Purpose:
Model
SG3 Engineering Drill Rig applies to the drilling
of engineering basic hole for high building, bridge,
harbor and dam, also for the large diameter water
well and other engineering holes.
Mechanism feature:
1、This kind of rig is mechanical
drive, controlled by machinery and hydraulic. Its
mechanism is compact, easy to operate, safe and
convenient to load,
2、The rotary table with six gears
speed applies to the drilling for the holes of
all kinds of stratum and diameters, and drilling
efficiency is high.
3、This kind of rig is equipped
hydraulic device to open borehole so that it is convenient
to lift and drop the large diameter drill tools(max
φ 2m).
4、The main and auxiliary hoists with
the mechanism of planetary gear train is easy to
operate and lift capacity is strong.
5、The mast is
installed a guide way to the benefit of verticality
of borehole and is also equipped the hang device
of tap and driving petroleum drill rod to fulfill
the operation without personnel on the mast in order
to reduce labor intensity and shorten the time for
lifting and dropping the drill tools |
