ABSTRACT:
An automotive lift device of the type having a bed plate with laterally swingable arms which are adapted to swing outwardly for engagement beneath the vehicle frame is provided with a freely rotatable lever associated with each arm. When the bed plate is in the lowered position, the arms are forced to lie in horizontal attitudes in which the arms are free to clear them. A shiftable weight associated with each lever causes that end thereof which underlies the outwardly swung arm to rotate downwardly and project below the bed plate when the bed plate is elevated and each end of each arm is provided with a striker such that when the bed plate is again lowered, that end of the lever which has rotated downwardly will strike the support surface and cause the lever to continue in its initial direction of rotation so that the opposite or upstanding end of the lever will engage against its respective arm and will swing it back to its initial position whereby the arms are automatically returned to positions in which the vehicle can be driven away without striking the lift arms.
