Abstract

The mechanism is particularly for vehicle lifts, and incorporates a brake automatically halting the lift cage when the control is moved to the stop position, or one of the cage drive chains slackens off. A feeler detecting a slack chain can be equipped with limit switches preventing lowering of the load on the cage jamming and the chains slackening off. Where the cage travels on a number of guide rails, the chain for each rail can have a cam-operated switch, the switches being connected in parallel. The cut off the current to the cage if the chain speeds differ.
