● Safe Reliability:

1. The slewing head is directly driven by the low-speed and high-torque hydraulic motor, and it’s structure is simple and reliable. The sealing device of slewing head effectively prevents high-pressure air and water from leaking into slewing motor; the turret has long life and simple maintenance. (TongGuan's patentedtechnology).

2. The air and water system is integrally connected by motor and washing machine, with reliable performance and long service life.

3. Refuelling system by electronic impulse makes impactor more efficiently lubricated and have a longerservice life

4. This product has passed inspection which was held by State Production Safety Committee ChangSha Mining Mechanical and Electrical Equipment Inspection Center and obtained Mining Equipment Safety Mark"certificate which was issued by State Mining Products Safety Approval and Certification Center.

● Drive Mode:

1. The electricity power, low cost, low energy consumption, low noise.

2. The four-wheel adopts Italian Bonfigli motor independent drive, makes the drill rig have strong walking ability and be able to spin in circleswithout moving. (TongGuan's patented technology)

● Drill Performance:

1. The guide rail adopts a V-shaped structure, makes the drilling accuracy improved and the deviation slope less than 1%.

2. With faster dilling speed that one minute can drill 0.2m-0.3m.

● Drill Adaptation:

1. The rotary drill boom adopts gear rack, with large torque and reliable positioning. Provides all-round rock drilling.

2. Stable and reliable support mechanism to ensure drilling accuracy.

3. Stope height no lower than 3.2m, no higher than 3.6m, roadway width no narrow than 2.6m.

● Control Performance:

1. Hydraulic rod unloading system alleviates labor intensityand and saves auxiliary operation time.

2. Drilling and positioning can be controlled on movable platform which can realize long-distance and multi-directional operation.
