Description

The present invention relates to a long goods pallet, in particular for the transport of profiles, with a loading surface whose length is at least four times as large as the width thereof, wherein continuous longitudinal members are provided which are interconnected via a plurality of cross members.

From DE 4403743 a pallet, in the form of a Euro-pallet is known, in which a plurality of longitudinal struts are provided, which are interconnected via transverse struts. In the middle, guide rails are provided for reinforcing the transverse struts, which serve to receive the fork of a forklift. The interconnected via screw struts are covered to form a cargo area with a continuous bottom plate. At the end of the cross struts protruding supports are arranged, which provide the stored goods at least on two opposite sides of a support. Although the pallets can be stacked in one another by the freestanding supports, but these pallets are not suitable for long goods, since the structure for static use is not sufficient for such applications. For this purpose, on the one hand, the supports are fixed only on the transverse struts supporting in the transverse direction, so that only limited horizontal forces can be absorbed for stability reasons. Furthermore, the longitudinal struts are provided downwards with protruding tips that can be damaged during rough operation of a construction site. The provided for stacking guide tips are also against Damage prone and also represent a special risk of accidents, so that the smooth centering in this pallet design can not always be guaranteed.

Furthermore, so-called long pallets are also known in the prior art, as shown in Fig. 12. Such long pallets usually have a length of about 6 m and are therefore only laterally lifted by a forklift. The previously known long goods pallet 100 comprises longitudinal members 101, which are connected to one another via a plurality of cross members 102. On the side of each post 103 are connected to the side rails 101, which form a frame 104 made of steel on a rail 104. On the underside of the side members 101 support feet 105 are provided, in each of which a receptacle 106 is arranged. At the top of the rail 104 pins 108 are mounted, which can be inserted into the receptacle 106 of a support foot 105, so that the long goods pallets 100 can be stacked on each other.

On the side member 101 are provided in the middle tabs 107, in which a fork of a forklift can be inserted. As a result, the exact position for the forklift is specified. Further, the rail 104 109 are formed on the upper side of the rail, in which a not shown crane harness can be hung. Such long pallets have the advantage that expensive individual packaging accounts for profiles.

A disadvantage of the long goods pallet shown in FIG. 12, however, is that this long goods pallet occupies a large volume of space during the empty return transport and in the empty storage since it can only be transported in a stacked manner. If necessary, two pallets can be pushed into each other in a U-shape. If the top rail is damaged and deformed when handling the long goods pallet 100, the bolts 108 can be removed from their desired position, so that stacking of the long goods pallets 100 is prevented. The bolts 108 and the feet 105 also form mechanical weak points of Langgutpalette that comparatively easy can be damaged. Another disadvantage is that although the tabs 107 provide the fork position, the contents will not be protected if the stacking fork does not fully engage the opposite tab. Here occur then by misalignment of Langgutpalette 100 damage to the contents in the lower support area. Finally, the production of the known long pallets 100 is complicated, since a large number of profiles must be welded together.

DE 199 31 248 shows a pallet for receiving a two-wheeler, wherein in each case a frame-shaped bracket is provided at a front and a rear end face, which is formed from vertical supports and a cross member. If necessary, this bracket can also be pivoted onto the loading area for stacking several pallets. By the frontally arranged bracket loading the pallet with long goods is poorly possible because the range is customized for a two-wheeler.

From the CH 688 474 a long goods pallet is known which has longitudinal struts, which are interconnected via a plurality of cross struts. At the longitudinal struts upstanding uprights are arranged at the top. As a result, the long goods pallet is indeed suitable for transporting extruded profiles, but in the empty state, the long pallets shown can be poorly stacked. For a space-saving transport formed as plug-in posts from the longitudinal struts would have to be dismantled, which is relatively expensive.

It is therefore an object of the present invention to provide a generic Langgutpalette of the aforementioned type, which allows for high stability, safe handling during transport, which should occupy only a small volume of space in the empty state several Langgutpaletten.

This object is achieved with a long goods pallet with the features of claim 1.

