Winch for cargo-retaining strap

摘要

A winch for a cargo restraining strap includes a frame having a base and first and second parallel spaced sidewalls. The first and second sidewalls define respective first and second apertures. A protective wall extends from the base and is spaced from the first sidewall. The first sidewall and the protective wall cooperate to define a clevis structure including a channel. A pawl is movably secured to the frame, with an inner end thereof located in the clevis channel. A spool extends between the first and second sidewalls and is rotatably supported in the first and second apertures of the first and second sidewalls. A ratchet wheel is connected to the spool and is located adjacent the first sidewall. The ratchet wheel is selectively engaged by the pawl. The frame, spool and ratchet wheel can be defined from aluminum alloy. The frame can be extruded as a one-piece construction. The spool and ratchet wheel can be extruded as a one-piece construction.
