Description

PALLET FOR UNLIMITED MATERIAL

Technical field

The present invention relates to a pallet for non-shortened material, in particular for conveying profiles, with a bearing surface whose length is at least four times greater than its width, which is formed by continuous longitudinal beams which are interconnected by a plurality of transverse reinforcements.

BACKGROUND OF THE INVENTION

DE 4 403 743 discloses a pallet in Euro form in which longitudinal reinforcements are formed which are connected to one another by means of transverse reinforcements. In the middle, guide rails are provided for the reinforcement of the transverse stiffeners, which serve to catch the forks of the forklift. The reinforcements connected to each other by means of screw connections are covered by a continuous bottom plate to form the bearing surface. At the end of the transverse stiffeners, protruding supports are provided for at least two opposite sides of the deposited material. Although the pallets can be stacked on one another by means of free-standing supports, these pallets are generally not suitable for uncut material, since the construction is not statically sufficient for such applications. Therefore, the supports are established on the one hand only in the transverse direction of the transverse reinforcements, so that only limited horizontal forces can be transmitted for reasons of stability. The longitudinal reinforcements are also provided with protruding peaks at the bottom, which may be damaged during rough operation on the construction site. The stacking guiding peaks are susceptible to damage and present a risk of injury, so that centering without friction is not always possible with this pallet concept.

Pallets 100 for unabridged material are also known in the art, as shown in FIG. Such known pallets 100 for unabridged material are generally 6 m long and are only lifted laterally by a forklift. The known shortened pallet 100 has longitudinal members 101,

934 / B r

The support beams 103 are attached to the side 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 the support 106 is formed. On the upper side of the upper beam 104 are vertical pins 108 which can be inserted into the support 106 in the support leg 105 so that pallets 100 for the uncut material can be known. stack on top of each other.

On the longitudinal 101, fork bands 107 are provided in the middle, into which the fork of the fork lift truck can be inserted. The exact position for the forklift is thus determined. On the upper side of the upper beam

104, a yoke 109 is formed to which a crane crane (not shown) can be hung. Such known shortened pallets 100 have the advantage that expensive individual packs of profiles are eliminated.

U in FIG. However, it is disadvantageous to the 12 known pallets 100 for the shortened material shown that these known pallets 100 for the shortened material occupy a large space for return transport and for empty storage, since only stacked stacks 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. Vertical pins 108 and support legs

105 furthermore, form mechanically weak spots of the known shortened pallet 100, which may be damaged. A further disadvantage is that although the fork straps 107 occupy the fork position, the loaded material is not supported until the fork also grasps the opposite fork strap 107 completely. Here, due to the inclined position of the known pallet 100 for the shortened material, the loaded material is damaged in the lower abutment region. The production of known pallets 100 for unabridged material is also expensive because a number of profiles have to 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 the unabridged material of the aforementioned type, which allows for safe handling during transport with greater stability, while in the empty state several pallets for the unabridged material must occupy only a small space.

This task is solved by a pallet for the unabridged material with the features of claim 1.

When there are several columns spaced substantially upright on the longitudinal beams of the shortened pallet on the outer sides spaced substantially perpendicularly upwards, the shortened pallets can be stacked in the empty state, whereupon the stacked shortened pallets are placed one above the other in the longitudinal direction offset by the width of the column or also stacked on top of each other, with the upper pallet for the uncut material placed on the columns of the lower pallet for the uncut material. The ladder-like construction of the pallet for the uncut material ensures high stability, so that typical high loads can also be transmitted to the pallet for the uncut material.

According to a preferred embodiment, the longitudinal beams form, with their underside, a bearing surface for laying the pallet for the uncut material. This eliminates the need to provide support legs which can easily be damaged when handling the pallet for the shortened material.

Because of the particularly good stability of the pallet for the shortened material and the small deflection of the longitudinal beams, these longitudinal beams are formed rectangular, with columns positioned on the longitudinally projecting sides. As a result, the columns can be set up at a comparable height so that horizontal loads can be transmitted to the sides well.

To form a common bearing surface, transverse reinforcements are attached to the upper side of the longitudinal beams. This does not result in a transition between

934 / B

r. cnree • r r R »* ^r transverse stiffeners any steps which may cause damage to the transported material.

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, while the closed shape of the rectangular profile prevents the material from being damaged from below. Also, when the fork is not inserted over the full width of the uncut material pallet, this prevents the pallet for the uncut material from being skewed.

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 pallets for the uncut material, mutual centering can be achieved which prevents lateral movement after the pallets for the uncut material have been folded.

In order to be able to convey long objects also through the pallet for the uncut material, a telescopically adjustable extension device is preferably located on at least one face of the pallet for the uncut material. The extension device also comprises two lateral 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 supported on 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.

The pallets for the shortened material also have pins on the outer sides of the longitudinal beams for attaching the crane sling. These pins do not protrude beyond the laterally positioned columns and are thus protected.

DETAILED DESCRIPTION OF THE INVENTION

The shortened pallet 7 consists of two spaced apart longitudinal beams 2 formed of a steel hollow profile which are connected to each other by means of transverse stiffeners 3. The longitudinal beams 2 have a substantially rectangular cross-section and are arranged vertically. A plurality of columns 4 are spaced from one another on the side wall 21 of the longitudinal beam 2.

