Abstract

Emergency brake and safety immobilizing device for mobile platforms for lighting towers or the like, characterized in that there are distributed on the said platform at least three boxes having guide means for the horizontal radial movement of respective arms each fitted with pressure shoes for pressing against the tower, which arms are pushed by spring means towards the tower and attached to the ends of respective hoisting cables, which when under tension draw the shoes back from the tower during the movements of the platform, fast-acting arm locking means being provided to lock the arms towards the tower when the hoisting rope is not under load. <IMAGE>
