摘要

The support for a mechanic working on the under side of an automobile (2), which has been lifted off the ground by a platform to give a working space (3), is a rolling trolley with a seat (9) and pref. a backrest (10) to support the mechanic. The seating (9,10) has a height adjustment on the rolling trolley (8) which can be steered. The adjustment to the seat height does not alter the position of the mechanic's body, where the mechanic uses a foot lever (12) to operate a hydraulic cylinder (11) which raises and lowers the seating (9,10).
