  • Covering major brands and offering both in-stock and customized products——Yiyan Machinery’s “original equipment manufacturer (OEM) precision” parts secured bulk purchase and matching intentions at a top-tier exhibition author
  • 26th December 2025

In 2025, we showcased our full range of core construction machinery components (covering precision parts such as excavator hydraulic pumps/valves, pistons, and gears) at the leading domestic construction machinery aftermarket exhibition – the China Excavator Parts & Construction Machinery Exhibition.

As a professional exhibition focusing on excavator and construction equipment parts in China, it gathers over 80% of the country’s construction machinery dealers, repair service providers, and OEM manufacturers. Our on-site display of PC400-7 and other compatible parts, with their advantages of “original factory precision + high cost-effectiveness,” facilitated bulk purchasing needs from over 20 regional dealers and secured cooperation intentions from 3 OEM manufacturers.

This exhibition is a microcosm of Yiyan Machinery’s “precise layout and close proximity to end users” in the domestic construction machinery aftermarket – our parts cover mainstream excavator brands (Komatsu, Caterpillar, Hitachi, etc.) and can provide both spot and customized supply.
