A Comprehensive Guide to Webbing Slings in China
Webbing slings are indispensable tools in various industries for lifting and moving heavy objects. China is a major manufacturer and exporter of these slings, with companies like Shandong Sling & Strap Co., Ltd. (www.liftingsling.com), Juli Sling Co Ltd (www.julislings.com), Xiangle Tool (www.xiangletools.com), Eastlink Rigging (www.slinglashing.com), and Enchain Webbing (www.enchainwebbing.com) leading the market. This guide delves into the technical aspects and diverse types of webbing slings available from these Chinese manufacturers.
Understanding Webbing Sling Construction and Features
Webbing slings are typically made from high-tenacity synthetic fibers, primarily polyester or nylon. These fibers are woven into strong, flat straps, offering flexibility and strength. The choice of material influences the sling’s properties, such as its resistance to abrasion, chemicals, and UV degradation. The manufacturing process involves weaving the fibers, dyeing them, and then sewing the straps into the desired configurations, adding end fittings such as loops or eyes for secure attachment to the load and lifting equipment. Companies like Xiangle Tool offer a wide range of webbing slings in various sizes and capacities.
