal beam is arranged on the base frame by means of the at least one swivel joint and wherein the adapter unit is arranged on the longitudinal beam. The load can be arranged on the adapter unit. It is further advantageous if the adapter unit is or can be arranged detachably on the longitudinal beam. This allows the load to be arranged first on the adapter unit and then the adapter unit with the load to be arranged on the longitudinal beam. Alternatively, the adapter unit can also be removed if it is not required.

[0016] Furthermore, it is advantageous if the base frame is frame-shaped. Additionally or alternatively, it is advantageous if the base frame comprises at least one longitudinal member, at least one cross member and / or at least one vertical member. Additionally or alternatively, it is advantageous if the base frame is L-shaped or C-shaped in a side view, wherein the L-shape and / or the C-shape is formed by at least one cross member and at least one vertical member. This allows the base frame to have the necessary stability while being lightweight. Furthermore, the C-shape and / or L-shape allows the base frame to encompass projections, such as a roof overhang, for example, so that the load can be positioned closer to the building.

[0017] Furthermore, it is advantageous if the at least one pivot bearing and / or the longitudinal beam is arranged at a free end and / or in the region of the free end of the at least one cross member.

[0018] An advantage results if the at least one guide device is designed such that the attachment means is guided over the free end of the at least one cross member and / or over the longitudinal beam. This allows the load to be suspended in the area of ​​the free end of the cross member and / or in the area of ​​the longitudinal beam.

[0019] It is advantageous if the vertical, longitudinal, and / or cross members are profiled and / or tubular, at least in sections. This provides the base frame with high stability and low weight. It is also advantageous if the vertical, longitudinal, and / or cross members are made of metal, which provides high strength and allows the base frame to be welded together from the corresponding members.

[0020] Additionally or alternatively, it is advantageous if the vertical, longitudinal, and / or transverse beams have through-openings, so that the at least one attachment means is guided by the at least one guide device, at least in sections, within the at least one vertical beam, within the at least one longitudinal beam, and / or within the at least one transverse beam. This ensures that the at least one attachment means is guided in a protected manner.

[0021] It is also advantageous if the holding device, in particular the longitudinal beam, is detachably mounted on the base frame and / or if the adapter unit is detachably mounted on the longitudinal beam. Consequently, the holding device, the longitudinal beam, and / or the adapter unit can be removed from the base frame when not in use.

[0022] It is advantageous if the at least one pivot actuator is arranged between the base frame and the holding device, in particular the longitudinal beam and / or the adapter unit. This allows the pivot actuator to pivot the holding device, in particular the longitudinal beam and / or the adapter unit, relative to the base frame.

[0023] It is advantageous if the at least one swivel actuator is articulated to the base frame and / or the holding device. This allows the swivel actuator to also rotate when the holding device, in particular the longitudinal beam and / or the adapter unit, is swiveled.

[0024] It is advantageous if the holding device, in particular the longitudinal beam, comprises at least one lever and if the at least one pivot actuator is arranged between the at least one lever and the base frame, in particular the vertical support. The lever allows a higher torque to be transmitted to the holding device.

[0025] It is advantageous if the at least one lever includes a passage through which the lifting device can be guided and / or guided. This allows the lifting device to be guided over the longitudinal beam and through the lever.

[0026] It is advantageous if the holding device, in particular the adapter unit, comprises at least one fastening element by means of which the load can be releasably fastened to the holding device, in particular to the adapter unit.

[0027] It is advantageous if at least one fastening element is a clamp and / or a screw plate.

[0028] It is advantageous if the adapter unit is arranged on the longitudinal beam by means of a connecting unit, wherein the connecting unit is preferably detachable.

[0029] It is beneficial if the adapter unit comprises a beam. Additionally or alternatively, it is advantageous if the at least one fastening element and / or the connecting unit can be moved and / or fixed along the adapter unit, in particular along the beam. This allows the height of the at least one fastening element and / or the connecting unit to be adjusted. This allows different sizes of load to be arranged on the adapter unit or the adapter unit can be adapted to the size of the load. For example, the adapter unit, in particular the beam, can have fixing openings so that the at least one fastening element and / or the connecting unit can be fixed using bolts, for example. For this purpose, the bolts are pushed through the at least one fastening element and / or the connecting unit and the adapter unit, in particular the beam.

