ABSTRACT:
A trailerable, mobile motor vehicle service unit is especially equipped to realign wheels and axles of a motor vehicle driven onto the unit. The unit provides a track on which a motor vehicle is driven and a track ramp portion that can be lowered to the ground to facilitate loading of a motor vehicle. Once loaded the ramp is once again raised to a horizontal position. The unit is lifted from its wheels by 4 fixed-length support legs positioned under the wheel position of the loaded motor vehicle which pivot by action of hydraulic cylinders which draw the respective legs to or extend them from the unit. The unit may also be lowered to the ground by first hydraulically relocating its wheels mounted on a slidable axle frame into a wheel storage area of the unit body frame before lowering the unit on its support legs. The unit also is provided with a longitudinally relocatable hoist mounted between track 16 and 16' and with transversely-adjustable primary and secondary wheel alignment pads, respectively located forward in the tracks and over the forward support legs in the normal position of the motor vehicle front wheels and on extension braces forward of the tracks to accommodate long vehicles.
