Double telescopic suspension hydraulic prop

Double telescopicsuspension hydraulic prop

using mine (suspension) technical principles, pillarssuspension force to achieve four-fifths of the working resistance, the columnis only one fifth of the force. Thus greatly improving the pillars of stabilityand security, improve the supporting pillar height, carrying capacity andanti-bias load capability.

Mine (suspension) hydraulic prop abandoned lengthened cylindrical,stigma, and pistons, no arc welds, no internal leakage, visual inspection withthe naked eye, pillar when disclosed, may be replaced at any pillars that propsafer avoid the pillar caused by the presence of leaks inside the pillar topand cumbersome virtual testing work.

Mine (suspension) hydraulic prop three valves designed tohandle body, the liquid injection valve is not used when the three plungerrises with increase of pillar working stroke, a specification alternative DZStrut 2-4 specifications, ease of management and use of the underground scene,reducing the labor intensity of the miners.

Mine (suspension) hydraulic prop each seal pointcompensation and sealed up tight technologies seal replacement is veryconvenient, simple maintenance, assembly and disassembly, simply replace thedamaged parts.

Mine (suspension) hydraulic prop used nickel - phosphorus- boron plating surface treatment, corrosion, wear resistance, can be used as aworking medium neutral water underground is environmentally friendly pillardevices.

Plunger using original heat treatment processingtechnology, improve product Artillery collapse, against mechanical damage andanti-bending ability, reducing the amount of maintenance pillars, improvedproduct safety.
