Abstract
A system for controlling the tension in a conveyor assembly includes a conveyor, a hydraulic motor, a pump, a hydraulic fluid reservoir in fluid communication with the pump and in fluid communication with the hydraulic motor, a first valve in fluid communication with the pump and the hydraulic motor, a hydraulic actuator, and an actuator control valve assembly. The conveyor includes a continuous, flexible conveying member rotatably driven around a drive wheel at one end, the drive wheel being connected to the hydraulic motor which receives pressurized hydraulic fluid from a first supply line to drive the motor in a first direction, and from a second supply line to drive the motor in a second direction. The actuator control valve is in fluid communication with the first motor supply line, the hydraulic reservoir, and a first and second port of the actuator.
