Hooklift vehicle

Description

[0001] The invention relates to a hooklift vehicle with a hooklift for loading and / or unloading a container.

[0002] Such hooklift vehicles are known, for example, in the form of trailers or trucks. They make it possible to unload a suitably designed container using the hooklift, particularly from the rear, i.e., behind the hooklift vehicle, or to load it onto the hooklift vehicle from the rear.

[0003] For example, a container can be transported to a construction site using a hooklift truck, unloaded, filled with cargo such as construction debris, and then reloaded onto the hooklift truck and transported away. The same hooklift truck can be used for several containers simultaneously. This allows, for instance, a container to be filled over several days while the hooklift truck is being used at a different location and / or with a different container.

[0004] However, because loading and unloading takes place at the rear of the hooklift vehicle, the use of a hooklift vehicle requires a comparatively large parking space.

[0005] Furthermore, it is common practice, particularly in municipal, agricultural, and construction sectors, to maintain different transport vehicles for various applications. However, this results in very high costs for the provision and maintenance of such a fleet. These costs could be reduced by using multifunctional transport vehicles.

[0006] A hooklift vehicle would therefore be desirable, as it would allow for the loading, unloading and / or transport of common container goods, such as bulk goods, machinery, etc., in a particularly diverse manner.

[0007] From DE 20 2013 103 654 U1, a transport vehicle for picking up and setting down a container is known. A container can be lifted onto the known transport vehicle by means of a hook guided on a carriage.

[0008] A vehicle is known from US patent 2012 / 0025590A1 that can unload a container from the rear. In addition, the container can be tipped sideways.

[0009] US 2004 / 0083671 A1 reveals a container whose side walls can be folded down around a lower axis running parallel to the longitudinal axis.

[0010] US Patent 4,652,201 discloses a swiveling arm mounted on the chassis of a vehicle.

[0011] DE 20 2014 007 007 U1 discloses a device for loading and unloading containers onto or from a frame of a road vehicle having one axle, which has a tiltable container lifting device arranged on the frame of the device, wherein the frame has a section that can be folded downwards about a pivot axis. US 2011 196623 A1 discloses a hook lift on a truck with an articulated arm according to the prior art.

[0012] FR 2 315 409 A1 discloses a hooklift vehicle with a hooklift according to the first part of claim 1.

[0013] The object of the present invention is therefore to provide a hooklift vehicle with extended usage possibilities.

[0014] This problem is solved by a hooklift vehicle with the features of claim 1.

[0015] The hooklift can be specifically designed for loading and / or unloading the container from the rear. The hooklift has multiple arms and can be configured to grip the container at its front.

[0016] Such a hooklift vehicle offers a wide range of uses. For example, the container can be loaded and / or unloaded from the rear. Alternatively, the container can also be tipped backwards using the hooklift. For this purpose, the hooklift vehicle can be configured as a roll-off tipper.

[0017] If the hooklift truck is equipped to tip the loaded container laterally along at least one long side of the truck, the container can also be loaded and / or unloaded along this side, for example, if there is limited space behind the truck. With such a hooklift truck, bulk goods can therefore be tipped along at least one long side in addition to the usual rear unloading of the filled container. Thus, the hooklift truck can also be used as a multi-way tipper.

[0018] Since the hooklift vehicle is designed to be lowered at the rear, mobile work machines, for example, can be driven onto and / or off the hooklift vehicle more easily when it is lowered at the rear.

[0019] Thus, the possible applications of a hooklift vehicle according to the invention are significantly expanded compared to a conventional hooklift vehicle. In both municipal and agricultural sectors, the utilization rate of such a hooklift vehicle can be improved, which can result in considerable cost advantages and / or shorten the amortization period for the user.

[0020] The hooklift vehicle may also have a side-tipping device for tipping the loaded container laterally along at least one longitudinal side of the hooklift vehicle.

[0021] The side-tipping device can be configured to tip the container either to the left or the right side of the hooklift vehicle. "Left side" or "right side" refers to the respective side when viewed along the usual direction of travel of the hooklift vehicle.

