When it comes to engineering lifting belts, most of them are flexible lifting belts. Usually, large tonnage lifting belts are flexible lifting belts, and the maximum can be about 200 tons. Although the flat lifting belt is more reliable in the same specification, it is a pity that the flat lifting belt can only achieve 50 tons is the limit, then what is the reason for this?
The difference between the upper limit of the flexible lifting belt and the flat lifting belt is mainly determined by their different structures. If the flat lifting belt wants to carry more weight, it needs to double its width. When the width of the flat lifting belt is too large, the connection becomes a problem.
And flexible lifting belt can be load 200 tons, because it is in the process of production need to increase the diameter, because the flexible lifting belt cross section assumes the circular, also called circular lifting belt, while the multiple of diameter growth than flat lifting belt width is much smaller growth, so the production of flexible lifting belt space utilization rate is not high, to the normal lifting operations.
This is the main reason why the rated upper limit of flat lifting belt is not as high as flexible lifting belt.
