<p>A strap winch device assembly (34) for fitting on a flat bed open truck trailer (20), to enable a truck driver to remote actuate this load tightening system without leaving his truck cab, in periodic fashion. A number of these winch devices (34) are connected to a single fore and aft drive shaft (36), which extends along the side of the trailer. The drive shaft (36) is driven by a motor (38) to tighten any straps (5) that loosen when the trailer is in motion over the road, as trailer load distribution typically shifts during road trailer, due to road-induced vibrations. A clutch mechanism (62) is provided in the winch device, to prevent the motor from overheating once a set tightening torque thershold level has been reached. A manual override clutch system (80) is provided, to enable an operator to release the tensioning of the winch device whenener needed.</p> |
