The invention relates to the technical field of hydraulic cranes, in particular to a linear lifting hydraulic crane which comprises a supporting base, reinforcing supporting assemblies are rotationally connected to the four corners of the supporting base correspondingly, weight boxes are fixedly installed at the front end and the rear end of the supporting base correspondingly, and a mounting frame is fixedly installed at the top of the supporting base; a rotary table is rotationally connected to the top of the mounting frame, a telescopic rod is fixedly mounted at the top of the rotary table, and a lifting hydraulic cylinder is fixedly mounted on the outer side of the telescopic rod. The lifting device has the beneficial effects that multiple groups of additional supporting points can be provided through the design, the balance is ensured to be more stable, meanwhile, the supporting points can adapt to the uneven ground, the applicability is greatly improved, the phenomenon that the gravity center is unstable when goods are lifted and transferred is avoided, the stability in the lifting process is further ensured, and the lifting efficiency is improved. And the goods can be flexibly transferred, the hoisting operation is more balanced and stable, and the safety of the hoisting operation is greatly improved.
本发明涉及液压吊机技术领域,具体涉及一种可以直线升降的液压吊机,包括:支撑底座,支撑底座的四个拐角处均转动连接有加强支撑组件,支撑底座的前后两端均固定安装有配重箱,支撑底座的顶部固定安装有安装架,安装架的顶部转动连接有转台,转台的顶部固定安装有伸缩杆,伸缩杆的外侧固定安装有升降液压缸。本发明的有益效果是:通过设计能够提供额外的多组支撑点且保障平衡更加稳定,同时支撑点能够适应不平整的地面适用性大大提升,避免在对货物进行提升并进行转移时发生重心不稳的现象,进而保障了起吊过程的稳定性,而且能够灵活转移货物且让起吊作业更加平衡稳定,大大提高了起吊作业的安全性。
