With the needs of industrial development, awareness of the increasing level of product quality, widely used synthetic fiber loading zone has been noted widely in the machinery manufacturing industry, especially in heavy machinery, large-scale power generation equipment and nuclear engineering industry, China's Guan with spreader still use the rope, it is not only large sling stiff, inflexible, while Yi Le hurt the workpiece, affecting the quality of products. To prevent injury Le phenomenon, although the use of a number of measures, such as copper or felt pad, plus soft cover, etc., it will not only cause a waste, more importantly, can not overcome a fundamental piece Le injury and so on. According to incomplete statistics, in the amount of Le workpiece lifting the injury caused by the lifting rope thanks to the annual accounts for around 30% of the workpiece, especially large tonnage, the greater the proportion of high-precision workpieces. Its rework and scrap costs are staggering. Industrialized countries for large tonnage, high-precision parts, lifting its provisions have been made, are not allowed to use the rope, and the use of synthetic fiber loading zone. The use rate has reached 7. % The above. To sum up: We are, according to the domestic polyester filament developed for industrial needs 20 tons of series sling. This sling is made up of several bundles as the bearer of the inner core of polyester filament surrounded by such external surround tow using a special process set eleven protective cover, protective cover is woven sling material, the surface with Tonnage marking and labeling. This structure is called foreign "Tile suspenders" My call "core wear suspenders." Because of this structure with longitudinal fibers tow loads in parallel. Loaded core non-woven structure. By the time the tow load can be adjusted between each other, so that even by force, in the best stress state. Elongation also in the smallest state. Just to meet the needs of high strength and low stretch. Hoisting with many advantages, compared with the same metal sling is its 25%, the harness is very easy to operate, handling and storage. When lifting operation can reduce damage to sensitive operating surface and damage to the paint, the human body without any harm to reverse. Shock absorption during use, non-corrosive, non-aging, non-conductive, non-sparking in explosive environments and so on. Elongation at rated load 1.6%, close to the rope tensile properties. Lifting belt usage at a glance, intuitive and simple routine security check where the sling, and can think looks good sling is intact. Here is our answer finishing: Material: Polyester, polypropylene, nylon, Dubang Si, nylon, synthetic fiber types: single, double, four manufacturing materials: 100% polyester Strength: flat sling 1T-30T round type sling 1T-300T Bandwidth: 25mm-150mm deep elasticity: the rated load <10% of the ultimate work force of 2% -3% load identification: In use, after the label on the harness straps worn by the color of the jacket tube identification bearing quality. Working temperature: -40-100 ° C Safety factor: 5: 16: 17: 1 new industry standard JB / T8521.1-2007 production sling, product safety factor of six sling brand _ chen flat sling ( Certified) _ sling from Hebei chen sling Manufacturing Limited.
