(1)No noise, no vibration, and high safety. Without slurry, it is environmentally-friendly, avoiding the possibility of slurry’s entering the concrete, and enhancing the bond stress of concrete to the steel bar.
(2)360 degree rotation increases working efficiency.
(3)Two control types available: hydraulic control and remote control.
(4)Fast drilling speed up to 14m/h for the general soil layer.
(5)Large drilling depth up to over 100m according to soil layer condition.
(6)High borehole verticality up to 1/500, and good walling quality.
(7)Standard boring diameter of small filling factor can save a lot of concrete consumption.
(8)Large torque and pushing force ensures the application in hard stratum with hardness up to 60MPa.
(9)Can be powered by a separate hydraulic power pack.
