The profiles of double motor winch

Fromwinch electric towing winch has the motor, brake and first gear reduction on one side of the drum, and the remaining gear reductions attached at the other end.  In a double motor winch, you effectively have one set of motor, brake and all gear reductions on each end of a single drum on a single frame.
Of course, to power a double motor winch, you need twice the power of the equivalent standard winch.  For hydraulic power, the typical solution is to distribute the hydraulic flow from a common source to each motor.  For electric power, you simply provide the voltage and current demanded by the motors.  Compared to the equivalent standard model. Or it can be used with a different gear ratio or larger diameter drum to produce twice the line speed at a given line pull.
