Description

DN Series Close Type Hydraulic Prop

DN Series Close 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.



Features:

1.Light weight, easy and convenient to operate, and no need emulsion supply.

2.Reliable in sealing, and fast to set up and easy to retract.

3.No emulsion drainage while retracting, so it keeps a clean working condtion.
