The MD5075C has the largest
pattern coverage in its class, a fast
rod changer for improved cycle
times, fast tram times from hole to
hole and a comfortable cab with an
improved operator interface.

and electronics-free rod changer (free of
sensitive sensors that can cause excessive
downtime), and a Cat-engineered power
train with matched horsepower.
Major components are built to last
the life of the machine, and Caterpillar is
the only manufacturer offering rock drills
designed to be serviced on-site.
“One hundred percent of all rock
drill services can be completed without
removing the drill from the feed,”explains
Barloworld Equipment Cat drill product
manager, Ramon Glaus, adding that the
drills are equipped with Cat ET (Electronic
Technician) diagnostic software to
quickly troubleshoot the entire machine.
Barloworld Equipment is the Cat dealer
for Southern Africa.
“With up to three times the lifespan
and less than one half the parts cost of
competitive rock drills, Cat units deliver
with maximum uptime at an overall low
total cost of ownership.”
At the business end, the new Cat
MD5075C is capable of drilling 76,2 mm
to 114,3 mm diameter holes to a depth of
31,2 m. The standard rock drill for this unit
is the 23 kW HPR5123, which accepts 45
or 51 mm drill steel. Also available is the
HPR4519 rock drill, which uses a 45 mm
drill rod specification. The compressor,
which features widely variable air control,
produces 9,9 m
3
/min @ 10,2 bar.
“Thanks to industry-leading pattern
coverage, the MD5075C is able to drill up
to three to four holes per set-up before
having to tram and reposition,” Glaus
expands.
Power delivery is via a Cat C9 engine
rated at 224 kW with machine mobility
provided by a reliable Cat 315E undercar-
riage that can be rebuilt. Track assemblies,
fitted with 380 mm triple grousers, are
hydraulic motor driven, ensuring fast and
smooth tram speeds over rough terrain.
The standard rock drill for the Cat MD5075C is
the 23 kW HPR5123, which accepts 45 or
51 mm drill steel.
Largest in class, the Cat MD5075C has a 3,81 m boom, plus a 1,5 m boom extension. This
keeps operators a total of 5 334 m away from a ledge or highwall. The boom is constructed
of thick square tubing with steel plate reinforcements in key areas to add strength.
