摘要

The device has a cylinder (32) cased on a cone formed by two semi-shells (8) for retightening the semi-shells to obtain a clutch brake along a cable (3) which crosses the cylinder and the semi-shells (8) from top to bottom, where the cylinder houses a compression spring (21) on top. Winching straps are connected to handles (7, 11) by rings, where the handles retain a load.
