Atlas Copco Blasthole Drills - Matco

Atlas Copco Blasthole Drills
DM-M3

It all starts with the blasthole . . .
and the blasthole starts with the
DM-M3 power and performance.
A unique patented feed system:
• Longer head travel with smaller cylinder
rod.
• Heavy-duty cables that provide 1:4
weight reduction over chain.
• Interchangable cable pieces.
• Less tower weight with better
distribution for tramming.
• Cable that detects wear earlier and is less
expensive than chain.
An unparalleled rotation system:
• Largest continuous torque/RPM envelope
available.
• Instant compensation to changes in
ground conditions without special gear
set removal or addition.
• 2-stage reduction with large spur gears
maintains inertia and is more durable
than external planetary gears.
• High pressure, low flow, pressure
compensated closed loop hydraulic
system is more efficient and longer lived.
• Power head weight exceeds 5,000 lbs
(2,313 kg) to add to bit loading.
A strong and rigid drill tower:
• Four main member, open front ASTM
A500 Grade B rectangular steel tubing;
cold sawed and welded.
• Double cut lacing used to contain
bending moments within the tower
structure.
• Two (2) hydraulic 8" bore (20.3cm) tower
raising cylinders.
• Tower can be raised and lowered in
seconds with a full complement of drill
pipe in the carousel and under the rotary
head.
• Remote pinning from the cab.
• Patented angle drill system available as
an option - keeps pivot point at drill deck
and drill pipe always within the dust
curtain even at 30 maximum.

Versatility and adaptability:
• The DM-M3 is available with many options and
choices of features to permit it to adapt to any
mining situation anywhere in the world.
• New processes are in place to expand the
capabilities of the DM-M3 even more.
Product support and parts:
• Atlas Copco worldwide network will support the
DM-M3 wherever there is drilling to be done.
• Genuine Atlas Copco parts will keep your
DM-M3 running at peak efficiency.
A reliable and efficient power pack group:
• Air compressor, prime mover and hydraulic
pumps in-line, driven by double-ended shaft
with flexible coupling to better maintain
alignment.
• Floating subframe minimizes transmission of
shock loads to power pack.
• Separate, 3-stage inlet dry-type air filters for
compressor and engine.
• Standard split cooling to 125 F (52 C) with
separate cooler for hydraulic oil and compressor
oil.
• Ambient air used through the coolers rather
than heated air over the engine.
• Closed loop hydraulic system for greater
efficiency.
• Three (3) hydraulic pumps as opposed to 5-7, to
reduce parasitic load.
• Diverter value used rather than clumsy
mechanical disconnects, prevents accidential
tramming while in drill mode.
• Excellent access to the hydraulic pumps for
reduced service time.
• Two (2) sets of 3 micron filters minimize
hydraulic contamination.
• Compressed air is not used to supercharge
pumps in order to reduce fire hazard.
• Ingersoll-Rand asymmetrical, oil-flooded rotary
screw air compressor for single-source
warranty and service responsibilty.
• Compressor is rated at 110 psig (758 kPa) for
better bit cleaning, cooling and lubrication.
• A gear pump provides positive lubrication to
the compressor bearings at all times.
• A "zero-load" system to unload compressor
when not needed to extend compressor life,
reduce fuel use and promote easier cold
weather starting.
• Coolers are located on the sides of the drill
deck, not under the tower rest where drill dust
can be ingested when the tower is lowered.

A sturdy and stable drill platform:
• Mainframe designed and weld fabricated
of ASTM A-441-50 I-beam; 24 x 146.
• Radius gussets used for reinforcement
at major stress points for reduced
deflection and better stress distribution.
• Three hydraulic leveling jacks for
maximum "tripod stability".
• An "Excavator-type" undercarriage is
used for better traction and slewing
ability.
• Triple-bar grouser pads are replaceable
for reduced maintenance and down time.
• Oscillation yoke mounting with 5 each
direction or total 10 up and down to
minimize stress on frame and
components.
• Two (2) hydraulic motor drive powered
by hydro static closed loop system,
through planetary gear speed reducers
for maximum efficiency.
• Spring applied, hydraulic release brake
system for safety.
• Drive system can be disengaged for
towing.
A comfortable and efficient operator
environment:
• Sealed, pressurized and heated cab with
large tinted windows; sound abatement;
ample work area and headroom.
• Air conditioner available as an option.
• Controls are electric over hydraulic for
ease of operation, and concise and rapid
response.
• Excellent visibility of the drill deck for
safe and efficient operation.
• Standard 6 light package for safe nigh
time operation with option for 12.
• Machine access lighting of ladder and
cab when engine not operating, for
added safety.
Quality assurance:
• ISO 9001/Q9001 registry.
• In-place Quality Assurance Programs
and Objectives at the manufacturing
plant headed by full-time staff.
• Employee involvement quality program
at all levels.
• Preferred supplier program to assure the
high level of proficiency and performance
levels that Atlas Copco demands.
