First, a sling can lift five tons of stuff, so we are naturally think of, if you lift 10 tons of things that only use two carrying 5 tons of things to die. In fact, this idea is wrong. Secondly, the safety factor lifting devices with higher than iron, we all know that the higher the coefficient, the greater the security, so some employees think that such a high safety factor, under normal circumstances will not overload, overload sling even break Shihai There are signs, but all on the premise that in a sling with intact state. In practice, the use of different levels will often wear spreader, lifting with a serious situation if possible within the scope of the rated load lifting sling can suddenly rupture Which is good, lifting belt in damaged condition will be no signs of fracture and therefore should always check promptly discarded.

Ensuring production efficiency, but also to fully guarantee the stability of product quality and reliability. They are digitized tape sewing equipment sewing equipment used, traces beautiful, pitch precision in improving sewing efficiency, but also greatly reduces the impact on the sling sewing thread tension. Synthetic fiber loading zone is known, if sling during sewing, the alignment is not good sling, to sling tensile properties will have a huge impact, Chen power after years of exploration and research test successfully developed a cross diamond cross stitching method, this method of sewing thread sewing and knitting yarn perfect combination together, plus the advantages of digital sewing machines, sewing is not only beautiful, but also makes sewing thread tension effect on sling greatly reduced.
