What are the uses of the sling? Can a sling be used as a leash?

The hoisting belt is a kind of lifting tool used to connect the loading and unloading of lifting goods, and is widely used in machinery manufacturing, construction and installation, petrochemical industry, national defense construction, metallurgical mining industry and ports, docks, construction sites and other lifting places. It is also commonly used to hoist precision instruments, objects with smooth and high surfaces, etc.

Regardless of factors such as comprehensive cost, the hoisting belt can be used as a traction belt for its corresponding load according to the nominal load, but the cost is not higher. If the hoisting belt that is on the verge of scrapping can be used as a traction belt, it is possible to do its best under the premise of ensuring safety.

After the hoisting belt is used as a traction belt, the hoisting belt is overloaded because it is easy to be subjected to impact load during the traction process. In my personal opinion, after the sling is used as a leash, it should be changed to a professional - to become a full-time leash until retirement. It must not be allowed to sneak back and blend into the hoisting strap post again.

It is used in the military industry and coal mines, and it is more useful for lifting and handling, and it can be used as a traction rope, and it is better to use the hook at both ends.

1. The lifting belt itself is light in weight and easy to use.

2. Do not damage the surface of the object to be lifted.

3. Stable and safe lifting.

4. High strength, tonnage can be judged according to color.

5. Improve labor efficiency and save costs.

6. Corrosion resistance and good wear resistance.

7. It has a wide range of uses, suitable for ports, docks, chemical industry, steel, machinery, installation and other lifting places.

The lifting strap is soft and does not hurt the items and protects the hands of workers. The lifting belt is lightweight, has a larger load and a long service life. The lifting belt has clear limit working force marking and color code, which effectively improves the safety performance The lifting belt does not hurt the surface of the object being lifted, has high strength, bright colors, corrosion resistance, wear resistance, good performance, and stable and safe lifting.

The lifting belt is used to lift objects such as hooks, and can be applied to lifting objects under a variety of lifting conditions, it has high strength, and can not hurt the surface of the object, both light and soft, and can be used in a variety of combinations. The outer surface of the lifting belt is fine, and it will not cause damage to vulnerable objects. Moreover, there are many hoisting methods, which can also be used to drag the objects to be lifted.

It has a sufficient supply of lifting belts, and provides a variety of imported lifting belts. It is uniquely labelled and uses international standard colors to distinguish the carrying tonnage, making it easy to identify even if the lifting belt is worn. The daily safety check of the sling is simple and intuitive, and a broken jacket indicates that the sling has been damaged, as long as the jacket is in good condition, the sling is in good condition.

The standard color is used to distinguish the bearing tonnage, which is easy to identify.

There are many types of materials for sling copying, such as: nylon, synthetic, polyester, etc.

Synthetic sling.

In particular, the synthetic fiber sling is light to carry, easy to maintain and good chemical resistance, as well as has the excellent characteristics of light weight, high strength, and not easy to damage the surface of the hoisting object, it is more and more favored by users and gradually replaces the wire rope rigging in many aspects.

Synthetic fiber slings are divided into two categories: flat slings and round slings according to types.

Flat slings are mainly made of nylon fibers (polyamide synthetic fibers), polyester fibers (polyester synthetic fibers), and polypropylene fibers (polypropylene synthetic fibers). They have their own characteristics and can be suitable for different environments, but slings of different materials should never be mixed.

The material of the round sling is mainly polyester synthetic fiber (polyester), the outer layer is made of polyester round sleeve as a protective layer, and the inner core is made of continuous 100% polyester core yarn as a lifting load. The synthetic fiber sling is a soft sling with excellent performance, made of high-quality high-strength and low-stretch polyester filament, which is a replacement product of steel wire. Internationally, it has been commonly used in industrialized countries for more than 50 years.

Its superior performance is favored by the majority of users.

Conventional slings are generally made of high-strength polyester filament and polyisophthaloyl-phenylenediamine fiber, which has multiple advantages such as high strength, wear resistance, oxidation resistance, and ultraviolet resistance, while having a soft texture and non-conductive.

Polyester fibers are many, similar to the characteristics of polyester. There is also a nylon strap.

The material we use is high-strength polyester industrial filament.

The main materials of the sling are: polyester, polypropylene, nylon, and Dyneima.

Polyester

Polyester hoisting has the remarkable characteristics of being economical, lightweight, easy to operate and easy to maintain, and has absolute superiority in the chemical fiber hoisting belt. In acidic environments or when small elongation is required, the main product used, general acids and hot bleach have little effect on it, but it is not suitable for use in the temperature range other than concentrated sulfuric acid, alkali and -40 -100, and the elongation of polycool is about 3% (untreated) under safe working force.

Polypropylene

Almost any acid and alkali have no effect on the polypropylene sling, it has a high resistance to the chemical environment, the first choice in the chemical environment, the use of temperature range -4o -8o.

