The hydraulic scaffolding is made up of those parts
Carrying member: roof beam, cover beam, base etc. The top beam and the roof are directly exposed to the pressure of the rock on the top. Covering the beam, preventing the falling rock from entering the working face, and bearing the pressure of the top level thrust. Base contact with floor board, transfer and withstand roof pressure.
Actuator: various jacks and columns. Column is supported between the cap and base or indirectly under the roof load cylinder, the hydraulic support is the main dynamic behavior of the components, its structural strength and form determines the size of the support bracket and support scope. Jack is a kind of oil cylinder (except column of column), it completes and adjusts the various protection action.
Ancillary device: all the above three components, the rest are auxiliary devices. Including the device, the copying device, the protection, the anti-pouring device, the spray lighting and so on.
Control and control components: control valves for valves, isolation valves and other oil cylinders. The control valve is a valve that controls the various movements of the scaffold, which is the conductor of the hydraulic support.
