Applications

The loading and unloading of cargo is expedited by the use of this kit. It can be used to extend the standard winch cable and is employed whenever heavy loads are to be moved with a multiple purchase arrangement. In addition to pulling applications, the kit can be rigged to ‘push’ cargo packages, eliminating the need for cable attachment points or slings on cargo packages. Extracting and inserting cargo packages without cable attachment points that are surrounded on three sides, can also be easily achieved.
