The invention relates to hoisting equipment, in particular to an automobile crane and a rear supporting leg assembly thereof. The rear supporting leg assembly comprises a horizontal supporting leg, asupporting leg, a hinge seat and a limiting structure, the hinge seat is arranged at the telescopic end of the horizontal supporting leg, the supporting leg is hinged to the hinge seat through a supporting leg hinge shaft, the supporting leg hinge shaft extends in the telescopic direction of the horizontal supporting leg, and a limiting pin shaft is detachably inserted in the hinge seat; and whenthe supporting leg is in a vertical state, the supporting leg is limited on the two sides of the rotating direction of the supporting leg. When supporting is needed, the limiting pin shaft is mountedand conduct limiting on the two sides of the supporting leg, so that the supporting leg is kept vertical; and when the automobile crane needs to turn in a narrow occasion, the limiting structure is dismantled, the supporting leg is obliquely supported on the ground, and after the supporting leg extends, the supporting leg pushes the tail of the automobile crane to enable the automobile crane to rotate by a certain angle to assist the automobile crane in steering, so that the passing performance of the automobile crane is improved.
本发明涉及一种起重设备,尤其涉及一种汽车起重机及其后支腿组件。后支腿组件包括水平支腿、支撑支腿、铰接座和限位结构,水平支腿的伸缩端处设置有铰接座,支撑支腿通过支腿铰接轴与铰接座铰接,支腿铰接轴沿水平支腿伸缩方向延伸,铰接座上可拆插装有限位销轴,当支撑支腿处在竖直状态时,在支撑支腿转动方向的两侧对支撑支腿进行限位。当需要支撑时,安装限位销轴,限位销轴在支撑支腿两侧进行限位,使支撑支腿保持竖直;当需要在狭小的场合转弯时,拆除限位结构,使支撑支腿倾斜支撑在地面上,支撑支腿伸长后,支撑支腿将推动汽车起重机的尾部使汽车起重机转动一定角度,来辅助汽车起重机进行转向,进而提高汽车起重机的通过性能。
