Single and Multiple Leg Chain Sling for Industrial Applications techsite.io/p/1322320
Introduction The industrial and construction units have large applications of a chain sling. They are highly useful for lifting and carrying heavy loads within a specific distance with ease and comfort. Slings have upper end fitting for attaching to a beam along which the sling travels. The lower end fitting is for carrying the load. Coupling links connect the two ends through a long chain. Distance between the upper and lower ends is called the reach of the chain.
Single Leg Sling – Construction and Working Single leg chain sling can carry one load at a time from one location to the other using manual operation. The hooks can be self-locking or manual locking types. It is possible to carry heavy loads, especially the molds and machinery in the manufacturing and injection moulding industries. The master hook can be attached to a beam or other platform for moving along its length. Fatigue resistance is one of the key characteristics that you need to check while inspecting the sling for quality. Fatigue can reduce the lifespan of the chain and the hooks considerably. Hence, the choice of material should be given importance. Galvanized steel can have maximum fatigue resistance with protection from rusting and corrosion. The chain should be flexible and rotatable in 360-degrees for placing the load of any location of your choice. Abrasion strength is the other feature you should consider while choosing the sling.
Multiple Leg Sling – Extended Lifting Capacity A common lifting link connects the multiple branches of chain sling to ease the task of carrying more than one load. The length of every chain has to be preferably the same for transporting the loads without damaging its structural integrity. Multiple chain sling can be two, three, or four in numbers, depending on the type and volume of load being carried. Combination of chains and webbing ratio has to be analyzed well before choosing the chain type. The ratio depends on the size of the load being carried. For example, you can consider a ratio of 6:1 for the injection moulds. The sling efficiency will be 80%. Similarly, 1:1 chain will have an efficiency of 50%, while the 20:1 chain will have an efficiency of 90%.
