Abstract: A stacking system for conveying bulk material includes a conveyor frame designed to support a conveyor belt, the conveyor frame including forward and rear portions, a hopper designed to receive the bulk material, the hopper being mounted adjacent the rear portion of the conveyor frame, an engine for providing power to the stacking system, a drive pulley for driving the belt, and an idler pulley disposed generally below the hopper. An improvement comprises a counterweight disposed above the idler pulley and to the rear of the hopper. Another way to describe the disclosure is as a counterweight for a belt-type, portable stacking conveyor having forward and rearward portions, a drive pulley disposed toward the forward portion of the conveyor and an idler pulley disposed adjacent the rearward portion of the conveyor, the counterweight being disposed immediately above the idler pulley.
