An indispensable support tool in mining and coal mine tunnels is Single hydraulic prop, single hydraulic prop is divided into internal injection type and external injection type. External injection type also has suspended type and fiberglass type. Its specific functions and model parameters are described in the following questions
For details, please call ①②⑥⑦⑨①⑦< br/>The single hydraulic prop uses liquid pressure to generate working resistance and realizes column lifting and unloading. The single retractable prop is matched with metal hinged roof beams or long row beams of different specifications. It can be applied to any mining with coal seam inclination angle below In coal working faces with impact ground pressure, the pillars can be replaced with large-flow three-purpose valves to meet their support requirements
Single pillars can be divided into according to the height after elongation
, there are two types of cylinder diameters, please specify the requirements when ordering
The parameter models of some models, rated working resistance, rated working hydraulic pressure, initial support force, pump station hydraulic pressure, maximum height, minimum height, working stroke, cylinder diameter, Use working fluid, quality
