Cargo handling system
First Claim
1. A load support and transfer platform for use in moving objects off of a mobile, rectangular bed, the load support and transfer platform comprising:
- first, second and third segments disposed end to end in alignment with an end of the rectangular bed, the first and second segments being articulated and the second and third segments being articulated;
an extension mechanism for moving the first, second and third segments as a unit partially off the rectangular bed by way of the end;
each of the first, second and third segments having an independently actuable conveyor forming an upper surface of its respective segment and operable to allow an object supported by one of the segments to be transferred to another segment or off one end of the load support and transfer platform; and
a positioning mechanism for vertically repositioning the first segment.

Abstract
A handling system for incorporation in a trailer is used with palletized freight. The handling system incorporates a segmented, translatable platform. Among the segments is a principal or main segment which supports the palletized freight during shipping. The main upper surface of each of the segments is a conveyor. The conveyors are aligned from segment to segment to allow cooperative movement, respacing and unloading of the palletized freight on and between the segments and off of an end segment. The platform translation system allows the platform to be extended from an open end or side of the trailer. The segmentation of the platform allows the end and a mid segment to lower a piece of palletized freight to a surface below the level of the main segment of the platform.

7. Apparatus comprising:
-
a trailer;
a main conveyor section providing a support surface for cargo;
a mid conveyor section abutting the main conveyor section along an edge of each;
an end conveyor section abutting the mid conveyor section along an edge of the mid conveyor section opposite the edge abutting the main conveyor section;
a track installed on the trailer and supporting the main, mid and end conveyor sections in the trailer for horizontal movement within and out from the trailer;
the mid conveyor section and main conveyor section being articulated allowing the mid conveyor section to rotate through about ninety degrees downwardly from the main conveyor section when not supported by the track or a surface;
the end conveyor section and mid conveyor section being articulated allowing the end conveyor section to rotate through about ninety degrees to remain horizontal while the mid conveyor section is rotated on the main conveyor section; and
and each of the main, mid and end conveyor sections having a conveyor. - View Dependent Claims (8, 9, 10)

11. A trailer onboard handling system for discrete units of freight comprises:
-
a segmented, translatable platform;
a main segment of the translatable platform for supporting the discrete units during shipping;
a mid segment of the translatable platform attached for rotation on an axis provided by a first horizontal joint to the main segment;
an end segment of the translatable platform attached for rotation to the mid segment on a second horizontal joint parallel to the first horizontal joint;
a conveyor forming the principal upper surface of each of the segments;
the conveyors being aligned from segment to segment to allow cooperative movement, respacing and off loading of the discrete units on and between the segments and off of the end segment; and
a platform translation system for extending and retracting the translatable platform from an open end or side of the trailer. - View Dependent Claims (12, 13)
