Komatsu crawer excavator PC70-8


Komatsu is the world's second largest supplier of construction and mining equipment, after Caterpillar. However, Komatsu has a larger market share than Caterpillar in some regions such as Japan and China. The company currently has many factories and branches in Japan, Asia, America and Europe and is still planning to continue to expand.


Komatsu excavator brand originated from Japan, appeared on the market since 1917. It can be said that this is one of the world's leading brands of excavators, currently competing fiercely with rivals. as big as Hitachi or Catterpillar. Komatsu excavator is considered as a machine with high durability, good working performance and common use. Perhaps that is also the reason why Vietnam and other countries around the world are very fond of the Komatsu line.


Komatsu excavators are specially designed for heavy duty applications. With a powerful engine, sturdy boom and bucket design, bearing iron material ensures workability and productivity in all cases. Along with compact structure and superior features, the company's machine can be widely applied such as: bridge construction, road construction, construction work in residential areas. The machine has many working modes with different engine speed and hydraulic system pressure to meet different conditions. In the fuel-saving mode, the machine still works effectively, in the heavy-duty mode, the machine can operate with the largest capacity, helping the digging and lifting force of the machine can be increased many times.
