1. Select specifications and sling types. When selecting the specifications of the sling, consideration must be given to the requirements for ultimate working force and working environment, as well as the size, weight, shape of the load to be lifted, and the coefficient of use that is jointly affected by the lifting method used., The type of load must be considered. It is necessary to choose a sling with sufficient capacity and appropriate length to meet the usage requirements. If multiple slings are used simultaneously to lift the load, the same type of sling must be used; The material of the flat sling is not affected by the environment or load. Whether accessories or soft ears are required, careful consideration must be given to matching both ends of the sling with auxiliary accessories and lifting equipment.

2.When using a flat sling with soft ears, the angle of the sling should be limited. The length of the less used sling should not be less than 3.5 times the thickness of the hook in contact with the sling, and the movement angle of the sling should not exceed 20 °. When connecting a sling to a lifting appliance with soft ears, the contact part between the sling and the lifting appliance must be straight, unless the axial width of the sling does not exceed 75mm and the bending radius of the sling is at least 0.75 times the axial width of the cable.

3. Follow good improvement experience. Plan the lifting and operation plan before starting the lifting.

4. When lifting, use the correct sling connection method. The sling is properly placed and securely connected to the load. The sling must be placed on the load so that the load can balance the width of the sling; Do not tie or twist the sling. The cable suture should not be placed on hooks or lifting equipment, but should always be placed on the vertical part of the sling to prevent damage to the label due to being away from the load, hook, and lock angle.
