The sling manufacturing and use tie down hooks industry is a conservative industry, which may not be a bad thing. Change is slow and needs to be considered. We ask all users and manufacturers of slings to provide three best practices. For overhead hoisting, please choose the correct sling, unless you know how to use the sling, the mode factors to be applied, etc., do not try to hoist. "Her second point is to check the sling before use. "Do not use defective slings or accessories. The third point is: "Never let anyone stand under or ride on the suspended cargo. "Clear, wise and timeless advice. The current major change in sling technology and practice is the use of markings, which in particular helps greatly simplify the second recommendation of H-Lift’s above recommendations, which is not to use defective slings. Or accessories. When we asked H-Lift about its latest product improvements, they chose this product: “RFID tags are increasingly used in slings,” Ni said. “Embedded in metal or high-density synthetic carriers, RFID will not be crushed during normal use and allows customers to mark slings that are exposed to harsh environmental conditions (including extreme temperatures and environments exposed to oil, chemicals, water, dust and other pollutants.

Polyester, wire rope and chain slings relate the safety of slings to the frequency of inspections. Their three recommendations are to check the slings according to their usage-the higher the frequency of the slings, the more frequent the inspections. High; also check according to the use environment-the worse the working conditions of the sling, the higher the frequency of re-checking; third, consider the service life of the sling-check the older sling frequently, and according to the previous The experience of using slings leads to conclusions. Their replacement guidelines are comprehensive. ANSI B30.9 provides standards for removing slings from service. These include the presence of acid or caustic burns; melting or charring; holes, cuts or obstacles The suture of the pressure-bearing joint is broken or frayed; any part of the sling is knotted; excessive pitting or corrosion on the accessories; and signs of ultraviolet degradation. If you find that the sling is deformed, please remove it from the service The sling; whether it has an identification label that is not readable in any way; and any time for any reason that the sling exceeds its rated capacity. In addition, their sling has a red core safety yarn, which acts as a sling The safety yarn can be seen when the outer layer is worn, which indicates that the sling should be scrapped.

To date, Safeway Sling is one of the few female-owned companies in the industry. However, in April this year, they were acquired by Bishop in Houston Acquired by Lifting. Bishop has its own recommendations to get the best performance from webbing and round slings. If the lifting sling is damaged, please do not use them until a qualified person conducts a thorough inspection and declares that they are suitable for use. Should Avoid improper or unbalanced load and overload at all costs. Pay attention to the instructions and make sure that you use the correct sling configured correctly for the current job. The bishop also pointed out that most synthetic sling accidents are caused by sharp, unnoticed Objects are caused by cutting the material of the sling. In particular, they identify the 90-degree edge of the I-beam as a specific point where the sling that goes around them may be damaged. They provide CornerMax wear pads as a solution. They say, The pad keeps the sling away from the load angle, thus preventing the corner and the sling from contacting-in fact, the edge does not even touch the wear pad.

The two adjacent faces against the load are held in place by pressure However, avoid the corner itself. Sharp edges should also be avoided. IMCA has established rules and guidelines to reduce the strength under different d/D ratios for heavier loads in the marine environment, but not for lighter loads The load and land. The test capacity range covers the combination of round sling and shackle. The most common load increment is from 0.5t to 150t. They tested slings made of classic polyester fiber and Slings made of modern high-performance fibers. Van der Zalm said that this is of particular concern because the properties of high-performance fiber materials are different from those of conventional polyester fibers. It was found that the latter is easily affected by the separation of individual components from each other, and because The pressure at the contact point at the radius of the shackle causes damage. This is not observed in modern fibers. Van The Beest website provides the complete test results. Therefore, each link is called a Mobius strip by mathematicians. The advantage is that this arrangement is used to equalize the strain in each of the eight layers of safety belts. If the ends are connected in a conventional manner, the innermost mesh layer will be shorter than the outermost mesh layer and will bear more or less load.
