Electric hoists represent their own machinery, strength, and toughness, while the stage is elegant, flowing, and soft, with conflicts and collisions between the two.

Product Details

The shape design of the chain links of the small stage hand chain hoist occupies a core position in the fatigue performance of the stage hand chain hoist, and its rationality is directly related to the service life and operational safety of the equipment. For the chain of the stage hand chain hoist, the adoption of a closed-loop structure with arc transitions for the chain links is an optimized solution verified by long-term practice. This design fundamentally avoids the fatal flaw caused by right-angle or acute-angle designs — stress concentration.

Stage Hand Pulling Gourd Product Details

During the operation of the stage, the chain of the small stage hand chain hoist needs to repeatedly bear the pulling force of lifting heavy objects. If there are right angles or acute angles in the chain links, the transmission of force will form a "bottleneck" here, leading to a sharp accumulation of stress. With the increase in the number of lifting operations, this concentrated stress will be like a hammer constantly hitting the same position, causing micro-cracks to gradually form in the metal material, and then triggering fatigue fracture of the chain. This undoubtedly brings great potential safety hazards when carrying key equipment such as stage lighting and large backdrop panels. However, the closed-loop structure with arc transitions can allow the force to be evenly transmitted along the arc surface of the chain links, dispersing the stress to a larger area and significantly reducing the "impact" intensity borne by local parts of the small stage hand chain hoist.
