- A) a longitudinally adjustable boom system located in a cargo handling facility for extending into a cargo vehicle to be loaded or unloaded;
B) front-end load handling means, attached to the adjustable boom system, for lifting and placing palletized and non-palletized loads in a vehicle; and
C) conveyor system means for bringing palletized and non-palletized loads to be loaded to the front-end load handling means for subsequent placement in the cargo vehicle;
D) the front-end load handling means comprising;
1) a mast;
2) vertically movable means movably connected to the mast for moving said load handling means vertically;
3) horizontal support members attached to the front-end load handling means;
4) transverse movement means movably attached to the horizontal support members for transporting said front-end load handling means in a transverse direction in the cargo vehicle; and
5) a rotating bearing means for supporting and permitting the vertically movable means to rotate three hundred sixty degrees in a horizontal plane;
E) the cargo vehicle having a floor and the front-end load handling means further comprising substantially non-load bearing rollers which come in contact with the floor of the cargo vehicle to be loaded or unloaded to provide torsional stability for the pallet handling adjustable conveyor only as loads are moved transversely along the horizontal support members and only when torsional forces are strong enough to twist the pallet handling adjustable conveyor from a horizontal position;
F) wherein the movement of the longitudinally adjustable boom system and the movement of the front-end load handling means are controlled via logic means adapted to accept cargo vehicle dimensions for the purpose of determining the front-end load handling means position within the cargo vehicle to be loaded or unloaded, the pallet handling adjustable conveyor further comprising means for automatically measuring the cargo vehicle dimensions, storage means for storing cargo vehicle dimension information, the logic means adapted to automatically control the front-end load handling means in loading and unloading the cargo vehicle based on the cargo vehicle dimension information; and
G) the front-end load handling means transverse movement means being selected from the group consisting of electrically actuated movement means and hydraulically actuated movement means.

Abstract
A material handling adjustable conveyor comprising an adjustable boom, and front-end material handling device with four degrees of freedom to allow loads to be lifted and rotated into position and placed or removed from an over-the-road vehicle or unloaded from such a vehicle. During the loading or unloading procedure, the load is only supported by the front-end material handling device. Some of the load is borne by the floor of the cargo vehicle when more than minimal torsion forces are applied to the front-end material handling device. The material handling device is computer controlled based upon the dimensions of the vehicle being loaded and unloaded and further comprises sensors for fine adjustment of front-end handling device motion during the course of the loading or unloading. Other senors can be used to measure and record the internal dimensions of a cargo vehicle. The dimensions can be stored in an on-board computer, which will subsequently automatically control the loading and/or unloading movements of the front-end material handling device.
