  Weather conditions are often neglected in lifting operations. While most operators focus on the Working Load Limit (WLL) of a sling, environmental factors—particularly rain and moisture—can significantly impact its safe use. So, does rain actually weaken a lifting sling? Or does it introduce different risks altogether? This article explains  how wet conditions affect lifting slings , using clear examples and practical guidance for safe operations. Do Wet Slings Lose Load Capacity? Rainwater  does not reduce the rated working load limit (WLL)  of a lifting sling. A  1-ton sling remains rated at 1 ton , provided the sling is structurally sound and undamaged. However, moisture conditions introduce a range of other serious risks, which can indirectly and significantly compromise the safe load-bearing capacity of a sling. Therefore, it is essential to reduce its safe working load. Key Risks Introduced by a Moisture Environment Increased Weight (For Synthetic Slings...

  Incorrect calculation of sling load is one of the most common causes of lifting accidents. Many people assume that the force on a lifting sling is simply equal to the weight of the object being lifted—but in reality, the tension acting on a sling is often far greater than the weight of the load itself. This article breaks down how sling load is calculated, what factors affect sling tension, and how to avoid the most common mistakes in actual lifting operations. 1. What Is A Lifting Sling Load? Lifting sling load  refers to the actual force applied to each sling leg during a lifting operation. Key point to remember:  Sling load ≠ Load weight The load acting on a sling depends on: Lifting angle Number of sling legs Center of gravity Hitch type (vertical, choker, basket) Ignoring these factors can result in sling overload—even when the load weight is within the rated capacity. Impact of Sling Configuration on Load Distribution Different sling configurations significantly a...

  In lifting operations, choosing the right sling is just as crucial as selecting the proper crane, shackle, or hook. Among synthetic lifting slings,   round slings  and   flat webbing slings   are the two most common types used on construction sites, in factories, warehouses, and equipment installation projects. Both are made of high-strength polyester fibers, offering light weight, flexibility, and ease of handling. They also comply with international standards such as EN 1492, AS 1353/AS 4497, and WSTDA specifications. However, they differ significantly in structure, performance, ideal applications, durability, and safety characteristics. This article provides a comprehensive comparison of round slings versus flat webbing slings, helping you understand their differences and choose the right sling for your specific lifting needs. Round Sling VS. Flat Webbing Sling The most important and fundamental difference between these two sling types is their  load-b...

  Round slings  are a go-to choice for lifting and moving heavy loads, prized for their strength, flexibility, and safety. But with various options available, selecting and using the right one is key. This guide covers everything you need to know: from understanding different sling types and picking the right one, to crucial safety tips and maintenance advice. What is a Round Sling? A round sling is a type of lifting sling made from high-strength synthetic fibers. Compared to other slings like flat webbing slings or chain slings, round slings offer superior flexibility and conformability. They are uniquely designed to cradle and evenly distribute the load’s weight, making them an ideal choice for lifting objects that are irregularly shaped, have delicate surfaces, or are easily damaged. Two Key Components Core:  The internal load-bearing element, made of parallel, high-strength synthetic yarns that provide the sling’s lifting strength. Protective Sleeve:  A durable w...
