Abstract

Conventional vehicle lifts typically operate at a standard speed that is statically configured for the system, which may result in vehicles that are below the weight rating for the lift being raised at the standard speed while the lift motor is capable of safely raising at greater speeds. A set of lift controls may be configured to determine the load on the motor by a vehicle of an unknown weight during operation at a standard lift speed and use such information to determine a potential speed that the motor may raise the vehicle at while staying within safe operational levels for the motor. One or more of a magnitude of electrical power drawn, a pressure generated by a hydraulic lifting, or a sensed vehicle weight may be used to provide an indication of load on the motor and/or a higher potential speed.
