You can use single-leg slings to make various types of BRIDLES. Two types are shown in figure 1-12. You can use two or more single slings for a given combination. Also, if an individual sling is not long enough for the job at hand, you can combine two of the single slings to form a longer single sling.
It is advantageous to have matched sets of slings (that is, two or more of equal length) so that when it is necessary to use more than one to hoist a load, the strain will be equal and the load will come up evenly. You should mark slings that are of equal length for ease of identification. Painting the eyes of equal-length slings the same color is one way of doing this.
In lifting heavy loads, always make a special effort to ensure that the bottoms of the sling legs are fastened to the load in a manner that will prevent damage to the load. Many pieces of equipment have eyes fastened to them during the process of manufacture to aid in lifting. With some loads, though, fastening a hook to the eye on

one end of each sling leg provides an adequate means for securing the sling to the load.
Chafing gear (protective pads) must be used when a sling is exposed to sharp edges at the comers of a load. Pieces of round wood, heavy bagging, or old rubber tires are excellent materials to use as padding.
Chain slings are frequently used in hoisting and moving heavy steel items, such as rails, pipes, wide- flange beams, and angles. They are also desirable for slinging hot loads and in handling loads with sharp edges that might cut wire rope.
Steel-length CHAIN SLINGS are available with variable type ends and lengths. Types include a 1/2-inch (12.7-mm) size sling, obtainable in either 12- or 20-foot (3.6-m or 6-m) lengths. This is a one-leg type of sling with a center swivel, equipped with a grab hookContinue Reading
