Introduction and Use of Lifting Belts

1. Product performance characteristics: Synthetic fiber lifting belt (hereinafter referred to as lifting belt) is lightweight, soft, with high safety factor, long service life, non-conductive, and has no electric shock hazard. It has advantages such as good corrosion resistance and is gradually replacing wire rope and chain slings.

2. Main uses and scope of application:

(1) Lifting belts are mainly used in mechanical processing, port loading and unloading, shipbuilding, power installation, transportation, aerospace and other fields.

(2) The load range of the lifting belt is 1T-1000T

3. Product working conditions:

(1) The ambient temperature for the use of lifting belts is -30 ° C -+100 ° C. When using polypropylene lifting belts, the ambient temperature is generally -40 ° C -+80 ° C. It is strictly prohibited to use them in high temperature environments.

(2) When synthetic fibers are exposed to ultraviolet radiation for a long time, their strength will decrease, so lifting straps should not be used in areas with strong ultraviolet radiation for too long.

(3) Lifting straps should avoid lifting operations in molten metal, acid, glass panels, fragile items, nuclear reactors, and special environments.

4. Installation and debugging

(1) When using the lifting belt, hang it directly into the center of force on the hook and not directly on the tip of the hook

(2) When using two lifting straps, hang them directly into the double hooks, and hang each lifting strap at the symmetrical force center position of the double hooks

(3) When using four lifting straps, each two lifting straps should be directly hung into the double hooks, and attention should be paid that the two lifting straps inside the hooks should not overlap or compress each other. The four lifting straps should be symmetrical with the force center of the hook,

(4) When lifting with two lifting belts and lifting with four lifting belts, the length error is not subject to special requirements. The allowable deviation of its nominal length should not exceed the provisions of the lifting belt standard.

(5) Calculation coefficients for the lifting angle and ultimate working load of multiple lifting belts

(6) Before use, the lifting belt must be tested for lifting before lifting, and the lifting point should be selected on the same lead weight line as the lifting center.

(7) The lifting belt and the ring sleeves and metal accessories at both ends of the lifting belt must have sufficient curvature radius.

(8) During use, it is prohibited to tie or use knotting methods to connect the lifting belt. Special connectors should be used to connect the lifting belt.
