ABSTRACT:
A loading and unloading system for trucks and trailer has a conveyor belt extending along a bed of a truck or trailer between front and rear wind-up rolls. For loading the vehicle the conveyor belt is wound onto the front roll and for unloading the vehicle it is wound onto the back roll. In order to prevent the belt from being pulled off the respective rolls a control system is provided which has a follower engaging the outer surface of the belt wound on one of the rolls. When the roll attains a predetermined maximum or minimum diameter depending on the amount of belt wound thereon, the follower operates a hydraulic valve to terminate the drive for the belt. The control operates in one direction responsive to a maximum predetermined diameter and in the other direction responsive to a minimum predetermined diameter.
