The invention provides a high-altitude tower crane with a foldable hydraulic telescopic boom, which is mounted at the top of a tower crane standard knot and comprises a base and an upper chassis rotationally mounted on the base, a balance arm is fixedly mounted at the rear end of the upper chassis, and a telescopic boom is rotationally mounted above the upper chassis; the telescopic cargo boom comprises a plurality of large arms with sleeve structures and a plurality of telescopic oil cylinders; the pipe diameters of the large arms are gradually reduced in the extending direction, and the fixed ends and the extending ends of the telescopic oil cylinders are connected with the two adjacent large arms correspondingly. The big arm comprises a supporting big arm connected with the front end of the upper chassis, the front end, away from the balance arm, of the upper chassis is rotationally connected with a supporting hydraulic cylinder, and the telescopic end of the supporting hydraulic cylinder is rotationally connected with the end, away from the upper chassis, of the supporting big arm. The telescopic arm which is hydraulically telescopic is applied to the tower crane, and is matched with the supporting hydraulic cylinder for realizing elevation amplitude variation, so that lifting and hoisting are realized under the condition of height limitation, and the device is suitable for height limitation places, such as height limitation of airlines, around airports, is convenient and practical, and has relatively strong popularization significance.
本发明提供一种具有可折叠液压伸缩臂的高空塔机，安装于塔机标准节顶部，包括底座和旋转安装于底座上的上底盘，上底盘的后端固定安装有平衡臂，上方转动安装有伸缩起重臂；伸缩起重臂包括多根套管结构的大臂和多根伸缩油缸；多根大臂沿延伸方向管径逐级缩小，多根伸缩油缸的固定端与延伸端分别与相邻的两个大臂连接；大臂包括与上底盘前端连接的支撑大臂，上底盘远离平衡臂的前端转动连接有支撑液压缸，支撑液压缸的伸缩端与支撑大臂远离上底盘的一端转动连接；设置液压伸缩的伸缩臂运用于塔机上，同时配合实现仰角变幅的支撑液压缸，实现在限制高度情况下进行起升吊装，适用于机场周边因飞机航线限高等限高场所，方便实用，具有较强的推广意义。
