electric chain hoist

Matching bearing capacity with tonnage
Double chain has stronger load-bearing capacity: Double chain is supported by two chains in parallel, with significantly higher load capacity than single chain. Typically, double chain or multi chain designs are used for sizes of 3 tons or more.
Single chain is suitable for light lifting: Small gourds weighing 1 to 2 tons are often equipped with single chains to meet the light lifting needs of general warehouses or factories.
Difference in safety margin: Some double chain models have a higher safety margin through mechanical synchronization control to prevent load shaking. ‌‌
Lifting speed and operating experience
Faster single chain speed: Under the same power, the operating speed of single chain mode is usually faster, for example, some models can reach a single chain speed of 8 meters per minute.
Double chain speed halved: In order to balance the force, the double chain mode runs at about half the speed of a single chain, such as 4 meters per minute, but lifts heavy objects more smoothly.
Convenience of operation: The single chain structure is relatively simple, making operation more convenient; The double chain structure is complex, and attention should be paid to chain synchronization. ‌‌‌
