Positioning the Stiff Leg
The illustration below is a side view of the one-lane parallel up-righting on a passenger car. The low pull; when used with the roll-over stiff leg, is extremely beneficial when up-righting a vehicle on any slippery surface, such as snow or ice.
The angle of the stiff leg, coupled with the compression load the leg places on the casualty, forces the vehicle to rotate with out sliding.
This is the traditional design and cut used for a roll-over stiff leg made of Schedule 80 PVC pipe. For many years since its introduction, it has been outstanding and an all around success, being an extremely versatile and useful tool in towing, transport and recovery industry.
