Description

[0001] The invention relates to a roll-off container, in particular for transport by roll-off tipper vehicles with hook attachment, wherein the roll-off container has two end-mounted supports, as well as supports designed to support a roll-off container. State of the art

[0002] Roll-off containers, also known as roll-off containers or sliding roll-off containers, are known from the state of the art for a wide range of applications, such as the transport of bulk goods as well as the transport of vehicles.

[0003] This is a mostly open transport container in the shape of a cuboid or parallelepiped or spat, with a generally rectangular base, whereby the container often has a loading flap on one end, but in any case a receptacle on the other end for the engagement of a hook of a roll-off tipper vehicle, also known as a swap body vehicle.

[0004] When loading the roll-off container onto such a roll-off tipper vehicle, a hook arranged on a lifting arm of the vehicle engages in the front-facing receptacle of the roll-off container, lifts it on one side and pulls the container across the ground to the rear of the vehicle, and subsequently over its rear edge onto a suitable loading platform.

[0005] To protect the ground and the container, the roll-off container has rollers on the corresponding lower edge opposite the hook attachment. For this purpose, the rollers protrude downwards from the plane of the container's base. On the side with the hook attachment, however, the container is usually flat to allow it to be easily lifted and / or pulled over the rear loading edge onto a suitably equipped loading platform of the roll-off tipper truck.

[0006] As a result, when the container is placed on a level and horizontal surface, the base of the container is not horizontal in most common designs; rather, the base usually slopes towards the hook attachment point because the container is higher on one side due to the wheels protruding from the base.

[0007] This leads to disadvantages, particularly with simple roll-off container designs, such as the accumulation of rainwater on the side of the hook attachment, where the transport container is usually closed, i.e., without drainage holes, due to its function.

[0008] To solve this problem, when placing the container in the area of ​​the front end, materials such as stones or wooden planks or squared timbers are often placed under the container to compensate for the height difference; however, these may need to be carried separately.

[0009] A relatively complex solution is also described in DE20 2025 102 371U1, in which a roll-off container has a support foot or a roller on each inclined and elastically deformable beam, and in which the load acting on the beams can be determined based on a deformation of the inclined beams. Disclosure of the invention

[0010] The object of the present invention is to provide a simple solution that is improved compared to the prior art, particularly with regard to availability, variability and technical safety.

[0011] The problem is solved according to the invention by the features of the independent claim. Advantageous embodiments of the invention are specified in the dependent claims.

[0012] According to the invention, a roll-off container with supports is provided, in particular for transport by a roll-off tipper vehicle with hook attachment, wherein the roll-off container has a support frame with two longitudinal beams and two end wall beams, which support a transport container with the basic shape of a cuboid or parallelepiped or spat, which is arranged with one end face against the end wall beams, wherein a receptacle, in particular a bracket, for engaging a hook, in particular the hook of a roll-off tipper vehicle, is arranged between the end wall beams, and wherein two rollers are arranged on the opposite end face in the area of ​​a lower edge of the roll-off container, which project downwards by a roller spacing beyond an underside of the transport container with support frame, wherein the end wall beams are oriented vertically and parallel to each other, and wherein the roll-off container has at least two length-adjustable supports which are arranged on the end wall supports and parallel to them and are adjustable parallel to them and in particular downwards by at least the roller distance below an underside of the transport container and support frame.

[0013] In other words, a roll-off container with supports is provided, in which the roll-off container has a support frame which has two essentially L-shaped supports arranged horizontally and parallel to each other, the long legs of which form two longitudinal beams on which a transport container with the basic shape of a cuboid or squash with a preferably essentially rectangular base is arranged, and the short legs of which form two vertically oriented end wall supports, wherein the roll-off container has only two rollers on one side, and on the other side at least two length-adjustable supports which are arranged directly on the end wall supports and parallel to them.

[0014] Such a roll-off container with supports offers a number of advantages, the first of which is the constant availability of supports permanently attached to the roll-off container.

[0015] In order for the roll-off container to be rolled across a surface during loading or unloading, the underside of the container, including its support frame, must have a certain ground clearance, referred to here as the rolling distance, as described earlier. On the opposite, non-rolling side, however, the roll-off container rests directly on the surface with its transport container and / or support frame, unless prevented by any measures.

[0016] As a result, the transport container of the roll-off container has a slope towards the hook attachment, which in turn leads to the previously described common problem of rainwater accumulating on the hook attachment side. This is because roll-off containers typically lack drainage holes in order to be as versatile as possible, for example, for transporting wet mud or fine-grained materials such as fine sand. Frequent and / or persistent puddles, however, promote corrosion of the containers, which are usually made of steel, and thus shorten their lifespan.

