The reason why lifting belts are so reliable is inseparable from their safety factor. Safety factor is a direct manifestation of the quality problem of lifting belts. A higher safety factor can greatly improve the safety of lifting operations. Currently, the safety factor of lifting belts from regular manufacturers can generally reach more than 6 times. What kind of concept is this?

Before leaving the factory, lifting belts need to undergo strict testing, and all relevant data of lifting belts are not groundless, but obtained through a series of rigorous tests. Almost every lifting belt manufacturer will be equipped with technologically advanced tension machines to conduct tensile tests on lifting belts, in order to obtain their ultimate bearing value.

Fix the two ends of the lifting belt on the tension machine, and the tension machine continuously applies tension to the lifting belt. The increase in tension will be fed back to the database of the backend computer. As the lifting belt breaks, the tension will disappear instantly, and the value will stop jumping. This value is the ultimate bearing capacity of the lifting belt.

Taking a lifting belt with a rated load of 3T as an example, we test a lifting belt with a rated load of 3T. If the force when it breaks is about 20T, it indicates that the lifting belt is a qualified product, which follows a safety factor of about 6 times. This is the concept of a lifting belt with a safety factor of 6 times.
