Hydraulic Core Drill Rig , Top Drive Drilling Rig 5'' Rod 127mm
TDR -80 is mainly used for coal bed methane exploration, water well
drilling, rescue well drilling, shallow oil and gas, mine
exploration drilling etc.
The TDR-80 multifunction top drive rig enables each user to drill
with following methods, with borehole diameters of 4″(108 mm) to
47″(1 200mm) and drilling depths up1500m
● Rotary-drilling with direct circulation
● Rotary-drill with reverse circulation
● Auger drilling
● Percussion core drilling(ram coring)
● Wire line core drilling
● Down-The-Hole hammer DC and RC drilling
Drilling Depth Guidelines
Use 5″rod 127mm 1800 – 1 500 m
Use 4-1/2 ″rod 2000– 2400 m
Use 4″rod 2800 – 3200 m
The figures in these tables have been calculated, based on field
experiences, based on a vertical, straight, and clean down hole.
Actual drilling capacity will depend on in-hole tools, conditions,
drilling techniques and equipment used.
The TDR-80 is mounted on the undercarriage of excavator with a
total weight of 58 ton. The engine power 552 Kw.
Constructed of high tensile steel and hydraulically elevated,
lowered and setting by four (4) double acting hydraulic cylinders.
The mast is equipped with 4 guide rails for the carrier of the
drill head and a suspension for the feed device. The rig also is
equipped slipper system, in order to the mast slip, and the stroke
is 3.65m, lead to the mast can support on the ground. The rig can
set up the blowout preventer and other system.
Mud Line System
All mud lines on the TDR-80 Drilling Rig have 3" (76.2mm) diameter,
in order to reduce friction losses to a minimum.
Top Drive head
Top drive head suits for tricone bit, DTH hammer, PDC Dill bit and
diamond bit which meets special demand of rotate speed and torque
during work. The 4-shift Gearbox using spur gear drive, oil bath
lubrication. Hydraulic Motor and gearbox could provide for much
high speed and torque to be adjusted.
The angle of rotate unit could be adjusted as needed, ranges from
Generator and batter driven by diesel engine altogether provide 24V
direct current. All cables are protected by seal line. Furthermore,
all circuits are equipped with short-circuited.
Additional Rig Components
TDR-80 Rig can be modified. All kinds of aggregates, required for
different drilling methods, can be installed on the rig at customer
request, or supplied as stand-by aggregates.
