Elevator chain products have high requirements on wearing resistance and tensile strength. For this purpose, we carry out secondary heat treatment for the rollers and bushings. The two chain components are firstly carburized, and then undergo secondary heat treatment to offer increased surface hardness and core part toughness. These processes ensure improved crushing strength.

As this range of roller chain is primarily used for material lifting in vertical direction, there is a high requirement on its framework firmness so as to prevent the chain getting loosening up. To meet this requirement, we manufacture the product parts with optimized allowance to ensure prefect match, and meanwhile, a hydraulic press is applied to assemble the chain components.

Our elevator chain is commonly used in cement, mining, grain processing, road construction, and steelworks industries. It assists material elevating, and is accommodate to severe working environments. It works normally even if it is attached with heavy dust and hard particles.
