DFT-400 Trailer mounted deep water well drill rigs
1. DFT-400 water well drill rigs are a portable trailer mounted water well drilling rig. It can drag on tractor for moving, convenient and quick, with high working performance. It is equipped with 108x108x7500mm square main drill rod, and Φ89x6000mm normal drill rod.
2. When drilling, it has independent diesel engine as power, making winch and turntable working by mechanical transmission.
3. Equipped with four hydraulic legs. The four legs can work at same time or separately working, to keep good balance. Meanwhile, the rear legs can stretch out horizontally, improving the stable working. Drill tower is raised by hydraulic cylinder, stable and easy to operate, apply to different working conditions.
4. Main parts include winch, turntable, gearbox, drill tower, chassis, are all manufactured in our factory, with stable performance.
5. It is widely used in high-rise buildings, bridges, geological mine, port, dam foundation, well construction, complex ground source heat pump, etc.
6. Easy operation, strong capacity, easy maintenance, low investment.
