Tough sites demand tougher parts. JOC supplies buckets, cutting edges, undercarriage components, hydraulic fittings, housings, and structural fabrications for excavators, loaders, and cranes. As a leading China manufacturer and supplier, we combine wear-resistant steels, precision machining, and protective coatings to keep machines productive in dust, shock, and weather. Start at Home for a quick overview and message our team through Contact Us to spec your kit.
Why choose JOC for construction equipment?
We engineer for impact and abrasion. Heat-treated boron steels for edges, manganese steels for high shock zones, and robotic welds with NDT verification ensure long life. Dimensional jigs secure interchangeability across batches, while coating systems fight corrosion on coastal or chemical sites.
How is performance validated?
Through destructive and non-destructive tests, simulated load cycles, hardness mapping, and fit checks on fixtures. We document it all so your QA can sign off confidently. **Let’s build the parts your fleet deserves—**reach us via Contact Us.
