DW 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 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.
