Winch and winch drum

摘要

Disclosed is a winch drum (2) for rotation about a rotation axis. The winch drum (2) has a rope-receiving surface (6) with a plurality of raised ridges (14) defining substantially helical channels between them. The channels provide guidance for rope along the rope-receiving surface (6) at least during rope release. The ridges (14) have a meandering shape extending around the drum (2), formed from a series of alternating circumferential (18) and axially inclined (20) ridge elements.
