Description

Technical field

The present invention relates to a pallet for full-length material, in particular for conveying profiles, with a loading surface whose length is at least four times greater than its width, consisting of continuous longitudinal beams which are connected to one another by a plurality of transverse stiffeners.

BACKGROUND OF THE INVENTION

DE 4403743 discloses a pallet in Euro form in which longitudinal stiffeners are formed which are connected to each other by means of transverse stiffeners. In the middle, for the reinforcement of the transverse stiffeners, guide rails are provided which serve to catch the forks of the forklift. By means of bolted joints, the stiffeners connected to each other are covered with a continuous bottom plate to form the loading surface. At the end of the transverse stiffeners, protruding abutments are formed for at least two opposite sides of the deposited material. Although the pallets can be stacked on each other by means of free-standing supports, these pallets are generally not suitable for the shortened material, since the structure is not statically sufficient for such applications. For this reason, the supports are only set on the transverse reinforcements supporting the transverse direction, so that only limited horizontal forces can be transmitted for stability reasons. The longitudinal stiffeners are also provided with protruding peaks at the bottom, which can be damaged during rough operation on the construction site. The stacking guiding peaks are susceptible to damage and pose a risk of injury, so that friction-free centering is not always possible with this pallet concept.

Pallets 100 are also known in the art

- 2 ·············································· Such shortened material pallets 100 are generally 6 m long and are only lifted laterally with the forklift. The known uncut material pallet 100 has longitudinal members 101 which are connected to one another by a plurality of transverse beams 102. On the side, support columns 103 are attached to the longitudinal members 101, which form a steel frame with the upper beam 104. Support legs 105 are formed on the underside of the longitudinal members 101, in which a support 106 is formed. On the upper side of the upper beam 104 are vertical pins 108 that can be inserted into the support 106 in the support leg 105 so that known pallets 100 for shortened material stacked on each other.

Forks 107 are formed in the middle of the longitudinal members 101 into which the forks of the fork-lift truck can be inserted. This determines the exact position for the forklift. On the upper side of the upper beam 104, a yoke 109 is formed on which a crane crane (not shown) can be suspended. Such known unloaded pallets 100 have the advantage that expensive individual packs of profiles are eliminated.

However, in the case of the known shortened pallets 100 shown in FIG. 12, it is disadvantageous that the known shortened pallets 100 occupy a large space during return transport and empty storage, since only stacked ones can be transported. At most, two U-shaped pallets can be inserted into each other. When the upper beam 104 is damaged and deformed in contact with known pallet 100 for uncut material, the vertical pins 108 can deflect from their predetermined position so as to prevent stacking of known pallets 100 for unabridged material. In addition, the vertical pins 108 and the support legs 105 form mechanically weak spots of the known full-length pallet 100, which may be damaged. A further disadvantage is that, while the fork bands 107 occupy the forks.

- the fork position, but the loaded material is not supported unless the fork also grasps the opposite fork belt 107 completely. Here, due to the inclined position of the known shortened material pallet 100, the loaded material is damaged in the lower abutment region. The production of known pallets 100 for uncut material is also costly, since a plurality of profiles must be welded together.

SUMMARY OF THE INVENTION

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a pallet for an unabridged material of the aforementioned type which, with greater stability, allows safe handling in the empty state, with more pallets to occupy only a small space.

during transport, taking full-length material

This object is solved by a pallet for the uncut material with the features of claim 1.

When a plurality of columns extending substantially perpendicularly upwardly are spaced apart on the longitudinal beams of the shortened pallet on the outer sides, the shortened pallets can be stacked together in an empty state, whereupon the stacked shortened pallets are then placed one above the other in the longitudinal direction offset by the width of the column, or they are also stacked on top of each other, the upper pallet for the shortened material being placed on the columns of the lower pallet for the shortened material. The ladder-like construction of the pallet for the shortened material ensures high stability, so that typical high loads can also be transmitted to the pallets for the shortened material.

According to a preferred embodiment, the longitudinal beams form, with their underside, a bearing surface for laying • 4

- 44444444 pallets for uncut material. Thereby the support legs, which can be easily damaged if the material is short.

there is no need to create a pallet handling for

For particularly good pallet stability for the shortened material and low deflection of the longitudinal beams, these longitudinal beams are formed rectangular, with columns of comparable height being placed on the longitudinally projecting sides, so that horizontal loading is applied.

As a result, the columns can be set in position and can be easily moved to the sides

To create a common loading surface, transverse stiffeners are attached to the upper side of the longitudinal beams. There are no steps at the transition between the transverse stiffeners which can cause damage to the material being transported.

According to a further embodiment of the invention, the longitudinal beams in the central region are provided with two outwardly open rectangular profiles which are arranged in the recess of the longitudinal beams. The forks of the forklift can be inserted into these rectangular profiles, the closed shape of the rectangular profile preventing the material from being damaged from below. Also, if the forks are not inserted over the entire width of the uncut material pallet, this will prevent the misaligned pallet position.

Preferably, the columns are open at the bottom and are provided on their upper side with a projection which is inserted into the column of the upper pallet for the uncut material. As a result, when stacking the pallets for the shortened material, a centering can be achieved which prevents lateral movements after folding the pallets for the shortened material.

- 5 dlouhé to allow long objects to be transported by the uncut material pallet, preferably an extension device is provided on at least one front side of the uncut material pallet. The extension device comprises two side profiles for insertion into the longitudinally open longitudinal beams, so that the extension device is adjustable on the pallet for the uncut material by means of clamping or friction forces or locking elements. According to a further embodiment of the invention, the columns are rotatably mounted on the longitudinal beams above the support cot. This allows them to be positioned substantially parallel to the longitudinal beams, so that the pallets for the uncut material occupy only a minimum volume when empty.

Pallets for unabridged material also have pins on the outside of the longitudinal beams for attaching the crane hitch. These pins do not protrude over the laterally positioned columns and are thus protected.
