HOISTING GEAR

摘要

FIELD: hoisting gears; cargo handling. SUBSTANCE: hoisting gear mounted on self-propelled chassis includes cargo gripping and hoisting mechanism, drive for their motion and turn in horizontal and vertical planes and hydraulic system for control of these mechanisms. Hoisting mechanism is made in form frame and is mounted on chassis turned in turned in vertical plane by means of drive; carriage with gripping mechanism moves over guides; gripping mechanism has base and suspension articulated with this base; suspension is turnable in horizontal plane. Hoisting gear includes also support which may reciprocated along suspension by means of guide rigidly secured on axle box for cross-piece which is provided with lever articulated with turning drive. Mounted on cross-piece as cantilever are slide blocks interconnected by of rod and two grips made as mirror image in form sliding supports rigidly connected with surfaces of grip provided with supporting and drive rollers. EFFECT: possibility of using hoisting gear in hard-to-get-at areas. 3 cl, 6 dwg
