The mining industry experienced a surge of innovation in the first half of 2024, marked by the launch of advanced hydraulic excavator models, state-of-the-art technologies, and significant installations.
Komatsu Germany Mining Division (KGM) and SMS Equipment captured attention in May 2024 by launching the PC9000, their largest hydraulic mining excavator yet. This machine, designed to pair with Komatsu’s 830E to 980E mining trucks, promises improved cycle times and reduced material moving costs per ton. Featuring a larger bucket, enhanced digging forces, and extended reach, it is particularly suited for autonomous haulage systems. A redesigned hydraulic system also ensures lower emissions, aligning with sustainability goals.
Peter Buhles, KGM’s vice president of sales and service, emphasized that the PC9000 addresses global surface mining needs, developed with input from customers and distributors worldwide. The first unit will be delivered to a Canadian mining site.
In January 2024, KGM introduced the K-VAD (Valve Adjustment Device) for hydraulic mining excavators. This device boosts safety by enabling remote operation of main and secondary relief valves from the operator’s cabin, eliminating the need for engineers to work near high-pressure areas. The K-VAD kit includes pressure sensors, adjustment motors with tool heads, and is controllable via laptop, tablet, or smartphone. It supports up to six tool heads and monitors up to four pressures, with future updates planned for automation and expansion to additional circuits.
OceanaGold took a significant step towards sustainable mining with the early 2024 introduction of the Hitachi EX3600 electric-hydraulic shovel at their Macraes site in New Zealand. This shovel, powered entirely by renewable energy, dramatically reduces greenhouse gas emissions compared to diesel models. Pieter Doelman, Macraes’ open-pit mine manager, highlighted the shovel’s role in achieving sustainable mining practices, aiming for carbon-neutral operations supported by New Zealand’s renewable energy grid.
In March 2024, Hitachi Construction Machinery (HCM) announced the Operator Assist System for ultra-large hydraulic mining excavators, designed to enhance efficiency and safety. Tested at Rio Tinto’s Australian mine, this system automates loading and digging tasks, easing operator workload and improving productivity. Functions like Loading Assist and Digging Assist optimize operations by monitoring bucket payload and hydraulic cylinder loads.
HCM’s partnership with Rio Tinto demonstrates a commitment to developing practical solutions that enhance safety and productivity. Plans are in place to roll out the Operator Assist System across various excavator models from 2025, following thorough testing and feedback.
These advancements illustrate the mining industry’s commitment to innovation, sustainability, and efficiency, driven by new technologies and sustainable practices.
