en.Wedoany.com Reported - Komatsu Australia is upgrading the aftertreatment systems for its construction and mining equipment, launching multiple non-Tier 4 models that do not require diesel exhaust fluid, to meet emission regulations across different markets including Australia, New Zealand, New Caledonia, and Papua New Guinea.

For companies operating across multiple jurisdictions, complying with local legal, environmental, and safety standards is a fundamental requirement. Komatsu Australia's construction operations cover New Zealand, New Caledonia, and Papua New Guinea, each with varying compliance requirements, which previously limited the types of equipment that could be deployed.

Mark Boyes, National Development Manager for Construction at Komatsu Australia, stated that by introducing non-Tier 4 models, the company can now provide equipment with enhanced features such as integrated machine control across the Oceania market, bringing previously inaccessible technology to traditional markets.

The new series models retain the same chassis and core components as their Tier 4 counterparts while simplifying the aftertreatment system, eliminating the need for diesel exhaust fluid (DEF), thereby reducing maintenance costs and minimizing downtime.

The newly launched WA380-8 wheel loader is suitable for various loading applications such as concrete mixing, log handling, and waste recycling, and comes standard with remote monitoring and positioning systems. Meanwhile, the PC138US-11 excavator is designed for civil construction, earthmoving, and utility applications, with a short tail swing structure enabling efficient operation in confined worksites.

Mark Boyes stated that these machines will accelerate Komatsu Australia's growth in both domestic and international markets. In 2026, Komatsu Australia plans to launch more non-Tier 4 models across various markets while retaining the Tier 4 product line to meet diverse customer needs. "We want our customers to use the latest machines without compromise," he said.
