Hydraulic prop is a common support equipment in underground roadway, which is widely used. Do you know the advantages of hydraulic prop?
1. Acrow prop Large supporting force and anti eccentric load
Using the principle of plunger suspension technology, the suspension force of the prop reaches 4 / 5 of the working resistance and the force of the column is 1 / 5. Therefore, the stability and safety of the column are greatly improved, and the bearing capacity and anti load capacity of the support height are improved.
2. No weld
There is no arc weld on the acrow prop column which is difficult to ensure by technology, which improves the strength and reliability of the column, avoids the hidden danger of roof fall caused by weld fracture, and ensures the safety of production personnel
3. Light weight
According to the different specifications of the acrow prop, the weight of DZ type is reduced by 15-20% compared with that of DZ type, and its weight is equivalent to that of aluminum alloy pillars, but the working resistance and working stroke are much higher than those of the parent alloy pillars, so it is more convenient to move, transport and use.
4. Long journey
The adjustable props working stroke of suspended hydraulic prop is large, so the application range is expanded. One specification can replace other Z-5 specifications of prop, thus reducing the specification, reducing the pillar reserve, improving the use efficiency and reducing the cost.
5. No internal leakage and more safety
There is no internal leakage in the adjustable props, and the leakage can be inspected visually by naked eyes. Once the leakage is found, it can be replaced in time. It avoids the false roof and tedious detection work caused by the leakage inside the adjustable props, and is safer to use.
