ABSTRACT:
A mechanism to be used on vehicles' chassis for lifting loads and including scissor-action means that are distensible by applying hydraulic force to its structural members. The mechanism includes a safety linkage assembly for connecting the piston rod of the hydraulic cylinder to the structural members that are pivotally mounted to the chassis. The linkage mechanism prevents slipping of the rod under drastic load changes.
