Hydraulic Roof Support

Properties of product This series of products are a kind of hydraulic power unit which use liquid pressure to generate holding power and achieve automatic move for roof support and management. They are indispensable for the comprehensive mechanization coal mining. Mainly used in supporting working face top coal, to cover coal mining machine and front, back conveyors working space, in order to make coal mining machine once mine working face height, and transported by the front conveyor. And put caving of top coal on the back conveyor to transport out of the working face through located at the end of the beam Flashboard. Respectively through the cutting of coal, shifting planes, forward slip, caving, pull away back etc processes to compose operating cycle, and achieve continuous operation of comprehensive mechanization.
