D-ring tightener background technology tightener is a device that tightens the packing belt used in the process of goods packaging. The traditional tightener packing belt is fixed at both ends of the tightener, which makes the tightener itself too complex, and the packing belt is only fixed by a simple buckle, which is extremely easy to deposit and fall off, affecting the packaging efficiency. D-ring tightener has developed a kind of tightener that can lock, fix and cut the packing belt at one end, which makes the structure of the packer more concise and convenient for carrying, and adopts a unique design of packing belt clamping groove to effectively prevent the packing belt from detaching during the tightening process.

Sex sling is generally used in various hoisting industries. Different materials of flexible sling and D-ring tensioner have different use environments. We can choose flexible sling according to our own use environment. 1. Flexible sling has the function of durable inorganic acid, but it is easy to be hurt by organic acid. 2. Polypropylene fiber is suitable for use in places that can resist chemicals. 3. Nylon is suitable for use in places that can resist chemicals. 4. Polypropylene fiber has the ability of resisting inorganic acid, and it is easy to be hurt by organic acid. 5. When nylon is damp, its strength loss can reach 15%. 6. If flexible sling is likely to be affected by chemicals The product pollution or the service life under high temperature will also be reduced. 7. Do not use the worn flexible lifting belt. 8. When lifting, do not twist the fixed D-ring tensioner to use or knot it. 9. Choose a suitable flexible lifting belt to use and do not overload it. 10. Check each flexible lifting belt before use
