Safety Precautions For Lifting Sling For Prefabricated Stairs

BY ADMIN | 15-04-2022

  1. The selection specifications of steel beams, rope buckles, steel wire ropes, and lifting rings should be determined by force calculation. The connection between the lifting sling and the tower crane hook and the prefabricated stairs should be tight, and the wire rope and the lifting ring should be tied firmly. The force should be uniform and balanced.

  2. The lifting hook and lower hook of the tower crane should be stable to prevent emergency braking. Both the driver and the signal conductor should be certified to work, and the signal should be accurate and uniform.

  3. During the hoisting process of prefabricated stairs, it is strictly forbidden to stand under the components to ensure construction safety.

  4. When the concrete strength of the cast-in-place platform does not reach the specified design strength, the bottom formwork support system shall not be removed.

  5. In the weather conditions such as foggy days, rainy days, and wind power greater than grade 6, the hoisting of prefabricated stairs should be stopped.
