An ejector for a forestry winch, the ejector may include a rotating ejector roller by means of which a synthetic rope is guided and deflected, wherein the ejector has at least one rotating pressure roller driven by a drive motor and by means of which the synthetic rope is pressed against the ejector roller.

The lifting device includes a first drum around which a wire is wound, a first motor that rotates the first drum, a second drum around which the wire fed from the first drum is wound, and a second motor that rotates the second drum. The first motor is driven to rotate the first drum so as to lift the wire, and the second motor is driven to rotate the second drum to lift the wire fed from the first drum.

A winch for a power generating system using a tethered airborne device, the winch comprising a drum rotatable about its main axis a guiding apparatus arranged to guide an airborne device tether to wind and unwind around the drum; wherein the drum is rotatable relative to a pivot point to move in a first plane and the guiding apparatus is disposed relative to the drum to move along part of an orbital path around the drum in a second plane substantially perpendicular to the main axis of the drum, thereby allowing alignment of the winch with respect to an unwound length of the tether.

Systems are provided for a fairlead, and in particular to a hawse fairlead. In one example, the fairlead may include a wear insert positioned within a first opening of a fairlead frame configured to guide a rope and/or cable. The wear insert may be constructed from a denser material than the frame.
