介绍了一种新型多位一体结构的平头塔机,该结构将起升机构、变幅机构、回转机构、变幅小车、吊钩总成、电控系统、驾驶室、力矩限制器、起重量限制器安装在回转上支承架上,其与回转支承、回转下支承架集成一体化制造安装,有效解决了传统塔机维修困难,存放管理混乱,运输成本高以及现场拆装工艺繁琐的问题。 A new type of flathead tower crane with multi-position integrated structure is introduced. The structure consists of a hoisting mechanism, a luffing mechanism, a revolving mechanism, a luffing trolley, a hook assembly, an electronic control system, a cab, a torque limiter, The limiter is installed on the slewing upper supporting frame and is integrated and integrated with the slewing bearing and the slewing lower supporting frame to effectively solve the problems of the traditional tower crane such as the maintenance difficulty, the storage management disorder, the high transportation cost and the tedious disassembly and assembly process on site.
