Description

Device for the height transport of palletless packaging units for plate-shaped building materials

The invention relates to a device for the height transport of palletless packaging units for plate-shaped building materials, in particular insulation boards, preferably made of mineral fibers, for example for covering flat or flat-pitched roofs.

For the insulation of flat and gently sloping roofs, for example gently sloping roof shells made of trapezoidal sheets, concrete elements or concrete ceilings, large-format insulation boards, in particular made of rock wool, are used. These insulation boards are available in standard formats of 2 m length, 0.6 or 1, 2 m width and with material thicknesses between 7 and 16 cm. In addition, such insulation boards are known whose material thickness is between 3 and 6 cm, with thinner insulation boards of this type being used, for example, as so-called renovation boards that are placed on existing insulation layers. Such thinner insulating boards have a higher bulk density than the thicker insulating boards, which lead to improvements, i.e. leads to higher strength properties.

If the load-bearing roof shell consists of profiled sheets, the insulation panels are laid out transversely to the profile direction of the profiled sheets in order to form a resistant multi-span girder. The large format design of these insulation boards reduces the number of open joints and thus the proportion of possible thermal bridges. On the other hand, the proportion of the panel sections projecting over the lower flanges of the profiled sheets decreases, which ultimately significantly reduces the risk of breakage of the insulation panels, so that the effectiveness of the insulation layer is significantly improved.

The insulation panels in question are usually stacked on wooden pallets and handled with conventional handling equipment such as forklifts, cranes, pallet trucks or the like. The insulation boards are joined together with the wooden pallet to form a stable unit, in particular using a foil covering or tensioning straps. Due to the rigid wooden pallet, the above-mentioned machines can be used for the height transport of the transport unit made of wooden pallets and insulation boards. The disadvantage of wooden pallets is that they accumulate as waste on construction sites and must be disposed of together with the foil wrappings. In principle, it is possible to use reusable plates, but the costs of returning these pallets are very high, so that they have to be avoided in order to be able to offer a competitive product.

In addition, there is the disadvantage of the wooden pallets that the transport units have to be lifted onto the roof surfaces, particularly when covering flat and gently sloping roofs, and the wooden pallets have to be disposed of there after the insulation panels have been removed. Collection containers have proven to be particularly suitable for this, but they require the pallets to be stacked properly in order to optimize their filling. The provision of the collecting containers and the transport of the wooden pallets to the recycling companies as well as the recycling itself leads to additional costs.

A palletless transport unit is known from DE 42 18 354 C1. With this transport unit, the stack of insulation boards rests on two supports made of insulation board sections. The supports preferably consist of the same insulation panels which are also arranged in the stack. As a result, the length of the supports is designed according to the width of the insulation panels. In addition, the geometrical dimensions of the supports can be designed in such a way that they can absorb the weight of the load-bearing insulation panels without damage. The supports can be installed at a corresponding point in the insulation layer to be created at a later point in time, namely when all the insulation boards of the load-bearing stack have been processed, for example as a bead filler or as an abutment for film webs. With such transport units, the usual stack height is approx. 1 up to approx. 1.2 m has been found to be advantageous, so that a stack of insulation boards comprises approx. 2.4 to 2.9 m ^{3 of} insulation material and weighs between approx. 330 and 420 kg.

The results summarized in this transport unit insulating boards have a relatively high rigidity and are also sufficiently hard to obtain a sufficient inner stiffness of the entire stack together with the high friction coefficient of the surfaces of the insulating ^plates'. If the insulation panels are only 600 mm wide, it can be provided that two panels are arranged side by side in each stacking level. Sufficient stability of the stack is achieved even with such an arrangement of the insulation boards. In order to increase the stability of such a stack of insulation boards, it can nevertheless additionally be provided to arrange strips of tensile cardboard or film between the individual layers of insulation board, so that a gaping of the two stack halves along the longitudinal joint is prevented or reduced. The strips of film are guided up to the outer surfaces of the stack and gripped by a film or sleeve surrounding the stack in order to ensure the necessary cohesion of the transport unit.