[0030] Furthermore, it is advantageous if a positive and / or non-positive connection can be formed by means of the connecting unit, wherein the connecting unit is preferably clamped and / or can be clamped onto the longitudinal beam.

[0031] Furthermore, it is advantageous if the load-handling device comprises at least one supply unit, by means of which the at least one swivel actuator and / or the at least one lifting actuator can be operated. The at least one supply unit can be arranged, for example, on a top side or on a side of the base frame opposite the load when the load is suspended.

[0032] It is advantageous if the base frame includes two pivot bearings. This allows the holding device mounted on the base frame to pivot about a pivot axis, which can be formed by the two pivot bearings.

[0033] It is advantageous if the holding device is mounted on the base frame using two swivel joints. This allows the swivel axis to be defined.

[0034] It is advantageous if the load handling device includes two swivel actuators and / or two lifting actuators. This allows even heavy loads to be lifted, lowered, and / or swiveled.

[0035] It is beneficial if the load-handling device has attachment points to which it can be attached to the load-bearing device. The load-bearing device can be, for example, a crane or a mobile crane. The attachment points can be, for example, eyelets or screw points for attaching a chain or rope to the load-handling device.

[0036] It is advantageous if a pulley block is assigned to at least one lifting actuator. Furthermore, each lifting actuator can be assigned a pulley block. This allows the stroke length of the lifting actuator to be increased, especially if it is a hydraulic unit.

[0037] Furthermore, it is advantageous if the at least one lifting actuator and the pulley block are arranged in the vertical, longitudinal, and / or cross beam. These can be tubular and / or profile-shaped. This saves space.

[0038] Furthermore, a method for positioning loads, in particular building elements, for building construction and / or building renovation is proposed.

[0039] During the process, the load is picked up and positioned using a load-handling device.

[0040] In this case, the load-handling device has at least one feature of the preceding and / or subsequent description. In particular, the load-handling device has at least one feature of the preceding and / or subsequent description in order to carry out the method explained in the preceding and / or subsequent description.

[0041] The load is suspended or is suspended from the base frame by means of at least one lifting device.

[0042] Furthermore, the load is raised or lowered relative to the base frame by means of at least one lifting actuator in order to position the load.

[0043] Additionally or alternatively, the load is pivoted relative to the base frame by means of the at least one holding device in order to position the load.

[0044] It is advantageous if the holding device with the load attached can be pivoted toward a horizontal or inclined orientation to position the load. This allows the load to be oriented in such a way that it can, for example, pass under a roof overhang.

[0045] It is advantageous if, after passing under a projection, especially a roof overhang, the load is pivoted from a horizontal or inclined orientation to a vertical orientation. This allows the load to be positioned against the building wall, for example, as a panel, wall element, and / or insulation element for exterior walls.

[0046] Further advantages of the invention are described in the following exemplary embodiments. They show: Figure 1 a perspective view of a load-handling device with attached load with lifting gear and lifting actuators, Figure 2a perspective view of a load-handling device with attached load with lifting gear and lifting actuators, Figure 3 a perspective view of a load-carrying device with lifting gear and a holding device, Figure 4 a side view of an adapter unit of the holding device, Figure 5 a side view of a load-carrying device with a holding device, Figure 6 a side view of a load handling device with attached load as well as slings and lifting actuators when positioning the load on a building, Figure 7 a side view of a load handling device with a suspended load when positioning the load on a building, Figure 8 a rear view of the load-bearing device and Figure 9 a view of the lifting actuator with a pulley.

[0047] Figure 1shows a load-carrying device 1 for receiving and positioning loads 2 for building construction and / or building renovation. The load 2 can be, for example, a building element and preferably also a wall element, a panel, and / or an insulating element for insulating a wall.

