Product Description

Introduction of Suspension Type Double Telescopic Hydraulic Prop for Coal Mining

DWS25 Double Telescopic Suspension Hydraulic Acrow 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 Suspension Type Double Telescopic Hydraulic Prop for Coal Mining

DWS25 Double Telescopic Suspension Hydraulic Acrow Prop abandoned lengthened cylindrical, stigma, and pistons, no arc welds, no internal leakage, visual inspection

with the naked eye, pillar when disclosed, maybe replaced at any pillars that prop safer avoid the pillar caused by the presence of leaks inside the pillar top and

cumbersome virtual testing work.
