Abstract
An hydraulically operated vehicle lift having an electro-hydraulic power unit mounted on one of the lift columns for supplying fluid to the hydraulic actuator for raising the lift carriages. The electro-hydraulic power unit has an electrical junction box mounted on the motor and a manually operable switch and a lift limit control switch mounted on the junction box and electrically connected inside the box to each other and to the motor windings. The lift limit control switch is actuated by a flexible switch actuating line that has a portion extending crosswise between the lift columns at a level to be engaged by the roof of a vehicle being raised, to stop the power unit.
