1. Spin head directly driven by low-speed and high-torque hydraulic motor is adopted. With more simple butreliable structure. The seal of the spin head effectively prevents high-pressure air and water from leaking intorerrarmotor cavity. Spin head can be easily maintained and has a longer service life. (TongGuan's patented technology).
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.
B. 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.
C. 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.
D. 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 circles without moving. (Tongguan’s patented technology)
E. 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.
