Detailed line crane remote monitoring system used in the process of the whole lifting the use of the cable greatly reduced, when design the bus technology and the wireless control mode are used together, at work just need use twisted-pair cable can be completed, thus greatly improves the reliability, reduce the cost and materials, such as cable, than the old crane save more than 80%, maintenance is convenient.Line is one of the largest hoisting equipment usage, and most of the current bridge crane using for production until the 1980 s, except a few retired scrap, most are still using, aging problem is increasingly outstanding, are used on the basis of inadequate, the risk is bigger.But with the development of modernization in our country, the national performance requirements more and more high, the safety of the hoisting machinery of the original control system is more and more cannot satisfy the security requirements.We need new equipment to meet the needs of us, this time line crane remote monitoring system is applied.
