Abstract
A cable lift includes a platform supported on posts and raised and lowered by cables. Yoke ends support the platform on the posts by means of dogs which project into openings in latch plates on said posts. The dogs are retracted in order to lower the platform. In the event of a slack cable condition, a slack cable actuator moves the dogs back into contact with the latch plates.
