Six Things About Wire Rope Rigging

1.What is Wire Rope Rigging Wire rope rigging is a type of rope made from wire ropes that are processed and mainly used for lifting, towing, tensioning, and bearing. Wire rope rigging is characterized by high strength, light weight, stable operation, and resistance to sudden breakage, serving as a flexible connection tool between lifting and hoisting equipment and the load being lifted. From a production perspective, it is an extension or further processed product of metal products—wire ropes.

2.Practical Applications of Wire Rope Rigging In practical applications, wire rope rigging is widely used in various industries such as ports, marine and land transportation, mining, metallurgy, forestry, petrochemicals, shipbuilding, railway bridges, power construction, aerospace, and more. Particularly in lifting and hoisting operations, more than half of the wire ropes need to be processed into rigging before use.

3.Standards and Specifications of Wire Rope Rigging According to statistics, the annual processing volume of wire rope rigging in China is over 120,000 to 150,000 tons. However, despite such a large quantity of rigging products, China has not yet fully implemented serialized and specialized production, and the standard system for rigging is still incomplete. For decades, Jianfeng Rigging has been engaged in the design, production, and  sales of wire rope rigging, possessing specialized and standardized knowledge and skills in 1rigging production, giving users sufficient confidence.

4.Classification of Common Wire Rope Rigging Wire rope rigging can be classified based on processing methods into: pressed wire rope rigging, spliced wire rope rigging, seamless wire rope slings, and cast wire rope rigging.    1.Pressed Wire Rope Rigging

   Pressed rigging is one of the commonly used wire rope rigging types, generally divided into those with and without thimbles. Compared with old-fashioned wire rope rigging, pressed rigging features updated structure, more advanced technology, higher production efficiency, strong safety and reliability, large load capacity, and strong jointing of pressed connections. The surface of the joint is smooth, without cracks, burrs, or edges, making it suitable for various professional production scenarios.   2.Spliced Wire Rope Rigging

  Spliced wire rope rigging involves processing wire ropes into circular loops by splicing one or both ends of the wire rope. Compared with pressed wire rope rigging, spliced wire rope rigging is more cumbersome to operate, relatively backward in technology, consumes more wire rope per unit, resulting in higher costs. Moreover, the jointing strength of spliced rigging is weaker than pressed rigging. Therefore, it is usually used in specific applications such as the iron and steel and chemical industries.   3.Seamless Wire Rope Slings

  Seamless rigging is characterized by good flexibility, multiple lifting points, high strength, and small lifting space requirements, especially suitable for lifting large objects in environments with limited space or for large-scale lifting projects such as transformers, shipbuilding, and special machinery manufacturing.   4.Cast Wire Rope Rigging

  The manufacturing process of cast rigging is complex, requiring trained operators for casting, and it takes a certain amount of time to manufacture, resulting in low efficiency and high cost. However, the jointing strength of cast rigging is very high, mostly used in important occasions, with more on-site casting installations. Each batch must undergo tension tests before leaving the factory.

5.Usage Regulations of Wire Rope Rigging During use, what should be noted about wire rope rigging?

   1.Wire rope rigging without markings and inspection certificates is strictly prohibited from being used.

   2.Routine inspections should be conducted before use. Wire ropes or metal fittings that are damaged to a certain extent should not be used.

   3.Overloading is strictly prohibited.

   4.The included angle between the legs of the wire rope rigging should not exceed 120 degrees.

   5.For wire rope rigging with metal fittings such as hooks, rings, and chains, they should be connected with quick links, and their rated loads should be equal.

   6.Wire rope rigging lifting should be stable and avoid the impact of loads.        

   7.Effective measures should be taken to prevent wire ropes from bending at sharp angles or colliding with loads.    

   8.Dragging or throwing wire rope rigging from a height is prohibited.    9.It should not be used outside the temperature range of -40°C to 100°C.

   10.It should not be exposed to or used in corrosive gases, liquids, or vapors.

   11.For wire rope rigging stored for more than 2 years, sampling tension tests must be conducted as required before they can be put into use.

6.Inspection Rules and Periods of Wire Rope Rigging Wire rope rigging inevitably undergoes different degrees of wear and tear during use, making routine inspections indispensable.

    1.Inspection Rules     Pay attention to whether there are broken wires in the wire rope, check the degree of wear, corrosion, and oiling status, as well as whether the wire rope shows deformation, twisting, flattening, damage, etc. At the eye connection, pay attention to the fastening condition, whether there is wire rope slippage, and whether the thimble shows deformation, wear, corrosion, and cracks.

    2.Inspection Periods     Designate specialized technicians to conduct regular inspections of wire rope rigging once a month, and for wire rope rigging used frequently, shorten the inspection period according to the frequency of use.     Jianfeng Rigging has been providing the most perfect lifting solutions for every lifting and hoisting project, producing reliable wire rope rigging, always prioritizing safety, and striving to give customers a reassuring and perfect experience in rigging safety and operational training.
