北仑港发电厂二期２４０ｍ集束式烟囱施工中，操作平台电动提升系统的提升架与提升机械传动装置是电动升模的关键，将提升架设计为一个大刚度的几何不变体，提升架通过滚轮套合于操作架内侧的槽钢上，与之互为轨道，交替上升。
During the construction of the 240m bundling chimney of Phase II of Beilungang Power Plant, the lifting frame of the electric lifting system of the operation platform and the hoisting mechanical transmission device are the key to the electric lifting mode. The lifting frame is designed as a geometric rigid invariant body and the lifting frame passes through. The rollers are fitted on the channel steel on the inner side of the operation frame and are alternately raised.
