NEW MOTORS. REBUILDS. PARTS.
German engineered by AT-Boretec. Supplied and supported in Australia by JB Trenchless.
When a rockmotor housing goes, the rig stops.
Sometimes a rebuild brings it back. Sometimes it’s had enough and you need a new one. Either way you’re off the job while you work out which — and that’s the expensive part, not the motor.
WORTH DOING: RUN A SPARE
The contractors who never lose days to a rockmotor are the ones running two — one on the rig, one on the shelf.
When the first one lets go, you swap it over and keep drilling. The failed housing goes in for a rebuild on your schedule, not in a panic. No scrambling, no crew standing around, no hire rig while you wait.