[0048] The load-carrying device 1 comprises a base frame 3, by means of which the load-carrying device 1 can be attached to a support means 13. Examples of a support means 13 with the load-carrying device 1 attached thereto are, for example, a crane, as shown in Figure 6 shown, or a mobile crane, as shown in Figure 7 is shown.

[0049] In the present exemplary embodiment, the load-handling device 1 comprises at least one attachment means 4, 5, by means of which the load 2 can be suspended from the base frame 3. A first and a second attachment means 4, 5 are shown here, by means of which the load 2 is suspended. The at least one attachment means 4, 5 can be designed, for example, as a sling cable and / or as a chain sling. The load 2 can, for example, be connected to the attachment means 4, 5 by means of hooks and / or eyes, as can be seen here.

[0050] Furthermore, the load-bearing device of the Figure 1The embodiment shown has at least one lifting actuator 6, 7, by means of which the at least one lifting means 4, 5 can be moved relative to the base frame 3 so that the load 2 can be lifted or lowered. Here, a first and a second lifting actuator 6, 7 are also shown. Furthermore, it is advantageous if, as shown here, a lifting actuator 6, 7 is assigned to each lifting means 4, 5. As a result, the lifting means 4, 5 can be moved independently of one another relative to the base frame 3, thus making it possible for the load 2 to be lifted or lowered at an angle.

[0051] The at least one lifting actuator 6, 7 can, for example, be an electric motor and / or a hydraulic motor that can move the at least one lifting means 4, 5. If the at least one lifting means 4, 5 is designed, for example, as a sling cable and / or a chain suspension, as shown here, the at least one lifting actuator 6, 7 can, for example, wind up or unwind the sling cable and / or the chain suspension in order to lift or lower the load 2.

[0052] In this exemplary embodiment, the load-handling device 1 further comprises a guide device 8 for movably guiding the at least one lifting means 4, 5. With the aid of the guide device 8, the at least one lifting means 4, 5 can be guided, for example, along the base frame 3. Furthermore, the at least one lifting means 4, 5 is guided from the load 2 to the at least one lifting actuator 6, 7 by means of the at least one guide device 8. In this case, the at least one lifting means 4, 5 can be deflected. Guidance by the guide device 8 has the advantage that the at least one lifting means 4, 5 does not cause interference and can be guided in such a way that it does not come into contact with other movable components.

[0053] According to the present exemplary embodiment, the guide device 8 comprises at least one deflection unit 9-12, by means of which the at least one attachment means 4, 5 can be deflected. As can be seen here, the load-handling device 1 comprises four deflection units 9-12, wherein the first and second deflection units 9, 10 are assigned to the first attachment means 4 and the third and fourth deflection units 11, 12 are assigned to the second attachment means 5. This makes it possible, as can be seen here, for the first attachment means 4 and the second attachment means 5 to be deflected twice.

[0054] Since the first and second lifting means 4, 5 in this example are designed as a rope or as a chain, at least some or all of the deflection units 9 - 12 are designed as deflection pulleys, so that the at least one lifting means 4, 5 can roll over them when it is moved by the at least one lifting actuator 6, 7.

[0055] Furthermore, the base frame 3 in this embodiment is frame-shaped. This allows for a sufficiently high stability of the base frame 3 while maintaining a low weight.

[0056] The base frame 3 comprises at least one longitudinal beam 14, 15 extending in a longitudinal direction 22 of the load-handling device 1. Additionally or alternatively, the base frame 3 comprises at least one vertical beam 16, 17 extending in a vertical direction 23 of the load-handling device 1. Additionally or alternatively, the base frame 3 comprises at least one cross beam 18-21 extending in a transverse direction 24 of the load-handling device 1.