> <The stacks of insulating material plates and the supports are connected to one another by at least one, preferably transverse to the longitudinal axis of the stack, and consequently vertically running bands made of, for example, polyolefin film, in particular a stretch film. The banderole is made from individual film webs, which at least consist of several layers at the points with higher mechanical loads. With the help of this banderole, the film intermediate layers guided on the outer surfaces of the insulation boards are pressed on, so that they increase the cohesion of a stack consisting of narrower insulation boards.

The plate arranged at the lowest point in the stack can alternatively or additionally be connected to the supports with the aid of a film or the like. Designed in this way, the lowest insulation board with the two supports replaces a pallet, but here has the advantage that it can be removed after removing the foils Insulation material can be used. The stack of insulation boards is then arranged on a pallet of insulation board and supports designed in this way and surrounded vertically with a band.

In addition to the attachment of the supports by means of a film to the lowest insulation board, it is also known to glue the supports to the lowest insulation board of the stack. Here it is disadvantageous that the assembled! Parts on the construction site must be separated from one another in order to incorporate the lowest insulation board or the supports as intended in the area of the insulation layer to be executed. Such a procedure is time-consuming and generally leads to damage to the components that are subsequently to be processed, namely insulation board and support, so that a perfect work cannot be created with these elements.

In addition to vertically wound banderoles, horizontally wound banderoles are also known. With this banderole arrangement, however, a large number of layers are necessary in order to produce a composite of the insulation boards that is resistant to deformation. In addition, the supports must also be reliably detected here, which is particularly difficult in the case of horizontally arranged banderoles if the length of the supports is less than the width of the supporting insulation boards.

The stacks of these insulating boards and the banderoles, including possible intermediate layers, represent a safe transport unit, despite the low use of material, which as a rule can also be handled with conventional machines for height transport, for example lift trucks. The resulting deformations of the insulation boards do not necessarily lead to damage or destruction of the insulation boards. Nevertheless, it can be observed that if these transport units are not handled properly, the insulation boards will be damaged and destroyed, making it impossible to create a proper work in the area of the insulation layer. For example, the 10 cm wide and also fork-shaped forks regularly damage the lowest insulation board when the fork is not completely lowered. Basically, the use of special fork shoes with a wide support surface is therefore an advantage, which, in addition to this damage, also significantly reduces deformation of the insulation panels.

The transport units described above are usually transported on trucks with open platforms from the manufacturer's plant directly to construction sites. These transport units are usually arranged with their longitudinal directions parallel to the longitudinal direction of the truck and in two planes one above the other. The arrangement of two transport units next to each other usually uses the full width of the truck. Lashing straps are used to secure the load. After the truck arrives at the construction site, the transport units are lifted up using the machines for height transport available on the construction site and, if necessary, transported directly to the roof area. Usually, cranes are used for this purpose, on the crane hook of which load suspension elements, for example belts or ropes, are attached, which are looped around the transport unit. In such a handling, in which the load-bearing elements are guided at an angle of, for example, 60 ° to the outer regions of the lowermost insulation board, the insulation boards are subjected to a great deal of bending and pressure transversely to their longitudinal axes. The load-bearing elements used here are designed, for example, as ring-shaped belts made of textile fabrics, which consist of highly tear-resistant yarns and are only approx. 8 to 12 cm wide despite high permissible load capacities, so that these belts, when used appropriately, lead to high surface loads on the insulation boards , When lifting the transport unit, the belts cut deep into the corner areas of the lowest insulation board and, depending on the length of the belt loop, also into the uppermost insulation boards. This prevents the belts from slipping and thus improves transport safety, but at least two insulation panels of the transport unit are regularly damaged to a greater or lesser extent. This results at least in the loss of a complete insulation board. Such a damaged insulation board can be made ready for use by trimming the damaged areas, but this represents a great deal of work that cannot be carried out during normal construction progress. As a result, it is preferred to install correspondingly defective insulation boards and consequently to build a defective plant.

