Meet Corbay: 18 Years of Kobelco Parts Expertise

If you operate, repair, or resell Kobelco excavators, you have probably spent hours hunting for the right part — the liner kit, the hydraulic pump, the controller — at the right price, from someone you trust. 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 specialising in Kobelco parts for nearly two decades. The same inventory, the same technical team, the same quality standards — with a dedicated global focus.

From the Repair Bench to the 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 served at Kobelco — from after-sales service to warehouse manager and then regional supervisor. Five years of touching, testing and tracing real parts gave him something rare: an insider's understanding of what a 'genuine, reliable part' really means.

In 2007 he left Kobelco to start his own parts trading business. In 2011 the Shenyue brand officially launched. As the customer base grew beyond China, we established Corbay as our international brand — to serve distributors, workshops and fleet owners overseas.
