Compared with traditional wooden pillars or other support methods, it saves a lot of manpower and working hours, effectively improves the excavation efficiency, and meets our needs for rapid construction.

Customer 4

The hydraulic pillar sealing system of Changmiaoxin is finely crafted and made of excellent materials, which can avoid the problems of hydraulic oil leakage and pressure loss. We did not find obvious leakage during long-term high-intensity operations, with a long maintenance cycle and few overhauls, which significantly reduced equipment maintenance costs and downtime losses.

Customer 5

The products purchased from Changmiaoxin can adapt to the harsh underground environment for a long time. The performance remains stable after repeated use. Compared with other support materials, it has a higher cost-effectiveness and obvious long-term return on investment. It is an important choice for updating and upgrading our mine support equipment.
