(1)Bulk Material Industry

Donghua bulk material conveying chain has been widely used in the core giving equipment in cement, mine, coal, and other fields, such as cement equipment, mine getting equipment, coal conveying equipment, stacking and fetching equipment, etc.


● Excellent material selection and precision manufacturing, especially suitable for large impact load, high temperature and dust, and other particular environments, providing system solutions for various occasions where bulk materials are used.

● The chain with a particular sealing structure has long service life and low maintenance. It has been applied to stacker-reclaimer equipment in cement plants, steel mills, thermal power plants, and other dusty environments.

Main products:

Stacker and reclaimer chain, hoist chain, scale conveyor chain, zipper machine chain, sprocket, and various accessories.

(2)Construction Machinery Industry

Chains used in the construction machinery industry mainly include driving chains and conveying chains used in construction machineries such as pavers, excavators, loaders, bulldozers, scrapers, mining/coal mining machinery, concrete machinery, and port machinery, and drilling rigs.


The working environment in various fields of the construction machinery industry is rather harsh, which requires the chain to have the characteristics of high strength, high wear resistance, corrosion resistance, high temperature, low-temperature resistance, etc. Donghua developuniqueal chain drive products for construction machinery under different working conditions to meet its requirements.

● Chain for pavement machinery: the driving chain has high fatigue resistance, and the conveying chain has high tensile strength and wear resistance.

● Chain for skid steer loader: High fatigue resistance, impacts, and wear resistance.

Main products:

Chains used in the construction machinery industry: large-size roller chains and high-strength chains for driving; Long pitch conveying chains, lifting chains, etc.

Chain for skid steer loader: high strength chain, etc.
