Abstract
The invention includes a mechanic's creeper having a bowed frame and a method for constructing the frame. The frame comprises a pair of parallel longitudinal rails of rectangular metal tubing bowed to form an arch for increased strength against vertical loads resting on the creeper. A plurality of metal cross members are welded to the underside of the longitudinal rails to form the frame. A creeper bed formed by wood or metal sheet, a headrest and castors for movement are attached to the frame. To construct the creeper frame, the longitudinal rails are fixed parallel to each other and the cross members welded in a predetermined sequential order across the underside of the frame. The sequential welding causes the metal of the underside of the longitudinal rails to expand as it is heated and then to contract as it cools to a length less than its original length to bow the rails lengthwise.