[0022] The container can therefore be loaded and / or unloaded from either the left or the right side. This allows the hooklift vehicle to also be used as a further improved multi-way tipper, especially as a three-way tipper, for example in agriculture.

[0023] It is conceivable, in particular, that the side-tipping device has at least one, and preferably one or two, tipping cylinders. These tipping cylinders can be hydraulically or pneumatically actuated, for example. Such tipping cylinders allow for a high stroke while requiring minimal space, especially in terms of height. This ensures sufficient ground clearance.

[0024] At least one of the tipping cylinders can be designed as a double-acting cylinder. This allows the tipping cylinder, particularly in its retracted position, to also be used to secure the side tipping device, the hooklift, and / or the container to the chassis of the hooklift vehicle.

[0025] The side-tipping device comprises a laterally tilting subframe on which the hooklift is mounted. In particular, at least one tipping cylinder can be arranged between the chassis and the subframe. The at least one tipping cylinder can then – by extending it – tip the subframe, along with the hooklift and any container mounted on it, to the side, or – by retracting it – return the subframe, hooklift, and any container to its horizontal starting position. The at least one double-acting tipping cylinder can also, for example, before actuating the hooklift, particularly in its retracted position, clamp the subframe onto the chassis, thereby securing the hooklift and thus also the container against lateral and / or rearward tipping.

[0026] The side-tipping device can have at least two locking mechanisms, preferably bolt or clamp locks, designed to rotatably secure the loaded container to one longitudinal side of the hooklift vehicle, particularly by rotatably fixing the intermediate frame. Thus, the container can be rotatably fixed to the hooklift vehicle, especially its chassis, on this longitudinal side, particularly by means of the intermediate frame. If the tipping cylinder(s) are then extended, the container can be tipped towards this longitudinal side, particularly by means of the intermediate frame. One or more of the locking mechanisms can be hydraulically and / or pneumatically actuated. In this case, the side-tipping process can be automated and / or controlled "at the push of a button."

[0027] It is particularly advantageous if at least four such locking mechanisms are provided, especially at least two locking mechanisms on each of the two longitudinal sides of the hooklift vehicle. This makes it possible to selectively fix the container, particularly by means of the intermediate frame, to either of the two longitudinal sides of the hooklift vehicle so that lateral tipping is enabled in a particularly simple manner, either to the right or to the left. It is also conceivable that, alternatively or additionally, locking mechanisms along both longitudinal sides are used to secure the container or the intermediate frame to the chassis. Additionally, particularly in this case, at least one shut-off valve can be provided to deactivate one or more of the tipping cylinders.

[0028] In a particularly preferred class of embodiments of the invention, the hooklift is telescopic. For this purpose, the hooklift can be telescopic along a longitudinal direction of the hooklift vehicle and / or perpendicularly or substantially perpendicular to this direction, in particular vertically. In particular, the hooklift can be vertically telescopic such that the height of its hook can be adjusted to one or more standard heights, for example 1570 mm and / or 900 mm, of container handles. The hooklift can be hydraulically and / or pneumatically telescopic.

[0029] This means the hooklift truck can be used for different types of containers, especially containers of varying lengths and / or containers with handles positioned at different heights. This further expands the truck's range of applications. Loading and / or unloading the container can be simplified.

[0030] While the hook of the hook lift typically has the form of an open, approximately elliptical ring with which it can grip the container at a suitably complementary handle element, it is also conceivable to design the hook in a different form. For example, the hook can alternatively or additionally be designed as a locking element, for example in the form of a carabiner, and / or in the form of pincers, in particular with one or more parts that are movable relative to each other. The hook can particularly preferably be designed as an automatic hook.

[0031] The hooklift vehicle has a rear-lowering chassis. Preferably, the chassis can be lowered towards the ground at the rear. This can facilitate loading and / or unloading the container. It also allows the container to be loaded and unloaded at a lower maximum incline from the horizontal. Furthermore, this reduces the parking space required.

