ABSTRACT:
The loading chute is constructed for ease and convenience in setting up for loading or unloading operations and also for ease and convenience in loading on a transporting vehicle for movement between various points of use. It comprises a framework having a forwardly extending base and an elongate ramp pivotally connected at its aft end to the lower aft end of the framework. A tension device, such as a winch and cable, raises the ramp about its pivotal connection to angle up and forward with respect to the base. The latter is somewhat longer than half the length of the ramp to support it in its elevated position when empty. Retractable shanks are lowered to support the front end of the ramp when it is loaded. To move the chute, the ramp is raised to a suitable angle, a truck is backed into position with its load platform under the forward portion of the ramp, and the chute is then tilted forward about the forward end of the base serving as a fulcrum until the ramp rests on the platform. The base is then drawn up so that the fulcrum clears the ground and then drawn up further to cause the base to contact the lower aft end of the vehicle body, such as the rear bumper, to secure the ramp in loaded position.
