With rapid industrial development in China, lifting machinery is essential for many operations involving heavy loads at height.
1. Research the manufacturer's reputation and obtain product information in advance. Compare suppliers before purchasing.
2. Visit the manufacturer to verify its qualifications and production capacity before making a purchase.
3. Inspect the appearance. Paint should be even and consistent in color, with no rust. Materials should meet the basic requirements for an explosion-proof hand chain hoist.
4. Have a trained hoist operator perform a trial operation and inspect the chain connections. With no load, manually pulling the chain should produce a clear sound and smooth, free operation.
5. Check dynamic performance under load by raising and lowering within the specified travel range. The load chain must engage correctly with the load sprocket and idler, and the hand chain with its wheel, without jamming. Gear pairs must run smoothly without abnormal behavior, and the load chain must not twist during lifting or lowering. Hand-chain effort should not vary significantly, and the brake must operate reliably for precise, smooth movement.