[0057] In this exemplary embodiment, the at least one lifting actuator 6, 7 is arranged on the second and / or third cross member 19, 20 and / or on the second longitudinal member 15. The lifting actuators 6, 7 are thus arranged on a side of the base frame 3 facing away from the load 2. The load 2 thus hangs downwards on the base frame 3, and the at least one lifting actuator 6, 7 is arranged on top of the base frame 3. Top and bottom here refer to the vertical direction 23.

[0058] In this exemplary embodiment, the base frame 3 comprises two longitudinal beams 14, 15 and two vertical beams 16, 17, which are connected to one another to form a frame, in particular a two-dimensional frame and / or a rectangular frame. In at least one corner and / or in at least one region of at least one corner of this frame, which is formed from the two longitudinal beams 14, 15 and the two vertical beams 16, 17, the at least one cross beam 18-21 is arranged and / or connected to the longitudinal beam 14, 15 and / or the vertical beam 16, 17. According to the exemplary embodiment shown here, a cross beam 18-21 is arranged in each corner and / or in the region of each corner of the frame. The longitudinal beams 14, 15, the vertical beams 16, 17, and the cross beams 18-21 can, as can be seen here, be oriented in pairs perpendicularly and / or at right angles to one another.

[0059] When viewed in the longitudinal direction 22, the base frame 3 has a C-shape, with the first and second cross members 18, 19 and the first vertical member 16 forming the "C." The third and fourth cross members 20, 21 and the second vertical member 17 are congruent.

[0060] Alternatively, the base frame 3 can also be L-shaped in a lateral view, for example, again in the direction of the longitudinal direction 22. In this case, the first cross member 18 and the vertical member 16 form the "L." The second cross member 19 (as well as the rear third cross member 20) are then removed or not present.

[0061] The at least one longitudinal member 14, 15, the at least one vertical member 16, 17, and / or the at least one cross member 18-21 can, for example, be profiles and / or rectangular profiles, preferably made of metal. These are highly stable and can be easily processed. For example, the at least one longitudinal member 14, 15, the at least one vertical member 16, 17, and / or the at least one cross member 18-21 can be welded and / or screwed together.

[0062] Furthermore, the base frame 3 according to the embodiment shown here can have at least one pivot bearing 25, 26. With the help of the at least one pivot bearing 25, 26, a holding device 28 can be arranged rotatably and / or pivotably on the base frame 3. The holding device 28 is Figure 3 described in more detail. Two pivot bearings 25, 26 are shown here.

[0063] Furthermore, the at least one pivot bearing 25, 26 can be arranged on and / or in a cross member 18-21. As can be seen here, the at least one pivot bearing 25, 26 is arranged at a free end 27 of the at least one cross member 18-21. Since two pivot bearings 25, 26 are shown here, the first pivot bearing 25 is arranged at the free end 27 of the first cross member 18 and the second pivot bearing 26 is arranged at the free end 27 of the fourth cross member 21. The second and third cross members 19, 20 also each have a free end 27, which, however, is not provided with a reference symbol here for the sake of clarity.

[0064] Features that have already been described in at least one preceding figure cannot be explained again for the sake of simplicity. Furthermore, features can also be described in this or in at least one of the subsequent figures. Furthermore, for the sake of simplicity, the same reference symbols are used for the sake of simplicity. Furthermore, for the sake of clarity, not all features can be shown and / or provided with a reference symbol in the following figures. However, features shown in one or more of the preceding figures can also be present in this or in one or more of the subsequent figures. Furthermore, for the sake of clarity, features can also be shown and / or provided with a reference symbol in this or in one or more of the subsequent figures.Nevertheless, features which are only shown in one or more of the subsequent figures may already be present in this or a previous figure.

[0065] Figure 2 shows a perspective view of the load-carrying device 1 with attached load 2 with attachment means 4, 5 and with lifting actuators 6, 7. In this embodiment, the at least one lifting actuator 6, 7 or the two lifting actuators 6, 7 are arranged on the first and / or fourth cross member 18, 21 and / or the first longitudinal member 14. As a result, the at least one lifting actuator 6, 7 is, in comparison to the arrangement of the at least one lifting actuator 6, 7 of the Figure 1 closer to the load 2. This allows the guide device 8 to be designed more simply. As can be seen here, the guide device 8 comprises two deflection units 10, 12.

