Main features：

◎BZCY400XHW truck mounted drilling rig is a directly rotary drilling rig. This truck chassis is adopt the 6×4 special chassis of brand SINOTRUK HOWO, 371HP, 11.00R20 steel off-road tire tread, with good off-road performance.

◎This rig has very compact structure, the truck moving and the drilling use the same engine (PTO).

◎This rig design principle is an advanced hydraulic cylinder for drilling, stepless lift, it can be achieved automatic drilling. it can automatically adjust the drilling speed for different geological conditions.

◎The drilling process can be achieved in pressurized drilling technology, adjust different pressure for different geological conditions, and can be viewed drilling pressure by pressure gauge. At the same time, it can adjust the drilling speed.

◎The drilling rig can achieved fast drilling by manually, especially for soil. It can achieved different speed for different soil.

◎It has a large lifting force hydraulic main hoist, stepless lift, and to achieve release rope quickly. When upgrading heavy, the lifting speed need slow to avoid crash the turntable and wellhead board.

◎It has a hydraulic tool hoist, the tool hoist has large lifting force and quick lifting speed, it is both easy to loading drill tools, drill pipe and drill accessories transport, and can slide up and down with anchors, its very convenient to load and unload the drill pipe.

◎It has a hydraulic cylinder control double card board forward and backward, it makes the insurance card board closed, to achieve stuck or release the pipe joints.

◎It use integrated design of pneumatic, to achieve the BW850/2 mud pump clutch using pneumatic remote control, it has high degree of automation and easy-saving operation.

◎It is installed 4 hydraulic legs and 2 mechanical legs, every hydraulic leg rod with locknut。 After leveling the rig, it can lock the cylinder use locknut. So, even if the cylinder leaks, the chassis is not instability.

◎The turntable use stir bars, internal turntable use spiral arc gear to transmission, it has large torque, it about 2 times of similar products at domestic and foreign.

◎It is installed a generator (30kw) , so that it is convenient to illuminate or work at night.

◎The hydraulic system use open system, the chassis and drilling rig are separately manipulated, it can avoid misuse. Winter oil heater and summer oil radiator are installed, to adapt to different seasons hydraulic oil for heating and cooling.

◎This drilling rig equipped with an auxiliary unloading cylinder, it can be used to promote the turntable ratchet, to achieve auxiliary unloading the drill pipe.

◎ According to client’s requirement, the rig can carry out down-the-hole hammer drilling with Atlas, China Kaishan,Zhigao;  can carry out other drilling methord with other special drilling tools.
