Angle problems of webbing sling during lifting

The angle problem is involved in the lifting process of the two webbing slings, and this angle cannot be avoided.

Because during the lifting process, it is necessary to consider fixing two webbing slings from both ends, while lifting only one lifting point, the lifting angle is unavoidable.

In the lifting method we described earlier, there are two ways to fix the lifting belts, namely the straight lifting method and the knot method.

It is the same as the lifting and fixing method of a lifting strap. Only the two webbing slings are stressed, and the lifting angles are different.

The two lifting straps are lifted at an angle difference of 45° and 45°-60°

Straight lifting method: The 45° tensile force is 1.4 times the normal breaking load, that is, the maximum carrying capacity of two one-ton lifting belts is 1.4 tons;

The 45°-60° tensile force is 1.0 times the normal breaking load, that is, the maximum carrying capacity of two one-ton webbing sling is 1.0 tons;

Noose method: 45° tensile force is 1.12 times the normal breaking load, that is, the maximum load capacity of two one-ton lifting straps is 1.12 tons;

The 45°-60° tensile force is 0.8 times the normal breaking load, that is, the maximum carrying capacity of two one-ton lifting belts is 0.8 tons;

Note: M = coefficient of symmetrical load, installation tolerance of lifting belt or lifting belt parts: 6 ° in the vertical direction.

The maximum working load of a hoisting belt has a great relationship with the hoisting method. Different hoisting angles have a different maximum of hoisting working loads.