[0066] In the Figure 3a load-carrying device 1 is shown, which, in particular in addition to or as an alternative to the at least one attachment means 4, 5 and the at least one lifting actuator 6, 7, comprises a holding device 28 for receiving and positioning the load 2. The holding device 28 is described in more detail in this Figure 3 and in the further Figures 4 and 5 described. In the Figure 5 the load 2 is held by the holding device 28.

[0067] Furthermore, the holding device 28 is movably mounted on the base frame 3 by means of at least one pivot joint 29, 30. Furthermore, the load-handling device 1 comprises at least one pivot actuator 31, 32, by means of which the load 2 can be pivoted relative to the base frame 3. With the aid of the holding device 28, which can be pivoted by the at least one pivot actuator 31, 32, the load 2 can be tilted, swiveled, and / or inclined so that the load 2 can be positioned during building construction and / or building renovation. For example, pivoting, tilting, and / or inclining the load 2 is advantageous when, for example, a roof overhang 51 must be driven under. In this case, the load 2 can be tilted toward a horizontal orientation in order to drive under the roof overhang 51. The load 2 can then be brought back into a vertical direction so that the load 2 can be positioned.Tilting in a horizontal direction and then rotating it vertically is useful, for example, for slab-shaped building components and / or wall elements. For other building elements, it may also be useful to first orient the building element as load 2 vertically and then bring it into a horizontal orientation. The pivoting, tilting, and / or inclination of load 2 always depends on the requirements and the shape of load 2.

[0068] As already described, the load-handling device 1 comprises at least one pivot actuator 31, 32 for moving or pivoting the holding device 28, which can be designed, for example, as a hydraulic actuator. With the aid of the at least one pivot actuator 31, 32, the holding device 28 can be rotated about the at least one pivot joint 29, 30. As can be seen here, the load-handling device 1 comprises two pivot joints 29, 30 and / or two pivot actuators 31, 32.

[0069] Furthermore, the holding device 28 comprises a longitudinal beam 33 and an adapter unit 34. The longitudinal beam 33 is arranged rotatably, pivotably, tiltably, inclinably and / or movably on the base frame 3 by means of the at least one pivot joint 29, 30.

[0070] According to the present embodiment, at least one lever 35, 36 is arranged on the longitudinal beam 33, on which the at least one pivot actuator 31, 32 is arranged. With the aid of the at least one lever 35, 36, the at least one pivot actuator 31, 32 can exert a higher torque on the longitudinal beam 33 and consequently on the holding device 28. The at least one lever 35, 36 extends away from the longitudinal beam 33. Since the load-handling device 1 here comprises two pivot actuators 31, 32, two levers 35, 36 are also present. Advantageously, each pivot actuator 31, 32 is assigned a lever 35, 36.

[0071] The adapter unit 34 is arranged or is arranged on the longitudinal beam 33. The adapter unit 34 serves to receive the load 2. The adapter unit 34 has at least one fastening element 37, 38, by means of which the load 2 can be arranged on the adapter unit 34. By means of the at least one fastening element 37, 38, the load 2 can, for example, be screwed and / or clamped to the adapter unit 34. In particular, by means of the at least one fastening element 37, 38, a connection, in particular a detachable, positive and / or non-positive connection, can be formed between the load 2 and the adapter unit 34. For example, the at least one fastening element 37, 38 can be a clamp and / or a screw plate.

[0072] In order to arrange the adapter unit 34 on the longitudinal beam 33, the adapter unit 34 has a connecting unit 39. The adapter unit 34 can be connected to the longitudinal beam 33 by means of the connecting unit 39. A positive and / or non-positive connection can be formed between the connecting unit 39 and the longitudinal beam 33. It is advantageous if the connecting unit 39 is designed such that the pivoting movement of the longitudinal beam 33 is transmitted directly and / or without play to the adapter unit in order to ensure precise positioning of the load 2.

