    摘要: Described are various embodiments of capstan drive transmission self-tensioning apparatus and method. In one embodiment, the capstan drive transmission self-tensioning apparatus comprises a body coupled to the capstan drive drum comprising a force providing member coupled to the cable and configured to displace the cable along a path increasing an effective distance between said first end and said second end of the cable thereby increasing a tension within said cable; a jamming assembly directly or indirectly coupled to said cable and configured to: allow motion of said cable along said path upon said tension being below a lower designated level; and prevent motion of said cable along an opposite path upon said tension being above an upper designated level. In some embodiments, the jamming assembly may comprise a spring-loaded rocker mechanism, a ratcheting mechanism or a directional frictional material to provide the jamming effect.

    摘要: A winch engagement apparatus that is configured to be operably coupled to a strap winch on a flatbed trailer wherein the present invention provides a technique to rotationally move the shaft on the strap winch so as to tighten a strap. The present invention includes a housing wherein the housing has a first side and a second side. A passage is present through the housing and extends between the first side and the second side having openings at each end thereof. The passage is configured to surroundably mount a portion of a shaft present on the strap winch. Engagement levers are present wherein the engagement levers are pivotally secured to the housing. The engagement levers includes a hole engagement edge that is operable to penetrate a hole formed on the shaft portion in order to operably lock the housing into position so a rotational force can be applied.

    摘要: The present disclosure relates to a portable device for hoisting/lowering/storing a rope from a tall structure, such as a wind turbine. The device is formed of an assembly of a rope storage container and a rope driver reversibly connected thereto. The rope storage container defines a rope storage volume bound between a bottom surface and an outer side wall. The rope driver is reversibly connectable to the container and comprises a rope passage having a dimension matching a diameter of the rope. The passage is formed between a pair of adjacent rollers or between a drive coil and a clamp. The rope is driven (hoisted and stored or provided and lowered) by an electric motor arranged to drive at least one of the rollers or the drive coil.
