Abstract:
A system for controlling motion of a hydraulic actuator on a refuse collection vehicle. The system includes an operator input device configured to produce a proportional electrical signal that is proportional to the degree of motion of the operator input device. The system further includes a proportional pneumatic control valve that is configured to produce a pressurized air control signal in proportion to the proportional electrical signal, and a hydraulic control valve that is configured to selectively control flow of hydraulic fluid to a hydraulic actuator in response to the pressurized air control signal.
