摘要
随着变频器的日益普及,其在港口设备上得到了广泛的应用,门座式起重机也普遍采用了变频控制技术。了解门座式起重机工况,合理的计算、选择变频控制系统关系到门座式起重机运行的安全性和可靠性。
Along with popularizing of inverter increasingly, inverter is widely used in many harbour facilities such as portal crane. For the safety and reliability of running portal crane, it is very important to understand working condition of portal crane, to calculate reasonably, to select frequency changed controlling system properly.