[0017] In practice, the roll-off container is therefore usually propped up on preferably wooden planks or squared timbers for horizontal alignment, which, however, must be available or transported separately, which in turn requires appropriate transport securing measures.

[0018] In this case, fixed or permanently attached supports to the roll-off container offer the advantage of always being available.

[0019] Furthermore, length-adjustable supports offer the advantage of being able to tilt the transport container beyond the horizontal towards the side of the rollers, where roll-off containers often have an opening, usually closable by a flap or gate.

[0020] Furthermore, the option to adjust each support individually offers the possibility of compensating for a sloping or uneven surface.

[0021] Furthermore, arranging the supports on the end wall beam offers additional advantages, the first of which is that the end wall beams constitute a load-bearing component of the roll-off container's support frame, to which the lifting mechanism for the roll-off container is attached. The roll-off container is advantageously designed according to DIN 30722, which, in addition to a standardized height for mounting a hook, defines uniform dimensions for roll-off containers and specifies minimum requirements for the construction, wall thickness, and load-bearing capacity of the containers for safe use under heavy loads.

[0022] The end wall supports are designed to absorb comparatively large forces, especially the weight of the filled container, and are therefore suitable for absorbing or transferring the support loads.

[0023] Furthermore, a roll-off container in which the supports are arranged, in particular directly and immediately, on the end wall beams, offers the advantage that this component of the support frame is always present and usually easily accessible, so that the supports can be replaced if necessary or retrofitted to roll-off containers without supports.

[0024] "Immediate" and "direct" in this context means that no other components, such as crossbeams or a wall of the transport container, are located between the support components on the one hand and the end wall beams on the other. A load borne by a support is transferred directly to the appropriately designed end wall beam. Since this is generally the strongest load-bearing component of the roll-off container, force transmission through comparatively weaker components can be avoided. In an advantageous embodiment of the roll-off container with supports, the length-adjustable supports can be locked continuously or discretely to assume a multiple length settings. Advantageously, they are arranged, particularly at a height on an end wall beam, such that a change in length setting results in a change in the pitching angle of the roll-off container.

[0025] Advantageously, the majority of length settings comprise a length setting (i) in which the supports do not extend below the underside of the support frame, and / or a length setting (ii) in which the supports extend below the underside of the support frame by the roller spacing, and / or a length setting (iii) in which the supports extend below the underside of the support frame by the roller spacing plus a distance of at least 2%, in particular 3%, of a length of the roll-off container, and / or a length setting (iv) in which the supports extend below the underside of the support frame by the roller spacing plus a distance of at least 6%, in particular 8%, of a length of the roll-off container.

[0026] The aforementioned length settings offer the advantages (i) that the supports do not impair the ground clearance of the roll-off container during loading or unloading, nor do they impede its placement in the skip of a roll-off tipper vehicle, (ii) that the roll-off container can be aligned parallel to the ground, preferably horizontally, and (iii) that the roll-off container can be aligned with an inclination to the ground of at least 2%, in particular 3%, in order to provide sufficient gradient for rainwater to drain towards a loading opening.

[0027] In particular, the option to position the roll-off container at a relatively steep incline of 6% or more offers the advantage of significantly lowering the loading edge of the opening. This lowered loading edge makes it easier for vehicles entering the container, such as forklifts, to overcome, often eliminating the need for additional aids to clear the loading edge.

[0028] Furthermore, it is advantageous for the supports to be arranged on a side of an end wall beam that is parallel to the longitudinal side and facing outwards, i.e., in a direction transverse to the longitudinal beams of the roll-off container. If the transport container of the roll-off container has a ladder on its end face next to the end wall beam, the support is advantageously arranged between an end wall beam and a ladder of the transport container.

[0029] The support can typically be dimensioned so that its diameter is less than two decimeters. In particular, it can be designed so that it protrudes no more from the front of the transport container than a ladder positioned there. A support positioned in this way has the advantage of not protruding from the surface of the roll-off container, at least not from the front, thus not increasing the space required for the container.

[0030] The arrangement of the supports on the roll-off container is advantageously designed to ensure their permanent attachment. Accordingly, the supports can be welded to the end wall beam or attached to it using robust fasteners. In one embodiment, the supports can be secured to the end wall beams with multiple bolted connections, for example, four or more M18 bolts.

[0031] In an advantageous embodiment, the end wall beams have a profile with a recess in an elongated extension, for example a U- or H-profile, into which the supports engage, in particular in a form-fitting manner.