[0032] The chassis features a pendulum axle assembly, an air spring assembly and / or a parabolic spring assembly, and the drawbar of the hooklift vehicle is designed to pivot relative to the chassis.

[0033] Furthermore, the hooklift vehicle may be provided with an adjustable lighting bracket, particularly at the rear, which is movable along the chassis. This allows the hooklift vehicle to be adapted to different containers, especially those of different lengths. Preferably, the lighting bracket can be electrically, hydraulically, and / or pneumatically movable.

[0034] It is also conceivable that the hooklift vehicle is configured as a trailer or a truck. As a trailer, it can be used with a wide variety of towing vehicles. If it is configured as a truck, no additional towing vehicle is required.

[0035] The hooklift vehicle can be configured with one, two, or three axles in its loading section, depending particularly on the intended maximum payload. It is understood that, especially in the case of a hooklift vehicle designed as a truck, additional axles may be provided outside the loading section, particularly in the area of ​​the driver's cab.

[0036] A particularly versatile container may have at least one hinged and foldable side wall and one hinged and foldable rear wall.

[0037] At least one axle of its loading section can be adjustable along the longitudinal direction, in particular hydraulically adjustable. If the hooklift vehicle is designed as a trailer, for example, weight balancing can be achieved by adjusting the axle. In particular, the vertical load acting on a drawbar eye of the trailer can be adjusted.

[0038] The hooklift vehicle is particularly easy to operate if at least one of its functionalities, in particular loading, unloading, rear lowering and / or side tipping of the hooklift vehicle, opening and / or closing of the container, opening and / or closing of at least one of the locking mechanisms, adjusting the axle and / or adjusting the lighting bracket, is remotely controllable, in particular by means of a radio remote control. Generally, it is conceivable that at least one of the actuated elements, in particular the electrically, hydraulically and / or pneumatically actuated elements, can be remotely controllable. For example, in the case of hydraulically and / or pneumatically actuated elements, a respective pneumatic or hydraulic actuating cylinder of the element in question can be remotely controllable.

[0039] It is also conceivable, for example, that the hooklift vehicle, in particular the radio remote control, has a selector switch with which at least one of these functionalities can be triggered and / or controlled.

[0040] A container for a hooklift vehicle according to the invention enables both rear unloading and / or loading by means of a hooklift of the hooklift vehicle and use of the hooklift vehicle as a side tipper, in particular as a two-way tipper or – especially if both side walls are openable – as a three-way tipper. The container has a side wall, which can also be divided into several parts, in particular two, so that the side wall can be opened in two or more parts, in particular wings. If at least one side wall is foldable, then, for example, non-poundable goods can also be easily loaded and unloaded.

[0041] In such a container, it may be provided that its rear side wall is hinged and / or foldable, preferably both hinged and foldable, and / or pivotable to at least one side. In particular, the rear side wall may pivot to the left and / or right, similar to a door. It is also conceivable that the rear side wall is divided into multiple sections; for example, it may be formed as two leaves. In this case, the rear side wall can be opened similarly to a double door by pivoting one leaf of the wall to the left and the other leaf to the right.

[0042] This allows the rear side panel to be opened as needed, depending on the application. For example, it can be folded down to create a loading ramp, such as for loading mobile machinery. For unloading bulk goods, the rear side panel can be opened by swinging. If, for example, larger goods are to be loaded or unloaded, the rear side panel can also be pivoted to the left or right as required, or – in the case of a double-leaf side panel – one leaf can be pivoted to the left and the other to the right. It is particularly conceivable that one or more side panels can be opened via a preferably controllable locking mechanism and / or a central locking system. In particular, it can also be provided that the radio remote control and / or the hooklift vehicle are configured to open and / or close one or more of the container's side panels.

[0043] Furthermore, it is conceivable that, depending on the intended main area of ​​use, the container is designed as a skip or as a platform container.

