Selection of Aluminum Alloy Hand Chain Hoist Chains: Chain Types: 1. Calibrated Chain (Calibrated Chain) - The chain ring size tolerances are strict, ensuring proper engagement with the hoist sprocket to prevent jumping or jamming. Hand chain hoists must use calibrated chains! Ordinary welded chains can lead to equipment damage due to insufficient precision. 2. Surface Treatment: - Galvanized Chain: Rustproof, suitable for humid and outdoor environments (such as ports, construction sites). - Blackened Chain (Oxidation Treatment): Basic rustproof, suitable for dry indoor environments. - Stainless Steel Chain: Strong corrosion resistance, used in special places such as food and chemical industries (note that the strength may be lower than G80). Therefore, aluminum alloy hand chain hoist chains are generally selected to use galvanized lifting chains.
