ST260 Crawler Pneumatic Drilling Machine Impact Type Large Bore Deep Well Drilling Machine
Application scope of ST-260 crawler pneumatic well drilling rig
Pneumatic drilling rig is a kind of fast deep well drilling
equipment which uses high pressure air as power source. It is
suitable for industrial and civilian drilling, geothermal drilling
and other purposes, especially for water intake engineering in
mountainous rock formation.

Technical parameters of 260 crawler pneumatic well drilling rig
1. Large diameter, deep drilling, fast footage, flexible and
efficient. Equipped with large torque hydraulic motor and large
diameter hydraulic cylinder propulsion, the design of * * pump
group is convenient for maintenance.
2. The drilling rig adopts crawler chassis of excavator, with
strong off-road ability, independent modular design and excellent
mobility.
3. Combined positioner can be adjusted and replaced according to
different types of drill pipe and impactor to ensure accurate
positioning and centering.
4. The chassis is equipped with four high-strength hydraulic high
outriggers with strong bearing capacity. The supporting height of
the outriggers can reach 1.5m. The loading and unloading truck can
reduce the hoisting cost and can be used as a leveling and
stabilizing drilling rig.
5. The hoisting mechanism is convenient for the hoisting of
drilling tools, reduces the labor intensity of the operator, and
saves time and labor
Advantages of well drilling truck:
1. Full hydraulic control, easy to operate, easy to move, good
mobility, time-saving and labor-saving.
2. The rotary device of drilling rig is driven by hydraulic motor,
with large output torque and lower rotary center than similar
products, which greatly improves the drilling stability of drilling
rig.
3. The new variable angle mechanism makes the hole more convenient
and the adjustment range larger, which can reduce the requirements
of the working face.
4. It can be used with the pipe following drilling tools, drilling,
hole quality is good.
5. JK series is a full hydraulic rotary well drilling rig with
modular structure, which can be equipped with crawler or wheel
traction.
6. Lifting power; The design of composite boom has the advantages
of small volume, long stroke, double oil cylinder lifting and large
lifting tonnage;
7. The lifting boom of each drilling rig is equipped with a limiter
to protect the oil cylinder and ensure the work;
8. Each hydraulic oil pipe is wrapped with a protective jacket to
prolong the service life of the oil pipe.