[0044] Containers can also be used with the hooklift vehicle if they are designed as halfpipe containers, rubble skips, chipping skips (e.g. with grids and / or tarpaulins), liquid containers or the like.

[0045] At least one, in particular removable, access ramp can be arranged on the container and / or the hooklift vehicle. Preferably, two such access ramps can be provided. For this purpose, the container and / or the hooklift vehicle can have a corresponding number of ramp brackets for receiving and transporting the access ramps. Such access ramps can further facilitate driving into and / or out of the container, for example, by mobile machinery.

[0046] Further features and advantages of the invention will become apparent from the following detailed description of the embodiments of the invention, with reference to the figures of the drawing which show details essential to the invention, as well as from the claims.

[0047] The features shown in the drawing are presented in such a way that the special features according to the invention can be clearly made visible.

[0049] To facilitate understanding of the invention, unless otherwise stated, corresponding elements in all figures of the drawing and in the following description are designated by the same reference numerals.

[0050] Fig. 1 Figure 1 shows a first hooklift vehicle 10. In this embodiment, the hooklift vehicle 10 is designed as a trailer, which is typically moved in one direction F. A container 12 is loaded onto the hooklift vehicle 10. The container 12 is designed as a skip.

[0051] The hooklift vehicle 10 has a hooklift 14 which is arranged on an intermediate frame 16. The hooklift 14 is designed to be telescopic in the longitudinal direction of the intermediate frame 16. In the Fig. 1 In the depicted state, the intermediate frame 16 rests on a chassis 18.

[0052] The chassis 18 features an adjustment cylinder (in Fig. 1 (not visible) along the longitudinal direction L corresponding to the direction of travel F on a (in Fig. 1 (also not visible) guide rail adjustable, in particular hydraulically adjustable, axis 19 on.

[0053] Between the subframe 16 and the chassis 18 are two tipping cylinders 20 (see also Fig. 8 ) arranged, of which in the side view according to Fig. 1 Only one tilting cylinder 20 is visible. The tilting cylinders 20 are designed as double-acting hydraulic cylinders. In the Fig. 1 In the depicted state, in which the tilting cylinders 20 are in the retracted position, the tilting cylinders 20 clamp the subframe 16 onto the chassis 18 and thereby fix the subframe 16 to the chassis 18. The tilting cylinders 20 can be designed as hydraulic cylinders.

[0054] On both the left and right sides of the intermediate frame 16, guide rollers 17 are arranged in its rear area for guiding the container 12 during unloading and / or loading from or onto the hooklift vehicle 10.

[0055] Locking devices 21 are arranged in all corner areas of the chassis 18. Of these, the following are shown in the side view of the Fig. 1 Only two locking mechanisms 21 are shown. In this embodiment, the locking mechanisms 21 are designed as, in particular, controllable bolt locking mechanisms. The locking mechanisms 21 thus detachably connect the intermediate frame 16 to the chassis 18. In the closed or locked state, they each form pivot bearings. If the respective locking mechanisms 21 on a first longitudinal side of the hooklift vehicle 10 are locked by means of suitable bolts and the corresponding locking mechanisms 21 on the other longitudinal side of the hooklift vehicle 10 are opened, the intermediate frame 16 can be tilted towards the first longitudinal side by extending the tilting cylinders 20.

[0056] The intermediate frame 16, in conjunction with the tipping cylinders 20 and the locking devices 21, forms a side-tipping device 22 for selectively tipping the loaded container 12 laterally along either the first or the other longitudinal side. In other words, the side-tipping device 22 allows the loaded container 12 to be tipped either to the left or right longitudinal side of the hooklift vehicle 10.

[0057] Furthermore, the chassis 18 features a two-axle pendulum axle assembly 23. A drawbar 24 of the chassis 18 is pivotably mounted relative to the rest of the chassis 18 by means of a connection 26 and a pivoting mechanism 28 comprising a hydraulic cylinder. Thus, the chassis 18 – as will be explained in more detail below – is designed to be lowered as a whole. In particular, the rear portion of the chassis 18, corresponding to the direction of travel F, can be lowered towards the ground 29.

