KOMATSU - KOMATSU Parts Catalog Lookup. KOMATSU, founded in 1921 in Komatsu City, Japan, is one of the world’s leading manufacturers of construction and mining machinery. The company was originally established by Meitaro Takeuchi to create job opportunities for the local community following the closure of a nearby copper mine—reflecting KOMATSU’s longstanding commitment to social responsibility and sustainable development. Starting from basic mechanical production, KOMATSU has grown over the past century into the world’s second-largest construction equipment manufacturer. Its core product lineup includes bulldozers, excavators, wheel loaders, and large-scale mining equipment. The company is widely known for its emphasis on technological innovation and automation, having developed autonomous mining trucks, underwater electric dozers for extreme conditions, and even conceptual machinery for lunar construction tasks. KOMATSU’s brand philosophy, “Creating Value Together,” highlights its focus on building long-term, mutually beneficial relationships with customers, partners, and society at large. By combining global R&D with localized manufacturing and support, KOMATSU continues to strengthen its leadership in the heavy equipment industry.
