Abstract: A creeper has a base originally used for an engine hoist. The base has wheels for easy mobility. The base in its original form may look like an A-shape when viewed from above. Alternatively, the base is modified to accommodate a tilt front end vehicle like a tractor trailer truck. The height adjuster is an extendable/retractable device such as a hydraulic cylinder. A support beam connects the base to a platform. A vertical arm support, which is preferably metal, keeps the height adjuster in proper alignment for the range of movement of the platform. The platform has a frame. Although the frame can be any number of pieces, it is two pieces in this embodiment. The two pieces include a body section and a chest board section connected by a pivot plate. The entire platform can be folded down for easy storage. Each section is preferably padded with a body pad and a chest pad, respectively.

Abstract: A creeper has a base originally used for an engine hoist. The base has wheels for easy mobility. The base in its original form may look like an A-shape when viewed from above. Alternatively, the base is modified to accommodate a tilt front end vehicle like a tractor trailer truck. A height adjuster allows the creeper to be adjustable from approximately 32″ to 72″ with the level prone position at 50″. The height adjuster is an extendable/retractable device such as a hydraulic cylinder. Examples of types of height adjusters to be used include, but are not limited to, a hydraulic jack or a screw type device like a trailer tongue jack. A support beam connects the base to a platform. A vertical arm support, which is preferably metal, keeps the height adjuster in proper alignment for the range of movement of the platform. The platform has a frame. Although the frame can be any number of pieces, it is two pieces in this embodiment.
