The Auto Crib-It from Power Hawk allows stabilization of vehicles and objects in seconds.  Auto Crib-It uses a piston-actuated system that allows it to be placed under a vehicle or object and "tripped" into position providing almost instant stabilization. 

During lifting operations such as air bags, rescue struts, or hydraulic spreaders Auto Crib-It also automatically extends and re-locks at the new height.  This ensures there is never a "gap" in stabilization, eliminating the need for a rescuer to reach under the load to adjust manually.
