The present invention relates to a cable drum for a cable winch of a cable drive, having a drum shell and two flanged wheels which adjoin the drum shell at the ends, wherein the drum shell and/or the flanged wheels are produced from fiber-reinforced composite material, wherein the drum shell and/or the flanged wheels have a multi-shell structure having at least two walls made of fiber-reinforced composite material, which walls are spaced apart from each other and connected to each other by a foam core.

A rope guiding device used in connection with the rope hoist to guide a hoisting rope. The inventive rope guiding device of a rope hoist for guiding a hoisting rope on a rope drum which rope drum may be adapted to rotate in order to wind the hoisting rope around the rope drum or off the rope drum to hoist and lower a load adapted on the hoisting rope, the rope guiding device comprising at least one guiding element to guide the hoisting rope of the rope hoist, and a screw to move said at least one guiding element, is characterized in that wherein the rope guiding device is supported to the body of a trolley of the rope hoist by means of a support arrangement which support arrangement comprises first pivotings and second pivotings adapted to a substantially 90-degree angle in relation to said first pivotings.

The present disclosure belongs to the technical field of fishing operation equipment in fishery, and relates to a net hauler for a trawler. The net hauler includes two rope drums, a drum rotation shaft is disposed on each rope drum and includes a first rotation shaft and a second rotation shaft, a drum is disposed on the first rotation shaft, a cylindrical housing is disposed between two ends of the first rotation shaft and the second rotation shaft, a pivot is disposed on the cylindrical housing. The present disclosure has advantages of changing a net hauling speed and improving a fishing efficiency.

A portable hoist and a winch. The winch and hoist can be integrated in a single housing or can be attached to one another. The portable hoist provides a user with the ability to hang the portable hoist without the use of other lifting devices, cranes, or rigging and allows the user to do it in a safer manner with less man power. The portable hoist can have a safety pin configured to secure the winch hook in a secured position so as to allow the hoist to lift increased loads.

The invention relates to an abseiling device comprising a bidirectionally rotatable guiding arrangement (25) for guiding a pulling means (26); further comprising a braking mechanism (30) that is coupled to the guiding arrangement (25); a driving means (34; 35) can be connected to the guiding arrangement (25) so as to actuate the guiding arrangement (25). In order to create an abseiling device that prevents an individual from being injured or parts of the abseiling device from being damaged during rescue operations in particular of people, a mechanical torque limiter (33) decouples the driving means (34; 35) and the guiding arrangement (25) or the pulling means (26) when the torque exceeds a certain threshold value.
