Abstract

A vehicle leveler which includes a first portion with a leading edge and a trailing edge, the trailing edge is disposed further from the driveway than the leading edge. The leveler also includes a second portion with a leading edge and a trailing edge, the leading edge of the second portion is disposed further from the driveway than the trailing edge of the second portion. The vehicle leveler has a door interlock system with at least one pair of photoelectric sensors with a sensor path. When a vehicle is being loaded or unloaded on the vehicle leveler, and at least one of the vehicle doors is opened, the door blocks the sensor path of the photoelectric sensors and prevents the vehicle leveler from lowering or raising.
