Tier4 Final Compliant Models Released

Independent Practitioner's Assurancecheckmark

In 2016, Komatsu released one vehicle model after another that greatly reduce nitrogen oxide (NOx) and particulate matter (PM) emissions that meet Japanese (Emissions from Non-Road Special Motor Vehicles 2014 Standards), North American (EPA Tier4 Final), and European (EU Stage IV) emissions controls for Hydraulic Excavators, Bulldozers, Dump Trucks and Wheel Loaders. These models are equipped with newly developed next-generation engines that result in construction machinery that are clean and fuel efficient, with excellent durability and reliability.
Below are some examples.

Medium-sized Hydraulic Excavator "PC220(LC)-11/PC230(LC)-11"

PC220-11
PC220-11

With "Quality and Reliability" as the foundation, Komatsu has pursued ever high levels of quality in environmental, safety and ICT aspects, and released the Non-Road Special Vehicles 2014 Standards compliant "PC220(LC)-11/PC230(LC)-11" models to the market. These models greatly reduce the emissions of nitrogen oxide (NOx) and particulate matter (PM) have next-generation engines that meet the Non-Road Special Vehicles 2014 Standards. In addition, with the further development of Total Vehicle Control, which provides optimum control of the vehicle's main unit, and with the usage of the auto idle stop function, we achieved high levels of both productivity and fuel economy performance, and reduced the fuel consumption rate by approximately 5% compared to our previous models (PC220(LC)-10/PC230(LC)-10). (Based on in-house test standards)
