东方航空公司４０号维修机库３２００ｔ超大型钢屋盖整体提升中，通过计算机系统实现千斤顶集群作业动作控制、吊点同步提升高差控制、吊点提升力均衡控制及操作台实时监控，解决了吊点多且分布不均匀、载荷差异大、液压机构离散性大及现场露天、风雨影响等问题，施工偏差和到顶后定位偏差小于设计限定值。
In the overall upgrade of the 3200t super steel roof of the maintenance hangar No. 40 of Eastern Airlines, the jacking cluster operation and operation control, lifting point synchronous elevation height control, hoisting point lifting force balance control, and console real-time monitoring were implemented through the computer system, and the crane was solved. There are many problems such as uneven distribution, large load variation, large dispersion of hydraulic pressure, and open air and wind and rain on the site. Construction deviation and positioning deviation after reaching the ceiling are less than the design limit.