A device for the height transport of packaging units for pallet-shaped building materials, in particular insulation boards, is known for example from DE 297 00 439 U1. This device consists of four articulated frame elements, of which two outer elements are placed vertically on a plate stack and two are placed on the plate stack between the outer elements. At the free ends of the elements to be arranged vertically, U-shaped projections are provided, which engage in free spaces of a pallet arranged below the plate stack.

This device, which is heavy in weight, can only be used in conjunction with pallets, load-bearing elements, in particular ropes or chains, being additionally required to arrange the device on a crane hook.

In addition, DE 197 00 787 A1 discloses another device in which a multiplicity of insulation boards are arranged on a U-shaped support element, which support element accordingly has two legs and a web connecting the legs, the legs being oriented at right angles to the web are and have holes for the arrangement of load-bearing elements, such as ropes. However, this known device is not suitable for the height transport of palletless packaging units. At most, it is used to hang a corresponding stack of insulation boards on the outside of a scaffolding. This device lacks the required stability for height transport.

On the basis of this prior art, the object of the invention is to design a generic device in such a way that it can be used to transport palletless packaging units safely and easily without damaging or destroying the insulating boards to be transported. The solution to this problem provides in a generic device that it is formed from at least two cross members and at least one load-bearing element that can be attached to both cross members, for example a belt, a rope or a chain, which can be attached to a hook of a crane or the like , the cross members each have at least one support surface and a stop surface arranged essentially at right angles thereto, which support surfaces can be brought into contact with a large surface at a distance from one another and which stops can be brought into contact with opposite side surfaces, preferably the side surfaces running at right angles to the longitudinal axis direction of the packaging unit is.

An alternative solution to the problem in a device according to the invention is that it is formed from at least one cross member and at least one load-bearing element that can be attached to the cross member, for example a belt, a rope or a chain, which is attached to a hook of a crane or the like can be attached, the traverse at least one support surface, which support surface can be brought into contact with a large surface in the area between two support bodies of the packaging unit.

A device according to the invention has the advantage that the traverses with the contact surfaces and the stop surfaces result in a uniform pressure load on the contact areas of the device. At the same time, the load-bearing elements in the area of the system on the lowest insulation board are spread in such a way that compressive forces on the narrow sides of the insulation boards are avoided, in particular in the area of the lowest insulation board above the supports. Bending stresses around the longitudinal axis of the insulation panels are also excluded.

The crossbeams are preferably formed from a hollow box section. Such a configuration has the advantage that a hollow box section has sufficient bending stiffness with low weight. Alternatively, it can be provided that the traverses consist of several profiles that are connected to one another connected, preferably welded. Also designed in this way, a high bending stiffness of the crossbeams can be achieved with low weight.

According to a further feature of the invention, it is provided that the abutment surfaces extend over the entire length of the crossbeams, so that the crossbeams lie completely against one side surface of the insulation board.

The stop surface, which can also consist of several shorter sections, is used in particular to prevent the crossbar from being pushed too far under the stack of insulation boards, so that an optimal lifting of the transport unit is ensured. At the same time, this also makes the handling of the transport or packaging unit safer, since it prevents the transport or packaging unit from falling out of the device, provided that the traverses are positioned precisely at the end regions of the lowermost insulation board and are not in different positions. which can lead to an unstable balance of the packaging unit to be lifted in the device. A symmetrical arrangement of the trusses ensures safe handling. The stop surface can also be designed to be foldable in order to simplify the transport of the cross members, in particular in the area of trucks. A foldable stop surface has the advantage that the volume used when transporting the trusses can be significantly reduced.

