Abstract
Abstract The improved trailer winch disclosed herein is adapted to be mounted on the channel side rail of a trailer and to be utilized to assist in securing loads to the deck of a trailer. The means for mounting the winch on the channel side rail of the trailer allows the winch to be slidably moved with respect to and along the channel side rail of the trailer so that the winch can be selectively positioned with respect to the load to be secured. The winch mounting means also prevents removal of the winch from the channel side rail of the trailer. The winch is constructed so that it does not project beyond the maximum permissible eight foot width clearance of the trailer and so that it may be operated by a person standing on the ground next to the trailer.
