1. There are more speed grade (8 grades), reasonable speed range
and high torque while low speed. Max. Torque is up to 3200 N m
(2358 lbf ft). The drill is adapted on core drilling with
tungalloy-carbid-tipped and diamond oil as well as engineering
geology exploration, hydrology well drilling and basic pile
engineering.2. With large spindle I. D. 93mm(3.66 inch), the drill
is fed with double hydraulic cylinders with much longer stroke up
to 600mm(23.62 inch). With strong technological adaptability, the
rig can be adapted on many field, especially on large diameter
drill rod drilling, (upper part coring) extracting core with wire
line. Thus it is more effective in improving drilling efficiency
with less faulty in hole.3. With powerful drilling capacity, the
rated drilling depth comes up to 1, 000m(39.37 inch) with 71mm(2.80
inch) wire-line coring drill rod.4. Light in weight, and in fine
dismountability, the rig can be dismantled into ten parts easily,
the biggest apparatus is in 300 kg (661.5 lb). The whole drill is
in 2150kg(4741 lb), it can be moved easily especially in mountain
area.5. Clamped with belleville spring and loosened with hydraulic
cylinder, the hydraulic chuck is adopted with three-jaws self
centering. It is in strong and steady clamping force.6. Equipped
with a water brake for steady and smooth deep hole drilling.7.
Supplying oil with a simplex gear pump, it is easy for installation
and operation; Lower in energy consumption and in low oil
temperature of hydraulic system; The rig is for sure in steady
drilling. The hand-operated oil pump can be put in use to hoist the
drilling tools in hole upon the power engine failing to operate.8.
With compact structure and reasonable layout, with all components
exposed, and with non overlapped ones, it is convenient for
maintenance.9. With low center of gravity and long travelling
distance up to 460mm(18.1 inch), the rig is reliable and stable in
high speed drilling.10. It is easy to get to know the conditions in
hole with an antivibration meter. Less in operating handles, the
rig can be operated credibly and flexibly.Drill Rod VarietiesDrill
