The gearing is of the compound planetary type which can provide very high ratios with low friction. The low friction yields greater efficiency, and permits retaining the gearing in operation idly during free fall, ready for fail-safe braking using it. A separate brake is provided for stopping free fall, when free fall is provided The winch motor is preferably of the two unit type, with valving for two speeds. operation of either manual valve (normal opera- tion or free fall) from its neutral position neutralizes the other. Numerous automatic valves are included in a valving block, pro- viding simplicity of piping.