Rotatable elements made of flat steel, for example, are preferably attached to the two side boundaries of the crossbeams, on which an elongated eyelet for the passage of the belts, ropes or chains is welded. The load-bearing element can thus be pivoted, in particular rotatably, to the crossmembers at least about the longitudinal axis of the crossmembers. Provision is preferably made for the pivot point or pivot point of the load-bearing element on the cross member to be arranged above and preferably away from the stop on the cross member, so that twisting of the cross member during the lifting of the packaging and / or transport unit is avoided. The eyelet is designed in particular as a straight or curved elongated hole. According to a further feature of the invention, it is provided that the crossmember has at least one, preferably two, rotatably mounted rollers at the ends in order to facilitate the arrangement of the crossmember below the lowermost insulation board. The traverse can be moved on the loading area of the truck via the rollers. It is therefore not necessary to lift the possibly heavy traverse. This configuration serves in particular to make work easier with the device according to the invention.

The cross member is preferably formed in two parts and has a first part with the support surface and the stop surface and a second part designed as a chassis. Both parts are preferably pivotally connected to one another. The crossbeam can be moved in a simple manner on the loading surface of the truck or in the area of a flat floor, for example a warehouse, by the chassis. The part with the support surface and the stop surface arranged pivotably on this chassis has the advantage that, due to the pivotable design, this first part of the crossbar adapts in a simple manner to the conditions of the packaging and / or transport unit to be handled.

A further development of this embodiment provides that the chassis is arranged offset from the first part in such a way that the chassis protrudes from the first part on at least one edge, in particular the edge with the stop surface. In this way, the chassis can still be easily handled with the foot when the first part has already been pushed almost completely under the lowest insulation board of the panel stack.

It is further provided in this embodiment that the chassis has at least one, preferably at least two rollers, which are rotatably mounted on a rail or plate-shaped support element. In addition to this configuration, it can be provided that a pivot axis is arranged between the first part and the chassis, in which one preferably laterally protruding shaft which is used to receive the load-bearing element. This enables a compact design without additional stop elements.

According to a further feature of the invention, it is provided that the shaft has stop elements on both sides, in particular plates with a diameter that is larger than the diameter of the shaft, the plates preferably being round or elliptical. These stop elements prevent the load-bearing elements from slipping, for example when a crane lifting the device rotates.

The plates can be fixed or releasably arranged on the shaft, a releasable fastening of the plates to the shaft opening up the possibility of also plugging tight loops, the diameter of which is smaller than the diameter of the plates onto the shaft and then the loop with the plate secure against slipping.

For reasons of weight, it may be advantageous to have the shaft from two stub axles

.4, whereby a correspondingly stable construction with the required strength values is then necessary.

According to a further feature of the invention, it is provided that the two traverses to be arranged on the packaging unit can be connected via at least one connecting element, in particular a chain, a belt, a rope or the like. This embodiment has the advantage that slipping of the two cross members or at least one cross member is prevented by tensioning the two cross members parallel to the longitudinal extension of the plates. This configuration also serves occupational safety with the traverse according to the invention.

It is preferably provided that a third traverse is provided between the two traverses to be arranged on the outside of the packaging unit, which is to be arranged between two support bodies of the packaging unit. This third traverse can also be used alone, ie without the two on the outside trusses are used to lift a packaging unit with a crane.

For this purpose, the third traverse is inserted between the two support bodies of the packaging unit.

The third crossmember preferably has a support surface, the width of which corresponds approximately to the distance between the support bodies of the packaging unit or is designed to be correspondingly adjustable. The advantage of such a traverse is that it makes optimal use of the space between the two supports to lift the packaging unit. As a result, bending stresses on the lowermost insulation board in particular are avoided. In conjunction with two cross beams arranged on the outside, there is also a further reduction in the bending stresses of the insulation panels.

According to a further feature, the third traverse has at least two pegs on both sides for the attachment of a load-bearing element.

Furthermore, it is provided that the third cross-member has a chassis with at least one roller or one wheel so that the cross-member can be arranged under the packaging unit in a simple manner even without lifting. The axis of the roller or wheel is preferably aligned at right angles to the longitudinal axis of the pins, so that the crossmember can be moved at right angles to the longitudinal extent and parallel to the support bodies.

It is provided according to a further feature of the invention that the pins have stop elements at their ends, in particular plates with a diameter that is larger than the diameter of the pins. These stop elements also have the advantages already described above, to which reference is made. The stop elements are particularly round or elliptical in order to reduce the risk of injury when handling the crossmember by reducing sharp edges.