[0073] Advantageously, the connecting unit 39 is designed such that the adapter unit 34 can be detached from the longitudinal beam 33. This allows the adapter unit 34 to be removed from the load-bearing device 1 or from the base frame 3 when it is not needed or interferes with a work step.

[0074] Furthermore, the adapter unit 34 comprises a beam 54 on which the connecting unit 39 and / or the at least one fastening element 37, 38 is arranged. It is advantageous if the beam 54 has a plurality of fixing openings 55, whereby for the sake of clarity only three fixing openings 55 are provided with a reference numeral here. With the help of the fixing openings 55, the connecting unit 39 can be moved along the beam 54 and fixed at any location. For fixing, for example, a bolt (not shown here) is inserted through the fixing openings 55 through the connecting unit 39 and through the beam 54, so that the connecting unit 39 is fixed to the beam 54. This allows the height of the connecting unit 39 to be adjusted. As can be seen here, the connecting unit 39 is fixed to the beam 54 with two bolts. As a result, the height of the load 2 arranged on the adapter unit 34 can be adjusted.

[0075] In addition or alternatively to the height adjustability of the connecting unit 39 on the beam 54, at least one fastening element 37, 38 can also be adjusted in height on the beam 54. At least one fastening element 37, 38 can be moved and fixed along the beam 54. The at least one fastening element 37, 38 can also be fixed to the beam 54 by means of a bolt. As can be seen in this exemplary embodiment, the second fastening element 38 can be moved and fixed along the beam 54. The second fastening element 38 can also be fixed to the beam 54 by means of a fixing opening 55 and by means of a bolt. Additionally or alternatively, the first fastening element 37 can also be moved and fixed. This makes it possible to accommodate different load sizes.

[0076] Additionally or alternatively, the beam 54 can also be designed as a telescopic beam, allowing the beam 54 to be adjusted in length. The fixing openings 55, into which bolts can be inserted, can also be used to fix the length of the beam 54.

[0077] It is advantageous if several, for example two, adapter units 34 are arranged on the longitudinal beam 33. For example, the adapter units 34 can be arranged in the region of the ends of the longitudinal beam 33. The number of adapter units 34 arranged on the longitudinal beam 33 depends on the size and / or weight of the load 2. Thanks to the detachable connecting unit 39, one or more adapter units 39 can be easily arranged on the longitudinal beam 33 and removed again. It is advantageous in this case if the one or more adapter units 34 are first connected to the load 2 and only then are the one or more adapter units 34 arranged on the longitudinal beam 33.

[0078] According to the present exemplary embodiment, the at least one longitudinal member 14, 15, the at least one vertical member 16, 17 and / or the at least one cross member 18 - 21 comprises through-openings 40 - 42. The stop means 4, 5 can be guided into and / or out of the at least one longitudinal member 14, 15, the at least one vertical member 16, 17 and / or the at least one cross member 18 - 21 through the through-openings 40 - 42. The stop means 4, 5 thus runs in an interior of the at least one longitudinal member 14, 15, the at least one vertical member 16, 17 and / or the at least one cross member 18 - 21. For this purpose, it is advantageous if the at least one longitudinal member 14, 15, the at least one vertical member 16, 17 and / or the at least one cross member 18 - 21 are designed in the shape of a frame, tube and / or profile.

[0079] In this exemplary embodiment, the first vertical support 16 has the first through-opening 40, and the second through-opening 41 is arranged in the upper region of the base frame 3. The second through-opening 41 is arranged in the first vertical support 16, in the second longitudinal support 15, and / or in the second cross member 19. The first lifting means 4 is guided into and out of at least the first vertical support 16 through the through-openings 40, 41. The same applies to the second lifting means 5. This is guided in and out through the third through-opening 42 and a through-opening concealed here by the second lifting actuator 7. By guiding the at least one lifting means 4, 5 in this way, they can be guided in a protected manner. Furthermore, space can be saved.

