Abstract
A brake device and a winch having the same are provided. The brake device includes a brake sleeve, a torsion spring, a sealing member and a braking assembly. The torsion spring is fitted over the braking assembly, and the brake sleeve is fitted over the torsion spring. The braking assembly is configured to drive the torsion spring to move between an expanded position and a retracted position, so as to lock and release the brake sleeve. The sealing member is arranged between the brake sleeve and the braking assembly, so that a sealing cavity is defined between the brake sleeve and the braking assembly.