The third cross member is preferably connected to the two outer cross members via at least one connecting element. Such a connecting element can be, for example, a chain, a rod or a rope, which connecting element fixes the relative position of the cross members to one another.

According to a further feature of the invention, it is provided that spreading elements are arranged above the packaging unit and parallel to the crossbeams between sections of the load-bearing element. These expansion elements keep the sections of the load-bearing element at a distance, so that even the upper insulation panels of the packaging unit are not impermissibly subjected to a compressive stress running at right angles to the longitudinal extent of the insulation panels.

The spreading elements are preferably variable in length and designed to be pressure-resistant, so that they can be adapted to different widths of insulating material elements or packaging units.

The expansion elements are preferably formed from profile elements, in particular with a flat rectangular cross section, in order to reduce their weight while at the same time being strong.

According to a further feature of the invention, it is provided that the expansion elements have one or more rollers or roller sections that can be placed on the packaging unit. The arrangement of such rollers or roller sections makes it possible to move the expansion elements on the packaging unit in a simple manner even with a high weight, without thereby damaging or destroying, for example, the film packaging or the top insulation board. Stop elements are preferably arranged above the spreading elements, which serve to guide the load-bearing element and fix the spreading elements in their position relative to the packaging unit. With this configuration, the spreading elements can be positioned precisely within the load-bearing elements, so that an inclination of the spreading elements relative to the uppermost insulation board of the packaging unit is avoided.

According to a further feature of the invention, it is provided that the stop elements consist of a preferably U-shaped or closed frame and at least two deflection rollers, the load-bearing element being able to be guided between the deflection rollers. The deflection rollers have the advantage, on the one hand, that adjustment of the stop elements relative to the load-bearing elements is possible without problems when the load-bearing elements are unloaded, ^" while the tension elements are tensioned and fixed in the load-bearing elements when the load-bearing elements are tensioned.

To further develop a device according to the invention, it is also provided that the crossbars, shafts or pins are rounded at their ends or formed with grooves in order to prevent the load-bearing elements from slipping off the crossbars, shafts or pins.

Finally, according to a further feature of the invention, it is provided that the traverses, shafts or pins have guide elements at their ends for fastening the load-bearing element.

Further features and advantages of the invention result from the following description of the accompanying drawing, in which preferred embodiments of the invention are shown. The drawing shows:

According to the exemplary embodiment according to FIG. 1, the device for height transport of palletless packaging units 1 shown in FIG. 1 consists of two cross members 2 and two load-bearing elements 3 attached to the cross members 2, which are designed as belts and can be suspended in a crane hook 4. The packaging unit 1 has a large number of insulation boards 5, which are arranged as a stack on two support bodies 6. The packaging unit 1 also has connecting elements (not shown in more detail in FIG. 1) between the insulation boards 5 and the support bodies 6, for example in the form of film strips or film envelopes.

The cross members 2 each have a contact surface 7 and a stop surface 8 oriented at right angles to the contact surface 7. In the exemplary embodiment shown, each cross member 2 consists of two webs 9 and 10 welded together in a T-shape, the web 9 supporting the surface 7 and the web 10 has the stop surface 8. Rectangular plate elements 11 are welded to the ends of these T-shaped mutually arranged webs 9 and 10, which, in the case of a device arranged on the packaging unit 1, rest in the region of the longitudinally extending side surfaces of the lowermost insulation board 5.

Flat irons 12, each with an eyelet 13 arranged at the end, are pivotably attached to these plate elements 11 about a pivot point 14. The eyelet 13 is used to fasten the load-bearing element 3 to the crossbar 2. In this case, the flat iron 12 is fastened to the plate element 11 of the crossbar 2 above and away from the stop surface 8.

