The invention provides a control system for loading and arm retracting of a crane and an automobile crane, the control system comprises a crane jib, a rotation detection device, an amplitude variation detection device and a control device, the crane jib is carried on a rotation device and carries an amplitude variation device; the control device communicates with the rotation device, the amplitude variation device, the rotation detection device and the amplitude variation detection device and is configured to receive the real-time rotation position sent by the rotation detection device and the real-time amplitude variation position sent by the amplitude variation detection device and control the rotation device to rotate according to the preset rotation reference position and the real-time rotation position. And according to the preset amplitude variation reference position and the real-time amplitude variation position, the amplitude variation device is controlled to perform amplitude variation motion, so that the axis of the crane jib is aligned with the center line of the jib bracket. By means of the technical scheme, the axis of the crane jib can be automatically aligned with the center line of the jib support, and therefore the phenomenon that the jib support is cracked up when an operator operates independently is avoided.

    本发明提供一种用于起重机上车收臂的控制系统及汽车起重机,控制系统包括起重机吊臂、回转检测装置、变幅检测装置和控制装置,起重机吊臂搭载于回转装置上并搭载有变幅装置,控制装置分别与回转装置、变幅装置、回转检测装置以及变幅检测装置通讯并被配置为:接收回转检测装置发送的实时回转位置和变幅检测装置发送的实时变幅位置,根据预设回转基准位置和实时回转位置控制回转装置进行回转运动,根据预设变幅基准位置和实时变幅位置控制变幅装置进行变幅运动,以使起重机吊臂的轴线与吊臂支架的中心线对齐。通过本发明的技术方案,能够使得起重机吊臂的轴线与吊臂支架的中心线实现自动对齐,从而避免操作手单独操作时出现撞坏吊臂支架的现象。