If a plurality of spaced apart posts are attached to the side rails of the long goods pallet at the respective outwardly facing sides, which are substantially vertically upwards, the Langgutpaletten can be stacked together in the empty state, in which case the stacked Langgutpaletten in the longitudinal direction by the width of a Post staggered are arranged or stacked on each other when the upper Langgutpalette is placed on the post of the lower Langgutpalette. The ladder-like structure of the long goods pallet ensures high stability, so that the high loads typical of long goods pallets can also be accommodated.

According to a preferred embodiment of the invention, the longitudinal members form with their underside a support surface for parking the Langgutpalette. This eliminates the need for the provision of support legs, which can be easily damaged when dealing with the long goods pallet.

For a particularly good stability of the long goods pallet and only a small deflection of the longitudinal members, these are formed in cross-section substantially rectangular, wherein the posts are attached to the longer upstanding sides. As a result, the posts can be set over a comparatively large height, so that lateral horizontal loads can be well absorbed.

To form a common loading area, the transverse struts preferably terminate flush with the upper side of the longitudinal members. As a result, no steps are created at the transition between the transverse struts and the longitudinal members, which could cause damage to the load.

According to a further embodiment of the invention, the longitudinal members are connected in the middle region with two outwardly open rectangular tubes, which are fixed in a recess of the longitudinal members. In these rectangular tubes, the stacking forks of a forklift can be inserted, the closed shape of the rectangular tubes prevents the load from being damaged from below. Even if the stacking fork is not inserted over the entire width of the long goods pallet, thus an inclination of the long goods pallet is prevented.

Preferably, the posts are open at the bottom and provided on their upper side with a projection which can be inserted into the posts of an upper Langgutpalette. As a result, a centering can be achieved when stacking the long pallets on each other, which prevents lateral movement after stopping the Langgutpaletten each other.

In order to be able to transport longer items with the long goods pallet, a telescopically adjustable extension device is preferably provided at least on one end face of the long goods pallet. The extension device comprises two lateral profiles which can be inserted into the front side open longitudinal members, so that the extension device is held adjustable by clamping or friction forces or a locking device on the Langgutpalette.

According to the invention the posts are pivotally mounted on the longitudinal members via support shoes. This makes it possible to apply the support essentially parallel to the longitudinal members, so that the long pallets occupy only a minimal volume of space when empty.

Furthermore, the long pallets comprise on the outwardly directed sides of the side members bolts for fixing a crane harness. These bolts do not protrude beyond the side-mounted posts and are thus protected.

A long goods pallet 1 comprises two spaced-apart longitudinal members 2 made of a hollow steel profile, which are connected to one another via transverse struts 3. The side members 2 have a substantially rectangular cross-section, with the longer sides extending in the vertical direction. On a side wall 21 of the longitudinal member 2 a plurality of spaced apart posts 4 are attached.

An upper side 20 of the side members 2 terminates flush with a top side 30 of the transverse struts 3 in order to form a common loading area for long items. The longitudinal members 2 form with their underside 22 a support surface for parking the Langgutpalette 1, wherein the cross braces 3 have a lower height and thus do not rest on the ground.

In a central region, two rectangular tubes 5 are provided, which are fixed in a lower recess of the longitudinal members 2. The rectangular tubes 5 have on the opposite sides of an opening 6 for receiving a stacking fork of a forklift.

Further, on the outside 21 of the side members 2 bolts 7 are mounted, which can be brought into engagement with a crane harness. On an inner side 23 of the side members 2 tabs 8 are provided, can be set in the wall or frame elements. The long goods pallet 1 shown in FIG. 1 is formed symmetrically both to a plane in the middle of the two longitudinal members 2 and to a plane centrally and perpendicular to the longitudinal members 2.

As can be seen from FIGS. 2 and 3, an extension device 9 can be attached to the front side of the longitudinal members 2. The extension device comprises profiles 90, which can be inserted into the side members 2. The profiles 90 can be held by means of clamping or frictional forces. It is also possible to provide a separate latching device for fixing the extension device 9. The two profiles 90 are connected to one another via a transverse strut 91, to which a frame 92 is attached. The frame 92 may be foldable or removable, for example, to be fixed to the tabs 8. The frame 92 may be provided with a filling plate 93.

