The invention relates to the field of cranes and discloses a folding lorry-mounted crane which comprises a base, supporting leg oil cylinders are symmetrically arranged on the left side and the right side of the base, a slewing bearing is rotationally connected to the center of the top of the base, a connecting frame is installed at the top of the slewing bearing, a rotary table is arranged on the right side of the connecting frame, and a pitching oil cylinder is arranged on the left side of the rotary table. A telescopic oil cylinder is arranged on the top of the telescopic arm, a variable-amplitude oil cylinder is installed on the left side of the rotary table, a winch is installed on the right side of the telescopic arm, and a lifting hook is arranged at the bottom of the winch. According to the folding lorry-mounted crane disclosed by the invention, the crane can be retracted to a minimum state when an automobile chassis moves, so that the boundary dimension of equipment is greatly reduced, and when the lorry-mounted crane works, higher working height can be achieved by adjusting the backward pitching angle of the equipment and adjusting the telescopic length of an oil cylinder on a rotary table of the crane; and the working radius is larger.

    本发明公开了一种折叠式随车起重机,本发明涉及起重机领域,包括基座,所述基座的左右两侧对称设置有支腿油缸,基座顶部的正中转动连接有回转支承,回转支承的顶部安装有连接架,连接架右侧设置有转台,转台的左侧设置有俯仰油缸,俯仰油缸的左侧设置有伸缩臂,伸缩臂的顶部设置有伸缩油缸,转台的左侧安装有变幅油缸,伸缩臂的右侧安装有卷扬机,卷扬机的底部设置有吊钩。本发明所述的一种折叠式随车起重机,此起重机可以在汽车底盘移动的时候,缩到最小状态,大大减小的设备的外形尺寸,随车起重机工作时,可以通过调节设备的后仰角度、调节起重机转台上油缸的伸缩长度,达到更高的工作高度,更大的工作半径。
