Main technical features of Wuxin three-arm rock drilling jumbo

1. Accuracy: Fully controlled with the computer, the drilling system is capable of automatic positioning and drilling, accurately controlling the propulsion beam's angle and hole depth to minimize the over-excavation.

2. Safety: Only 3 persons are required to operate one drilling jumbo, so the workers can stay far away from the tunnel face, which makes the construction safer.

3. High-efficiency: The construction progress can be sped up as it features automatic drilling, automatic sticking prevention and high-speed single hole drilling.

4. Stability: The rock drills, main hydraulic components and chassis transmission systems are all imported well-known brands.

5. Operator-friendliness: Equipped with the fully enclosed cab, it is operator-friendly as the personal injury due to noise and dust can be minimized.
