Braking device for the charges litters by a support pylon, the pylon on illumination associated with using this device

摘要

When the tension in a cable (6) supporting a weight such as a candelabra on a pylon disappears a spring loaded arm (17) pushes jaw plates (8a,8b) upwards. The jaws have angled slots (12a,12b) which enclose fixed shaft ends and they therefor are forced together to grip a guide rail (9). Any tendency for the jaws to fall causes them to grip more firmly and a dedicated release element is provided An Independent claim is made for a pylon using the braking system