[0058] To connect to a towing vehicle (in Fig. 1 (Not shown) the hooklift vehicle 10 has a connecting section 30 with a towing eye 32 on its front side, corresponding to the direction of travel F. The position of the connecting section 30 – and thus the towing eye 32 – can be adjusted along the longitudinal direction L and in the vertical direction H, which is orthogonal to the longitudinal direction L, by means of two flanges 34. This allows the towing eye 32, and therefore the hooklift vehicle 10, to be adapted to different towing vehicles as required.

[0059] By means of a support 36 arranged on the drawbar 24, the hooklift vehicle 10 can be supported on the ground 29, especially when the towing vehicle is not attached.

[0060] Furthermore, the hooklift vehicle 10, in particular the chassis 18, has a lighting bracket 38 on its rear side. The lighting bracket 38 is arranged to be displaceable along the longitudinal direction L on the rest of the chassis 18. In this embodiment, it is connected by means of a hydraulic cylinder (in Fig. 1 (not visible) movable. In alternative embodiments, it can also be designed to be fixed, for example by means of clamping devices or by means of screws in conjunction with rows of holes arranged in the longitudinal direction L and incorporated into the rest of the chassis 18.

[0061] Support wheels 39 are also visible at the rear of the hooklift vehicle 10. In alternative embodiments of the invention, support elements, for example support feet, can be provided instead of the support wheels 39. The support wheels 39 serve in particular to support the hooklift vehicle 10, especially when the chassis 18 is lowered towards the ground at the rear. The support wheels 39 also help to prevent the towing vehicle from lifting and / or tipping, especially during the loading and / or unloading of the container 12.

[0062] The hooklift vehicle 10 can be operated remotely by means of a radio remote control 40. For this purpose, the hooklift vehicle 10 has a receiver and control unit 42 on its chassis 18. The receiver and control unit 42 is configured to receive and evaluate control signals 44 transmitted by radio from the radio remote control 40. The receiver and control unit 42 is further configured to actuate the tilting cylinders 20, the swiveling mechanism 28, the hooklift 14, and the locking mechanisms 21 based on these control signals 44, in particular to open or close them as required on each longitudinal side of the hooklift vehicle 10. It is also configured to actuate all other operable elements associated with the container 12, for example, the hydraulic cylinder for moving the lighting bracket 38 and / or the adjusting cylinder of the adjustable axle 19, as required.

[0063] The hook lift 14 has a hook 46 at one end. The hook 46 has an elliptical, open inner cross-section. A spring-loaded locking element 47 serves to automatically close the opening of the hook 46. Overall, the hook 46 is designed as an automatic hook.

[0064] For the detachable connection of the container 12 to the hook lift 14, the container 12 has a handle element 48. The handle element 48 is semi-ring-shaped and is arranged on the container 12 in a position adapted to the hook 46 or the hook lift 14.

[0065] Container 12 has several side walls, in particular two side walls 50 on each of its two longitudinal sides, a rear side wall 52 on its back and a front side wall 54 on its front.

[0066] The side wall panels 50 are secured by several wall panel locks 56, of which, for illustrative purposes, are shown in the illustration of the Fig. 1 Only four side wall closures 56 are marked with reference symbols, and the side wall hinges 58 are arranged on the container 12 in a pivotable and foldable manner, of which, for illustrative reasons, only one side wall hinge 58 is provided with a reference symbol. The side walls 50 are each divided into two parts.

[0067] The rear side wall 52 is arranged on the rest of the container 12 in a way that allows it to be pivoted, folded down, and laterally pivoted by means of a rear wall lock 60, several rear wall hinges 62, and a rear wall pivot joint 64. In particular, it can be used as a loading ramp when folded down.

[0068] Adjacent to the front side wall 54 is a support wall 55 of a main frame supporting the container. The handle 48 is arranged on the support wall 55 at a height position aligned with the hook lift 14, in particular with the position of the hook 46. In this embodiment, the support wall 55 is higher than the height position of the handle 48.

