In recent years, China's sling industry has developed rapidly, the market variety is also varied, how to choose the sling has become a headache for customers, the following is for you to introduce how to choose the right sling.
First: from the concept to select the sling
The rope is made of steel wire rope as raw material, mainly used for hoisting, traction, tensioning and carrying the rope, the specific strength of high, light weight, smooth work, not easy to break the whole root and other characteristics, widely used in steel, Transportation, port and other industries.
Chain rigging is a metal chain connected to the rigging, in accordance with its formation are mainly welded and assembled two, according to its structure is a single and more than the use of high-quality alloy steel, its prominent feature is wear, high temperature , The ductility is low, the force will not be elongated. Its long life, easy to bend, suitable for large-scale, frequent use of the occasion. Flexible multi-limb, a variety of combinations can improve work efficiency, reduce costs and so on.
Lifting with a set of rigging from the main ring, link shackles, lifting belt, metal terminal components, the main ring, including long rings, round rings, combined rings and so on. The shackles include the bow shackles, the chain shackles, etc. The lifting belts include flat belts and round belts. The metal ends include all kinds of hooks and other metal parts. The sling rigs can be freely optimized according to the customer's needs.
Second: from the use of precautions to select the sling
Wire rope rigging Note:
1, if the single-legged lifting belt, hanging point must be located vertically in the hanging material is above the center of gravity;
2, if the legs hoisting, hanging points should be located on both sides of the goods, hanging in the hanging material at the top of the center of gravity;
3, if the three legs or four legs hoisting, hanging point must be symmetrical on the plane around the goods, and the hook is located in the hanging material is just above the center of gravity.
Lifting with a rigging Note:
1, in the use of the process should pay attention to the relationship between the angle and bearing tonnage;
2, if the set of rigging used in the lifting belt with damage, you can not use;
3, to avoid the impact or vibration of the load;
4, the safety factor of 4: 1, a specific 5: 1 or 6: 1, to be used within the safety factor range.
Chain rigging Note:
1, the chain is not allowed in the course of knotting or twisting;
2, can not use the hook tip load;
3, the chain rigging normal operating temperature -40 degrees to +200 degrees;
4, one leg rigging, lifting point should be located vertically above the center of gravity of the object;
5, if it is a leg rigging, hanging point should be located on both sides of lifting objects, lifting point in the center of gravity above;
6, if it is three legs and four legs with rigging, hanging point should be evenly located in the lifting point of the object center of gravity, and was hanging material center of gravity above.
We need to remind everyone, when the choice of sling, the lifting of the load must be the size, weight, shape, and ready to use the lifting method are should be taken in the consideration, while the sling with the ultimate working force requirements, working environment, The type of load also need to be considered!
