Table – Working Load Limits (WLL) for Chain Chain Size in millimeters (inches) Unmarked Chain Grade 30 proof coil Grade 43 high test Grade 70 transport Grade 80 alloy Grade 100 alloy …

Jan 19, 2025 · A chain’s working load limit (WLL) represents the maximum weight a chain can safely handle during operation. You calculate it by dividing the chain’s minimum breaking …

Use this table as a guide to Peerless chain sling working load limit (WLL) specifications. You can also use this table to determine which chain size and leg styles are best for your requirements. …

(1) The horizontal angle is the angle formed between the inclined leg and the horizontal plane [see figure 1(d)]. (2) Rated loads are for angles of choke greater than 120 degrees. Table 4

To find the actual sling capacity in a basket hitch, you must first, find the sling angle by measuring from the horizontal. Once the angle is determined, (using the 90° basket hitch capacity), …

Sep 21, 2020 · Determine if the correct lifting method for the load requires a single leg, multiple leg or an endless sling configuration. Consult the WLL table to determine which size chain will …

It is imperative to never exceed the chain sling's working load limit (WLL). This limit is calculated according to the sling's grade, size, and angle of use. The diagrams below outline the WLL of …

WLL (ton) = 4 x WLL for single leg sling x cos β. β = the legs angle against the vertical surface. In case of a multi-leg sling, the maximum load of the master link must be at least equal to that of …

Watch the load and be prepared to stop applying force if the load starts buckling. Buckling may occur if the load is not stiff enough to resist the compressive forces which result from the …

May 24, 2023 · In a basket hitch configuration, the angles between the sling legs and the horizontal plane affect the load distribution and WLL. Larger angles can result in increased …
