MANIPULATOR Russian patent published in 2001 - IPC

FIELD: agricultural engineering; material lifting and handling facilities. SUBSTANCE: proposed manipulator has base 1 in form of hollow cylinder with inclined upper beam, lower beams with telescopic supports and locks and with mount brackets 2, 3, 4, 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 plane of base and is connected with base by slewing mechanism. Base of one of slewing mechanism hydraulic drives is hinge-coupled with upper end of upper beam. Extreme ends of lower beams are orientated downwards and those of upper beam, upwards, its projection being located in the middle between lower. EFFECT: reduced dynamic loads, simplified design, enlarged zone of servicing. 11 cl, 2 dwg
