A ratchet and cam buckle tensioning assembly or strap tensioner, interposed between a lashing strap tensioned by the ratchet buckle (101) and a lead strap tensioned by the cam buckle (102). The cam buckle housing (144) and the ratchet buckle frame member (104) are a unitary member, forming a single integrated tensioning assembly. Alternately, the cam buckle is permanently attached adjacent to the ratchet buckle. The cam buckle (102) includes a housing adapted to slidably receive the lead strap. The housing (144) has a pressure plate (152) with a first restraining surface, such as a friction surface, over which the lead strap slides. A pawl (158) is movably mounted, such as by pivoting, to the housing (144). The pawl (158) has a second restraining surface and is biased in an engaged position to restrain the lead strap between the first and second restraining surfaces so as to prevent movement of the lead strap in one or both directions. |
