Hoisting belt Webbing Slings use what specifications

1. When working with two lifting belts, hang the two lifting belts directly into the double hook. The lifting belt is hung in the symmetrical force center position of the double hook; When the four lifting belts are used, every two lifting belts are directly hung into the double hook. Pay attention to the lifting belts in the hook shall not overlap or squeeze each other, and the lifting belts shall be symmetrical to the force center of the hook.

2. When in use, the lifting belt should be directly hung into the force center of the hook, not on the tip of the hook. Webbing Slings lifting belt is not allowed to cross, twist, knot and twist, and should be connected with the correct special connector of lifting belt. When the load of goods with sharp corners and edges, it is necessary to take sheath, Angle protection and other methods to protect the lifting belt, in order to extend the service life of the lifting belt. Do not use slings on rough surfaces. Lest the sling be cut by the edges and corners and rough surface scratch.

3. When in use, because the bending part of the hook makes the flat lifting belt cannot bear evenly in the width direction, Webbing Slings is affected by the inner diameter of the hook. The hook diameter is too small, and the ribbon loop is not sufficient, should use the correct connection.

4. Do not press items on the lifting belt, which will cause damage to the lifting belt. Do not try to pull out the lifting belt from below, Webbing Slings will cause danger. Apply the object cushion, leaving enough space for the lifting belt to come out smoothly.

The hoisting belt is strictly prohibited to tie knots. Because the lifting belt is made of a lot of polyester filament, if the knot is used, it will damage the polyester filament inside the lifting belt, or even fracture. When the polyester filament is broken, the strength and durability of the lifting belt itself will be reduced, resulting in its normal use; After the lifting belt is knotted and used, it will also cause certain strangulation marks and wear on the goods; And the lifting back after knot deformation occurs to a certain extent, which will be affected in strength and durability, and will produce certain safety hazards when used.

The most important step in the hoisting operation is to determine the weight of the object to be lifted and the center of gravity. The most accurate way to obtain the weight data of the lifted object is the data provided by the manufacturer. If accurate information is not available, then the weight must be determined by other methods, such as actual weighing or calculation.

1. In order to lift safely, it is necessary to know where the center of gravity is before operation to accurately balance the load. If the weight is lifted directly above the center of gravity, it moves most easily and does not tilt.

2, the weight of an object is evenly distributed around the center of gravity point, during the lifting period, this point should be guaranteed to be directly below the hook.

3. When the weight leaves the ground, it tilts, indicating that the line between the hook and the center of gravity is not on the vertical line through the center of gravity.

4. If the inclination is greater than 5 degrees, lower it and reconfigure it.

5. If a heavy object has a symmetric shape and stable density, the center of gravity lies at the geometric center of the object.

6. In the application of lifting, symmetric heavy objects, such as I-shaped beams, pipes and steel plates, can be lifted with a geometric center of gravity.

7. If the shape or density distribution is irregular, the center of gravity is closer to the heavy part.
