The new-generation four-reel ship-unloader adopts the intelligent differential control system with proprietary intellectual property rights .Four standard reducers are used to replace the two enormous and heavy differential gearboxes of the mechanical differential ship-unloader , optimizing the structure , facilitating operation maintenance , and reducing cost.The paper introduces the working principle of new-generation four-reel ship-unloader and its application in power plant and port terminal.%新一代四卷筒卸船机采用完全自主知识产权的智能差动控制系统,用4台标准的减速器替代了机械差动式卸船机2台庞大笨重的差动齿轮箱,相比传动机型,在整机结构优化、 操作维护便利、 使用成本等方面都有较大改善.文中介绍了新一代四卷筒卸船机的工作原理及其在电厂和港口码头的应用.
