FIELD: power engineering; trolleys for moving over split-phase conductors of overhead power transmission lines.
SUBSTANCE: proposed trolley has form-structure framework that mounts hangers with rollers. Drive motor is disposed inside framework on floor panels and functions to move trolley over line conductors. Hangers are mounted for rotation about framework tube and for longitudinal movement along this tube. Hangers are also rotating about tube but they are rigidly fixed by means of brackets and spacer bushings to prevent their longitudinal displacement on tube. Hangers are made in the form of spring mechanism with rod rigidly fixed with roller and hinged by means of control rod and shackle with grip-lever turning in vertical plane. Brake mechanism has brake insert disposed on axle and acts on conductor in braking. Trolley is safeguarded by means of slings attached to spacer bushings near hangers by means of snap hooks.
EFFECT: easy control and simplified design of trolley affording provision for preventing any sliding of rollers off conductors and for trolley fixation at desired point whenever necessary.
