Description
Whether it is chain block or electric chain hoist, the lifting chain is standard G80 grade, using carburizing quenching, galvanizing, blackening, electrophoresis and other processes, common Φ7.1mm, Φ11.2mm and so on the different diameter sizes, in addition to 3mm, 5mm, 6mm, 8mm, 10mm, 12mm, etc. (according to the lifting chain chain chain chain hoist to choose the corresponding specifications).
The tensile strength is more than 800N/mm². Chains of different sizes and strength levels have different load ratings to meet different lifting capacity requirements from 0.5t to 50t or even heavier. Remember to use chain oil when replacing hoist chains or for maintenance.
Breaking force: 4 times
Length: 3m/6m/9m/12m etc. (according to the lifting height of the chain hoist)
Tolerance: Each chain ring is controlled within the standard error, which can be verified by actual measurement.
Material: 20Mn2
