Product Description
Profile
DW single hydraulic propis constant resistive pillar, which can match with a variety of roof beams andalso could be used as the primary column. Mechanized coal mining for coalgenerally or blasting mining face plate supporting items are also available formechanized coal face end support or other temporary support to use.
DW single hydraulic propwith metal hinged roof beams for general mechanized coal mining face gun andmechanized mining face ends with a roof or temporary payment for coal seamangle is less than 25 ° of face, to take certain measures, also can be used todip 25 ° - 35 ° stopes. This series of hydraulic prop, good stability,technical performance advantages prominent, high-grade coal mining face will bethe single support height from 2.5 meters to 3.5 meters, 3.5 meters below thecoal mining can achieve one full-height, while for the coal seam thickness of 4.5 m below provides end face and advancesupport.
Characteristic
1, Long working stroke ,especially for large height variation face of underground roof.
2, Apply inner bore sealbump- resistance in the underground, with a wide range of use.
3, Never broken. Using frictionwelding, the weld is not broken.
4, Uses a new sealingdevice, remove the DZ-type pillar between the piston and plunger leakage point,safe and reliable.
5,Level of supportavailable.
6, High strength, no bend.
