Abstract
A creeper for use by mechanics and inspectors has a platform for supporting the user and a pair of roller elements astride the user's head at one end and roller element between the user's legs at the other end. The single roller element is in a mounting system which supports the creeper a preselected distance above ground on a spring biasing system which can be overcome by increasing the weight on the platform near the system so that the platform will lower into contact with the floor.
