ABSTRACT:
A self-tailing winch with pivoting teeth comprising a fixed support constituting a base, a drum mounted to rotate about the fixed support, a vertical shaft for driving the drum in rotation and connected thereto via a transmission including a stepdown gear train, and an automatic clamping mechanism for clamping cable or rope wound around the winch, which clamping mechanism is mounted at the top of the drum in order to form a self-tailing head for the rope. The automatic cable or rope clamping mechanism comprises a plurality of pivoting teeth distributed around the bottom portion of a block on top of the drum and constrained to rotate therewith, and springs mounted in the block in order to exert downwards pressure individually on each of the pivoting teeth which themselves exert pressure individually on the rope in order to pinch the rope against the top end of the drum, thereby enabling the same winch to operate effectively with ropes of different types and of different sections.
