This standard specifies the type, basic parameters, technical requirements, safety requirements, completeness, testing and test methods, inspection rules, marking, packaging, transportation and storage of general suspension conveyors. This standard applies to general suspension conveyors that use detachable chains as traction components and I-beams as tracks (called heavy-duty) and double-hinge links as traction components and open square tube special-shaped steel as tracks (called light-duty). Accumulation-type suspension conveyors and other types of general-purpose suspension conveyors can also be used as a reference.
