The present invention relates generally to securing devices, more specifically but not by way of limitation, an apparatus that is configured to engage a winch on a flatbed trailer wherein the apparatus facilitates operation of the winch so as to secure a strap over a cargo load.
Millions of tractor trailers traverse the roads everyday carrying various types of cargo to their destination. There are different types of trailers that are utilized to transport the alternate types of cargo. Palletized loads, boxes and similar types of cargo are most often carried in conventional box trailers that are completely enclosed. Another type of frequently utilized trailer is a flatbed trailer. These types of trailers are utilized for materials that cannot be palletized such as but not limited to lumber and pipe. The flatbed trailer is configured to receive the load superposed on the upper surface and the load is subsequently secured thereto.
One issue with securing cargo to a flatbed trailer is the utilization of straps. Most flatbed trailers have deployed along the sides thereof nylon strap rolls and winches on the opposing side. The straps are configured to extend over the load and be operably coupled with the winch wherein the winch is utilized to tighten the strap across the load so as to secure the load in place. The conventional winches coupled to flatbed trailers have a shaft that extends outward from the mounting bracket. The portion of the shaft that extends beyond the mounting bracket has apertures journaled therethrough. These apertures are utilized to place a bar or similar device to rotate the shaft so as to facilitate the tightening of the strap across the load. One problem with operation of the winch with a bar is the increased time required as constant removal/re-insertion of the bar is required during the strap tightening process. Range of motion of the bar can be limited by structure of the trailer and further can cause injury during the strap tightening process.
It is intended within the scope of the present invention to provide a winch engagement apparatus that is configured to engage the shaft portion of the winch of a flatbed trailer wherein the present invention facilitates the operation thereof with reduced time and opposing rotational capabilities.
