Komatsu launches PC78US-11 new excavator with greatly upgraded performanc

high performance

This excavator is equipped with a newly developed 3-cylinder 2.4L high-output engine, achieving significant performance upgrades. Compared with traditional machines, its work efficiency is increased by 23% (when loading a 90° dump truck in P mode), and its taxiing speed is also increased by 18%. What's more worth mentioning is that due to the enhanced stability, the maximum rated load of the jib crane has been significantly increased from the original 1.7 tons to 2.3 tons. In addition, attachment traffic has increased by 12%, making using various attachments smoother. More importantly, it is not equipped with a DPF, thus eliminating the trouble of regular maintenance.

Ultra low noise

By improving the engine room and other structures, this excavator reduces environmental noise by 5.2dB(A), achieving the top ultra-low noise level among 7-ton hydraulic excavators. This makes it very suitable for urban construction and night construction, providing operators with a more comfortable and safer working environment.

High functionality

To improve work efficiency, we adopted a newly designed blade shape that reduces soil spillage. At the same time, a convenient switch is installed on the top of the blade bar. The operator can switch the operating speed between Hi and Lo with just one press, which greatly improves work efficiency while driving. In addition, it also comes standard with configurations such as LED lights, rear monitoring system, and suspension seats, which further enhances operational safety and comfort.
