| |
| GENERAL |
Heavy duty drill rig for soil and rock
exploration using augers, rotary tools or core drilling tools.
Rated
to depths of 200 ft.(61 m) to 350 ft. (107 m) with hollow stem or continuous flight augers
up to 19 inch (483 mm) hole size.
Rated to 2000 linear feet (610m) of core drilling using NW series tools. |
| POWER UNIT |
The drill is powered by a
4-cylinder turbo-charged diesel.* Electric starting and engine instruments are standard
* Other engine options are available |
| FRAME & BASE |
The drill frame is a weldment,
constructed of heavy wall rectangular steel tubing, with sufficient strength and rigidity
for heavy duty use. |
| CLUTCH & TRANSMISSION |
Clutch - 13 inch (330mm) automotive type.
Transmission
- Heavy duty helical gear transmission with 5 forward and 1 reverse speed.
Optional Cathead is driven by a power-take-off providing 1 speed
forward and 1 reverse. |
| RIGHT ANGLE DRIVE |
The right angle drive is a heavy-duty
spiral bevel gearbox, totally enclosed, and running in oil |
| ROTARY BOX |
The drill head utilizes a 2 speed all
gear drive with 8620 heat treated gears. Tapered roller bearings, running in SAE 90W gear
oil, are used. A chuck is available(optional) for all standard size rods and casing. |

| HYDRAULIC SYSTEM |
Oil is supplied by a heavy-duty 2-section
gear type pump rated at 20 GPM(76l.min) and 28 GPM(106l/min). Maximum operating pressure
is 2300 PSI(15513k Pa). The pump is driven by a drive shaft connected to the front of the
engine or from the engine auxiliary drive.
Hydraulic
valves are stock sectional body directional control vavles with an integral non-adjustable
relief valve. An optional regenerative spool
can be provided for the main feed valve providing a high
speed spindle lift as well as normal operation. |
| AUGER ADAPTER |
A heavy universal joint, which mounts to
the spindle with a single nut, is provided for ease in hook-up and adjusting for
misalignment. All components are sized to withstand severe combinations of torque and
axial load. 6-1.4"(159mm) I.D. hex box is standard, other sizes available. |
