To attach the load, locate the center of gravity, position the crane hook directly above the center of gravity, and then rig the load so that it will lift level and true. Rigging shall be configured such that slings do not reeve or slip through the hook. Sling stresses and sling angles will also be unequal. For this reason, when the center of gravity is closer to one point of the sling attachment than to the other, the slings must be of unequal length.
While slight variations are usually permissible, if the crane hook is too far to one side of the center of gravity, dangerous tilting will result and should be corrected at once. To make a level lift, the crane hook or point of suspension must be directly above this point. The center of gravity of an object is a point around which the entire weight may be concentrated.
