D-90
DRILL SPECIFICATIONS |
| Performance
ratings are based on engineering specifications,
calculations and accepted industry standards. Capacities may
vary according to drilling conditions. Diedrich Drill
reserves the right to amend these specifications at any
time, without notice |
| GENERAL |
Heavy duty drill rig for soil and rock
exploration using augers, rotary tools or core drilling tools.
Rated to
depths of 150 ft.(46 m) to 300 ft. (92 m) with hollow stem or continuous flight augers up
to 19 inch (483 mm) hole size.
Rated to 1500 linear feet (458m) of core drilling using NW series tools. |
| POWER UNIT |
The drill is powered by a
4-cylinder turbo-charged diesel engine.* 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 rotary box on the standard D-90 consists of
a #100 triple strand chain drive which is totally enclosed and running in oil. The quill
and spindle are supported on tapered roller bearings. The lower bearings run submerged in
oil and the upper bearings are externally greased. |

| HYDRAULIC SYSTEM |
Oil is supplied by a heavy-duty 2-section gear
type pump rated at 20GPM(76min) 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 valves 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.
4-1/4"(108mm) I.D. HSA box is standard, other sizes available. |
