Geophysical Exploration Hydraulic Core Drilling Machine
SD-2000
SD-2000 full hydraulic crawler driving core drilling rig is mainly
used for diamond bit drilling with wire line. Because of the use of
foreign advanced technology,especially the mature rotation head
unit, clamp machine, winch and hydraulic systems,the driling rig is
widely used. It is not only applicable to the diamond and carbide
drilling of solid bed, but also to seismic geophysical
exploration,engineering geological investigation,micro-pile hole
drilling, and construction of small/medium wells.

Main Features
(1) Rotation head unit is a piston motor and mechanical gear style
which adopts the foreign technique. It has the wide range of
speed.Max torque is 4263N.m, so it can satisfy the different
project construction and drilling process.When the drill bit is
stuck at the end of the hole,it can solve the problem easily by
reverse hitting function.
(2) Max speed of the rig is 1120 rpm with torque 680N. m. It has a
high torque at high speed which is suitable for deep-hole driling.
(3) The feeding and lifting system uses the piston hydraulic
cylinder to drive the rotation head directly with a long travel and
high lifting force which is convenient to the deep-hole core
drilling work.
(4) The rotation head unit can move away from the drilling hole,
match the clamp and unscrew machine and finish the rope core
drilling operation easily, also it does not need the conventional
second platform work,especially replace the labor force to open and
close the rotation head unit when doing the slant-hole drilling
operation.
(5) Rig has the high lifting speed which saves lots of auxiliary
time. It is easy to wash the hole when doing the full driving
operation, enhancing the drilling efficiency.
(6) The rail of the main mast is l-beam butter-weld steel
construction to make sure the high rigidity between the rotation
head unit and the main mast. So it has a steady rotation even with
high speed which improves the drilling efficiency.
(7) The main winch is imported product with NQ2000M single rope
steady and reliable lifting ability.
(8) The wire line winch can get to max speed 205m/min at empty
drum, which saved the auxiliary time.
(9) The rig has the clamp and unscrew machine, easy to disassemble
the drilling rod and reduces the labor intensity.
(10) Rig feeding system adopts the back pressure-balancing
technology. The user can conveniently get the drilling pressure at
the bottom of the hold and increase the drill bit life.
(11) The hydraulic system is reliable, mud pump and mud mixing
machine are hydraulic controlled. The integrated operation makes it
easy to handle all kinds of incidents at the bottom of the hole.
(12) The movement of the crawler is linear controlled, safe and
reliable, can climb onto the flat truck by itself which eliminates
the cable car's cost.
(13) The rig is with high reliability, low cost of maintenance and
repairing.