Nylon

It is widely used in the production of slings, it is not affected by grease, oil, and has strong chemical resistance to strong alkalis, ethers and aldehydes, but is not suitable for use in acid, bleach and -40 -100 temperature range other than use, nylon under the safe working force, the elongation is about 6-8%, and if wet, the strength will be lost more than 10%.

Dyneema

It has excellent comprehensive properties, its density is less than 1, and its strength is currently the highest in the world, which is 15 times that of high-quality steel. The Dyneema sling is a chemical fiber that is resistant to water, moisture, and most chemicals, with high crystallinity, and will not swell or hydrolyze in fresh water, seawater, or moisture. Dyneema slings have excellent fatigue and abrasion resistance and can be used at temperatures between -150 and 70 for short periods of exposure to high temperatures without significant performance degradation.

The above are the characteristics of polyester, polypropylene, nylon, and Dyneema slings.

There are many types of materials for hanging and collapsing, including nylon, synthetic stupid high fiber, polyester fiber and so on.

Synthetic fiber sling, especially the Hesun file round fiber sling sling, is lightweight, easy to maintain and good chemical resistance, and has the excellent characteristics of light weight, high strength, and not easy to damage the surface of the hoisting object, synthetic fiber slings are divided into two categories: flat slings and round slings, and flat slings are mainly made of nylon fibers, polyester fibers and polypropylene fibers.

The material of the round lifting belt is mainly polyester synthetic fiber, the outer layer is made of polyester round sleeve as a protective layer, and the inner core is made of continuous polyester core yarn as a lifting load.

1 ton of purple, 2 tons of green, 3 tons of yellow, 4 tons of gray, 5 tons of red, 6 tons of brown, 8 tons of blue, 10 tons and 12 tons are all orange.

Generally, it is made of high-strength polyester filament, which has multiple advantages such as high strength, resistance to cherry blossom wear, anti-oxidation, anti-ultraviolet rays, etc., and has a soft texture, non-conductive, non-corrosive (no harm to the human body), and is widely used in various fields.

There is one color of sling that is not mentioned above, and that is the white sling. This is because the raw materials of the white sling and the colored sling are different, so the tonnage cannot be distinguished by color. The use of hoisting belt is related to the success and failure of a single hoisting job, and it is also related to the personal safety of the crane and the driver.

(1) Light weight, good flexibility, easy to bend, easy to use;

2) It does not damage the surface of the hanging object, and has strong protection;

3) The lifting flat plate is stable and the safety factor is high.

Right; (4) It has high tensile strength, bright color, and is easy to distinguish

5) insulation; 6) Long life, good corrosion resistance and wear resistance

7) Improve labor efficiency and save costs;

8) It has a wide range of uses, and is widely used in aviation, aerospace, nuclear power construction, military manufacturing, port loading and unloading, power installation, mechanical processing, chemical steel, shipbuilding, transportation and other fields.

Therefore, synthetic fiber lifting belts are increasingly used in modern, scientific and technological and international hoisting construction sites.

Our company specializes in the production of various specifications of lifting belts.

The surface damage of the sling is an important factor in the reduction of the strength of the sling, so when the surface is worn, the sling will be damaged sharply. Some fracture (not fault) of the fibers on the surface of the sling is inevitable, as long as it is not too large, it will not affect the use.

1. When using, the hoisting belt is directly hung into the center of the hook and directly hung at the hook tip position, 2. The hoisting belt is not allowed to cross and twist, knotted and twisted in use, and the correct hoisting special link should be used to link.

3. The use process must be commanded by personnel with relevant qualifications, and it is strictly forbidden to overload it.

4. When the two slings are operating, the two slings are directly hung into the double groove, and each is hung in the symmetrical stress center of the double hook; When the four slings are used, every two slings are directly hung into the double hook, pay attention to the inner sling can not overlap and squeeze each other, and the sling should be symmetrical to the hook force center.

5. When encountering goods with sharp corners and edges, sheaths, corners and other methods must be used to protect the sling belt to prolong the service life of the sling and eliminate potential safety hazards.

6. When a single hoisting belt is needed to lift the cylinder, a double-turn choke ring should be used for bundling.

It should be noted that when using the sling belt, be sure to fasten the belt faucet tightly and check it many times before use, and stop using it immediately if you find any problems. It should be noted that the various parts on the lifting belt shall not be disassembled without permission, and each small part on the lifting belt is related, if accidentally removed, the small parts are easy to lose or cannot be restored to install back. Although there are many types of slings, all slings have a principle when they are used, and the users must be trained or have professional people around them to guide them to wear them.

Because the sling is different due to the different types, the way to wear is not the same, if there is no professional learning, it is easy to lead to the wrong wearing, and the consequences caused by the use of the wrong situation should not be underestimated.
