Abstract

The invention relates to a shipment loading system for loading shipments into an unit load device, comprising a conveyer, a platform and a cargo space for placing the unit load device on a static rack, whereby the conveyer is provided on a ground floor and tiltable across its longitudinal axis, the conveyer comprises an extendo extending the conveyer along the longitudinal extension of the conveyer, the extendo is movable between a retracted position and an extracted position, in the extracted position the extendo faces the cargo space, the platform is movable between a first position and a second position along the longitudinal extension of the conveyer, in the first position the platform faces the cargo space and at least in one of the first and second positions the platform is arranged between the ground floor and the conveyer.

First claim

The invention claimed is:

1. A shipment loading system for loading shipments into a unit load device through an opening in the unit load device, comprising:
a conveyer;
a platform provided on a ground floor, wherein the platform comprises a load deck elevated above the ground floor and a handrail that extends above the load deck, wherein the load deck is adapted for an operator to stand on while loading the unit load device; and
a cargo space for placing the unit load device on a static rack ,
wherein the conveyer is provided on the ground floor and tiltable across a longitudinal axis,
the conveyer comprises an extendo extending the conveyer along a longitudinal extension of the conveyer,
the extendo is movable between a retracted position and an extracted position,
in the extracted position the extendo faces the unit load device in the cargo space,
the platform is movable relative to the conveyor between a first position and a second position along the longitudinal extension of the conveyer,
in the first position the platform faces the opening of the unit load device in the cargo space and
at least in one of the first and second positions the conveyer is above and overlaps the platform.

2. The shipment loading system according to claim 1 , wherein in the second position the platform does not face the cargo space, in the second position the platform is arranged between the ground floor and the conveyer, and/or in the retracted position the extendo does not face the cargo space.

3. The shipment loading system according to claim 1 , wherein at least one of the conveyer and the extendo are provided as at least one of the group consisting of a belt conveyer, a band conveyer, and a roller belt.

4. The shipment loading system according claim 1 , wherein the platform comprises one pair of casters and one pair of v-groove wheels for running in a track on the ground floor.

5. The shipment loading system according to claim 1 , wherein the platform comprises a load deck, the platform comprises a height of at least two feet, and the load deck is arranged at said height.

6. The shipment loading system according to claim 1 , comprising a spiral chute arranged adjacent to the conveyer such that shipments sliding on the spiral chute land on the conveyer.

7. The shipment loading system according to claim 1 , comprising the unit load device having an opening for accessing the interior of the unit load device and, if the unit load device is placed onto the cargo space, the opening faces the platform in the first position and the opening faces the extendo in the extracted position.

8. The shipment loading system according claim 7 , wherein the opening comprises a planar extension and, if the unit load device is placed onto the cargo space, the planar extension of the opening is parallel to the longitudinal extension of the conveyer.

9. The shipment loading system according to claim 1 , wherein the shipment loading system is adapted to:
a) place the unit load device on the cargo space;
c) move a platform from a second position to a first position; and
d) extract an extendo from a retracted position into an extracted position.

10. The shipment loading system according to claim 9 , wherein the shipment loading system is adapted to:
b) load the unit load device with forkable shipments with a drivable machine.

11. The shipment loading system according to claim 10 , wherein the shipment loading system is adapted to:
e) retract the extendo from the extracted position into the retracted position; and
(f) move the platform from the first position to the second position.

12. The shipment loading system according to claim 1 , wherein the conveyer is adapted to extend and retract the extendo to follow the movement of the platform.

13. The shipment loading system according to claim 1 , wherein the platform further comprises roller wheels for moving the platform between the first position and the second position.

14. The shipment loading system according to claim 1 , wherein the platform further comprises a motorized means for moving the platform between the first position and the second position.

15. The shipment loading system according to claim 1 , further comprising a ladder that extends below the load deck toward the ground floor.

16. The shipment loading system according to claim 15 , further comprising a spring gate positioned above the ladder that provides operator access through the handrail.

17. The shipment loading system according to claim 1 , wherein a relative longitudinal position of a pivot point of the conveyor and the static rack are fixed relative to each other.

18. The shipment loading system according to claim 17 , wherein, in the second position, the platform does not face the opening of the unit load device in the cargo space such that a forktruck can access the opening in the unit load device when the unit load device is on the static rack.

19. The shipment loading system according to claim 1 , wherein the platform further comprises a first support that extends vertically between one side of the platform and the ground and a second support that extends vertically between an opposite side of the platform and the ground.

20. The shipment loading system according to claim 1 , wherein neither the conveyor belt nor the extendo are attached to the platform.
