2024 Komatsu Underground Hard Rock Drills ZJ21B

Exceptional flexibility and innovation in a common platform

Designed for flexibility and productivity, the ZJ21 is a jumbo drill on a common-carrier platform that makes operator training and adoption on the controls easier and faster. The ZJ21 also offers excellent useable coverage in a small jumbo platform.

The ZJ21B offers a battery-electric driveline option with identical capabilities and features as the ZJ21 model. This electric drilling rig features a modular battery driveline with 83 kWh of onboard energy for the most demanding tram cycles and challenges of underground mining.

Features may include:

• The ZJ21B drill rig is operated on battery power, which supports our customers on their journey to electrification and sustainability. It features a modular battery driveline with 83 kWh of robust onboard energy for less charging time.

• Leverages preexisting Komatsu technology for a system designed to boost productivity. The electric ZJ21B features Komatsu’s innovative approach to BEV — onboard charging, smart opportunistic charging and 100% compatibility with existing infrastructure.

• Auto-paralleling gives you 100% accuracy across the face with a maximum of ~1 degree error. Fast cycle times with less setup between holes for increased productivity.

• Hydraulic pilot control system with universal drilling and bolting layout. Intuitive, common controls offer advantages in operator adoption, training and performance, as well as maintenance benefits.

• Lightweight, durable and cost-effective drilling feed delivers superior drill performance and reduced daily maintenance.
