trailer chassis water drilling rig
SPJT300 Water Well Drilling Rig is installed on a trailer. This
drilling rig can work through rotary mud circulation or DTH
drilling technique. SPjT300 trailer chassis water well drilling rig
is suitable for clay, sand, graveland pebble, and rock stratum. We
add special device to add & reduce pressure during drilling which
can enhance efficiency a lot. High hydraulic leg and hydraulic
tower are chosen to save labor and keep safety during working.
◎ when drilling, the drilling rig uses an independent diesel engine
as power, and uses mechanical transmission to make the mechanical
winch and rotary table work at the same time;
◎ the drilling rig is equipped with four hydraulic support legs,
which can move at the same time as well as independently,
facilitating quick leveling of the drilling rig. Moreover, the two
rear legs can extend horizontally, thus improving the stability of
the whole drilling rig. Using hydraulic cylinders to lift the tower
is convenient, reliable and simple to use, which can meet the
construction requirements of different working conditions to the
greatest extent.
◎ the main parts of the drilling rig, such as winch, turntable,
gearbox, tower and chassis, are produced by our factory
independently, with stable and reliable performance.
◎ the drilling rig is suitable for drilling high-rise buildings,
bridges, geological mines, ports, dam foundations, water well
construction, complicated ground source heat pump, etc.
◎ the drilling rig is simple to operate, has strong usability,
convenient maintenance, less investment and quick effect, and is
the best product for users.
