ABSTRACT:
A dual-column vehicle lift having first and second lift columns, each with carriages slidably mounted thereon, and each with piggy-backed hydraulic lift cylinders. The piston rods of each column's piggy-backed lift cylinders extend in opposite directions, one attached to the carriage and the other attached to the base of the lift column. The piggy-backed construction allows a lower collapsed height of the cylinders and also allows a lower lift column height for a given lifting height, thereby allowing use within an area with reduced ceiling clearance. An interconnection tube equalizes hydraulic pressure between the piggy-backed lift cylinders, causing the two cylinders to extend their rods at the same rate. Equalizing cables are provided for ensuring that the carriages on the two lift columns rise and fall together.
