Slings come in various types depending on the material and application: Wire Rope Slings for heavy-duty lifts, Chain Slings for rugged environments and adjustable leg lengths, Polyester Web Slings for lighter, delicate loads, and Round Slings for flexibility and even load distribution. Each type is chosen based on factors like load weight, surface sensitivity, and environmental exposure.

Each sling is rated by its Working Load Limit (WLL), which is determined by material strength, construction (single or multi-leg), and design factors. Industry standards such as ASME B30.9 and EN 1492 mandate that slings are tested under specific loads with safety factors ranging from 5:1 to 7:1 depending on the type. Slings also include tags or labels with WLL, material type, and inspection instructions to ensure safe usage.

Yes, slings can be tailored in length, capacity, number of legs, and end attachments like hooks, shackles, or master links. Coatings such as galvanization or PVC sleeves can be added for environmental protection or load surface preservation. Custom solutions are common for critical lifts in offshore rigs, turbine installations, or irregular load shapes, where standard slings may not be suitable.
