一、链环的部分技术参数起重链环现货产品较多,用户在选用时须注意其制作质量。如每节起重链环上一般均有生产厂商的编号,起重链环的内宽公差极小,有些链环表面涂有荧光涂层,在链条的每一个特定的长度内都标有生产序号和批号,这些标记有的已连续记录制造厂商10年内生产和检测的数据。有些起重链环表面的荧光涂层在常温下可为粉红色,当温度达到225℃时,粉红色渐渐淡
First, the link part of the technical parameters Lifting chain ring spot more products, users should pay attention to the quality of their production. For example, each lifting chain generally has the serial number of the manufacturer, the inner diameter of the lifting chain has very small tolerances, and some of the chain rings are coated with a fluorescent coating and are marked with the production in each specific length of the chain Serial number and lot number, some of these marks have been continuously recorded by the manufacturer within 10 years of production and testing data. Fluorescent coatings on some of the lifting link surfaces can be pink at ambient temperatures and pinkish when the temperature reaches 225 ° C
