Abstract

This invention relates to a loading pallet. Conventional pallets of wood show deficiencies with respect to durability and service life. In order to eliminate these deficiencies and also other ones involved with conventional wood pallets, according to the present invention a pallet with a load-carrying platform of corrugated sheet metal is proposed, which platform (3) is supported at its opposed edges by supporting beams (4) of substantially U-shaped cross-section, which beams extend perpendicularly to the corrugations (2) and are formed integral with the platform by folding the metal sheet three times substantially perpendicularly, so that its free end portions (10) form the inside of the respective supporting beam and constitute supporting legs for the platform spaced from the outer edges thereof, and said end portions (10) are locked relative to the platform in a substantially vertical position and have between themselves a free space beneath the platform which permits the insertion of the lift forks of a truck from one side or the other.

Claims

1. A loading pallet having a load-carrying platform of corrugated sheet metal, characterized in that the platform (3) is supported at its opposed edges by supporting beams (4) of substantially U-shaped cross-section and extending perpendicularly to the corrugations (2), which beams are formed integral with the platform by bending the sheet three times substantially at right angle, so that its free end portions (10) form the inner surface of the respective supporting beam and constitute supporting legs for the platform spaced from the outer edges thereof, and said end portions (10) are locked relative to the platform in a substantially vertical position and have between themselves a free space beneath the platform to permit insertion of the forks of a loader from one side or the other, and each supporting beam (4) is provided with spaced downwardly open recesses (19), which permit insertion of the forks of a loader also from these sides of the pallet, said platform and said beams being all formed from said corrugated sheet metal with a plurality of its full corrugations extending contiguously and integrally throughout the platform and beams.

2. A pallet as defined in claim 1, characterized in that each of the free end portions (10) for its locking relative to the platform (3) is inserted with its end into a locking groove (11) provided in a bar (12) at the lower surface of the platform and extending perpendicularly to the corrugations.

3. A pallet as defined in claim 2, characterized in that each such bar (12) has depending carrying surfaces (16).

4. A pallet as defined in claim 3, characterized in that such carrying surfaces (16) are formed on both sides of the locking groove (11) of each bar.

5. A pallet as defined in claim 2, characterized in that each bar (12) has a flat member (14) aligning with the bottom of the locking groove, by which member and the locking groove bottom the bar rests against the lower surface of the platform and is connected to the same by locking tips (15), which are bent over and punched out in the flat member and in the bottom of the locking groove and in the platform.

6. A pallet as defined claim 2, characterized in that each bar (12) is fixed with its longitudinal edge remote from the attachment member in folds in the corrugation formed at the bending operation at the perpendicular transition between the platform and the supporting beam.

7. A method for manufacturing a pallet of sheet metal as defined in claim 1, characterized in that metal sheet openings (24) are punched to form recesses (19) of the supporting beams, and that the corrugated metal sheet first thereafter is bent at right angle to the corrugations at its edges to form the supporting beams (4) integral with the platform (3).

8. A method as defined in claim 7, characterized in that the metal sheet is corrugated after the punching of said openings (24) and cut to desired lengths.
