FIELD: agricultural engineering; lifting equipment. ^ SUBSTANCE: proposed crane-manipulator mounted on vehicle chassis 1 has column 6 with movable part 4 and fixed part 5, outriggers, boom 7, elbow 8, telescopic rod 9, load-gripping member 10 and their hydraulic drives. Crane-manipulator is furnished with hydraulic drives for vertical and horizontal displacement of load-gripping member. Outriggers are installed for reciprocating in vertical and horizontal planes. Control mechanism of outrigger horizontal displacement drive is made in form of pair of additional columns, and rods coupled by hinge joints into pairs and installed in tiers for connecting with main column and carrying plate installed from demounting of rear ends of vehicle frame sidemembers. Outriggers are arranged coaxially to vertical axes in lower hollow parts of columns. ^ EFFECT: increased load-carrying capacity, enlarged zone of servicing. ^ 13 cl, 14 dwg |