[0069] Furthermore, on the underside of the container 12, in the area of ​​the rear side wall 52, floor rollers 66 are arranged, by which the container 12 can roll on the ground 29, particularly during unloading and / or during loading.

[0070] In Fig. 2 bis Fig. 9 Further possible uses or applications of the hooklift vehicle 10 according to the invention are given as examples ( Fig. 1 ) explained in more detail.

[0071] Fig. 2 shows a position of the hooklift vehicle 10 of the Fig. 1 , in which, for example, a mobile work machine (in Fig. 2 (not shown) can be easily loaded and / or unloaded.

[0072] It can be seen that the chassis 18 is lowered at the rear towards the ground 29 by means of the pendulum axle assembly 23 and the pivoting mechanism 28 arranged on the drawbar 24. Due to the lowering, the container 12 is also inclined towards the horizontal; in particular, it too is lowered at the rear towards the ground 29.

[0073] By partially retracting the telescopic hooklift 14, the container 12 is approximately half unloaded from the chassis 18. Additionally, the rear side wall 52 is folded down towards the ground, thus forming a loading ramp.

[0074] Thus, the mobile work machine or the cargo can be driven into or out of the container 12 via the rear side wall 52.

[0075] Fig. 3 The hooklift vehicle 10 is shown in a position during the unloading of the container 12. This position can also be used for or during the loading of the container 12 onto the hooklift vehicle 10.

[0076] According to the position of the hooklift vehicle 10 according to Fig. 2 is also the case with the one in Fig. 3 In the depicted state of the hooklift vehicle 10, the drawbar 24 pivots against the chassis 18, so that the rear of the hooklift vehicle 10 is lowered towards the ground 29. This lowering reduces the parking space required behind the hooklift vehicle 10 in this application. Furthermore, the maximum inclination of the container to the horizontal during unloading is reduced.

[0077] The Fig. 3 It can also be seen that the L-shaped hook lift 14 in the side view is operated by two hydraulic cylinders 68, of which the illustration shows the Fig. 3 Only one is recognizable as being driven.

[0078] Container 12 can thus be unloaded as follows (the same applies in reverse order to load container 12): First, the rear of the hooklift vehicle 10 or the chassis 18 is lowered. The telescopic hooklift 14 is fully retracted so that container 12 is moved beyond the rear end of the hooklift vehicle 10. By extending the hydraulic cylinders 68, the hooklift 14 is raised, causing container 12 to roll off the hooklift vehicle 10 on its floor rollers 66 in a pivoting motion.

[0079] Fig. 4 This represents an alternative use case for unloading and loading container 12 onto and from hooklift vehicle 10. This alternative largely corresponds to the use case according to Fig. 3 The only difference is that in this alternative, the drawbar 24 is not pivoted against the chassis 18. Therefore, the hooklift vehicle 10 is not lowered at the rear. However, even in this case, the container 12 can be positioned according to the specifications in relation to Fig.3 The described procedure is used for unloading and loading. During the erection of the hooklift 14, the container 12 is tilted more sharply against the horizontal than in the previously described application.

[0080] Fig. 5 shows the final state of the in relation to Fig. 4 The described application scenario occurs after the container 12 has been completely unloaded from the hooklift vehicle 10, but before the hook 46 is unhooked from the handle element 48. The Fig. 5 The depicted state can also serve as the initial state before loading the container 12 onto the hooklift vehicle 10.

[0081] Fig. 6 This shows an application where, for example, bulk materials can be unloaded or tipped from the rear. For this purpose, the hooklift vehicle 10 is in its raised position.

[0082] The hooklift 14 has an upper arm section 70, which is articulated to a lower arm section 74 via a joint 72. The upper arm section 70, together with the joint 72 and the lower arm section 74, forms an articulated arm. The lower arm section 74 is in turn articulated at its rear end to the intermediate frame 16. The hydraulic cylinder 68 engages the upper arm section 70.

