FIELD: mechanical engineering; hydraulically controlled manipulators for timber, transportation, building, load lifting and other machines. SUBSTANCE: telescopic device has support and movable sections, section movement mechanism with drive from hydraulic cylinders, working member installed on end of device. Section movement mechanism has two kinematically series connected hydraulic cylinders hinge-secured by some ends on support and inner sections and by other ends, hinge inter connected by common axle and connected with support rollers placed in rigid guides. Housing of one of hydraulic cylinders is hinge connected with middle section. EFFECT: increased reliability, reduced overall dimensions and materials usage. |
