Abstract
The invention provides a movable one-post lift used for maintenance of a vehicle including: a base with transport wheels which are drawn up to and taken out of the base; an upright support post mounted on the rear end of the base; a driving mechanism disposed in the support post; a cantilever beam ascending and descending along the support post by the driving mechanism; a pair of parallel drive-on-plates fixed to the cantilever beam for supporting the body of the vehicle; and a stopper attached to a suitable position of the base for fixing the base at a predetermined location on the floor. This structure allows efficient car maintenance in a limited space as well as smooth transport and space-saving storage of the lift. The lift also includes riding plates which are connected to both ends of the drive-on-plate and pivotally moved downward when the drive-on-plate is lifted up from the floor level. This mechanism ensures an effective length of the drive-on-plate sufficient for securely supporting the body of a vehicle without preventing smooth detachment of wheels from the body.
