Hoisting of wire rope rigging: if it is a single leg hoisting belt, the hanging point must be located directly above the center of gravity of the suspended object.
If the legs are hoisted, the hanging points should be on both sides of the goods and the hooks are above the center of gravity of the suspended objects.
If it is hoisted for three legs or four legs, the hoisting point must be well proportioned in the plane around the goods, and the hook is located right above the center of gravity of the suspended material, and the lifting belt is hoisted to the attention: in the course of use, pay attention to the relationship between the angle and the bearing tonnage. If the lifting belt used in the set of rigging is broken, it can not be used. A shock or vibratory load.
The safety factor 4:1 is 5:1 or 6:1, which is used in the safety factor range.
Chain rigging is sling attention: the chain is not allowed to knot or twist during the use, and can not be loaded with the tip of the hook. The chain rigging has a normal working temperature of -40 degrees to +200 degrees, a single leg rigging, and the lifting point should be perpendicular to the center of gravity of the lifting object; 5, 3 if it is a double leg rigging, the hoisting point should be both sides of the lifting object. The lifting point is above the center of gravity. If it is the three leg and the four leg rigging, the hoisting point should be evenly located on the center of gravity of the lifting object, and above the center of gravity of the lifting object.
