Equipment profile

Built around the project configuration

The EPIROC FlexiROC D50 is a crawler-mounted down-the-hole rig for quarry production, aggregate extraction and supported surface-construction drilling. Its 90–130 mm hole range, high-pressure onboard air and 4- or 5-inch hammer configurations provide a focused platform for straight, repeatable blastholes.

A carousel tube handler supports multi-pass drilling to 45 m, while the standard feed can complete holes up to 5.4 m in one pass. The oscillating undercarriage, enclosed ROPS/FOPS cabin, pressure-regulated breakout table and toe-hole capability equip the rig for repeated bench work across changing site conditions.
