Hardcore design without fear of challenge
The core competitiveness of the NT855 stems from its solid mechanical structure.The combination of cast iron cylinder block and wet cylinder liner endows it with extremely high torsional rigidity and heat dissipation efficiency, maintaining stable output even under extreme high load conditions.The four-valve-per-cylinder configuration optimises intake and exhaust efficiency, and with the classic PT fuel system (Pressure-Time Fuel Supply Technology), it achieves precise fuel injection control, balancing power and fuel economy.Its 15-litre displacement delivers up to 450 hp, with a smooth and consistent torque curve, making it particularly suitable for scenarios that require long periods of high load operation.
All-weather adaptability for versatility in the industry
Whether it's a hot desert mine, a humid harbour terminal or a bumpy construction site, the NT855's modular design and redundant cooling system can handle it.It has been used to power mining trucks, generator sets, fire pumps and even railway locomotives.What's more, the NT855 is maintenance-friendly: the clear layout of key components and the abundant supply of standardised parts significantly reduce maintenance costs and the risk of downtime, making it a "safe choice" for equipment in remote areas.
A classic by reputation
Despite the constant evolution of modern engine technology, the NT855 is still retained by a large number of people around the world due to its "simple and reliable" gene.Many equipments that have been running for decades are still equipped with original NT855, and its low failure rate and long service life are called "the iron ox that never stops" by users.The perfect after-sales network and continuous technical support of Cummins make this classic model to have a long-lasting vitality in the new era.
The Cummins NT855 is not a "performance monster" that pursues extreme parameters, but a doer that defines the industry standard with practicality.With more than half a century of global verification, it has interpreted the true value of "heavy-duty power" - providing the most trustworthy answer in the most demanding environment.
