Steering is provided by the drill’s two joystick CANbus controls and
foot pedals for precise positioning.
A high resolution in-cab display enables touch screen naviga-
tion for Cat Connect technologies like Drill Assist, which monitors
main hydraulic systems and automatically adjusts to pre-pro-
grammed parameters.
Drill Assist incorporates anti-jam, anti-plunge and anti-plug,
resulting in higher productivity and increased life of the drill string.
Other touch screen readouts include a drill depth indicator, which
ensures all holes in a pattern are drilled to the planned depth. This
helps promote a better floor, and reduces the need for secondary
blasting.
Optimum drilling
Like the MD5075C, the latest generation Cat MD5150C (which
replaces the Cat MD5125) comes with high productivity fea-
tures refined via extensive in-field production studies. The latest
MD5150C model upgrade was announced to the market just over
a year ago.
Intended for higher production requirements, hole diameters
on the Cat MD5150C range from 101,6 mm to 152,4 mm with a
multi-pass hole depth to 31 m. Power is provided by a Cat C11
engine rated at 287 kW.
“Choosing between the two drills will clearly depend on the
site conditions and downstream targets,” adds Glaus. “Either way,
both models lead in their class to ensure that high drill uptime
keeps production flowing.”
