TDZQT400DR truck mounted drilling rig is a directly rotary drilling
rig. This truck chassis is adopt the 6×4 special chassis of brand
SINOTRUK, 11.00R20 steel off-road tire tread, with good off-road
This rig has very compact structure, the engine of chassis is
adopted WP7.210E40 diesel engine, the power is 155kw(strong power)
The drilling rig has independent diesel engine (DEUTZ-WP6G125E22),
the power is 92kw. Not only meet the drilling requirements, but
also reduce energy consumption, it is very affordable.
This rig is design principle is an advanced hydraulic cylinder for
drilling, stepless lift, it can be achieved automaic drilling. it
can automatically adjust the drilling speed for different
The drilling process can be achieved in pressruized 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 aviod crash the turntable and wellhead
board. When put down single drill pipe, operate the quick handle,
it can achieved release rope quickly like mechanical hoist.
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
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 BW850/2A 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.
