Abstract (en)

[origin: EP0678473A2] The lifting winch has an electric drive motor (11), coupled to the winch drum (5) via a cog wheel drive train with at least one pair of drive cogs having angled cog teeth. One of these drive cogs is attached to a shaft which is displaced axially between 2 end positions in the drive housing (3), with an attached permanent magnet cooperating with a magnetic field sensor for indicating the shaft position. The shaft is acted on by a spring bias which holds it in one end position unless the exerted force is above a defined limit value, at which it moved into the second end position. <IMAGE>
