Our company produces“QEU”Performance characteristics of series direct connected rope drilling tools

1. Produced according to the DCDMA standard established by the internationally influential American Diamond Core Drilling Machine Manufacturers Association, this series of products has been continuously improved and developed by NLC Corporation in Japan, and is interchangeable with foreign standards.

2. The QEU tunnel rope core drilling tool adopts the pump pressure conveying drilling tool method for drilling, which solves the problem that ordinary rope drilling tools cannot be used for horizontal construction.

3. Reduce the wear and power consumption of the drilling rig lifting operation system. Significantly improve the efficiency of diamond core drilling.

4. The card part adopts a rocker arm mechanism, and the relative expansion spring fully ensures the opening and closing size of the card, effectively avoiding the occurrence of accidents,

5. Wear prone components such as spring calipers, suspension rings, and fishing heads have been nitrided to ensure strength and service life

6. The single action mechanism adopts imported bearings from abroad, which not only reduces the occurrence of underground accidents in harsh cement slurry environments, but also increases its service life,

7. The vast majority of parts in NQIU and BQEU are interchangeable, greatly reducing the procurement cost of vulnerable parts for customers

8. The QEU series of salvagers are basically universal, reducing customers' procurement costs
