ABSTRACT:
An accident rescue tool is disclosed having a base, a base arm fixedly attached to the base, and a lifting arm pivotably attached to the base. In addition, means for pivoting the lifting arm toward the base arm is provided, as is a first chain connected to the base arm at one end and a rigid vehicle component at the other end and a second chain connected to the lifting arm at one end and a vehicle component at the second end. The pivoting means is connected to both the base arm and lifting arm to pivot the lifting arm so that the second chain causes the vehicle component to move in conjunction herewith.
