Mining Hydraulic Prop 

Single Hydraulic prop is a kind of new environmental protection supporting equipment, it can be matched with metal articulated roof beam used in high-grade conventional and blasting face supporting the roof and the fully mechanized working face support end also can do some column or other temporary support.

Our Coal Mining Painted Adjustable Hydraulic Scaffolding Props with metal hinged roof beams for general mechanized coal mining face gun and mechanized mining face ends with a roof or temporary payment for coal seam angle is less than 25 ° of face, to take certain measures, also can be used to dip 25 ° – 35 ° stopes. This series of hydraulic prop, good stability, technical performance advantages prominent, high-grade coal mining face will be the single support height from 2.5 meters to 3.5 meters, 3.5 meters below the coal mining can achieve one full-height, while for the coal seam thickness of 4.5 m below provides end face and advance support

Coal Mining Painted Adjustable Hydraulic Scaffolding Props Characteristic

1, Long working stroke, especially for large height variation face of the underground roof.

2, Apply inner bore seal bump- resistance in the underground, with a wide range of use.

3, Never broken. Using friction welding, the weld is not broken.

4, Uses a new sealing device, remove the DZ-type pillar between the piston and plunger leakage point, safe and reliable
