哈尔滨市第一建筑工程公司动力站为配合省电视台工程高层框架滑模施工,对国产2-6吨塔式起重机进行了改造,设计试制了2台固定式提升塔式起重机,通过采用卷扬机提升的办法,将2-6吨塔式起重机加长一段滑升节,通过由标准节组成的塔身(套架)逐步提升接高。为此,原吊机的第一节架下龙门架、基础部分全部不用,即在操纵室下原第一节架处增
The power station of Harbin No. 1 Construction Engineering Co., Ltd. cooperated with the construction of the high-level frame sliding mode for the provincial TV station project. The 2-6-ton tower crane made in China was rebuilt, and two fixed-lift tower cranes were designed and trial-produced. In the approach, a 2-6-ton tower crane is extended by a section of sliding section, and the height is gradually increased by a tower body (a frame) composed of standard sections. For this reason, the first section of the original crane under the gantry and all the basic parts are not used, that is, the original first section under the control room is increased.
