Lifting and hanging
举挂───Lifting and hanging
technical difficult point and general situation of the electromagnetic hanging , releasing and lifting machine for the micrograv ity falling tower are discussed.───论述了微重力落塔落舱电磁悬吊、释放、提升控制系统的关键技术 ，以及电磁释放过程的特性分析和微重力落塔实际试验情况 。
It was only when the hull was hanging freely from the lifting frame, clear of the seabed and the suction effect of the surrounding mud, that the salvage operation progressed to the second stage.───只有当船体从升降架上自由悬挂，脱离海床和周围泥浆的吸力作用时，打捞工作才进入第二阶段。
Formula for calculating standard values of allowable concentrated loads in railway of hanging lifting equipment is introduced by using reversed calculation and their application.───介绍了采用反算法计算悬挂运输设备轨道的容许集中荷载标准值的公式及其应用图表。
