FIELD: mining, particularly to mount sections of powered support and other equipment. ^ SUBSTANCE: mounting facility comprises base, gripper pad with hydraulic prop, column rotation jacks, boom and hydraulic cylinders for boom lifting. Rotary column is installed on the base so that rotary column may perform rotation movement. The rotary column is made as pipe provided with sprocket. Column rotation jacks are secured to upper plane of the base. One boom end is connected to rotary column. End boom with load gripping mechanism is fastened to another boom end. The boom is additionally connected with rotary column by hydraulic cylinders for boom lifting. Hydraulic prop of gripper pad is pinned to lower support part near base and is located inside rotary column. Sprocket engages two racks of column rotary jacks provided with double-sided rods. Lower sprocket end and cylindrical groove on upper support surface form lower thrust-radial friction bearing. Mounting facility is provided with gantry connected to the base and composed of two parts. The gantry parts are connected one to another by cylindrical bridge and provided with semi-rings, which enclose bored upper pipe part and form upper friction bearing for rotary column. ^ EFFECT: increased efficiency of mounting facility operation. ^ 2 cl, 3 dwg |
