What are the inspection methods for the quality of ton bag slings and slings?
How much force can the sling on the ton bag to hold?
The ton bag is a kind of transportation packaging container, its quality is very important, and there are strict standards for its quality in the market. In the measurement of the quality of ton bags, the slings and slings are also links that cannot be ignored;
The first is sampling; intercept a sling sample of appropriate length at the lifting ring of the ton bag, and the sling sample is at least two pieces.
The second is the tensile strength test; the sample is mounted on the fixture of a tensile testing machine with a fixture spacing of 220mm, stretched at a speed of about 100mm/min, and the tensile strength at break is measured. Elongation test: install the sample on the tensile testing machine, apply a tension load of 196n, draw a marking line with a spacing of 200mm, and stretch at a speed of 100mm/min. When the load reaches 30% of the tensile strength f, Measure the spacing of the reticent.
Ton bag ton bag sling performance:
Strength: flat sling 1T-30T round sling 1T-300T
Bandwidth: 25mm-250mm
Elastic elongation: 2%-3% under rated load <10% of ultimate working force
Load identification: During use, after the label on the sling is worn, the carrying tonnage can be identified by the color of the sling jacket.
Working temperature: -40~100℃ Safety factor: 5:1 6:1 7:1
