摘要： A double drum traction winch supporting a first and second rotatable drum is provided. The circumferential surface of each drum is provided with circumferential grooves perpendicular to the rotational axis of the drum. The grooves of each drum are subdivided in a first set of grooves for guiding a first wire and a second set of grooves for guiding a second wire. The grooves of the first set alternate with grooves of the second set such that the circumferential surface of each drum is provided with multiple grooves of the first group, each interpositioned between two grooves of the second group. Therefore the traction winch is capable of cooperating with a first wire in the first set of grooves or with a second wire in the second set of grooves, wherein both wires differ in type of material and/or cross section and/or maximum tensile strength.

摘要： A shipboard winch having guide vanes includes a first drum and a second drum that are mounted on a frame so that the drums contra-rotate when the winch is activated. A plurality of guide vanes is positioned between the first drum and the second drum. Each guide vane is formed with a base and a distal lip that extends outwardly from the guide vane when the guide vane is oriented horizontally. The guide vanes are further formed with a decreasing taper from a maximum width at the base to a minimum width at the distal lip. For deployment/recovery, the cable is threaded around the first drum, through the guide vanes and around the second drum in a figure eight configuration. A feedback circuit is used to control the rotational torque of the drums to maintain a constant tension on a cable as it is deployed or retrieved.

摘要： A traction winch for a cable or the like includes a winch frame, at least two sheave assemblies each having at least a first sheave and a second sheave, each sheave having a single circumferential friction surface for the cable. The winch further includes at least two rotatable driveshafts, journalled in the winch frame in a side-by-side arrangement, each drive shaft being associated with a sheave assembly, and at least one motor for driving the driveshafts. The winch includes a differential assembly being provided between each driveshaft and sheave assembly so as to allow for different rotational speeds of the sheaves during operation of the traction winch due to cable elongation.

摘要： The invention concerns a so-called capstan winch (1) comprising drums (2, 3) driving a cable (C) and provided with a peripheral wall (22, 32) around which are strung independent peripheral rings (40–45, 50–55). Said rings are provided with a peripheral groove designed to receive the cable (C) and are made of an elastic material so as to allow both the cable (C) to be driven and a relative sliding movement between the peripheral rings (40–45, 50–55) and the peripheral wall (22, 32), the relative sliding movement being of amplitude substantially equal to longitudinal deformation of the cable (C), when it is subjected to tension stresses. The two drums (2, 3) can be axially offset relative to each other (p/2) and their axes of rotation (Δ1, Δ2), may form a non-null angle of inclination. The invention is particular applicable to deep sea oil exploration.

摘要： A detention unit is provided for retrieval of an elongated body (9), such as a cable. The unit includes two or more movable friction surfaces (1, 11) adapted to pull in the elongated body (9). The moveable friction surfaces (1, 11) are arranged relative to each other so that the elongated body (9) may bear or rest against at a part of at least two friction surfaces (1, 11) in a sequential manner. The part of the friction surfaces (1, 11) adapted to pull the elongated body (9) defines a arc section, and each friction surface is provided with a separate propulsion unit (3, 14).

摘要： A drive means for small portable ski lifts comprises a flanged motor-driven drive drum mounted at the upper station of the ski lift and frictionally driving an endless smooth rope adapted to be gripped by the skiers. The incoming reach of the rope passes around the drive drum in a first turn, then around an idle roller and finally in a second turn around the drive drum before leaving the drum. The drive drum is conical and the idle roller separated said turns is positioned radially outside the position on the circumference of the drum at which the incoming reach enters the drum and in approximately the same plane as the part of the conical drum having the smaller diameter.
