Vehicle elevating apparatus and method of assembly thereof

摘要

A vehicle elevating apparatus constructed with a pair of independent runway carrying parallelogram assemblies each being provided with raising and lowering motor of pressure fluid type, and a torsionally stiff component operatively connecting the parallelogram assemblies so that in the event of failure of one of the motors the torsionally stiff component will transfer the load and substantially equalize the position of the runways and prevent a catastrophic accident.
