Abstract

The present invention is a lifting mechanism with lift stand accommodation, which is used to allow a lift stand to reside within its bounding space. The present invention comprises a lifting mechanism and a Y-shaped chassis. The Y-shaped chassis comprises a lift mechanism housing and a U-shaped base. The U-shaped base comprises a base slot that allows a jack stand frame to be inserted between its left and right end. The lifting mechanism is used to raise and lower an object from its initial position. The lifting mechanism comprises a left support arm, a right support arm, a lift arm and a U-shaped lift platform. The U-shaped platform comprises a platform slot that can allow a jack stand saddle to be inserted between its left platform end and right platform end. A brace maintains the rigidity of the lift arm, the left support arm, and the right support arm.
