MANIPULATOR Russian patent published in 2001 - IPC

FIELD: agricultural engineering; load-lifting facilities. SUBSTANCE: proposed manipulator has base 1 in form of hollow cylinder with inclined upper beam, lower beams X-like orientated in horizontal plane and furnished with telescopic supports and mounting brackets 2, slewing column 9 with hinge-mounted boom 10, stick 11 with hinge-mounted load-gripping hook and boom, stick and slewing column control hydraulic drives. Slewing column is arranged coaxially in base space and is connected with base by slewing mechanism made in form of their-mounted single-arm lever 23 and double-arm lever 24 installed for free rotation on slewing column and additional lever 25 rigidly secured on slewing column. Ends of double- arm remote from axis of rotation are hinge-coupled with bases of hydraulic drives. Rod of one of hydraulic drives is coupled through hinge-joint with upper end of upper beam, and rod of other drive is connected with extreme end of freely rotating single-arm lever connected by third hydraulic drive with additional lever. EFFECT: enlarged zone of servicing, improved dynamic and mechanical characteristics. 3 dwg
