1. BZC-350DF truck mounted drilling rig is designed by our engineers;
2.it is adopt truck mounted and is a rotary drilling rig.
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 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.
5.The rig 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.