[0032] Since roll-off containers are usually supported on wheels on one side, there is an inherent risk that they may begin to move in one direction, for example, due to an impact from construction equipment or because of an inclined surface. In particular, if the container moves sideways, there is a risk that supports located on the end wall may buckle or twist backwards in the direction of movement.

[0033] Advantageously, by arranging the support in an elongated recess of a profile of the end wall support, for example in the recesses provided by a U- or an H-profile, buckling or twisting of the support can be prevented, since the support in the profile also receives a counter-support in the event of a torque rotating away from the roll-off container due to the profile at least partially enclosing the support.

[0034] This type of design reduces the risk of accidents and offers greater safety.

[0035] Furthermore, it is advantageous for the roll-off container with supports to be designed such that the supports do not project forward towards a roll-off tipper truck beyond a front side of the end wall beams, and / or do not project laterally beyond an outer side of the transport container. Such a support arrangement has the advantage that the supports do not protrude from the surface of the roll-off container, either frontally or laterally, thus generally maintaining compatibility with the requirements of a roll-off tipper truck. The support arrangement on the roll-off container can also be advantageously designed to meet the requirements of DIN 30722.

[0036] In an advantageous embodiment, the supports have a shaped piece, a shaped piece connected with a spacer, or a spacer shaped piece in one piece, which is formed into a recess of an end wall support for receiving, in particular positive-locking, reception.

[0037] Such a fitting can advantageously engage in a recess of a profile in the end wall support. This allows, particularly in conjunction with a spacer, a certain distance between the support and the end wall support to be achieved. This distance may be necessary to position the support beyond the underside of the support frame and / or to allow for interoperability with the skip of a roll-off tipper truck.

[0038] The fitting, the fitting connected with a spacer, or the spacer fitting advantageously has a comparatively robust, high-torque-absorbing connection with the vertical components of the support, which bear a load of the roll-off container in the vertical direction, for example a telescopic arrangement consisting of a support sleeve with a support rod guided in this sleeve in a form-fitting manner.

[0039] Advantageous is the fitting, the fitting connected with a spacer, or the spacer fitting welded to the components of the support that bear the load in the vertical direction, wherein the weld seam has a vertical extent of at least one decimeter, advantageously one and a half or more decimeters.

[0040] Advantageously, the support can have a sleeve, particularly one with a round, rectangular, or square shape on the inside, within which a support rod is arranged that is slidably connected within the sleeve in a form-fitting manner, or, particularly in the case of a round sleeve, rotatable via a thread. A rectangular outer profile of the sleeve, in particular, has the advantage of being able to be connected to an end wall beam in a form-fitting manner over its entire surface, possibly also on several sides.

[0041] Furthermore, a support, in particular a support rod of the support, can advantageously have a foot, a roller, or, interchangeably, a foot or a roller. Advantageously, a foot can be connected to a lower end of the support rod via a joint, in particular a ball joint.

[0042] A roll-off container with supports which have rollers at their lower ends, in particular swivel casters rotatable around a vertical axis, offers the advantage of being maneuverable with comparatively little effort, especially without the roll-off tipper vehicle, in conjunction with the rollers that are always present due to the design.

[0043] Advantageously, the roll-off container can be equipped with supports featuring an interchangeable support rod. This offers the benefit of easy maintenance of the supports, or, for example, if the roll-off container is used for varying purposes, the option of using a support rod with wheels or a foot.

[0044] Furthermore, the invention relates to a length-variable support designed to form a roll-off container with supports in the manner described above. Advantageously, the length-variable support can have one or more features of the supports of the arrangement described above.

[0045] In an advantageous embodiment of a length-variable support, which is designed to form a roll-off container with supports, this support has a molded part, a molded part connected with a spacer, or a spacer molded part in one piece, which is molded, in particular molded in a form-fitting manner, and is inserted into a recess in the profile of an end wall support and permanently connected to it.

[0046] A length-adjustable support with this combination of features offers the advantage of being interoperable with a wide variety of roll-off containers, even from different manufacturers. Therefore, it can often be retrofitted to existing roll-off containers. Drawings

[0047] The invention is explained in more detail below with reference to the attached schematic drawings and preferred embodiments.

[0048] They show Fig. 1 a schematic representation of a view of the front face of an embodiment of a roll-off container with supports; Fig. 2 a partial view of a schematic representation of an embodiment of a roll-off container with extended supports from a side perspective; Fig. 3 a schematic representation of an embodiment of a length-variable support, arranged on an end wall support of a roll-off container; Fig. 4 A schematic representation of the embodiment of a length-variable support on an end wall beam of a roll-off container in top view.

[0049] Out of Fig. Figure 1 shows the front face of a roll-off container 1 with supports 2, in particular for transport by a roll-off tipper vehicle with hook attachment, wherein the roll-off container 1 has a support frame with two longitudinal beams 6 and two end wall beams 7, which support a transport container 3 with the basic shape of a cuboid or parallelepiped or spat, which is arranged with one end face on the end wall beams 7.

[0050] Between the end wall beams 7, a receptacle 4, in particular a bracket, for engaging a hook, in particular a hook of a roll-off tipper vehicle, is arranged, and on the opposite end face in the area of ​​a lower edge of the roll-off container 1, two rollers 5 are arranged, which project downwards by a roller spacing d beyond an underside of the transport container 3 with support frame, specifically its longitudinal beams 6. The end wall beams 7 are oriented vertically and parallel to each other.

[0051] Furthermore, the roll-off container 1 has two length-adjustable supports 2, which are arranged on the end wall supports 7 and parallel to them and can be adjusted parallel to them and downwards by at least the roller distance d below the underside of the transport container 3 and support frame, here the longitudinal beam 6.

[0052] The supports 2 of the arrangement consisting of a roll-off container 1 with supports 2 are each arranged on a side of an end wall beam 7 that is parallel to the longitudinal side and facing outwards, i.e. from the perspective of the roll-off container 1 in a direction outwards and perpendicular to a longitudinal axis of the roll-off container 1.

[0053] Fig. Figure 2 shows a partial view of the embodiment of a roll-off container 1 with extended supports 2 from a side perspective, from which it can be seen that the end wall supports 7 have a profile with a recess in an elongated extension, in this case an H-profile, and the supports 2 engage in a recess of the profile, in particular positively interlocking with a shaped piece 8.

[0054] From a plurality of possible length settings, the supports 2 have a length setting in which the supports 2 extend by the roller spacing d plus a distance of at least 2%, in the illustration of about 6%, a length of the roll-off container 1 below the underside of the support frame or its longitudinal beam 6.

[0055] Furthermore from Fig. 2 and in detail from Fig. As can be seen, the supports 2 have a handle 10 for manual adjustment and a locking lever 9 for locking a length setting.

[0056] Apart from the locking lever 9 and the handle 10, the supports 2 do not extend forward towards a roll-off tipper vehicle beyond a front side of the end wall beams 7.

[0057] The support 2 has an internally square-shaped sleeve 17, within which a support rod 16 is arranged that is slidably locked in place. A foot 13 is arranged on the support rod 16, which can also be designed as a ball-head foot or replaced by a roller.

[0058] The handle 10 is arranged on the support rod 16 and, in addition to its function for manually adjusting the support rod 16, has a stop function in conjunction with the sleeve 17. The handle 10 can be detachably attached to the support rod 16 to allow for replacement of the support rod 16.

[0059] Furthermore from Fig. As can be seen in Figure 3, the shaped piece 8 has an outer surface 12 on its side, which is arranged parallel to an inner surface 11 of the end wall support 7. The end wall support 7 with H-profile has, as indicated by the letter H, a horizontal center support between two vertical side supports, which form four legs with respect to the center support. As shown in Figure 3, the shaped piece 8 has an outer surface 12 on its side, which is arranged parallel to an inner surface 11 of the end wall support 7. The end wall support 7 with H-profile has, corresponding to the letter H, a horizontal center support between two vertical side supports, which form four legs with respect to the center support. Fig. 3 The shaped piece 8 is shown to be flat, with a base surface, on the central support of the H-profile and with its outer surfaces parallel and centrally located to the inner surfaces 11 between two legs.

[0060] Out of Fig. As can be seen in Figure 4, the fitting 8 is connected to a spacer 18 and arranged on the sleeve 17, whereby the fitting 8 and spacer 18 can also be designed as a single piece spacer fitting.

[0061] The spacer 18 is permanently connected to the sleeve 17 of the support 2, in particular by means of a weld, and the fitting 8 is positively inserted into a recess of the end wall support 7. The fitting 8 is positioned centrally between the inner surfaces 11 of the legs of the end wall support 7. Any remaining gap between the outer surface 12 of the fitting 8 and the inner surfaces 11 of the legs of the end wall support 7 is limited to the radius of a fillet weld without impairing the positive fit. The connection of the fitting 8 to the end wall support 7 is effected by four spaced-apart bolts. As shown in Fig. 3. The distance between the upper and lower screw bolts exceeds the profile width of the end wall support 7.

[0062] Furthermore from Fig.As can be seen, the support rod 16 has holes 15 through which a pin 14, which can be actuated by the locking lever 9, can be passed to lock the support rod 16 in the sleeve 17. QUOTES INCLUDED IN THE DESCRIPTION