The handling of the device shown in FIG. 1 provides that the two cross members 2 with the load-bearing elements 3 are hooked into the crane hook 4. The traverses 2 are then pushed at oppositely arranged edge areas on both sides of the support body 6 under the lowermost insulation board 5 of the packaging unit 1, so that the surface 15 of the lowermost insulation board 5 facing the support bodies 6 with its edge areas arranged in the longitudinal direction on the support surfaces 7 of the Cross members 2 rest and at the same time the shorter side surfaces running transversely to the longitudinal direction of the insulation board 5 rest against the stop surfaces 8 of the cross members 2. The crossbeams 2 thus extend with their longitudinal direction parallel to the longitudinal direction of the support body 6. The packaging unit 1 can now be arranged in this way by the crane, which is not shown in detail can be lifted without excessive bending or compressive loads on the insulation panels 5 of the inside of the packaging unit 1

Packaging unit 1 are exercised. At the same time, the device according to FIG. 1 enables the packaging unit 1 to be lifted safely without the risk of the packaging unit 1 falling out.

A second embodiment of the invention is shown in Figure 2. The configuration of the crossbeams 2 according to FIG. 2 essentially corresponds to the configuration of the crossbeams 2 in FIG. 1. In addition, it can be seen that the web 10 is interrupted and consequently has two rectangular elements which are arranged at a distance from one another.

Furthermore, the traverses additionally have rollers 16 on their underside, which are rotatably mounted between webs 17 and the plate elements 11. The rollers 16 facilitate the use of the device in that the cross members 2 can be easily pushed under the lowest insulation board 5 of the packaging unit 1 even with a higher weight. A defined distance is also set by the rollers 16, which can prevent damage to the lowermost insulation board 5 by virtue of the traverse 2 resting on the contact surface and being able to be pushed in a simple manner under the lowermost insulation board 5 of the packaging unit 1, without into the side surface this insulation board 5 to be pressed.

It can also be seen in FIG. 2 that the flat irons 12 are cranked outwards in order to set a distance of the load-bearing elements 3 from the side surfaces of the insulation panels 5.

In addition, the device according to FIG. 2 has a spreading element 18 in the form of a roll for each load-bearing element 3, which is rigid against pressure, above the packaging unit 1. This role is rotatably mounted in stop elements 19 and can be adjusted in height relative to the packaging unit 1 within the load-bearing element 3 via the stop elements 19, the role of the expansion element 18 on the surface of the uppermost insulation board 5 Packing unit 1 rests. The stop element 19 is described in more detail below with reference to FIGS. 5 and 6.

FIGS. 3 and 4 show an alternative embodiment of a cross member 2. This alternative embodiment of the crossmember 2 has a first part 20 with the support surface 7 and the stop surface 8, which are arranged at right angles to one another. At its end opposite the stop surface 8, the first part 20 is angled at a right angle in order to avoid damage to the insulation board 5 due to a sharp edge formation when the cross member 2 is pushed under the bottom insulation board 5.

Arranged below the first part 20 of the crossmember 2 is a second part 21 of the crossmember, which has a chassis 36 consisting of roller bearings 22 and rollers 23 rotatably mounted therein. The first part 20 is connected to the second part 21 via a joint with a pivot axis 24 with limited pivoting movement. The pivot axis 24 is arranged eccentrically on the second part 21 and centrally on the first part 20, so that the first part 20 is offset from the second part 21 and the second part 21 with an edge 25, namely the stop surface 8 relative to the first part 20 protrudes. In the area of the edge 25 there is therefore the possibility of pushing the rollable cross-member 2 under the packaging unit 1 with the foot, while at the same time the hands of the person handling the spreading element 3, for example, spread such that they can be brought into lateral contact with the packaging unit 1 ,

In the area of the pivot axis 24, the cross member 2 has on both sides protruding shaft sections 26 which are designed as stub axles and which serve to stop the load-bearing element 3. At the end, the shaft sections 26 have stop elements in the form of plates 27, the diameter of which is enlarged compared to the diameter of the shaft sections 26. The plates 27 can be detachably attached to the shaft sections 26 and can have a circular or elliptical shape. FIGS. 5 and 6 show a section of an expansion element 18 which, according to FIG. 5, consists of a tube 28 and roller sections 29 rotatably mounted thereon. At the end of the tube 28, the stop element 19 is arranged, which consists of a plate 30 and a frame 31, the plate 30 being fixed to the tube 28 and the frame 31 being arranged at an obtuse angle to the plate 30.

