double telescopic suspension single hydraulic prop feature

1、 On the principle of mine (suspension) technology, pillar levitation force reached four 5 of the working resistance, the stress of the columns is only one 5. Pillar stability and safety, can be enhanced greatly improved the pillar support height, carrying capacity and partial load resistance.

2、Mine (suspension) individual hydraulic prop abandoned the extended column barrel, stigma and the pistons, no arc weld, no inner leak, visual inspection with the naked eye, prop once leaks, pillar can change at any time, make pillar more safety, avoid the pillar pillar of virtual due to exist within the leak and troublesome work.

3、Mine (suspension) of individual hydraulic prop with three valve design in hand on the body, when the filler with three valve is not increased with live column, increased the working stroke pillar, a specification alternative pillar 2 ~ 4 DZ type specification, easy to mine site management and use, reduce the labor intensity of the miners.

4、Mining (suspension) individual hydraulic prop the sealing point of the compensation and when tight seal technology, seal replacement is very convenient, simple installation and maintenance, only need to replace the damaged parts.

5、Mine (suspension) individual hydraulic prop used ni - p - boron chemical plating surface treatment technology, anti-corrosion, high resistance to wear, available neutral underground water as working medium, the pillar is environmental protection equipment.

6、Live column USES the original heat treatment process, improve the product's artillery collapse, prevent mechanical damage and bending resistance, reduce the amount of maintenance of the pillar, improved the security of the products.
