ABSTRACT:
A wrecker for towing disabled automobiles and the like has attachment fittings on the rear bumper each for securing a scotch block chain and a snatch block to the bumper at the same location on the bumper. When an automobile is being winched into towing position, buckling forces exerted on the bumper by tension developed in the scotch block chains are counterbalanced by forces exerted on the bumper by tension developed in the winching cable which is passed around pulleys on the snatch blocks.