The frame 31 consists of two laterally arranged plate elements 32 and connecting rods 33 which extend between the plate elements 32 and have a round cross section and which serve to guide the load-bearing element 3. For this purpose, the distance between the plate elements 32 is essentially designed according to the width of the load-bearing element 3 designed as a belt. This belt lies flat against the outside of the plate 30 and is guided over the connecting rod 3 arranged in the region of the end of the plate 30, in order then to be guided between the plate elements 32 into the region below the second connecting rod 3, from where the The belt then runs in the direction of the crane hook 4, not shown. Due to the friction on the connecting rods 3 in connection

• With the angular arrangement of the frame 31 relative to the plate 30, the spreading element 18 can be adjusted and held relative to the cross member 2 in accordance with the height of the packaging unit 1.

FIGS. 7 to 9 show a further embodiment of a cross member 2, this cross member 2 not being arranged corresponding to the cross members 2 according to FIGS. 1 to 4 on the outside of the support body 6 on the packaging unit 1, but between the support bodies 6 of the packaging unit 1.

This cross member 2 has a support surface 7, the width of which approximately corresponds to the distance between the support bodies 6 of the packaging unit 1. Alternatively, it can be provided that the width of the support surface 7 is variable, so that the crossmember 2 can be adapted to different packaging units 1 to different distances between the support bodies 6. The bearing surface 7 is in the area of a Cross section U-shaped sheet metal element 34 is arranged, which is folded on both sides to form webs 35. Arranged between the webs 35 on the underside of the sheet metal element 34 is a chassis 36, which consists of two parallel U-shaped profiles 37 and in each case two rollers 38 mounted therein. The profiles 37 are closed at the end with a plate 39, to which two pins 40 are welded, which serve to fasten the load-bearing element 3. The free ends of the pins 40 carry stop elements designed as plates 41, which are elliptical in the present exemplary embodiment. The plates 41 can be fixed or detachably connected to the pin 40 and have a larger diameter than the pin 40.

It can be seen that the longitudinal axes of the pins 40 are aligned at right angles to the axes of rotation of the rollers 38. Thus, the cross member 2 according to Figures 7 to 9 can be rolled transversely to the longitudinal axis of the insulation panels 5 or the packaging unit 1 between the support body 6 and then the load-bearing elements 3 can be attached to the pin 40 before the packaging unit 1 is then shown with a not shown Crane is raised. Of course, the cross member 2 according to FIGS. 7 to 9 can also be combined with the spreading elements 18 already described above. Furthermore, it is possible to combine the crossmember 2 according to FIGS. 7 to 9 with further crossmembers 2 according to FIGS. 1 to 4, it possibly proving to be advantageous to use the individual crossmembers 2 by means of chains, ropes or belts and by means of shear-resistant elements such as rods or plates to connect to each other to fix their position in relation to the packaging unit 1.

An alternative embodiment of the traverse 2 according to FIGS. 7 to 9 is shown in FIGS. 10 to 12. This embodiment according to FIGS. 10 to 12 differs from the embodiment of the cross member 2 according to FIGS. 7 to 9 in that, instead of the sheet metal element 34, the cross member has two round rods 42 arranged at a distance from one another, which ends in the pin 40. The two round bars 42 are connected to one another at a distance from one another via cross bars 43. These cross bars 43 can be divided according to FIG formed and rotatably mounted on the round rods 42 to reduce the transport dimensions of the cross member 2. In this case, the two sections of the crossbars 43 are beak-like at the ends, so that they can be positively connected to one another and form the crossbar 43 with sufficient shear rigidity.

The sections of the crossbar 43 which are designed in accordance with the outside diameter of the round rod 42 are plugged onto the round rods 42 and secured against being pressed out by a lower bolt which is spring-loaded.
