The construction industry is accelerating its transition toward low-emission equipment, but one thing remains unchanged—every heavy machine still depends on reliable wear parts to maintain productivity. A recent milestone is the deployment of the world’s first serial-produced Volvo A30 Electric articulated haulers by Norwegian contractor LNS at the Hemsil 3 hydropower project. The zero-emission machines will be used to construct an approximately 20km tunnel, supporting one of Norway’s major renewable energy developments.
Hydropower and tunnel construction projects require continuous excavation, hauling, grading, and material transportation. Alongside electric articulated haulers, contractors rely on crawler excavators, bulldozers, compact track loaders, and other heavy machinery to complete earthmoving and underground construction. Although powertrains are changing from diesel to electric, the demand for durable undercarriage systems remains as important as ever.
Projects such as Hemsil 3 place equipment under demanding conditions, including rough terrain, abrasive rock, steep gradients, and long operating hours. These environments accelerate wear on critical components such as track chains, track rollers, top rollers, bottom rollers, idlers, sprockets, steel tracks, rubber tracks, and track adjusters. Whether powered by diesel or electricity, crawler machines require high-quality replacement parts to maintain uptime and reduce maintenance costs.
The adoption of electric construction equipment also reflects a broader industry trend toward sustainable infrastructure. Zero-emission machines are becoming increasingly popular in tunnels and enclosed work areas because they reduce exhaust emissions and improve working conditions for operators. However, contractors still need reliable undercarriage components capable of handling heavy loads and continuous operation throughout multi-year infrastructure projects.
For fleet owners, choosing OEM-quality excavator and bulldozer undercarriage parts is essential. Heat-treated steel, precision machining, durable sealing systems, and stable product quality help extend service life and minimize unexpected downtime. Fast delivery and a dependable supply chain are equally important for keeping projects on schedule.
We supply excavator and bulldozer undercarriage parts for mining, hydropower, tunneling, railway, port, energy, and infrastructure projects worldwide. Our product range includes track chains, track rollers, idlers, sprockets, steel tracks, rubber tracks, track adjusters, and travel motors. All products are manufactured to OEM-quality standards and designed to deliver reliable performance in demanding construction environments.
As electric and conventional construction equipment continue to work side by side on major infrastructure projects, the need for durable undercarriage systems will continue to grow. High-quality replacement parts help contractors improve equipment reliability, reduce operating costs, and maximize productivity throughout the project lifecycle.
