In daily life, when encountering strong light, we instinctively close our eyes or avoid it, because the human eye is highly sensitive to strong light. Similarly, during the use of lifting belts, special attention should be paid to avoiding strong light exposure, especially direct sunlight.
Sunlight is essentially blackbody radiation produced by solar nuclear reactions, which is filtered by the Earth's atmosphere before reaching the ground. In 1666, Newton confirmed through his famous dispersion experiment that sunlight is composed of a mixture of multiple colored lights, which greatly deepened human understanding of sunlight. In modern industrial operations, the use of lifting belts must strictly avoid direct sunlight, for the following reasons:
Firstly, during storage, it is essential to avoid direct sunlight exposure to the lifting straps. Sunlight is rich in ultraviolet rays, and long-term exposure to such an environment can accelerate the aging of the material of the lifting belt, causing damage to its internal fiber structure and significantly increasing the risk of breakage, posing a serious threat to the safety of lifting operations.
Secondly, direct sunlight should also be avoided during the lifting process. Regardless of the season, the glare of sunlight should not be underestimated. Under direct sunlight during lifting operations, the operator's line of sight will be severely disrupted, making it difficult to observe the lifting status of the object clearly, which can easily lead to operational errors and ultimately result in safety accidents.
The physical properties of sunlight are complex, and reasonable utilization can bring many conveniences to life. However, if used improperly, it can cause serious problems in industrial production and other fields. Effectively avoiding direct sunlight during the use and storage of lifting belts is a key measure to ensure operational safety and extend the service life of lifting belts.
