Epiroc says it is accelerating the transformation towards more productive and sustainable mining operations with the introduction of the new Minetruck MT22, a new 22-tonne underground truck designed for mining operations with small drift sizes.

The Minetruck MT22, which succeeds Epiroc’s smallest underground truck, the Minetruck MT2200, is built to deliver increased effectiveness, reduced exhaust emissions, lower fuel consumption and extended service intervals, Epiroc says.

Prerna Devkar, Global Product Manager Minetruck Small Segment, said the MT22 retains the same exterior design as the MT2200, but introduces several key upgrades, most notably the Stage V engine option and European Conformity certification.

Equipped with the Cummins QSL9 Stage V engine that is designed for high power and torque, the Minetruck MT22 features an advanced after-treatment system that significantly reduces harmful emissions such as particulate matter and nitrogen oxides, Epiroc says, improving underground air quality without compromising performance.

Additional advantages of the Stage V engine include lower noise levels, 5% more fuel efficiency (dependng on each duty cycle), and 100% extended oil change intervals (from 500 to 1,000 hours), reducing maintenance needs and operational downtime. These enhancements contribute to a more comfortable and efficient mining experience while ensuring compliance with global standards and regulations, Epiroc says.

“In addition to the Stage V engine, the new Minetruck MT22 offers other engine variants, including China IV and Tier III, giving customers the flexibility to choose based on their specific needs and preferences,” Prerna added.

The Cummins QSL9 Stage V engine is now available globally as an option for the Minetruck MT22. Epiroc also offers Stage V engines for the models including the Scooptram ST1030, Scooptram ST14 S/SG, Scooptram ST18 S/SG, Minetruck MT42 S/SG, Minetruck MT54 S, and Minetruck MT65 S.

All of Epiroc’s underground trucks and loaders are compatible with HVO100, a renewable biodiesel alternative. This further reduces greenhouse gas emissions and pollutants while enhancing engine performance and longevity.

Beyond the engine upgrade, the Minetruck MT22 incorporates several improvements over its predecessor, such as an integrated load weighing system and an optional three-point seatbelt – both aimed at boosting productivity and enhancing safety in mining operations.
