FIELD: cargo hoisting equipment; trees felling, packaging and logging. ^ SUBSTANCE: proposed manipulator includes swivel column mounted on base and provided with mechanism for turning it relative to vertical axis; boom and its turning mechanism is mounted on this column; boom turning mechanism used for turning the boom in vertical plane is provided with power member and flexible rod. Articulated on free end of boom is handle with working member and drive. Power member of boom turning mechanism is made in form of winch in vertical plane which is mounted on frame of self-propelled chassis, or on swivel column, or on base. One end of flexible rod is connected with boom and other end is passed through guide block mounted on upper end of swivel column; flexible rod is wound around the winch drum in several turns; guide block is mounted on swivel turn below axis of attachment of boom to swivel column. Upper point of guide blocks are located at equal distances from axis of attachment of boom and points of attachment of flexible rod ends to the boom are also located at equal distances from axis of attachment of boom to swivel column. ^ EFFECT: reduction of dynamic loads; enhanced reliability of handle and boom; unification of handle and boom drives. ^ 3 cl, 4 dwg |
