The invention relates to a European style crane capable of being jacked. The European style crane comprises a cross beam, an electric trolley is movably mounted on the cross beam, a crane is mounted on the lower surface of the electric trolley, supporting mechanisms are mounted on the lower surfaces of the two ends of the cross beam correspondingly, bases are mounted at the bottoms of the two supporting mechanisms, lifting mechanisms are mounted at the tops of the two bases, the outer sides of the bottoms of the supporting mechanisms are sleeved with the lifting mechanisms, and a lower short beam and a lower long beam are mounted on the edge of the upper surface of the base correspondingly, so that the lifting mechanisms have the function of being disassembled from the base, and the lifting mechanisms can be disassembled from the base when the height of the supporting mechanisms does not need to be adjusted; the supporting mechanisms are clamped through supporting air cylinders, then the height of the supporting mechanisms is adjusted through lifting air cylinders, and the supporting mechanisms are assembled and disassembled through assembling and disassembling air cylinders, so that the height of the supporting mechanisms is rapidly increased or decreased, the height of the European style crane is adjusted, self-jacking of the European style crane is achieved, different production requirements are met, and the application range is expanded.

    本发明涉及一种自身可顶升的欧式起重机,包括横梁,横梁上活动安装有电动小车,电动小车的下表面安装有吊机,横梁的两端下表面分别安装有支撑机构,两个支撑机构的底部安装有底座,两个底座的顶部均安装有升降机构,升降机构套装在支撑机构的底部外侧,下短梁和下长梁分别安装在底座的上表面边缘处,从而使升降机构具有从底座上拆装的功能,使得在不需要调整支撑机构的高度时可将升降机构从底座上拆除,通过支撑气缸夹持住支撑机构,随后通过升降气缸调节支撑机构的高度,并通过装卸气缸对支撑机构进行装卸,从而快速增减支撑机构的高度,对该欧式起重机进行高度调节,实现其自身顶升,从而适应不同的生产需求,扩大适用范围。
