8 non-welded chain hoists
1 Scope
This standard specifies the eight non-welded chain hoists (including 1,2,3,4 limb chain hoists) ratings and technical requirements and test methods for the calculation of the crane
Equipped with chain in line with GB/T 20946 and GB/T 8 chains of grade and the appropriate level of 24816 components.
This standard does not apply to welded chain hoist (see GB/T 20652), chain hoists limb length ranging from hanging chain, hanging chain or cyclic particular purpose.
