Used in flammable and explosive environments

Conventional lifting belts (synthetic fiber lifting belts) are generally made of high-strength polyester filament, which has multiple advantages such as high strength, wear resistance, oxidation resistance, and UV resistance. At the same time, their texture is soft, non-conductive, and non corrosive (without any harm to the human body), and they are widely used in various fields. There are many types of lifting belts. Conventional lifting belts (according to their appearance) are divided into four categories: annular core piercing, annular flat, double core piercing, and double flat.

Lifting straps are generally used in flammable and explosive environments and do not generate sparks themselves. Since its successful application in the industrial lifting field in the United States in 1955, the world's first synthetic fiber flat lifting belt has been widely used in shipbuilding, metallurgy, machinery, mining, petroleum, chemical industry, ports, power, electronics, transportation, military and other fields. The lifting belt has the advantages of portability, easy maintenance, good chemical resistance, as well as excellent characteristics such as light weight, high strength, and not easy to damage the surface of the lifted object. It is increasingly favored by users and gradually replaces steel wire rope rigging in many aspects.

The main disadvantage of lifting belts is that they are different from steel wire ropes. When the lifting object has sharp edges, these sharp edges can cause destructive cuts to the lifting belt. To protect the lifting belt from cuts, a protective lining can be placed between the lifting belt and the lifted object.

Lightweight and Soft: Weighing 25% of an equal metal sling, this sling is very easy to handle, handle, and store. If there is a large cut on the sleeve of the circular lifting belt, it must be inspected and cannot be repaired or continued to be used.

Analysis of the characteristics and uses of lifting belts

Lifting belts are increasingly being used in modern, technological, and international lifting construction sites. The product is widely used in lifting industries such as steel mills, oil fields, ports, electromechanical, and transportation.

(1) Lightweight, flexible, easy to bend, and easy to use;

(2) Not damaging the appearance of the suspended object, with strong maintainability;

(3) Safe and stable lifting with high safety factor;

(4) Has high tensile strength, beautiful colors, and is easy to distinguish;

(5) It is an insulator;

(6) The lifting belt has a long service life, good corrosion resistance, and wear resistance;

(7) Progress, rest, obey, and save costs;

(8) It is widely used in various fields such as aviation, aerospace, nuclear power construction, military manufacturing, port loading and unloading, power equipment, machine processing, chemical steel, shipbuilding, transportation, etc.

Generally, its width is 15mm, 30mm, 50mm, 60mm, with other lifting straps. Flat lifting straps: industrial strong silk is woven and dyed into industrial woven straps. Lifting straps, 75mm, 90mm, 100mm, 120mm, 150mm, 180mm, 240mm, 300mm, with lifting ear widths of 30mm, 50mm, 60mm, 70mm, 80mm, and 100mm.

Industrial woven belts are sewn into flat lifting belts by industrial sewing. In any case, if the user cannot determine the level of damage, it is best to send the circular lifting belt back to the manufacturer for further inspection. And the flat annular lifting belt is just a circular ring. When overloading or temporary use causes local damage to the bearing core, the outer jacket will first break as a warning to avoid accidents.

Synthetic fiber lifting belt is a high-performance soft sling made of high-quality high-strength low elongation polyester filament, which is a replacement product of steel wire rope. Internationally, it has been widely used in industrialized countries for over fifty years. No damage to the surface of the suspension (including the paint layer) and no negative harm to the human body.

Generally, lifting straps are difficult to corrode and non-conductive. TA type lifting belt is a woven wear-resistant outer jacket, which is a circular sling made of high-strength rope core inside (also known as "universal sling", one of the most widely used soft slings). The circular lifting belt is composed of a closed load-bearing core consisting of endless and equally arranged wire bundles. The Tianjin lifting belt is twisted with a single strand of wire, and the number of threads in a row reaches more than 100000 cycles, playing a load-bearing role. Synthetic fiber lifting straps are soft and easy to handle.

Selection of specifications and types

Broadcast

edit

When selecting the specifications of the lifting belt, the size, weight, shape of the load to be lifted, as well as the coefficient of the intended lifting method and other factors that jointly affect its usage, must be included in the calculation. The requirements for the given ultimate working force must also be taken into account, as well as the working environment and type of load. It is necessary to choose a suitable length of lifting equipment that has sufficient capacity and can meet the usage requirements. If multiple lifting belts are used to lift loads simultaneously, the same type of lifting belt must be selected; The raw materials of flat lifting belts should not be affected by the environment or load. Regardless of whether accessories or soft lifting ears are required, careful consideration must be given to matching the end of the lifting belt with auxiliary accessories and lifting equipment.

matters needing attention

edit

Follow good lifting experience and plan lifting and lightweight operation plans before starting lifting. When lifting, the correct method of using lifting straps is to properly place and connect the load in a safe manner. The lifting straps must be placed on the load so that the load can balance the width of the sling; Always do not tie or twist the seam of the sling. Do not place it on the hook or lifting equipment, and always place it on the upright part of the sling. Prevent damage to the label by keeping it away from the load, hook, and locking angle.

Usage precautions

1. Do not use damaged lifting straps;

2. During lifting, do not twist or twist the lifting straps;

3. Do not let the straps tie when using;

4. Avoid tearing open sewing joints or overloading work;

5. When moving the sling, do not drag the sling;

6. Avoid forceful grabbing or shaking to cause load on the sling;

7. Each sling must be carefully inspected before use;

8. Taylon has the ability to withstand inorganic acids, but is susceptible to damage from organic acids;

9. Fiberglass is suitable for places that are most resistant to chemicals;

10. Nylon has the ability to withstand strong organic acids and is susceptible to damage from surface acids. When exposed to moisture, its strength loss can reach up to 15%;

11. If the sling is contaminated with chemicals or used at high temperatures, the supplier should be consulted for advice.

Usage requirements

When using a flat sling with soft lifting ears, the minimum length of the lifting ear used should not be less than 3.5 times the maximum thickness of the hook in contact with the lifting ear, and the angle of movement of the lifting ear should not exceed 20 °. When connecting slings and lifting equipment with soft lifting ears, the contact part between the slings and lifting equipment must be continuous, unless the axial width of the slings does not exceed 75mm, and the bending radius of the lifting accessories must be at least 0.75 times the axial width of the slings.
