ABSTRACT:
An auxiliary safety support mechanism for an automotive hoist includes an elongated post having permanent magnets arranged at spaced points along its length. When the hoist is in its elevated position, the post can be manually inserted between the hoist platform and the floor surface, such that the post prevents the hoist platform from falling, due e.g. to malfunction of the hoist hydraulic system. The permanent magnets serve to detachably mount the post in a vertical position in which its axis is parallel to the piston axis.
