<p>A winch comprises a drive pulley (13) for a lifting cable (14) which is rotatable in optional direction by means of a driving motor (10), and a guide means (17) for the lifting cable (14) which is connected to the drive pulley (13) through a slip coupling (26, 27, 28) and arranged for limited rotation, the lifting cable being movable by said guide means between an engagement position, in which it is located in drive engagement with the drive pulley (13), and a release position, in which it is located out of drive engagement with the drive pulley (13) and is supported by an alternative supporting means (18) for the lifting cable (14), over which the lifting cable (14) may be let out without being driven from the drive motor (10). The guide means (17) is arranged to move the lifting cable (14) between the engagement position and an axially displaced release position in which the lifting cable (14) is supported axially at the side of the drive pulley (13) by the alternative supporting means (18).</p> |
