DW single hydraulic prop,coal mining support machine
Description
DW single hydraulic prop is constant resistive pillar, which can match with a variety of roof
beams and also could be used as the primary column. Mechanized coal mining for coal
generally or blasting mining face plate supporting items are also available for mechanized coal
face end support or other temporary support to use.
Applicance
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.
Feature
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.
5,Level of support available.
6, High strength, no bend.
