Excavator-Mounted DTH Drilling Rig for Rock Drilling

Description

The Excavator-Mounted DTH Drilling Rig is a rock-drilling attachment intended for use with a compatible excavator. It allows contractors to consider an excavator-based drilling arrangement for projects requiring holes in rock, with the carrier providing mobility and positioning for the attached drilling equipment. Down-the-hole drilling uses a percussion hammer positioned close to the drill bit. In a conventional pneumatic DTH system, compressed air powers the hammer and assists with removing cuttings from the hole, while the drilling assembly provides rotation and feed. The exact hammer configuration, air requirements and hydraulic requirements must be confirmed for this model. An excavator-mounted arrangement can help teams position drilling equipment at different locations across a work area. Its usefulness depends on the excavator’s reach, stability, attachment interface and ability to supply the required hydraulic flow and pressure. Correctly matching the drilling rig to the carrier is therefore an essential part of selecting the equipment. This type of drilling attachment can be considered for rock excavation preparation, quarry drilling and selected construction activities. Hole diameter, drilling depth, rock conditions and the required drilling angle all influence whether a particular configuration is suitable. These requirements should be checked against the supplier’s technical data before choosing the attachment, hammer and drill tooling. For contractors expanding their drilling capability, the rig offers an attachment-based equipment option to evaluate alongside a dedicated drilling machine. The complete operating package may require a compatible excavator, an external air compressor, drill rods, a DTH hammer, drill bits and connecting hoses. The supplier should confirm which components are included and which must be purchased separately.
