How to choose the sling strap specifications and the angle of use?


In modern industry, slings are used in a wide range of applications. Lifting straps are required for bundling and handling of goods in many industries. The sling is of good quality, with high tensile strength, anti-corrosion and anti-electricity. It is a very widely used tool in modern industry. Generally speaking, before lifting, everyone needs to choose the specifications and types. During the lifting, we must pay attention to the control of the lifting angle!
1. How to choose the specifications of the sling

The sling is generally used for containers and the goods are bundled and transported. However, in advance, we need to select the specifications of the sling, according to the size, weight, shape and matching of the hoist and sling. Choose a sling with sufficient length and length to meet the usage. If the hoist requires multiple slings, you need to select the same type of sling.
2, lifting belt angle of use

1. When using soft lifting lugs, the minimum length of the lifting lugs should not be less than 3.5 times and the maximum thickness of the hooks in the contact part of the lugs, and the angle of the lifting lugs should not exceed 20°.

2. The sling belt is not allowed to be crossed or twisted during use. It is not allowed to knot and screw. It should be connected with the correct lifting special connecting piece.

Third, the circular hoisting belt ring eye opening angle should not be greater than 20 °, avoid rupture at the ring eye during the hoisting process.

4. When lifting the pipe type object, the correct lifting method should be adopted, and the lifting angle should be less than 60.

5. The contact between the sling and the lifting tool must be constant. Unless the axial width of the sling does not exceed 75 mm, the bending radius of the lifting attachment must be at least 0.75 times the axial width of the sling.
