Introduction of DWS25 Double Telescopic Suspension Hydraulic Prop For Mining Support
DWS25 Double Telescopic Suspension Hydraulic Prop using mine (suspension) technical principles, pillars suspension force to achieve four-fifths
of the working resistance, the column is only one fifth of the force. Thus greatly improving the pillars of stability and security, improve the supporting pillar height, carrying capacity and anti-bias load capability.
Application of DWS25 Double Telescopic Suspension Hydraulic Prop For Mining Support
DWB 25 double telescopic Suspension Hydraulic Prop for mining support is an emulsion or hydrostatic water as the working medium, as key parts (plunger, cylinder, base, return spring, etc.) with a leading anti-corrosion technology, there are certain acid and alkali resistance, suitable for different work environment for working resistance ≤ 30kN, the temporary support is brittle FRP materials which should be used to avoid the impact, supporting the use of three valves.
