摘要： A device for pulling an elongate member includes a rotational motor having an output and a rotating drum connected to the output of said rotational motor. The device further includes a guide mechanism for guiding the resilient elongate element onto, around at least a portion of the circumference of, and off of, the rotating drum. When the rotational motor turns the rotating drum, the rotating drum thereby continuously pulls the resilient elongate element through the device.

摘要： An electrically powered hoisting system is operated by seating a line attached to the load to be hoisted in a groove formed between two sheave components and activating the electrical drive motor to rotate the sheave assembly. Voltage for the electrical drive motor is provided by an on-board 12 volt battery and voltage to the drive motor is controlled by means of a switch device. The groove formed by the sheave components has a resilient gripping surface that provides a firm line gripping action and hands-free and self-tailing operation. A davit, davit mounting brackets, and a flexible mounting assembly for mounting the powerhead assembly to a support are also disclosed.

摘要： A safety apparatus is capable of tensioning a horizontal lifeline while providing an adjustable shock absorber and a gauge or indicator for indicating the amount of tension on the lifeline. A housing is adapted to be secured to an anchor point through an anchoring line. The free end of a horizontal lifeline passes over a pulley within the housing and around a number of rollers which are adapted to maintain the lifeline in secure contact with the pulley. A lever is utilized to rotate the pulley in order to tension the lifeline. The lever, however, is interconnected to the pulley through an adjustable disk brake which can be preset to a desired force. When the tension on the lifeline reaches its desired level, the brake slips and the lever can freely rotate. A second series of disk brakes connected to the pulley function as a shock absorber. In the event of a fall, the initial force on the horizontal lifeline exceeds the braking force of the shock absorber brakes and the pulley can rotate through a limited number of turns. Eventually, however, the shock absorber brake slows the fall and eventually stops the same. The amount of tension on the shock absorber brake can also be adjusted to thereby control the amount of shock being absorbed. An additional brake mechanism prevents the lifeline from freely being drawn from the housing in the event of a complete failure of the mechanism thereof.

摘要翻译： 安全装置能够张紧水平救生索，同时提供可调节的减震器和用于指示生命线上的张力的量规或指示器。 壳体适于通过锚固线固定到锚点上。 水平救生索的自由端穿过壳体内的皮带轮，并绕过多个辊子，这些辊子适于将救生绳保持与皮带轮牢固接触。 杠杆用于旋转皮带轮以拉紧生命线。 然而，杠杆通过可调节的盘式制动器与滑轮相互连接，可调节盘式制动器可预设为所需的力。 当救生绳上的张力达到所需水平时，制动器滑动并且杆可以自由旋转。 连接到滑轮的第二系列盘式制动器用作减震器。 在跌倒的情况下，水平救生索上的初始力超过减震器制动器的制动力，并且滑轮可以旋转有限的匝数。 然而，最终，减震器制动器会减慢跌倒并最终停止。 还可以调节减震器制动器上的张力量，从而控制吸收的冲击量。 在其机构完全失效的情况下，附加制动机构防止救生索自由地从壳体中被拉出。

摘要： A single sheave 4 rope winch 1 particularly suitable for use with an anchor warp 2. The sheave 4 is fixed on a shaft 5 rotatably mounted in a base 3 adapted for mounting on a deck of a vessel. An electric motor 6 operates through a gear-drive 7 to rotate the sheave 4 about a vertical axis. Warp feed-in and feed-out means 8 and 9 direct a warp 2 to and from the sheave 4. Warp guide means 19 control a warp 2 during its tracking about with or through the sheave 4, the guide means 19 including a fixed and shorter section 19a and a longer articulated arm 27 section 19b. The arm 27 is arcuately shaped to extend about a sector of the sheave 4 and is biased by spring 26 radially inward such that an inner face 24 thereof impinges onto a warp 4 tracking in that sector of the sheave 4. In a preferred embodiment the inner impinging face 24 of the arm 27 incorporates a compound curvature, the radius of curvature increasing toward a free end of the arm 27.

摘要： A which winch can permit free-fall is disclosed, which includes a shaft adapted to be driven by a source of power, a first cone connected about the shaft to be driven therewith, and a second cone co-axial with the first cone and movable axially relative thereto. The second cone can be caused to assume one of two axial positions relative to the first cone, the arrangement being such that a rope or chain passing between the two cones can be driven by the winch when the second cone is in one of its two positions and can free-fall when the second cone is in the other of its two positions.
