The invention relates to the technical field of engineering machinery, and discloses a lorry-mounted crane, a lorry-mounted crane operation method and a lorry-mounted crane transport vehicle. The lorry-mounted crane comprises a base assembly, a stand column, an arm frame assembly, an auxiliary supporting mechanism and a variable-amplitude driving mechanism. The stand column is arranged on the base assembly. An outer arm frame of the arm frame assembly is hinged to the stand column, a first hinge part and a second hinge part are arranged on the abdomen of the outer arm frame, and the second hinge part is located on the side, away from the stand column, of the first hinge part; the other end of the auxiliary supporting mechanism is hinged with the outer arm frame; one end of the variable-amplitude driving mechanism is hinged to the stand column, and the other end of the variable-amplitude driving mechanism is selectively hinged to the first hinge part or the second hinge part. When the other end of the variable-amplitude driving mechanism is hinged to the second hinge part, the variable-amplitude driving mechanism can drive the arm support assembly to swing towards the lower portion of the horizontal plane to be folded and put away. The lorry-mounted crane disclosed by the invention is better in trafficability, and facilitates disassembly and assembly of auxiliary accessories.

    本申请涉及工程机械技术领域,公开一种随车起重机、随车起重机作业方法及随车起重运输车。随车起重机包括底座总成、立柱、臂架总成、辅助支撑机构和变幅驱动机构;立柱设置于底座总成上;臂架总成的外臂架铰接于立柱上,外臂架的腹部上设有第一铰接部和第二铰接部,第二铰接部位于第一铰接部远离立柱的一侧;辅助支撑机构的一端与立柱铰接,另一端与外臂架铰接;变幅驱动机构的一端与立柱铰接,另一端可选择性地与第一铰接部或第二铰接部铰接连接;其中,在变幅驱动机构的另一端与第二铰接部铰接时,变幅驱动机构可驱动臂架总成朝水平面下方摆动进行折叠收起。本申请公开的随车起重机通过性更好,便于辅助配件的拆装。
