The hand chain hoist is a G80 lifting chain. It has high strength and large pulling force, suitable for lifting and hoisting operations. It is used in hand chain hoists, hand winches, and electric hoists because of its standard pitch that smoothly prevents jamming. The 'G' stands for grade, which in the context of chains means that the test load per square millimeter of the radial cross-section of the chain links is 80 kilograms. The material used is 20Mn2 alloy structural steel, which, due to its appropriate hardenability, can achieve high tensile strength after proper metal heat treatment.
