1. Machine adopts pneumatic shift Fastgear 8JS118 auto transmission
and clutch, compact structure, smooth operation, stable
performance, good wildcard.
2. Using auto-control flexible-shaft shift agency, we achieve the long-distance transmission shift. The
pneumatic shift is light and agile, and has the advantage of hommization.
3. Reasonable speed range and many speed radixes (8 forward speed,
1 reverse speed), with low-speed it has big torque (Max. up to
8000N.m).
4.Using concentrated forced lubrication system, as long as the rig
runs, the separate lubrication oil pump starts working and sends
lubrication oil to each node that requires lubrication. When the
oil lubricates drive mechanism, it will also take away the heat
inside, (lubrication system with separate condenser), to prevent
the components from heat caused by high-speed high-load state.
5.The rig adopts involute splined vertical shaft instead of the
traditional hexagonal vertical shaft, exponentially increasing
gyrator transmission efficiency and carrying capacity . And new
spindle shaft has big hole diameter (96 mm), with twin cylinder
hydraulic feed the trip is much longer (up to 1000mm), especially
suitable for large diameter drill pipe wireline coring, help to
improve drilling efficiency and reduce the hole accident.
6. Light weight and can be disassembled to many parts, net weight
6500Kg.
7.The chuck is hydraulic-release normally closed hydraulic chuck,
new structure, good compensatory. Carbide inset&welded slip
structure, has large clamping force, long life, reliable operation.
8.With water brake, in deep hole drilling, it’s safer and more
smooth to put down the drill pipe.
9. Hydraulic oil is supplied by gear oil pump, less power
consumption, and the hydraulic system oil temperature is low and
stable work. The system is equipped with a hand pump. When power
machine can not work, workers can still use hand pump to lift tools
from the bottom of the hole, in order to avoid burying accidents
10.Advanced and compact structure, reasonable layout, all
components are revealed outside, do not overlap, ease of
maintenance, maintenance and repair.
11. The rig has a low center of gravity and long backward stroke
(up to 530mm). Easy to be fixed on tower base, the rig has good
stability in high-speed drilling.
12.With shockproof meter, it’s easy to observe hole situation.
Control-handles are in reasonable layout, operation is flexible and
reliable.
