The invention relates to the field of hoisting equipment, in particular to a portal crane suitable for multi-working-condition hoisting operation. According to the technical scheme, the crane comprises a cross beam part and two sets of supporting leg parts, each supporting leg part comprises a crane top seat and a crane base, and each supporting leg part further comprises two sets of supporting arms and two sets of hydraulic cylinders. The two supporting arms are hinged to the two ends of a crane base correspondingly, and the two hydraulic cylinders are hinged to the middle of the crane base and used for supporting the corresponding supporting arms. The top end of each supporting arm is hinged to a hydraulic telescopic device, and the other end of each hydraulic telescopic device is hinged to the crane footstock. By adjusting the height of the top seats of the crane and the distance between the top seats of the crane, the occupied space of the crane is reduced, work under different working conditions is facilitated, and the crane is suitable for a small-space working environment.

    本发明涉及起重设备领域,尤其涉及一种适应多工况起重作业的门式起重机。其技术方案包括横梁部分以及支腿部分,所述支腿部分设置有两组,所述支腿部分包括起重机顶座以及起重机底座,所述支腿部分还包括:支撑臂以及液压缸,所述支撑臂以及液压缸均设置有两组,两组所述支撑臂分别铰接在起重机底座的两端,两组所述液压缸铰接在起重机底座的中部用于对对应的所述支撑臂提供支撑;每个所述支撑臂的顶端均铰接有液压伸缩装置,液压伸缩装置的另一端与所述起重机顶座铰接。本发明通过调节起重机顶座的高度以及起重机顶座之间的间距,从而使起重机的占用空间减少,有利于在不同的工作情况下的工作,适用于小空间的工作环境。
