Features

SB160i instrumented boom

Featuring a front wrist structure, the 3 meter telescopic SB160i boom provides 1 meter additional side coverage, extending to 4 meters with telescopic adjustment. It uses a fully-proportional boom control for fast and precise manual boom handling (automated controls available in the Platinum package option).
Ergonomic cabin

The vibration-dampened, FOPS-compliant cabin offers a comfortable, safe operator environment with great visibility, low noise and dust filtration while tramming and drilling.
Superior drilling accuracy

Alpha360 bits and GT38 rods are optimized for the powerful RD535 rock drill to produce greater drilling accuracy at higher speeds. Reduce drilling time and increase advance meters per cycle in your tunneling projects.
