Four-leg chain slings

Four-leg chain slings are marked with the letters 4 STs. They consist of an upper end fitting that hangs on the crane jib, and four chains with round links and a strength rating of no less than property class 8 and 10. All legs end in lifting attachments of various types — hooks, shackles, forks, and rings. The choice of modification depends on the specific task.

Four-leg chain slings withstand exposure to aggressive environments, do not kink, and operate at temperatures from -40°C to +400°C. When the ambient temperature rises above 200°C, the sling’s load capacity decreases by 10%, and above 300°C it decreases to 75%.

Chain rigging equipment is used in hot shops at metallurgical and pipe-rolling plants, in the chemical industry, machine building, warehouses, and logistics. For handling certain types of loads, slings with chain legs are fitted with limiting hooks to adjust the working chain length, or hooks with a wider throat opening.
