多数起重设备在取料之后即开始垂直或垂直兼有水平的工作行程，到达目的地后卸载，再空行程到取料地点，完成一个工作循环，然后再进行第二次吊运或搬运。一般来说，起重设备工作时,取料、运移和卸载是依次进行的,各相应机构的工作是间歇性的。起重设备主要用于搬运成件物品，配备抓斗后可搬运煤炭、矿石、粮食之类的散状物料，配备盛桶后可吊运钢水等液态物料。有些起重机械如电梯也可用来载人。在某些使用场合，起重设备还是主要的作业机械，例如在港口和车站装卸物料的起重机就是主要的作业机械。流水槽模具 u型槽模具 电缆槽模具 隔离墩钢模具 护坡砖模具 钢制闸门 螺杆式启闭机 卷扬式启闭机
Most lifting equipment start vertical or both vertical and horizontal working stroke after reclaiming, unload after reaching the destination, empty stroke to the reclaiming place, complete a working cycle, and then carry out the second lifting or handling. Generally speaking, when the lifting equipment works, the reclaiming, transportation and unloading are carried out in turn, and the work of each corresponding mechanism is intermittent. The lifting equipment is mainly used for handling finished goods. When equipped with grab bucket, it can handle bulk materials such as coal, ore and grain, and when equipped with bucket, it can lift liquid materials such as molten steel. Some lifting appliances such as elevators can also be used to carry people. In some applications, hoisting equipment is still the main operation machinery. For example, cranes for loading and unloading materials in ports and stations are the main operation machinery.
