Abstract
A cribbing apparatus for stabilizing a post-accident vehicle against unwanted movement of the vehicle during a rescue operation in which a victim trapped in the vehicle is to be extricated from the vehicle including a cribbing block having a two cribbing block portions, one of which is vertically movable with respect to the second in order to fill a space between the vehicle and the ground. The cribbing block includes a stair-stepped upper surface to facilitate the placement of the cribbing beneath vehicles of various ground clearances. The first cribbing block portion is raised to further fill space between the vehicle and the ground on high clearance vehicles, such as SUVs, Trucks and Buses. The structure and operation of the cribbing apparatus eliminates the need to forcefully jam cribbing into place between the vehicle and the ground and eliminates the need to stack cribbing.
