Get to Know Corbay: 18 Years of Kobelco Excavator Parts Expertise
If you run, repair or resell Kobelco excavators, you have probably spent hours hunting for the right part — the right liner kit, the right hydraulic pump, the right controller — at the right price, with someone you can actually trust on the other end of the line. That is exactly the problem Corbay Excavator Parts was built to solve.
Corbay is the international trading brand of Shenyue Machinery (Guangzhou Shenyue Machinery Technology Co., Ltd.), a Chinese company that has specialized in Kobelco excavator parts for nearly two decades. Same warehouse, same technical team, same quality standards — with a dedicated global focus.
From Repair Bench to Global Supply Chain
Our founder, Mr. Chen Jianguo, did not start in an office. He started on the workshop floor. From 2002 to 2007, he worked at Kobelco — moving from after-sales service to warehouse supervisor to regional supervisor. Five years of touching, testing and tracking real parts gave him something rare in this industry: an insider's understanding of what a "genuine, reliable part" actually means.
In 2007, he left Kobelco to start his own parts trading business. In 2011, the Shenyue brand was officially launched. As the customer base grew beyond China's borders, we established Corbay as our dedicated international brand — to serve overseas distributors, repair shops and fleet owners with the same supply chain that has kept Shenyue's domestic customers loyal for years.
