Drill rod and drill bit:
Drilling machine uses screw drill rod and flange coupling. There is no valve at the bottom of the drill rod, so that it can stop silt leaking into the center tube. Moreover, the tube can open automatically when concrete or slurry is injected in by force.
Power Head:
The power head consists of two wind cold motors, a speed reducer, an elbow, a pulling yoke, and a sliding block. When working, the two motors revolve the high speed shaft of the speed reducer through their couplings to pass power to the low speed shaft, then the low speed shaft revolve the drill pipe though its flange. The low speed shaft, being a hollow shaft, connects the syphon through a sealing device.
Moving device:
Electromotion caterpillar travel type and step moving type are adopted for walk mechanism, which bring a good result of convenient movement, high efficiency, low troubleshooting and low maintenance cost. The crawler of electromotor caterpillar travel type touching the ground is 2.8 to 5M, and every step stroke is 1.2M to 2M, bring up great convenience to construction.
* Using support cylinder during construction process enable drilling machine to be more stable and reliable , avoid side tumbling accident . Whats more, equiped with different cylinder support le realize the 360°full revolution, step type and electromotor type long screw drilling machine are convenient to operate.
*Advanced electric control system is reasonable and reliable. Electronic components come from world-class brands, features stable and reliable. The use of wire control system reduces the amount of commanders. Operators can find the pile position correctly.
*Rotating mechanism can realize the 360°full revolution. The speed reducer with large frame makes sure of the less damage.
