A support or jig (6) for handling packs including elongated articles, especially lumber packs (2a,2b), is adapted to support the lumber pack during the handling and to be brought to an appropriate position in front of an input opening in a rack (1) for the transfer of a loading pack between the handling device (6) and the rack (1). During the transfer between the handling device and the rack, the weight of the pack gives rise to a tilting moment. Therefore, the device (6) is provided with supporting arms (10a,10b) which securely engage supporting means (11a-11e) in the rack (1) so that the handling device (6) during the transfer operation is supported in the area of the rack openings. The arms are locked in their extended positions by the load and hold the jig next to the rack, even if a tilting moment is created during transfer.

1. A jig (6) for handling of packs including elongated articles, especially lumber packs (2a, 2b), comprising a frame having transverse transport rollers (7a-7e) adapted to support the packs during handling, the frame being positioned in front of a rack opening in a rack, the rack having rollers (4a
1. A jig (6) for handling of packs including elongated articles, especially lumber packs (2a, 2b), comprising a frame having transverse transport rollers (7a-7e) adapted to support the packs during handling, the frame being positioned in front of a rack opening in a rack, the rack having rollers (4a, 4b) for the transport and support of the packs so that the transfer of the pack between the jig (6) and the rack (1) can take place by rolling the pack from the rollers (7a-7e) on the jig (6) to the rollers (4a-4b) in the rack (1), the invention being characterized in that the jig (6) further comprises supporting arms (10a, 10b), each arm having a substantially hook-shaped means (12) at one end adapted for hooking onto a horizontal supporting iron (11a-11e) in the rack (1) below the rollers, the arms constituting a support for the device in a vertical direction during the transfer of the article to the rack, and including means for resisting the reaction forces which can develop in the horizontal direction when movement of the pack is blocked during the transfer, the resistance being created by a skewed relationship between each arm and a guide means. 2. The jig as claimed in claim 1, characterized in that the supporting arms (10a,10b) in their position of use form an extension in the longitudinal direction of the structure, at least one supporting arm (10a,10b) being provided at each transverse end of the frame. 3. The jig as claimed in claim 1 wherein each supporting arm (10a,10b) can be displaced telescopically in a guiding means (13) mounted to the frame. 4. The jig as claimed in claim 1, further comprising tine-receiving means on the frame below the rollers adapted for receiving the tines of a lifting means (9a), for example, the tines of a forklift truck (9), the tine-receiving means being accessible from either side of the frame. 5. The jig as claimed in claim 1, further comprising a plurality of spaced lugs (16a-16d) on the top of the frame adapted for receiving claws (20) on a lifting yoke (17) so that the jig may be used in a crane operation. 6. The jig as claimed in claim 2, further comprising tine-receiving means on the frame below the rollers adapted for receiving the tines of a lifting means, such as the tines of a forklift truck, the tine-receiving means being accessible from either side of the frame. 7. The jig as claimed in claim 6, further comprising a plurality of spaced lugs (16a-16d) on the top of the frame adapted for receiving claws (20) on a lifting yoke (17) so that the jig may be used in a crane operation. 8. The device as claimed in claim 3, further comprising a plurality of spaced lugs (16a-16d) on the top of the frame adapted for receiving claws (20) on a lifting yoke (17) so that the jig may be used in a crane operation. 9. The jig as claimed in claim 3, further comprising power means attached to the frame for driving the rollers. 10. The jig of claim 9 wherein the power means includes an electric motor and chain driven by the motor. 11. The jig of claim 10 wherein the frame includes hollow side members and wherein the chain is hidden within a side member. 12. A device for handling of elongated articles, such as lumber packs, comprising: (a) a frame for holding the article, allowing elevation of the frame and article for off-loading, the frame including at least one support arm guide means; (b) a plurality of spaced, parallel, transverse rollers on top of the frame for supporting the article and allowing rolling movement of the article in a predetermined direction; (c) at least one support arm extensible from the guide means of the frame in the predetermined direction, the arm extending below the rollers to avoid interference with movement of the article above the arm on the rollers from the frame to the rack; and (d) connecting means on an end of the arm for securely connecting the arm and frame to a horizontal support iron of a storage rack, wherein the arm constitutes a support for the device in a vertical direction during transfer of the article to the rack and an abutment for the jig against reaction forces which can develop in the horizontal direction when movement of the article is blocked during the transfer from the frame to the rack, the resistance being created by a skewed relationship between the arm and guide means. 13. The device of claim 12, further comprising at least one other support arm extensible from the frame opposite the first support arm from a second support arm guide means on the frame, the other support arm having a connection means for securely connecting the frame to the rack. 14. The device of claim 12 wherein the guide means includes a tubular receiver for telescoping interfitting engagement with the support arm so that the support arm may be retracted within the receiver and so that, when connected to the rack and loaded to form the skewed relationship, the arm frictionally engages the receiver at a skewed angle to limit extension or retraction of the support arm by the reaction forces. 15. The device of claim 14 wherein the frame includes forklift tine receivers on the bottom of the frame below the rollers, the tine receivers allowing raising of the frame with a forklift truck, and being accessible from either side of the frame. 16. The device of claim 14 wherein the connecting means includes a connection plate mounted substantially vertically to the end of the arm and a downwardly directed angle iron section at the top end of the connection plate for hooking to a horizontal support iron of the rack. 17. The device of claim 14, further comprising at least one roller bearing transversely mounted within the tubular receiver, the support arm fitting within the receiver above the roller bearing and pivoting about the roller bearing to form the skewed angle. 18. A device for handling of elongated lumber packs in a warehouse, comprising: (a) a frame for holding the lumber pack; (b) a plurality of parallel rollers mounted on the top of the frame to receive the pack, the pack rolling on the rollers during movement; and (c) at least one extensible support arm mounted to the frame below the rollers in a tubular receiver, the arm including a connector for securely connecting the arm to a storage rack, the arm and receiver forming an abutment against horizontal reaction forces which could move the frame away from the rack by creating a skewed relationship wherein the support arm is locked within the receiver. 19. The device of claim 18, further comprising power means on the frame for driving the rollers in a predetermined direction. 20. The device of claim 19, further comprising tine-receiving means on the frame below the rollers for receiving the tines of a forklift truck, the means being accessible from either side of the frame, and wherein the tubular receiver includes at least one roller bearing transversely mounted within the receiver below the support arm, the bearing easing movement of the unloaded arm and being a fulcrum for the skewed relationship when the arm is loaded.
