Dump elevator

Abstract

A dump elevator for use in conjunction with a fork lift truck and adapted to lift a load received from the fork lift truck to an elevated position and to subsequently dump the load through a chute into a receiving bin. The dump elevator comprises an upright frame having an upper and lower arcuate track disposed along two opposing sides of the frame. A carriage is disposed within the frame in an elevated position and includes rollers which are received and guided by the upper and lower tracks. A pusher assembly is disposed underneath and connected to the carriage so that after the fork lift truck has placed a load onto the carriage, the fork lift truck can then be used to lift the pusher assembly and thus raise the carriage. As the carriage is lifted the upper and lower tracks guide the travel of the carriage and simultaneously tilt the carriage so as to dump the load from the carriage when the carriage reaches a point near its apogee.
