The invention relates to the technical field of portal cranes, in particular to a rubber-tired universal portal crane. Comprising two lifting devices arranged in a central symmetry mode, two cross beams connected between the two lifting devices and two hoisting parts capable of walking in the length direction of the cross beams, the lower ends of the lifting devices are connected with a moving mechanism, and each lifting device comprises two door-shaped lifting frames rotationally connected to the upper portion of the moving mechanism; the two door-shaped lifting frames can be unfolded in the length direction of the cross beam to form a V shape. When the device is unfolded, the adjacent door-shaped lifting frames of the two lifting devices are in vertical lap joint, the cross beams are separated to form connecting sections and extending sections, one hoisting part is vertically connected between the ends of the two connecting sections, and the connecting sections of the two cross beams are arranged in a Z shape. The crane is convenient to deform, the moving range of goods hoisted by the crane can be effectively extended, meanwhile, the gravity center of equipment is lowered, and stable operation of the equipment is guaranteed.
本发明涉及门式起重机技术领域,具体地说就是一种轮胎式万向门式起重机。包括两中心对称设置的举升装置、连接于两个举升装置之间的两条横梁和可沿横梁长度方向行走的两个吊装部,所述举升装置的下端连接有移动机构,所述举升装置包括两个转动连接于移动机构上部的门型举升架,所述两个门型举升架可沿横梁的长度方向展开呈V型;装置展开时,两个举升装置的相邻门型举升架垂直搭接,所述横梁分离形成连接段和延长段,其中一个所述吊装部垂直连接于两个连接段的端部之间,使两横梁的连接段呈Z型设置。本申请的起重机变形方便,能够有效延长起重机吊运货物的移动范围,同时降低设备重心,保障设备的稳定运行。
