起重运输机械主要用于装卸和搬运物料。它不仅广泛用于工厂、矿山、港口等生产领域,而且也应用到人们的生活领域。摩擦式吊具就是利用三个爪与筒壁之间的摩擦力调运圆钢,吊具三个爪对筒壁的正压力必须足够大,才能完成调运工作,所以,本文将对吊具爪对筒壁的正压力进行计算。
Lifting and transport machinery is mainly used for loading and unloading and handling of materials. It is not only widely used in factories, mines, ports and other production areas, but also applied to people’s lives. Friction spreader is the use of friction between the three claws and the wall of the transfer of steel bar, spreader three claws on the wall of the positive pressure must be large enough to complete the transfer work, so this article spreader claw pair The pressure on the wall is calculated.
