Product Description

The main features of the double telescopic hydraulic strut are its high support force and stability, and it can be adjusted quickly and precisely as needed. Both the upper and lower parts of the support column are equipped with high-strength threaded connectors, which enable them to be easily connected and disassembled. In addition, the double telescopic hydraulic prop is also equipped with functions such as automatic compensation and sensor monitoring to ensure that the supporting force is always in the best state under the condition of changing geological conditions.

Double telescopic hydraulic props are widely used in underground projects such as coal mines, metal mines, tunnel construction and subways. Compared with traditional wooden or steel props, double telescopic hydraulic props have higher bearing capacity and better adaptability, and can better cope with changes in geological conditions and vibrations. In addition, it also improves productivity and safety thanks to its automation and remote monitoring capabilities.

Bolt support is being applied to fix rock strata which are slacking off due to a decreasing pressure of strata in the area of mining excavations at the stable rock mass. This is being done by inserting a bolt into a drilling hole that is then either wedged mechanically or along the whole length or sections cemented or pasted together with the adjoining rock. The anchor bolt transmits the tension to the screwed roof-bolt head.
