DOUBLE & TRIBLE LINKS DROP RORGED CHAIN
It refers to a chain with double or three-chain structure. This chain usually has high strength and wear resistance, suitable for the need to withstand large tension and impact occasions.
Application：
Industrial field: Forging chain is widely used in mining, metallurgy, cement, chemical and other industries of machinery and equipment, as transmission, conveying and connecting parts.
Agricultural field: In agricultural machinery, forged chains also play an important role, such as harvesters, threshers and other equipment in the transmission chain.
Transportation field: In the field of transportation such as railways, highways and aviation, forged chains are also used in the transmission system and suspension system of vehicles.
