Selecting the appropriate lifting sling based on the specific situation and conditions is paramount. Diverse working environments necessitate the employment of specific sling types. Additionally, the sling’s material dictates its variety, encompassing nylon lifting slings, polyester lifting slings, chain lifting slings, and wire rope lifting slings, each tailored to different requirements.
Nylon lifting sling
Nylon lifting slings have emerged as a preferred option owing to their remarkable versatility and enduring durability. Distinguishing themselves from alternative materials, nylon web slings exhibit an impenetrable resistance to petroleum-derived substances, such as grease and oil. Furthermore, these slings demonstrate resilience towards a range of specific chemicals, encompassing ethers, potent alkalies, and aldehydes. Nevertheless, it is imperative to acknowledge that nylon webbing is incompatible with applications involving bleaching agents or acids, as well as temperatures exceeding 194°F (90°C). Additionally, nylon possesses a stretch capacity of approximately 8-10%, thus, its utilization in scenarios where elongation is undesirable is not recommended.
Polyester lifting sling
Analogous to nylon lifting straps, polyester round slings carry specific temperature guidelines and are discouraged from use above 194°F (90°C) to ensure safety. Distinct from nylon, polyester slings exhibit approximately 3% elongation of their specified load capacity. Furthermore, polyester round slings demonstrate resilience in acidic conditions due to their fabric’s resistance to bleaching agents and common acids. Nevertheless, caution is advised when exposing polyester webbing to sulfuric acids or alkaline solutions, as direct contact should be avoided.
Chain lifting sling
Chain lifting slings are impeccably suited for arduous environments and tasks, demonstrating remarkable resilience against abrasion and cutting, thereby preserving their durability and structural integrity even in extreme temperatures soaring up to 400°F (204°C). Crafted predominantly from Grade 80 steel, these slings can also be tailored to specific requirements, incorporating Grade 100 chain, which boasts approximately 25% enhanced lifting strength while maintaining a lighter profile than conventional Grade 80 chains. This superior strength, coupled with customization options, renders chain slings highly adaptable to virtually any lifting challenge.
Wire rope slings
Wire rope slings exhibit parallels with chain slings in their exceptional durability, strength, and high-temperature tolerance. Nonetheless, wire rope surpasses chain in cost-effectiveness, rendering it a preferred option whenever budgetary constraints are a factor. The abrasion resistance and flexibility of wire rope are configurable variables, enabling the customization of chain slings to employ tailored wire rope types. Commonly, wire ropes are crafted from either the 6×19 or 6×37 rope classifications. The 6×19 class prevails due to its harmonious blend of flexibility and abrasion resistance. Conversely, the 6×37 class boasts superior flexibility but at the cost of diminished abrasion resistance.
Other factors that should be taken into account are the specific specifications, such as capacity, among others.For more information, call us today at 0086-571-87153652/87153650 or email sales@liftool.com.
