London, 16 May 2024, (Oilandgaspress) –Komatsu is introducing the second generation of the company’s Z2 product line of small-class development drill and bolting equipment with unique enhancements and additions, including the first battery-electric offerings within Komatsu’s underground hard rock portfolio, an innovative pumpable resin system solution, optimized ergonomics and more.
The small-class ZJ21 jumbo drill and ZB21 bolter initially launched in 2020 with a common platform. The new Z2 bolters and jumbos also feature optimized operator ergonomics designed to maximize comfort and visibility, user-friendly intuitive controls and engineering for ground-level maintenance.
The second generation ZB21 is a small-class bolter featuring a fully enclosed ROPS/FOPS-certified operator cabin, intuitive operator controls, integrated patented screen handling and industry-leading drifters manufactured by Montabert.
The bolter also introduces an optional Komatsu pumpable resin system using J-LOK P by Jennmar. The unique solution allows resin to be pumped into the drilled hole prior to bolt installation, permitting the use of more economical bolts and helping to decrease overall installed cost.
The second generation ZJ21 jumbo drill is a single-boom development drill with a fully enclosed ROPS/FOPS-certified operator cabin, innovative drilling feeds, advanced pilot hydraulics and renowned drifters manufactured by Montabert.
Both product lines now include battery-electric versions featuring Komatsu’s innovative approach to BEV with onboard, smart, opportunistic charging and designed for seamless integration and compatibility with existing mine infrastructure. The ZB21 and ZJ21 are the smallest size-class drills and bolters to offer a BEV option and feature a modular battery driveline with 83kWh of onboard energy designed for demanding tram cycles and the challenges of hard rock mining.
