Pictures Illustrated: Suggested Tips for Using Synthetic lifting slings Safely

With the development of the industry, hoisting operations are being applied more and more widely, and safety accidents in hoisting operations have received increasing attention. Using synthetic lifting slings correctly can reduce accidents, improve the safety factor, and enhance work efficiency.

How to use lifting slings correctly? WRISTRONG suggests starting from the following aspects:

1. When using more than two lifting slings for an operation, pay attention to preventing the lifting slings in the hook from overlapping or squeezing each other. The central position of the resultant force borne by each lifting sling should be consistent with the force-bearing center position of the hook.

2. When using a lifting sling, it is not allowed to tie it around the hook in a loop; and it cannot be hung on the pointed part of the hook.

3. In hoisting operations, lifting slings are not allowed to cross or twist, and it is not allowed to tie knots or twists. Special lifting sling connectors should be used for connection.

4. When hoisting goods with sharp corners or edges, methods such as using protective sleeves and corner protectors must be adopted to protect the lifting slings, so as to extend the service life of the lifting slings. It is strictly prohibited to use lifting slings on rough surfaces to prevent the lifting slings from being cut by the sharp corners or scratched by the rough surface.

5. When using a flat lifting sling, due to the curved part of the hook, the flat lifting sling cannot bear the load evenly in the width direction, which is affected by the inner diameter of the hook. When the diameter of the hook is too small, it is not fully combined with the eyelet of the webbing. The correct connector should be used for connection.

Knowledges Of Four Classifications and Characteristics of synthetic lifting slings

1. Flat lifting sling: Industrial strong filaments are woven into industrial webbing through knitting, and the widths are 15mm, 30mm, 50mm, 60mm, 75mm, 90mm, 100mm, 120mm, 150mm, 180mm, 240mm, 300mm. The widths of the lifting lugs are 30mm, 50mm, 60mm, 70mm, 80mm, 100mm. The industrial webbing is sewn into a flat lifting sling with industrial sewing. Each side of the flat eyelet lifting sling has a lifting ring, and there is an anti-wear protective sleeve sewn on the lifting ring. Several layers of webbing in the middle part of the flat eyelet lifting sling are sewn together. While the flat endless lifting sling is just a circular loop.

2. Synthetic Fiber lifting sling is a high-performance soft lifting sling, manufactured from high-quality high-strength and low-elongation polyester filaments, and it is a replacement product for steel wires. In industrially developed countries internationally, it has been commonly used for more than 50 years. Its superior performance is highly favored by users. Its main features are as follows: Light and Soft: The weight is 25% of that of the same metal lifting sling, and this lifting sling is very easy to operate, carry and store. It will not damage the surface layer of the hoisted item (including the paint layer), and has no negative harm to the human body. Safe and Reliable: It has the characteristics of shock absorption, corrosion resistance, aging resistance, non-conductivity, and no sparks in flammable and explosive environments during use. The elongation under the rated load is 1.6%, and its tensile characteristics are close to those of steel wire ropes. The usage status of the synthetic fiber lifting sling is clear at a glance, and the daily safety inspection is intuitive and simple. It can be considered that a lifting sling that looks intact is indeed intact. The synthetic fiber lifting sling is soft and easy to operate. It is not corrosive and does not conduct electricity.

3. The Round lifting sling is composed of a closed load-bearing core formed by endless and parallel arranged bundles of filaments. Single strands of filaments are twisted, and the number of strands in a row reaches more than 100,000 turns, playing a load-bearing role. Round lifting slings are all circular and have no eyelets. The outer layer of the round lifting sling is a specially made double-layer wear-resistant sleeve, which is butted into a loop. The outer sleeve does not bear the load, but only protects the parallel arranged bundles of filaments. When there is local damage to the load-bearing core due to serious overloading or long-term use, the outer sleeve will break first as a warning, which can avoid the occurrence of accidents. If there are large cuts on the sleeve of the round lifting sling, it must be inspected to determine whether it can be repaired or continue to be used. In any case, if the user cannot determine the degree of damage, it is advisable to send the round lifting sling back to the manufacturer for further inspection.

4. The TA-shaped lifting sling is an endless lifting sling (also known as a "universal lifting sling") formed by a woven wear-resistant outer sleeve with a high-strength rope core inside, and it is one of the most widely used soft lifting slings. The circular structure allows the lifting sling body to wear cyclically, and the service life of the lifting sling is longer.
