The bracket is one-sided movable side guard and a typical thin coal seam support, with an integral roof beam structure, a former single after double connecting rod, double balanced jack, moveable jack in full load.

The bracket adopts the fully functional 10-function electromagnetic reversing valve, which respectively achieves the functions of column lifting, balance stretching, closing and pushing , pulling and sideguard stretching, shrinking and automatic spraying. Scaffolds are equipped with electro-hydraulic control system, able to complete the bracket requires electrical control of the various action functions. The bracket can realize the automatic control of the group program, including the functions of automatic moving of the group in groups, automatic pushing of groups in a group and the like; and the manual and automatic operation of the adjacent frame electronic control and the manual operation of the solenoid valve button of the frame. Equipped with infrared emission and receiving devices, the bracket can be combined with the face of mining machine automatic action. The bracket can check the column working pressure, the route of the moveable jack, the location and direction of the shearer, and can also transmit the data to the underground electro-hydraulic control host and will be displayed.
