Main features：
◎ BZC-350ZYII truck mounted drilling rig is designed by our engineers; it adopts truck mounted and is a rotary drilling rig.
◎ 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.
◎ The power of drilling rig comes from the truck engine, the rig setups distribute implement and hydraulic system.
◎ We can upset the spare electric engine and clutch implement according to client's requirement, so that the rig can work with diesel engine or electric engine.
◎ The adding pressure device is hydraulic, so it has a high efficiency when the rig drill on mud rock and weathering formation through using the adding pressure implement.
◎ 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.
