"Understand lifting safety in 3 minutes"

Q1 How to prevent "tail swing" accidents during lifting?

✅ Correct solution:

1. The height of the lifting point is greater than 2 times the height of the cargo

2. Install a traction rope control for long cargo

3. When the wind speed is ≥12m/s, the anti-sway algorithm is enabled (mandatory requirement of the new national standard GB/T 3811)

Q2 When must the wire rope be scrapped?

⚠️ Self-check tips:

- 6 broken wires: 6 broken wires within 1 twist pitch

- 10% weight loss: diameter wear > 10% of nominal diameter

- Flattening deformation
