Open Type Hydrulic Prop

DW series open type hydraulic prop is normally used for the roof support of coal mining face independently or associated with slide bar or articulated steel beam. It is suitable for gently inclined seam with a gradient less than 25 degree. If safe measuresa are taken, it also can be used for coal face with gradient up to 25-35 degree. Besides, it also could be used as end support in fully mechanized coal mining face. While it needs pump station to supply the emulsion to work, this is the difference from DN series hydraulic prop.

Features:

Reliable performance, convenient and safe to operate, and low maintenance cost.