[0080] Furthermore, the at least one lever 35, 36 has a passage channel 43, 44 through which the at least one stop means 4, 5 is guided. This allows the at least one stop means 4, 5 to be guided past the holding device 28 and / or the longitudinal beam 33 and / or over the longitudinal beam 33. Since two levers 35, 36 are shown here, two passage channels 43, 44 are also present.

[0081] The first and fourth deflection units 9, 12 are arranged here on the longitudinal beam 33 and / or are arranged in the passage channels 43, 44.

[0082] Figure 4 shows a side view of the adapter unit 34. The connecting unit 39 comprises a bolt 45, a first stop 46 and a second stop 47. In addition, the adapter unit 34 comprises a vertical bar 48. The fastening elements 37, 38 are arranged on the vertical bar 48.

[0083] The longitudinal beam 33 can be clamped between the bolt 45, the two stops 46, 47 and the vertical beam 48, so that the adapter unit 34 is connected to the longitudinal beam 33.

[0084] The bolt 45 can be arranged in holes (not shown here) in the stops 46, 47 and preferably releasably secured. The bolt 45 can thus be removed to detach the adapter unit 34 from the longitudinal beam 33.

[0085] Figure 5 now shows the load 2 arranged on the holding device 28. Upon actuation of the first swivel actuator 31 shown here, the load 2 can be swiveled. In this case, the longitudinal beam 33 and thus the adapter unit 34 on which the load 2 is arranged are swiveled via the first lever 35.

[0086] Figure 6shows a method step in which the load 2 is arranged on a building 49. The load-handling device 1 hangs by means of at least one chain 52 on a support means 13, which is designed here as a crane.

[0087] Furthermore, the load 2 hangs on the load-carrying device 1 by means of the at least one lifting means 4, 5. The load 2 can be lifted or lowered by means of the at least one lifting actuator 6, 7.

[0088] For example, load 2 was positioned against a building wall 53 shown here. Additionally or alternatively, load 2 can be lowered until it is in the correct position.

[0089] Furthermore, a roof 50 and an overhang 51 of the building 49 are shown here. The base frame 3 shown here, or rather the C-shape of the base frame 3, allows the load-handling device 1 and, consequently, the load 2 to be transported very close to the building 49. The overhang 51 engages the base frame 3, or rather the C-shape of the base frame 3. The base frame 3 engages around the overhang 51.

[0090] In this view, behind the first lifting actuator 6, a supply unit 56 can be seen, which is arranged on the base frame 3. The supply unit 56 is arranged here on an upper side of the base frame 3. When the load 2 is suspended, as can be seen here, the load 2 is arranged in the area of ​​the underside. The supply unit 56 is arranged on the upper side opposite the underside. The supply unit 56 can be used to supply the load handling device 1 with energy. If the actuators of the load handling device 1 are hydraulic actuators, for example, the supply unit 56 can provide the oil pressure, for example.

[0091] Figure 7 shows a method step in which the load 2 is pivoted in order to arrange it on the building 49. A first load 2a is already arranged on the building wall 53. For example, the first load 2a was Figure 6 shown method arranged on the building wall 53.

[0092] With the aid of the holding device 28 and the at least one pivot actuator 31, 32, the second load 2b shown here is pivoted in a horizontal direction. This allows the second load 2b to be placed on the building wall 53 and below the roof overhang 51. As shown here, the second load 2b is already partially located below the roof overhang 51, so that the second load 2b can now be pivoted back in the vertical direction until it is aligned parallel to the building wall 53. At the same time, the second load 2b can be moved further toward the building wall 53 by the support means 13. The support means 13 is designed here as a mobile crane.

[0093] The load 2 can be lowered or lifted and / or pivoted by the load handling device 1 described in the figures, so that the load handling device 1 can be used effectively and universally.

[0094] Figure 8shows the load-handling device 1 in a rear view. The load 2 is not shown here. However, the two adapter units 34a, 34b arranged on the longitudinal beam 33 can be seen. These are arranged spaced apart from each other on the longitudinal beam 33 by means of the two connecting units 39a, 39b.

