Abstract

The apparatus for hoisting lighting fixtures onto a mast has a slide (10) which can be raised on a vertical rail (20) by means of a cable (28), a brake being available for arresting the slide (10) if the cable (28) snaps. In order to improve the service life of this apparatus compared with the known apparatus of this type, guide rollers (15, 17) are arranged on the slide (10) in the interior of a T-shaped groove of the rail (20). The brake blocks (22) of the brake device are likewise located in the groove of the rail (20), as is the cable (28) fastened to the brake lever (23) of the brake device.
