Truck mounted large model DFC-400B 400m deep bore hole drill rigs   Brief Details Brief Details of DFC-400B deep bore hole drill rigs: 1. Model No.: DFC-400B 2. Max. Drilling Depth: 400m 3. Borehole Diameter: 500mm 4. Warranty: One year guarentee excluding wearing parts 5. Certifications: BV,SGS Certificate 6. Applications: water well geological exploration, irrigation well etc. Product Description Applications of DFC-400B deep bore hole drill rigs:

Our vehicle mounted drilling rig has found applications in water conservation projects, the drilling of industrial deep well, conventional water well and geothermal well, etc.. It is applicable for drilling into clay, sand, bed rock, basalt strata, and more.  
  Features of DFC-400B deep bore hole drill rigs:
1.DFC-400B truck mounted drilling rig is designed by our engineers; it is adopt truck mounted and is a rotary drilling rig.   2.The truck chassis is adopt the 8×4 special chassis of brand CHANG’AN TRUCK, the main transmit, transmission power, gearbox, sets of windlass, mud pump, sewage pump,mast are setup on the chassis.   3.This rig is a rotary drilling rig with directional circulation, which is equipped with BW850/2A mud pump. It adopts the slurry as the washing fluid, it can drill on clay, sand and rock if it is equipped with a good drilling bit.   4.The power of drilling rig comes from the truck engine; the rig sets up distribute implement and hydraulic system.   5.We can set up the spare electric engine and clutch implement according to client's requirement, so that the rig can work with diesel engine or electric engine.   6.We can set up a generator (15kw) , so that it is convenient to illuminate or work at night.   7.The adding pressure implement is hydraulic, so it has a high efficiency when the rig drill on mud rock and weathering formation through using the adding pressure implement.   8.The master driving of rig is mechanical, the four jacks and mast are hydraulic operated. Distribute box, sewage pump, master driving clutch system are air operated.   9.The appearance of rig is pretty. It has a high efficiency because of having a larger torque of the turntable, it is mainly used for water well, construction, national defense building foundation, geological exploration, geothermic well and other foundation working. It is popular with domestic and foreign clients.     Parameters of DFC-400B deep bore hole drill rigs:
