The chain of the G80 chain stage electric hoist is enhanced by dual professional processes: specialized quenching and tempering heat treatment + refined surface treatment. Various surface finishes such as blackening, electrophoretic coating, and galvanizing are available according to application requirements, comprehensively optimizing the chain's physical properties and durability.
The heat treatment process effectively improves the internal metal density and toughness of the chain, endowing it with both high strength and excellent impact resistance. When subjected to repeated lifting and lowering forces, the chain avoids brittle fracture, bending, or permanent deformation. It is perfectly suitable for high-frequency, reciprocating lifting operations including pre-performance setup, on-site adjustment during shows, and post-performance dismantling. Even under long-term high-intensity use, it maintains stable performance.
Compared with ordinary low-carbon steel chains, this G80 chain stage electric hoist features significantly enhanced wear resistance. It does not wear thin rapidly despite long-term friction with sprockets and chain guides, effectively extending the overall service life of the chain, reducing the frequency of daily replacements, and lowering the later-stage maintenance costs and downtime losses of stage equipment.
Meanwhile, its fatigue resistance is greatly improved, enabling long-term continuous operation without metal fatigue caused by repeated stress. This ensures stable long-term operation of the equipment and meets the continuous operation demands of touring performances, multiple consecutive rehearsals, large-scale exhibitions, and other scenarios.
