ABSTRACT:
The present invention relates to a mobile lift or jack for elevating an object, especially an autombile, entirely from the floor. The lift is adapted engage the object from its side. It includes a base which comprises a power section and a floor stand. The floor stand is horizontally disposed and the power section includes a pair of upstanding braces. One end of the brace is attached to and extends upwardly from the base. The lift further includes a carriage with central support beams for holding the object. A main structural arm is disposed between the brace and the central support beams. One end of the main structural arm is pivotably attached to the central support beam at about the middle thereof and the other end of the connector arm is pivotably attached to the brace. Support arms are disposed between the central support beams and the brace. One end of the support arm is pivotably attached at a location distant from the middle of the central support beam and the other end is pivotably attached to the brace, whereby rotation of the carriage around the pivot between the brace and the central support beam is limited and the central support beam can be maintained on a horizontal plane. A hydraulic power supply disposed in the power section is used to lift the carriage by urging a piston rod against the main structural arm so that upon actuation of the power supply, the carriage can be elevated. The parallel beams are secured together by adjustable lateral support beams.