The extension device serves on the one hand to secure the long goods stored in the long goods pallet 1 in the longitudinal direction, on the one hand against automatic slippage during transport and on the other hand also to protect the long goods against frontal damage. In addition, it is possible by the telescopic adjustment to be able to record even over long cargo accordingly.

In Figs. 4A and 4B, a post 4 is shown in an enlarged view. A post 4 is fixed via a spacer element 49 on the longitudinal member 2, so that at a Stacking of the long goods pallets 1 for storage and transport game between posts 4 and adjacent longitudinal members 2 of the long pallets 1 is provided. The post 4 is welded to the spacer 49.

In the upper part, a projection 40 is provided on the post 4, which has the shape of a pyramid and is connected by welds 41 with the post 4. The projection 40 therefore includes inclined surfaces 42 which are insertable into a lower opening 43 of a further post 4 and thus a centering and alignment of two stacked posts 4 is made.

As can be seen from FIGS. 5A and 5B, the long goods pallets 1 are designed symmetrically to a center plane M. In this case, a distance Y between the center plane M and the rectangular tubes 5 is formed smaller than a distance X between the median plane M and the bolt 7. Further, the entire length of the long goods pallet 1 is substantially greater than the width of the long goods pallet, for example in a ratio of 6 to 1. In Fig. 6 several long pallets 1 can be seen in a stacked position. The posts 4 engage with their projections 40 in the openings 43 of a post arranged above it 4. In this position, the long pallets 1 can be filled one above the other stacked.

In Fig. 7 the same long goods pallets 1 are stacked for transport into one another, wherein two superposed long goods pallets 1 are arranged offset in the longitudinal direction by the width of a post 4 to each other. Thus, only a small load volume for the empty Langgutpaletten 1 is required.

A second exemplary embodiment of a long goods pallet 1 according to the invention is shown in FIGS. 8A to 8C. Identical components are identified by the same reference numerals.

In this embodiment, 2 supporting shoes 45 are provided on the longitudinal beams, on which the posts 4 are arranged pivotably and liftable in the vertical. The support shoes 45 have a bottom plate 46 which has a rectangular cut-out, which corresponds to the size of the hollow chamber of the post 4, so that the pyramid-like projection 40 of the post 4 can be inserted in stacking the long pallets 1 in the bottom plate 46. On the support foot 45, an axle 48 is further provided, which forms the pivot axis of the post 4. The post 4 in this case has a slot 50 which is penetrated by the axis 48. Through this slot 50, the post 4 can be raised and lowered, which serves to put a locking lug 51 on a locking pin 49 and thus to lock the erected position of the post 4. Furthermore, a stop 47 is still provided, which limits the rotational movement of the post 4 in the raised position. As can be seen in particular in Fig. 8A, the posts 4 can be locked in an erect position and in a position parallel to the side rails 2. For this purpose, 2 corresponding locking receptacles are attached to the side rail.

In Fig. 9, the long goods pallets 1 of Figs. 8A to 8C are shown in the stacked position. This position corresponds to that of FIG. 6. In FIG. 10, the long goods pallets 1 are stacked one above the other in a volume-reduced manner, for which purpose the posts 4 are applied to the side members 2 of the long pallets 1 via the aforementioned pivoting mechanisms.

In Fig. 11, a crane loading gear 70 is shown, which has four gripping arms 71 on a support beam 74, which are arranged at a distance of the bolts 7 on the longitudinal beams 2. At the ends of the gripping arms 71 hooks 73 are provided, which are all oriented in a longitudinal direction. These hooks 73 can be brought to the mushroom pins 7 on the longitudinal beams 2, so that the long goods pallet 1 can be received on the crane loading gear 70. The gripping arms 71 are arranged on holders 72 spaced from the support beam 74, wherein the distance corresponding to the distance of the mushroom pin 7 is provided. Through this crane loading harness 70 is a transport of the long goods pallet 1, in particular in the horizontal direction possible.