The upper side 20 of the longitudinal beams 2 is connected to the upper side 30 of the transverse stiffeners 3 so as to form a common bearing surface for the long material. The longitudinal reinforcements 2 form, with their underside 22, a bearing surface for the pallet for the uncut material, the transverse reinforcements 3 having a small height and thus do not reach the ground.

In the central part there are two rectangular profiles 5, which are arranged in the lower recesses of the longitudinal beams 2. The rectangular profiles 5 have an opening 6 on opposite sides for receiving a fork of the forklift.

On the outer side wall 21 of the longitudinal beams 2 are located caps 7, on which the crane hinge 70 can be engaged. On the inner wall 23 of the longitudinal beams 2, there are strips 8 in which wall or frame elements can be fastened. In FIG. 1, the pallet 1 shown for the shortened material is formed both symmetrically to a plane in the middle of the two longitudinal beams 2 and also symmetrical to a plane in the middle perpendicular to the longitudinal beams 2.

As shown in FIG. 2 and 3, an extension device 9 may be provided on the front side of the longitudinal beam 2. The extension device 9 consists of profiles 90 which can be inserted into the longitudinal beams 2.

The profiles 90 can be fastened by clamping or frictional forces. Me too

934 / B it is possible to provide a separate locking device for fastening the extension device 9. The two profiles 90 are connected to each other by means of a transverse strut 91 on which the frame 92 is located. The frame 92 may be hinged or removable, for example, adjustable on the bands 8. The frame 92 may be provided with a filling plate 93.

The extension device 9 serves to secure the longitudinal material stored in the longitudinal direction on the pallet 1 for the shortened material, on the one hand, to prevent it from slipping during transport, but also to protect the longitudinal material against damage from the front. In addition, it is possible by means of a telescopic adjustment to allow the corresponding deposition of material of excessive length.

In FIG. 4A and 4B show an enlarged view of the column 4. The column 4 is fixed to the longitudinal beam 2 by means of a spacer 49, so that it is formed between the columns 4 and adjacent longitudinal beams 2 of the pallets 1 freedom for unabridged material. The column 4 is welded to the spacer 49.

In the upper part, the column 4 is provided with a projection 40 which has a pyramidal shape and is fixed to the column 4 by means of a weld 41. The projection 40 thus has sloping surfaces 42 which can be inserted into the lower opening 43 of the next column 4, thereby centering and aligning the two stacked columns 4.

As shown in FIG. 5A and 5B, the pallets 1 for the shortened material are formed symmetrically to the median plane M. Here, the further distance Y between the median plane M and the rectangular profiles 5 is smaller than the distance X between the median plane M and the pins 7. is substantially greater than the width of the pallet 1 for the shortened material, the length and width being, for example, in a 6: 1 ratio. In FIG. 6, a plurality of stacked pallets 1 for the shortened material are visible. Here, the columns 4, with their projections 40, engage in the lower openings 43 of the columns 4 arranged above them. In this position, stacked pallets 1 for the uncut material can be stacked.

934 / B

In FIG. 7, the same non-shortened pallets 7 are stored for transport within one another, wherein two superimposed pallets 1 for the shortened material are placed in the longitudinal direction offset by the width of the column

4. In this way, only a small space is required for empty pallets 1 for the shortened material.

In FIG. 8A to 8C, a second embodiment of a pallet 1 for a non-shortened material according to the invention is shown. Identical parts are designated with the same reference numerals.

In this exemplary embodiment, support shoes 45 are formed on the longitudinal beams 2, on which the columns 4 are pivoted for lifting to a vertical position. The support shoes 45 have a base support plate 46 having a rectangular cross-section that corresponds to the hollow chamber of the column 4 so that a pyramidal projection 40 of the column 4 can be inserted therein when stacking the pallets. For this purpose, the column 4 has a longitudinal bore 50 in which the pivot pin 48 is mounted. By means of this longitudinal opening 50, the column 4 can be raised or lowered, which serves to engage the locking lug 51 on the locking pin 49a and thereby lock in the upright position of the column 4. A stop 47 which limits the pivot is also provided. movement of the column 4 in the raised position. As shown in FIG. 8A, the columns 4 can be locked in an upright position and in a position parallel to the longitudinal beams 2. For this purpose, corresponding stops are provided on the longitudinal beam 2.

In FIG. 9 shows the pallets 1 for the shortened material according to FIG. 8A to 8C in the stacked position. This position corresponds to that of FIG. 6. In FIG. 10, the pallets 1 for the shortened material are stacked one above the other in a reducing manner, whereby the columns 4 are laid by means of said pivot mechanism to the longitudinal beams 2 of the pallets 1 for the shortened material.

In FIG. 11, there is shown a crane hinge 70 having four gripping arms 71 on a beam 74 which are spaced apart as pins 7 on the longitudinal beams 2. Hooks 71 are formed at the ends of the gripping arms 71

934 / B r c

73, which have the same orientation in the longitudinal direction. These hooks 73 can be gripped by the pins 7 on the longitudinal beams 2 so that the pallet 1 for the shortened material can be gripped by a crane hinge 70. The gripping arms 71 are positioned on the beam 74 by a grip 72 at a distance therefrom. By means of this crane hinge 70 it is possible to transport the pallet 1 for the shortened material, especially also in the horizontal direction.
