Lifting common sense - lifting belt with large safe working load

In general, a large operating load polyester sling in the range of 0-30 tons, a length in the range of 1-1000 tons, depending on the lifting belt use, safe working load is large different, as follows:

Large safe working load = method coefficient P × rated load

1, vertical crane, large working load = (P) 1 × rated load

2. Tie hanger, large working load = (P) 0.8 x rated load

3, 45 degree crane, large working load = (P) 1.4 x rated load

4, U-type crane, large working load = (P) 2 × rated load

Understand the large safe working load of the lifting belt, allowing you to select small lifting tools such as lifting belts of different tonnage according to the actual situation to avoid the existence of safety hazards.
