The invention relates to rope drives operating with high-strength fiber ropes, such as crane hoisting gear, boom adjustment units, trolley running gears, and the like. The invention relates in particular to a rope drum (1) for such a fiber rope drive, having a drum body (2) for winding the fiber rope, flanged wheels (3) enclosing the drum body, and a rope end fastening device (9) for fastening a rope end to the rope drum. According to the invention, the rope end fastening device of the rope drum comprises two adjacent strand guiding channels (13, 14), which lead to a rope deflection element (15), around which the rope end can be passed, such that one rope strand comes to lie in each of the two strand guiding channels, and furthermore a clamping device (26) provided for the strand guiding channels for clamping at least the rope strand that is passed back around the rope deflection element, in the strand guiding channel provided for said rope strand.

Es wird eine Seiltrommel (1) mit darauf aufgewickeltem Zugseil (6) für eine Wickelvorrichtung mit Wickelwelle für die Seiltrommel (4) vorgeschlagen. Erfindungsgemäß ist das auf die Seiltrommel (1) aufgewickelte Zugseil mit einer Lage aus nachgiebigem Material (7) überdeckt, sodass das Zugseil (6) daran gehindert ist, sich selbsttätig von der Seiltrommel (1) zu lösen, insbesondere aufzuspringen, und dass das nachgiebige Material (7) dergestalt ist, dass das Zugseil (6) bei Zug am Zugseil (6) mit vordefinierter, vergleichsweise leichter Zugkraft einen sich von der Seiltrommel abhebenden Zugseilabschnitt freigibt, aber verbleibende Windungen nach wie vor überdeckt und damit fixiert bleiben.

The invention concerns a traction winch (1) for winching an elongated article (16) having a high-tension end connectable to a load and a low-tension end connectable to a storage device and a method for performing such a winching The traction winch comprises two or more rotatable drums (2,3) arranged adjacent to each other with their rotational axes substantially parallel. Each of said drums has a plurality of parallel, circumferential sheaves (4-15) with groove, the sheaves being axially offset with respect to each other to allow wrapping of the elongated article around the sheaves of both drums in a spiral fashion. The plurality of sheaves includes fixed sheaves (6-12, 14, 15) which are stationary relative to their underlying drum and rotatable sheaves (4,5,6,13) which are rotatable relative to their underlying drum. The majority of the rotatable sheaves of at least one of the drums is arranged adjacent to each other on a high load supporting side of the winch.

A slewing apparatus, comprising a slewing bearing means for the operation of a reel. A first slewing bearing (10) is configured to carry torsion and axial loads in the reel, while the second slewing bearing (20) is configured not to carry substantial torsion and axial loads in the reel. Thereby the second slewing bearing (20) functions as a back-up bearing for the reel, while the first slewing bearing (10) operates the reel and thus serves as the primary slewing bearing for the reel.

A drum assembly (100) for accommodating.a well access line. The drum of the assembly may include a core (107) coupled to flanges (115) at either side thereof. The core may be configured to accommodate the well' access line thereabout. Additionally, the core may be configured with an inner portion for coupling to the flanges at an arcuate junction (200) therebetween as well as a collar (110) about the inner portion for directly accommodating the well access line in a stable manner.

A longline fishing system which is attached to a fishing boat for the purpose of lessening wear and tear on the fishing line has an improved reel and an auxiliary hauler. The reel is made from a plurality of arcuate sections forming a core. End plates are attached to each end of the core. The diameter of the core and the diameter of the end plates are related to prevent over stressing the line. The auxiliary hauler is placed between the stern and the reel to accept a portion of the hauling load.