[0083] By means of several container locks (see Fig. 7a und 7b ) and by means of hook 46, container 12 is secured to hook lift 14. A (in Fig. 6 In this application, the arm locking mechanism (not shown in detail) additionally secures the lower arm section 74 to the underside of the container 12, thus preventing the hook lift 14 from buckling during the erection of the container 12. For this purpose, the container 12 can have one or more T- or U-profiles on its underside, into which, for example, a controllable bolt of the arm locking mechanism can engage or from which it can be released.

[0084] By extending the hydraulic cylinder 68, the container 12 is now erected and tipped towards the rear of the hooklift vehicle 10.

[0085] A schematic detail view shows Fig. 7a the hooklift 14 of the hooklift vehicle 10 ( Fig. 1 In the illustrated state, the hook lift 14 rests on the intermediate frame 16. It can also be seen that the hydraulic cylinder 68 engages the upper arm section 70.

[0086] Furthermore, several container locks can be seen, in particular arranged along the longitudinal sides of the intermediate frame 16, of which in particular one, in particular a rear, container lock 76 and one front container lock 77 are shown in the illustration of the Fig. 7a are marked. By means of the container locks, in particular the container locks 76, 77, the container can be detachably fixed to the intermediate frame 16.

[0087] In an alternative embodiment, the hooklift vehicle may only have rear container locks 76.

[0088] This shows Fig. 7b An exemplary perspective view of the front container locking mechanism 77, which is designed as a hydraulically actuated bolt locking mechanism.

[0089] At least one of the container locks 76, 77 can also be designed as a manually operated bolt lock. For this purpose, it can have a manually removable and / or manually insertable locking pin. This allows costs to be reduced.

[0090] At least one of the locks 21 ( Fig. 1 The container locks 76, 77 may have a status sensor. The status sensor may be configured to detect the state in which the respective lock 21 or container lock 76, 77 is located. In particular, it may be configured to detect whether it is in a locked or unlocked state.

[0091] The status sensor may include a proximity switch and / or be designed as a proximity switch. In particular, it may be designed as an electronic sensor.

[0092] In particular, four condition sensors can be provided. In general, each of the locking devices 21 and / or each of the container locking devices 76, 77 can be equipped with such a condition sensor.

[0093] The condition sensor can be connected to a central control unit of the hooklift vehicle 10.

[0094] The condition sensor and / or the central control unit can be configured to enable and / or disable one of the functionalities of the hooklift vehicle 10, for example, tipping the container to the rear and / or to one of its long sides. In particular, the enabling or disabling can occur depending on the state of the respective locking mechanism 21 or container locking mechanism 76, 77, as detected, in particular, by the condition sensor.

[0095] This prevents incorrect operation of the hooklift vehicle 10. In particular, it prevents a user of the hooklift vehicle 10 from attempting to tip the container backwards or to the side while the respective function is (still) blocked by one or more of the locking mechanisms 21 and / or the container locks 76, 77. Especially with manually operated locking mechanisms 21 or container locks 76, 77, this prevents damage to the hooklift vehicle 10 in a cost-effective manner.

[0096] Fig. 8 Figure 10 shows the hooklift vehicle 10 in a side view with container 12 tipped to the left. In this position, the hooklift vehicle 10 can be used as a side tipper, for example for side dumping of bulk material.

[0097] Particularly visible are the two tilting cylinders 20, which are fully extended in this state. The tilting cylinders 20 engage the intermediate frame 16 via rocker arms 78.

[0098] The locking devices 21 located along the left longitudinal side of the hooklift vehicle 10 are in the Fig. 8 The depicted state is locked. Thus, the intermediate frame 16, and therefore also the container 12, can be tipped to the left side of the hooklift vehicle 10, or has already been tipped.

[0099] Fig. 9 The hooklift vehicle 10 is shown from the rear in the position according to Fig. 8 . The tilt of container 12 to the left is particularly noticeable.

