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.
