Abstract
A braking device for a winch comprises a braking bush, a brake driving shaft having one end connected to an output shaft of the motor and another end of the brake driving shaft having a first axial protrusion. A brake driven shaft defines an end rotatably disposed in the braking bush and having a second axial protrusion opposed to the first axial protrusion. A brake shoe is disposed between the first axial protrusion and the second axial protrusion. An elastic member is connected to the second axial protrusion and the brake shoe and normally urges the brake shoe toward the first axial protrusion. A winch having the braking device is also disclosed.