[0100] It can also be seen that when tipping sideways, the intermediate frame 16, together with the hooklift 14, is tipped sideways. For this purpose, the tipping cylinders 20 with the tipping levers 78 are supported on the chassis 18 and lift the intermediate frame 16 upwards in an approximately central area.

[0101] Fig. 10 and 11 Two further embodiments of the invention in the form of hooklift vehicles 110 are shown ( Fig. 10 ) and 210 ( Fig. 11 The illustrations are schematic to highlight the specific principles underlying these embodiments. Unless otherwise described, features of the hooklift vehicle 10 may be implemented analogously in the hooklift vehicles 110 and / or 210.

[0102] Both hooklift vehicles 110 and 210 are designed as trailers, although a version as a truck is also conceivable in principle.

[0103] These designs are particularly distinguished by the fact that a pendulum axle assembly and a pivoting drawbar are not required. This can result in cost advantages. These designs are therefore preferably used for smaller trailers, for example, car trailers.

[0104] Both embodiments have in common that their respective chassis 18 has a continuous drawbar 24. Furthermore, they both have an axle 19 designed as a tandem axle. The axle 19 can, in turn, be adjustable.

[0105] A middle frame 80 is arranged between the intermediate frame 16, which is essentially analogous to the hook lift device 10, with the hook lift 14, and the chassis 18.

[0106] The hooklift vehicle 110 has two suitably shaped tipping cylinders 20, in particular one tipping cylinder 20 in the area of ​​the axle 19 and a tipping cylinder 20 located further forward. This front tipping cylinder 20 connects the central frame 80 to the chassis 18.

[0107] The hooklift vehicle 210 has only one tipping cylinder 20 located near the axle.

[0108] With the exception of the front tipping cylinder 20, the remaining tipping cylinders 20 connect the chassis 18 to the intermediate frame 16 and / or to the hook lift 14.

[0109] Both embodiments also have several locking mechanisms 21, which can be designed essentially analogously to the locking mechanisms 21 of the hooklift vehicle 10.

[0110] In both hooklift vehicles 110, 210, the intermediate frame 16 together with the hooklift 14 - and thus also any loaded container - can be tipped sideways by actuating the respective axle-adjacent tipping cylinder 20, whereby along one longitudinal side of the respective chassis 18 locking mechanisms 21 between the intermediate frame 16 and the intermediate frame 80 are closed and along the other longitudinal side are opened.

[0111] The hooklift device 110 has, particularly in the area of ​​the axle 19, one or more rows, specifically two rows, of locking devices 21, which detachably and rotatably secure or lock the intermediate frame 80 to the chassis 18. Selectively, by means of one of these rows of locking devices 21 and by actuating the front tilting cylinder 20, the intermediate frame 80 and thus the subframe 16 together with the hooklift 14 can be lowered at the rear of the hooklift device 110.

[0112] A rear-end lowering can also be achieved with the hooklift device 210. For this, the front locking mechanism 79 must be opened and all locking mechanisms 21, in particular the single row of locking mechanisms 21 between the center frame 80 and the chassis 18, must be closed. When the axle-adjacent tipping cylinder 20 is now actuated, the center frame 80, and thus the intermediate frame 16, is lowered via the row of locking mechanisms 21 and therefore at the rear.

[0113] Fig. 12 Finally, a fourth hooklift vehicle, 310, is shown. The hooklift vehicle 310 is designed as a truck. In its construction, it largely corresponds to the hooklift vehicle 10 ( Fig. 1 bis Fig. 9 ). A key difference is that instead of the drawbar eye 32, the flanges 34 and the support 36 (each ) Fig. 1 The remaining hooklift vehicle 310 is mounted on a truck chassis with a driver's cab 81, a front axle 82, and a drive unit. Thus, the hooklift vehicle 310 is self-powered and does not require an additional towing vehicle for propulsion.

[0114] Furthermore, Fig. 12 It can be deduced that the hooklift vehicle 310 is designed as a two-axle vehicle in its loading section 84, in particular without taking into account the front axle 82 arranged in the area of ​​the driver's housing 81. Reference symbol list
