Title: Systems for container handling
IPC: B66C23/42
Filed: 1996-03-29
Abstract: 1. A mechanism for loading, unloading or trans-shipping a container (7) onto a tray (1) attached to or attachable to a truck or trailer vehicle, the mechanism including an assembly mounted at each end of the transverse assembly (8), incorporating a telescoping boom mounted by a pivot (11) at the centre of the assembly, characterized in that a lower part (26) of the boom incorporates an extension (28) to which opposed hydraulic rams (15, 16) are linked, the hydraulic rams are adapted to control the swinging movement of the boom (12) through the central pivot (11) from one side of the tray (1) to the other when one ram (15, 16) retracts and the other ram (15, 16) extends. 2. Mechanism according to Claim 1, characterized in that each assembly (8) incorporates on each side of the tray (1) a stabilising leg (18. 29), the arrangement being such that in a travelling position the stabilising legs are parked generally upright on or relative to the tray (1) and the boom (12) is retracted to be either upright on the transverse assembly (8) or angled slightly from vertical to minimise the vertical height of the vehicle, and in an operative position the stabilising legs can be down in contact with the ground. 3. System for handling containers, comprising a tray onto which a container (7) is loaded or unloaded,  a pair of telescoping booms (12) mounted at the centre at each end of the tray(1) to provide swinging movements of the boom relative to the tray during lifting the container (7),  two pairs of hydraulic rams (15, 16), adapted by one pair at each end of the tray (1) to control the swinging movement of a corresponding boom (12),  characterized in that each pair of hydraulic rams (15, 16) is linked to the lower part (26) of the corresponding boom (12) and to the inner part (27) of the boom, which is extended from the lower part during lifting the container (7). 4. System according to Claim 3, characterized in that each pair of hydraulic rams (15, 16) is linked to the lower part (26) of the corresponding boom (12) near the point (11) around which the boom turns. 5. System according to Claim 3, characterized in that the lower part (26) of each boom (12) incorporates the extension (28) to which a pair of corresponding hydraulic rams (15, 16) are linked. 6. System according to Claim 3, characterized in that the container is lifted by a simultaneous movement of one end of each boom, and a corresponding pair of the hydraulic rams is linked to the other ends of the boom. 7. System according to Claim 3, characterized in that each hydraulic ram (15, 16) links the boom (12) and corresponding angle of the tray. 8. System according to Claim 3, characterized in that the telescopic booms (12) enable to turn to any direction from the tray (1) or cross the tray during loading or unloading the container (7). 9. System according to Claim 3, characterized in that incorporates two pair of legs (18, 29) on each side of the tray (1) to stabilize the installation during lifting of the container. 10. System according to Claim 3, characterized in that it can be used to load containers onto a road transport means. 11. Road transport means, incorporating a device to handle the container according to any of Claims 3-10. 12. Transverse assembly for the system of container handling, incorporating a base (9, 31)which is oriented laterally to the tray or the pallet(1), telescopic boom (12) which turns laterally towards the central point (11)of the base (9, 31), a pair of hydraulic rams (15, 16) to link the base (9, 31) and the boom (12) to control the movement of the boom during lifting of the container (7), characterized in that the boom incorporates the lower part (26) and the retractable element (27), with hydraulic rams (15, 16), linked to the lower part. 13. Assembly according to Claim 12, characterized in that the hydraulic rams (15, 16) are linked to the boom (12) symmetrically, due to which the containers are lifted from any side of the tray or the pallet (1). 14. Assembly according to Claim 12, characterized in that the lower part (26) of the boom (12) incorporates the extension (28) to which a pair of the hydraulic rams is linked. 15. Assembly according to Claim 12, characterized in that further incorporating a pair of the stabilising legs (18, 29). 16. Road transport means incorporating the assembly according to any of Claims 12-15. 17. System for the container handling, incorporating  tray (1) onto which the container (7) is loaded or unloaded,  device for telescopic booms (12), mounted at the centre of each end of the tray to control lateral movement towards the tray during lifting of the container (7), and  device for the hydraulic rams (15, 16) which is linked at each end of the tray is linked to control lateral movement of the corresponding device for the telescopic booms (12);  characterized in that the device for the hydraulic rams (15, 16) at each end of the tray is linked to the lower part (26) of the corresponding device for the telescopic booms (12), due to which the inner element (27) of the device for the boom extends from the lower part (26) during lifting the container (7). 18. Assembly for the system of container handling, incorporating a base (9, 31) which is oriented laterally to the tray or the pallet (1),  device for the telescopic booms (12), which turns laterally towards the central point (11)on the base (9, 31), and  device for the hydraulic rams (15, 16), which links the base (9, 31) to the device for the telescopic booms (12) to control turning the boom during lifting the container (7), characterized in that the device for telescopic booms incorporates the lower part (26) and element (27) which extends using the device for the hydraulic rams (15, 16), linked to the lower part.
