The first step: braided lifting straps The tape is woven from fabric without any obvious defects, and all threads should be made of the same material during the weaving process. Standard widths are 25mm, 35mm, 50mm, 75mm, 100mm, 150mm, 200mm, 300mm. Step 2: Pay attention to deviations Allowable deviation of bandwidth, when the bandwidth is 100mm, the allowable deviation is 10%; when the bandwidth is greater than 100mm, the allowable deviation is 8%. The thickness of the belt should be uniform. When the lifting belt is composed of multiple belts, the thickness of each belt is the same. Step 3: Sewing the sling
