The invention provides a lifting device of an automobile crane, and relates to the technical field of automobile cranes. The lifting device of the automobile crane comprises a base and a working table, a rotary hydraulic motor is connected between the base and the working table, an oil tank, a cab and a hydraulic source are arranged on the upper side face of the working table, a first winch is arranged on the oil tank, a steel cable is wound on the first winch, and a second winch is arranged on the working table. The hydraulic lifting device is characterized in that a reverse rotation blocker is arranged between the workbench and the base and located on the outer side of the rotary hydraulic motor, a swing arm driving assembly is arranged on the hydraulic source, and the swing arm driving assembly is connected with the lifting arm in a driving mode. The movement of the steel cable is hindered under the action of the locker, the steel cable is further hindered by matching with the safety auxiliary assembly, in addition, after the corresponding lower lock head is inflated and quickly flies to the hook, the lower lock head and the hook are matched together, then a rope of the second winch connected with the lower lock head assists the steel cable, and the lifting safety is improved.

    本发明提供一种汽车起重机起重装置,涉及汽车起重机技术领域。该汽车起重机起重装置,包括底座和工作台,所述底座和工作台之间连接有回转液压马达,所述工作台的上侧面设置有油箱、驾驶室和液压源,所述油箱上设置有第一卷扬机,所述第一卷扬机上卷绕有钢索,其特征在于:所述工作台和底座之间且位于回转液压马达的外侧设置有反转阻碍器,所述液压源上设置有摆臂驱动组件,所述摆臂驱动组件驱动连接起重臂。通过锁紧器的作用对钢索的运动进行阻碍,以及配合安全辅助组件处对钢索的进一步阻碍,另外对应的下锁头在充气快速飞向挂钩后,两者配合到一起,进而由下锁头连接的第二卷扬机的绳子对钢索进行辅助,提高了起吊的安全性。
