precise positioning indexes and locks
eliminate the need for troublesome
switches and sensors that are failure
prone due to dust and vibration.
From a maintenance and serviceability per-
spective, the HPR5128 is truly in a class of its own as
this rock drill has approximately half of the compo-
nents of competitive models, which means fewer
internal parts to wear, plus the unit is designed for
routine infield maintenance. Cat HPR6030 (30 kW)
and Cat HPR6832 (32 kW) rock drills are available
as an option.
During HPR5128 operation, self-maintenance
is assured due to Caterpillar’s new Auto Rock drill
lube system. This is a standard feature on the
MD5150, ensuring that internal components reach
full life expectancy at proper lube levels.

to supply up to five eight to ten-hour shifts, while
a timer board cycles the grease pump throughout
the day, eliminating maintenance time. High and
low pressure conditions are continually monitored
through the display screen.
In summary, the Cat MD5150 serves as a prime
example of Caterpillar’s ongoing research and devel-
opment investment in producing rotary and tracked
machines that help deliver lowest cost production.
As with any blasting programme, it all begins with
an optimally prepared grid, with Cat machines
ensuring precise diameters and clean hole depths to
ensure cost efficient fragmentation, and economical
downstream process recoveries.
