摘要： Braking systems and methods are provided for a drum wench system having a winch drum having an outer surface and a winch drum braking system. The winch drum braking system has a first brake having a first brake lining, located adjacent to the winch drum, and a first three-ring ratchet linkage system connected to the first brake lining. The first three-ring ratchet linkage system is rotatable and adapted to move the first brake lining to a first position or a second position with respect to the outer surface of the winch drum. In the first position, the first brake lining contacts the outer surface of the winch drum to apply break force thereon, and, in the second position, the first brake lining is separated from the winch drum.
