When selecting the specifications of the lifting belt, the size, weight, shape of the load to be lifted, and the lifting method to be adopted must be taken into account in the calculation of the use coefficient, the limit working force requirements, and the working environment and load type must be considered. It is necessary to select a sling that has both sufficient capacity and the appropriate length to meet the use. If multiple lifting belts are used to lift the load at the same time, the same type of lifting belts must be selected; the material of the flat lifting belt cannot be affected by the environment or load. Whether accessories or soft lifting ears are required, the end of the lifting belt must be carefully considered to match the auxiliary accessories and lifting equipment.
Features
Lightweight and soft: The weight is 25% of the same metal lifting sling. The sling is very easy to control, carry and store. If there is a large cut on the round lifting belt sleeve, it must be inspected and cannot be repaired or used again.
About the characteristics and uses of the lifting belt
Lifting belts are increasingly used in modern, technological and international lifting construction sites. The products are widely used in lifting in steel mills, oil fields, ports, electromechanical, transportation and other industries.
(1) Lightweight, flexible, easy to bend, easy to use;
(2) Does not damage the surface of the object being hoisted, strong maintenance;
(3) Stable lifting, high safety factor;
(4) Has high tensile strength, beautiful color, easy to distinguish;
(5) Is an insulator;
(6) The lifting belt has a long life, good corrosion resistance and wear resistance;
(7) Improves labor efficiency and saves costs;
(8) Widely used, widely used in aviation, aerospace, nuclear power construction, military manufacturing, port loading and unloading, power equipment, machinery processing, chemical steel, shipbuilding, transportation and other fields.
Differentiation
Generally, its width is 15 mm, 30 mm, 50 mm, 60 mm, lifting belt other, flat lifting belt: industrial strong silk warp woven into dyed industrial webbing. Lifting belt, 75mm, 90mm, 100mm, 120mm, 150mm, 180mm, 240mm, 300mm, the width of the lug is 30mm, 50mm, 60mm, 70mm, 80mm, 100mm.
Industrial webbing is sewn into flat lifting belt by industry. In any case, if the user is not sure of the degree of damage, it is best to send the round lifting belt back to the manufacturer for further inspection. The flat ring lifting belt is just a ring. When the load-bearing core is partially damaged due to overload or temporary use, its jacket will first break to warn and avoid accidents.
Synthetic fiber lifting belt is a soft sling with excellent performance. It is made of high-quality high-strength and low-stretch polyester filament and is a replacement product for steel wire rope. It has been widely used in industrially developed countries internationally for more than 50 years. It does not damage the surface of the hanging parts (including the paint layer) and does not cause any negative harm to the human body.
Generally, lifting belts are difficult to corrode and are non-conductive. TA type lifting belt is a ring-shaped sling with a wear-resistant outer cover and a high-strength rope core inside (also known as "universal sling", one of the most widely used soft slings). Round lifting belts are composed of infinitely encircled equally arranged tows to form a closed load-bearing core, and are twisted with single strands of wire. The number of wires in a row reaches more than 100,000 cycles, which plays a load-bearing role. Synthetic fiber lifting belts are soft and easy to control.
Performance and advantages
Performance:
Strength: Flat lifting belt 1T-30T Round lifting belt 1T-300T
