The Komatsu PC400 excavator is renowned as one of the most productive machines in the world, with the capability to move materials and dig at speeds of up to 400 cubic meters per hour. It boasts a digging depth of up to 7.68 meters and a loading height of up to 7.62 meters. Few machines are better suited for large-scale construction and mining projects.
Founded in Japan in 1921, Komatsu has maintained its position as a leader in the construction and mining equipment industry. One of the company’s latest innovations is the development of unmanned excavators.
Komatsu is committed to environmental sustainability, focusing on reducing harmful emissions and utilizing renewable materials in its manufacturing processes.
The versatile Komatsu PC400 excavator is widely used for tasks such as digging pits, trenches, and canals, mineral extraction and moving rock, excavating foundations, dismantling old buildings, and preparing construction sites. It’s also employed for creating cuts and fills, laying pipes and drainage systems, and loading and unloading materials like gravel, sand, and soil.
When equipped with a hydraulic hammer, the PC400 excels in breaking hard rock during mineral extraction and demolishing concrete structures during building dismantling. It is also utilized in earthworks, creating reservoirs, and park landscaping.
