Restrictions and techniques for the use of slings

Limitations on the use of slings-Angle: When using soft lifting lugs, flat slings, etc., the maximum thickness of the lifting part of the hook should not be greater than 3.5 times the length of the lug. In addition, the angle of rotation should not exceed 20° during activities. When using and lifting slings with soft ears, the slings and the links and contact parts of the slings must be consistent, unless the selected sling has an axial width less than 75mm. When lifting, the radius of the crane and its selected accessories must be more than twice the axial width of the sling, so as to ensure the safety of construction.

　　 Tips for using slings: When choosing slings, first consider the selected specifications. Because in different situations, the shape, weight, size and even environment of the hoisting are different. This requires the construction party to select products of appropriate specifications to meet the operations in different occasions. If it is the same lifting operation, products of the same specification should be selected and matched to jointly lift the sling.

Finally, when choosing slings such as hooks and rings, and flat slings, the raw materials and production techniques of the product should also be considered, and factors such as the construction environment and the surface treatment of the product should also be included in the category of safety. . Other lifting accessories should also consider the end of the product and whether the lifting equipment matches.
