ABSTRACT:
This device is associated with a scaffolding suspended from at least two winches and is adapted to automatically control a safety mechanism when the scaffolding is inclined beyond a predetermined limit angle to the horizontal. The scaffolding is pivoted at each end to a stirrup rigid with the safety device which is suspended to the hoisting cable through a link. A push-member rigid with the scaffolding engages, when the scaffolding is inclined, a connecting rod which actuates a lever for clamping the jaws on a safety cable passing through the safety device.
