for temporary roof supporting in the lane, especially when carrying out lane maintenance and road heading.
1.constant resistance prop with hydraulic oil supply outside.
2. nonmetallic material to make it portable, erosion resisted and easy to operate.
3. emulsion or static pressure water as the medium.
4.for various working environment.
All the key parts (movable prop, cylinder, pedestal, reset spring, etc.) adopt advanced erosion resisted technology and can resist acid and alkali corrasion
5.lignt weight
Its weight is only 40% of steel prop with same height, it reduces the labor intensity and improve working efficiency.
