Double Telescopic Suspension Hydraulic Prop

Double telescopic suspension hydraulic prop

using mine (suspension)technical principles, pillars suspension force to achieve four-fifths of theworking resistance, the column is only one fifth of the force. Thus greatlyimproving the pillars of stability and security, improve the supporting pillarheight, carrying capacity and anti-bias load capability.

Mine (suspension)hydraulic prop abandoned lengthened cylindrical, stigma, and pistons, no arcwelds, no internal leakage, visual inspection with the naked eye, pillar whendisclosed, may be replaced at any pillars that prop safer avoid the pillarcaused by the presence of leaks inside the pillar top and cumbersome virtualtesting work.

Mine (suspension)hydraulic prop three valves designed to handle body, the liquid injection valveis not used when the three plunger rises with increase of pillar workingstroke, a specification alternative DZ Strut 2-4 specifications, ease ofmanagement and use of the underground scene, reducing the labor intensity ofthe miners.

Mine (suspension)hydraulic prop each seal point compensation and sealed up tight technologiesseal replacement is very convenient, simple maintenance, assembly anddisassembly, simply replace the damaged parts.

Mine (suspension)hydraulic prop used nickel - phosphorus - boron plating surface treatment,corrosion, wear resistance, can be used as a working medium neutral waterunderground is environmentally friendly pillar devices.

Plunger using originalheat treatment processing technology, improve product Artillery collapse,against mechanical damage and anti-bending ability, reducing the amount ofmaintenance pillars, improved product safety.
