A tensioning apparatus for a cargo lashing strap that secures cargo to a cargo deck and is configured to have a frame having a first portion adapted to couple the frame to the cargo deck an intermediate portion, and a second portion. The frame has two side walls extending continuously therealong and are generally parallel to one another in the first and second portions, and taper in the intermediate portion. A spindle receives the cargo lashing strap and extends through apertures in the side walls in the second portion of the frame. The spindle is provided with an axial slot therethrough for engaging the cargo lashing strap. Ratchet wheels arranged on the first and second spindle ends, rotate with the spindle. An adapter facilitates engagement and disengagement of a torquing lever with the spindle. A pawl shaft has ends that extend through apertures in both side walls in the second portion of the frame. Pawls on the pawl shaft ends rotate with the pawl shaft between engaged and disengaged positions with respect to the ratchet wheel. The tensile force on the cargo lash must be overcome to achieve disengagement of the pawls and ratchet wheels. The pawls have integrally formed therewith respective manipulable handle portions for facilitating manipulated movement of the pawls between the engaged and disengaged positions. A biasing element applies a resilient force to the pawl shaft to urge the pawl toward the engaged position. Some embodiments are provided with a quick release arrangement for releasing quickly and conveniently the tensile force on the lashing strap.
