The hoisting winch of a mobile crane is driven by two hydraulic motors connected to a common drive shaft. A control system for the motors includes manually controlled directional and speed control valves. The speed control valve optionally connects the motor hydraulically either in parallel for low-speed, high-torque operation or in series for high-speed, low-torque operation. A speed-limiting feature automatically shifts the speed valve to or maintains it in its low-speed position whenever the load is too heavy to be handled by the system in its high-speed mode. The hydraulic circuit of the control system also provides anticavitation protection for the motors when in its high-speed mode.
