● 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.
