Claims

[Scope of utility model registration request]

A winch drum driven by a hydraulic motor connected via a clutch, a clutch cylinder that acts in close contact with the clutch, a brake that biases the winch drum in the braking direction with a spring, and a brake that resists the biasing force of the spring. In a hydraulically driven winch consisting of a brake cylinder that acts in the release direction, the clutch operation valve installed in the oil supply and drainage path of the clutch cylinder and the operation valve that controls the brake installed in the brake cylinder oil supply and drainage path are electromagnetically operated. □
A hydraulically driven winch characterized by a dynamic poppet type on-off valve.
