Trailer Mounted Drilling Rig
Light rig. Serious thrust.
The Power Mite is a fully hydraulic diamond drilling system built for inaccessible sites — every component runs off hydraulics, so there are no mechanical drives to fight, and the screw feed still delivers 2,500 kg of thrust.
2,500 kg
Screw-feed thrust
About twice the pull/thrust of the chain-feed rig at similar weight — for sites where the feed isn't lying in mud. A 2.2 m feed places the rig into very tight spots.
130–1,460 Nm
Pick your motor
Eight single-speed motors from 3.0 to 32 cubic inch give a torque range of 130 to 1,460 Nm and speeds from 1,000 rpm down to 100 rpm — matched to the hole, not fixed.
225 mm
Light augering
Depending on the head fitted, the fully hydraulic system will carry out light augering up to 225 mm diameter, as well as diamond drilling.
92 kg
Mast weight
The mast is 92 kg, the 13 hp Honda power pack 89 kg and the console 35 kg — light enough to raise on scaffolding or in an elevating work platform.
