D-50 DRILL SPECIFICATIONS
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.
||All purpose drill
rig for soil and rock explorations using augers, rotary tools, or core drilling tools.
Rated from 125 ft.(38m) to 250 ft.(76m) depth with hollow
stem or continuous flight augers up to 14"(356mm) hole size.
Rated to 1000 linear feet(305m) of core drilling
using N series tools.
|FRAME AND BASE
||The drill frame is
a weldment, constructed of heavy wall rectangular steel tubing, with sufficient strength
and rigidity for heavy duty use.
||The basic D-50
Magnum unit is powered by a 4-cylinder diesel or
a 4 cylinder turbo charged diesel engine.* Electric starting and engine instruments are standard.
*Other engine options are available
||Clutch - 13
inch(330mm) automotive type. (60HP gas engine uses 11 inch(279mm) clutch)
Transmission - Heavy duty helical gear transmission with
4-forward and 1-reverse gears.
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 gearbox, totally enclosed, and running in oil
||The rotary box
consists of a 80# triple-stranded roller chain drive, totally enclosed, and running in
oil. The quill and spindle are supported on tapered roller bearings. The lower bearings
run submerged in oil. The upper bearings are externally greased.

||On the D-50 unit,
oil is supplied by a heavy-duty gear type two-section pump rated at 19 GPM(72 l/min) and
24 GPM(91 l/min) at 2400 RPM. Maximum operating pressure is 2300 PSI(15,513 k Pa). The
pump is gear driven from the engine accessory drive or from the front crank shaft.
The hydraulic valves are stock sectional body directional
control valves with an intregal non-adjustable relief valve. All controls are conveniently
located on a single console for ease of operation.An optional regenerative spool
can be provided for the main feed valve providing a high
speed spindle lift as well as normal operation.
||A heavy duty
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 torque and
axial loads encountered under most drilling conditions. 1-5/8"(41.3 mm) female hex is
standard, other sizes available.