[0095] Furthermore, this exemplary embodiment shows a chain suspension 57, by means of which the load-handling device 1 can be suspended from the support means 13, for example, on a crane or a mobile crane. In this exemplary embodiment, the chain suspension 57 itself comprises several chains 52a-52d to enable the load-handling device 1 to be stably suspended. However, the chains 52a-52d are merely examples. In addition to or as an alternative to the chains 52a-52d, tension straps, round slings, slips, and / or ropes can also be used.

[0096] The chain suspension 57 also comprises at least one traction unit 58, the length of which can be varied. If, for example, the length of the traction unit 58 is increased in this exemplary embodiment, the right-hand side of the load-handling device 1 tilts downward. If, on the other hand, the length of the traction unit 58 is reduced in this exemplary embodiment, the right-hand side of the load-handling device 1 pivots upward. By adjusting the length of the traction unit 58, the load 2 can thus be tilted. With the aid of the traction unit 58, the length of the chain suspension 57 can thus be changed at least in sections, namely on the right-hand side here.

[0097] The traction unit 58 can be designed, for example, as a hydraulic cylinder, a pneumatic cylinder, a chain winch, a cable winch and / or an electric linear motor.

[0098] Furthermore, only one traction unit 58 is shown here. The chain suspension 57 can also comprise several traction units 58.

[0099] Furthermore, in this exemplary embodiment, a safety arrangement 59 is assigned to the at least one traction unit 58. The safety arrangement 59 increases safety, namely in the event that the functionality of the traction unit 58 can no longer be guaranteed due to the mass of the load 2 or a technical defect of the traction unit 58.

[0100] The securing arrangement 59 may, for example, comprise at least one chain, a rope, a band, a belt and / or a bracket that bridges the traction unit 58.

[0101] Figure 9 shows a lifting actuator 6, 7 with a pulley 60. Here the first lifting actuator 6 is shown as an example.

[0102] With the help of the pulley block 60, the lifting effect of the lifting actuator 6 on the lifting device 4 is increased. In this exemplary embodiment, the at least one lifting actuator 6, 7 is designed as a hydraulic unit. An advantage of the hydraulic unit is that it can generate large forces. However, the stroke length is limited. With the help of the pulley block 60, the effective stroke length can be increased.

[0103] The pulley block 60 comprises a first and a second roller unit 61, 62, each of which comprises at least one or preferably a plurality of rollers 63, over which the lifting means 4 shown here is guided. The lifting means 4 is arranged at a fastening point 64 on the second roller unit 62. Additionally or alternatively, the fastening point 64 can also be on the base frame 3. The lifting means 4 is fixed relative to the base frame 3 at the end opposite the load 2. Furthermore, the lifting actuator 6 and the second roller unit 62 are arranged on the base frame 3, in particular detachably and / or fixedly and / or immovably. The first roller unit 61 is movable relative to the second roller unit 62. The lifting actuator 6 is coupled to the first roller unit 61 and can move it.Thus, if the first roller unit 61 in this embodiment is moved downward and / or toward the second roller unit 62, the lifting device 4 stored in the pulley block 60 is released, and the load 2 attached to the lifting device 4 is lowered. However, if the first roller unit 61 in this embodiment is moved upward and / or away from the second roller unit 62, the lifting device 4 is stored in the pulley block 60, and the load 2 attached to the lifting device 4 is lifted.

[0104] The pulley 60, the first and / or second roller unit 61, 62 and / or the at least one lifting actuator 6 can be detachably arranged on the base frame 3 so that they can be dismantled for maintenance purposes.

[0105] The lifting actuator 6 and / or the pulley block 60 can, as already described, be arranged on the base frame 3. To save further space, the lifting actuator 6 and / or the pulley block 60 can also be arranged inside or in an interior of the vertical, longitudinal, and / or transverse beams 14-21. These can be tubular and / or profile-shaped for this purpose. List of reference symbols
