The invention provides a tower crane with height adjusting capability, which comprises a cargo boom and a lifting hook, the outer end part of the cargo boom is connected with the lifting hook through a lifting rope, and the cargo boom is a telescopic cargo boom composed of a first hollow frame, a second hollow frame, a third hollow frame and a fourth hollow frame. A first adjusting assembly is installed between the first hollow frame and the second hollow frame, a second adjusting assembly is installed between the second hollow frame and the third hollow frame, and a third adjusting assembly is installed between the third hollow frame and the fourth hollow frame. The height of the tower body is adjusted by changing the relative positions of the hollow frames in a telescopic mode, the lifting arm composed of the telescopic hollow arm frame is adopted to replace a variable-amplitude trolley to adjust the position of a lifting hook, the adjusting efficiency is high, and safety is high.
本发明提供一种具有调节高度能力的塔式起重机,包括起重臂和吊钩,起重臂外端部通过吊绳连接吊钩,起重臂由第一中空框架、第二中空框架、第三中空框架、第四中空框架组成可伸缩起重臂,第一中空框架与第二中空框架之间安装第一调节组件,第二中空框架与第三中空框架之间安装第二调节组件,第三中空框架与第四中空框架之间安装第三调节组件,本发明结构设计新颖,工作原理简单,通过伸缩改变各中空框架相对位置来调节塔身高度,同样采用可伸缩中空臂架组成的起重臂来代替变幅小车进行对吊钩位置的调整,调节效率高,且安全性高。
