Main Shaft Construction
The Rock Drill R405 Drill Rig is a low-headroom, restricted access drilling unit with a remote power unit. The remote power unit can be placed up to 200 ft away from the rig with umbilical hoses.
With the high torque JT200 Series Drill Head the Rock Drill R405 is a powerful and compact drilling unit for micro piling and limited access drilling applications.
INNOVATIVE SIMPLICITY
With their own practical drilling experience the Mincon Rock Drill engineers used innovative simplicity to design a series of drilling units that were easy to maintain and service. This engineering methodology designed a series of machines that are built to last:
Engineered simplicity also means components are stronger and more durable.
Maintenance requirements are reduced with fewer wearable items and moving parts.
Off-the-shelf parts and spares can be utilized from local suppliers, Lowering maintenance and operating costs.
The Rock Drill R405 is a powerful, restricted access drill rig for low head room applications.
