Introduction:

Double telescopic suspension hydraulic prop use mine (suspension) technical principles, pillars suspended four-fifths of the resistance force reaches work, 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.

Product description :

1. 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.

2. Mine (suspension) hydraulic prop abandoned lengthened cylindrical, stigma, and pistons, no arc welds, no internal leakage, visual inspection with the naked eye, pillar when disclosed, may be 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.

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

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

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

6. Plunger using original heat treatment processing technology, improve product Artillery collapse, against mechanical damage and anti-bending ability, reducing the amount of maintenance pillars, improved product safety.
