As the most commonly used transmission part of hoisting machinery, steel wire rope is widely used in port cranes. Almost all the load-bearing or lifting work can not be separated from steel wire rope, especially in metallurgy, construction, mining, port freight and other industries. With the rapid development of economy and trade, the logistics industry is becoming more and more vigorous. The increase of port freight volume leads to the increasing use intensity and frequency of crane wire rope. We know that the use of steel wire rope is closely related to the safety of the port. Because of the structure of steel wire rope and the existence of non-standard use, it is very easy to cause the occurrence of steel wire rope fracture and other risks, and then cause huge personal and property losses. Therefore, in the safety management of the port, we must strengthen the supervision of the safe use of steel wire rope.
