A lifting cart apparatus for engaging and moving a vehicle body component includes a wheeled base frame with a lift for raising and lowering a support platform relative to the base frame. The support platform has a pair of support arms for supporting a vehicle body component. A stabilizer is coupled to the support platform for engagingly stabilizing the vehicle body component on the support platform.

A portable auto lift includes a plurality of vehicle engaging arms configured to selectively engage and support a vehicle, a frame coupled to and supporting the plurality of vehicle engaging arms a moveable carriage coupled to and supporting the frame and the plurality of vehicle engaging arms; a vertical support post configured to receive the movable carriage that supports frame and the vehicle engaging arms, the vertical support post further including a vertically adjustable portion for selectively vertically adjusting the height of the vertical support post; and a hydraulic system for selectively moving the moveable carriage along a length of the vertical post, including selectively moving the carriage along a length of the vertically adjustable portion. The vertically adjustable portion maybe pivoted, removable, or telescoping.

Techniques are disclosed for methods and systems for automating the operation of a rolling-jack system for the servicing of automotive vehicles. The rolling-jack(s) travel/transport between the runways of a drive-on lift. They have automated/motorized transportation, engagement and jacking power mechanisms. These mechanisms are controlled by a guidance system which guides/controls them for a fully automated operation. A number of technologies may be used for this purpose, including sensors onboard the vehicles and/or the drive-on lifts and/or the rolling-jacks and/or the service center. A computer vision pipeline may also be utilized to assist in the process. Machine learning may also be employed. Techniques are also extended to autonomous vehicles as well as interfacing with fleet management software.
