The present invention relates to the field of device calibration technologies and discloses a sliding apparatus and an automobile calibration device. The sliding apparatus includes: a guide rail, which includes a first surface and a second surface that are perpendicular to each other, where the first surface is provided with a first sliding groove and the second surface is provided with a second sliding groove, the first sliding groove and the second sliding groove being disposed in parallel; and a plate body, a first sliding member and a second sliding member, where the first sliding member and the second sliding member are installed on the plate body. The first sliding member is movably installed in the first sliding groove and the second sliding member is movably installed in the second sliding groove, so that the plate body is slidable along the guide rail. By using the above technical solutions, embodiments of the present invention can ensure parallelism of the plate body and the guide rail, so that the sliding apparatus can slide smoothly even in a status with a relatively large load.

A floor protection apparatus for use under parked snowmobiles or the like. The apparatus features a mat having longitudinally opposing first and second ends, and laterally opposing first and second sides. Longitudinally channeled areas reside respectively adjacent the sides of the mat at a topside thereof, and each feature a set of longitudinally running channels separated from one another by longitudinal ribs. One or more collection areas reside between the channeled areas at the topside of the mat and are of recessed elevation relative to the longitudinal ribs. A laterally ribbed central area resides between the first and second channeled areas and comprising a series of lateral ribs spaced from one another in the longitudinal direction. The mat is assembled from sections that fastened together through raised, abutted boundary edges.

Systems for inspecting and servicing a tire assembly are provided. In one embodiment, a tire assembly service cart is provided that includes a tire assembly support structure. The tire assembly support structure may include a side support member that is positioned to support a side of the tire assembly. The tire assembly support structure may also include a first bottom support member positioned to support a bottom portion of the tire assembly. The side support member may include a first roller and the first bottom support member may include a second roller. Further, the first and second rollers may be positioned to allow the tire assembly to rotate around a rotation axis while supported by the tire assembly support structure.

A technician's work chair having a frame, an air cushion assembly, a seat assembly, and air hose and a pivoting hose support. The air cushion assembly is attached to the frame and supports the frame on an air cushion formed above a floor surface. The seat assembly has a cushion portion on the frame and a seatback portion with a mechanism that changes an angle of inclination of the seatback portion. A technician seated in the seat assembly can ergonomically operate tools and complete tasks with arms raised over the technician's head. The air hose having a first end connected to a compressed air source and a second end connected to the air cushion assembly. The pivoting hose support biases the air hose to move in a rearward direction relative to the technician's work chair.

A wheel detailing stand that provides for 3-point contact with a wheel mounted thereon is disclosed. The wheel detailing stand includes a base frame having a bottom frame member and a back frame member extending upwardly from the bottom frame member, a pair of bottom rollers attached to the bottom frame member where the pair of rollers are arranged in parallel and spaced apart from one another, and a back roller attached to the back frame member and oriented generally orthogonally to the pair of bottom rollers. The pair of bottom rollers and the back roller provide 3-point contact with a wheel positioned on the wheel detailing stand.

An apparatus which enables a person to comfortable work on the engine of a vehicle includes base, spine, post, knee pad, and chest pad components. The spine component is pivotally connected to the base component. A brace prevents the pivoting movement but is removably connected between the spine and the base to allow pivoting when desired. The spine component carries the tube component at a selected height, and the tube component carries the knee pad component at a selected position. The tube component carries the chest pad component.
