Use and safety precautions of slings and rigging; overview; general safety regulations for slings and riggings Lifting items mainly include: hooks, end hooks, and slings; rated lifting weight of the sling: when the sling is vertically suspended under normal use conditions; the composition of the rigging: generally composed of high-strength flexible parts (wire rope, Lifting chain; the ultimate working load of the sling: refers to the sagging of a single sling under normal conditions of use; the maximum safe working load of the sling: In addition to the vertical suspension, the use of slings and safety precautions are summarized. General safety regulations for rigging, types and specifications of commonly used rigging, slings: rigid fetching devices for hoisting and hoisting operations can lift objects directly, mainly including: hooks, end hooks, rings, shackles, Special slings, etc. Rated lifting capacity: Under normal conditions of use, the sling is allowed to bear the maximum mass (weight) of the item when it is hung vertically. The retrieval device is called a rigging or sling. The composition of the rigging: generally composed of high-strength flexible parts (wire rope, lifting chain, artificial fiber belt, etc.) with end loops, hooks, shackles, etc. The ultimate working load of the sling: refers to the maximum mass (weight) of the sling that is allowed to bear the maximum mass (weight) of a single sling when it is vertically suspended under normal conditions of use. There is an included angle between the slings, which makes the force of the sling change, and the maximum mass allowed under a specific hanging method. It is called the maximum safe working load of the sling. General safety regulations for slings and riggings The purchase of the tool must be produced and inspected by a professional manufacturer in accordance with national standards, with a certificate of conformity and maintenance and maintenance instructions. The rated lifting weight, production number, manufacturing date, and factory name are marked on the obvious place of the product. Self-made spreaders For self-made or modified slings with a rated lifting capacity of more than 500kg, the design drawings, calculation books and other technical data should be submitted to the production and operation department for approval. The minimum distance between the weaving and inserting parts of the buckle shall not be less than 10 times the diameter of the wire rope. The weaving and inserting operation shall be pierced at least five times for each strand, and at least three of the five times shall be interspersed with the whole strand. The purchased slings and riggings should be tested according to the specified test load and test method before they can be put into use. Common types and specifications of rigging slings are indispensable tools for binding and fixing items in the process of lifting and hoisting.
