LOAD INDICATOR FOR VEHICLE LIFT

摘要

An apparatus comprises a frame, a vehicle engagement assembly, a lift actuation assembly, a locking assembly, and an indicator system. The vehicle engagement assembly is designed to vertically lift a vehicle. The frame comprises at least one slot to provide a predetermined path for the vehicle engagement assembly. The lift assembly provides the force required to lift the vehicle while the locking assembly stabilizes the vehicles without further force required by the lift assembly. The indicator system determines whether the locking assembly or the lift assembly is predominantly keeping the vehicle lifted.
