Abstract
The invention is a variable displacement hydraulic motor-controlled hose reel drive system. The system includes a variable displacement hydraulic motor, having an electro-hydraulic control valve; a tachometer/position sensor; a reaction torque sensor; and a microprocessor which, depending upon data received from the system's position and reaction torque sensors, sends appropriate signals to the electro-hydraulic control valve.
