The invention relates to the related technical field of hoisting machinery, in particular to an oil cylinder system, an oil cylinder synchronous control method and device, a cargo boom and a crane. The oil cylinder system comprises a first oil cylinder, a first position sensor, a second oil cylinder, a second position sensor and an oil supply pipeline. When the oil supply pipeline is in a first state, the first oil cylinder is driven to move; when the oil supply pipeline is in a second state, the second oil cylinder is driven to move; and when the oil supply pipeline is in the third state, the first oil cylinder and the second oil cylinder are driven to move synchronously. The method comprises the steps that the oil supply pipeline is controlled to be in a third state so as to control the first oil cylinder and the second oil cylinder to move synchronously; if the synchronization error of the first oil cylinder and the second oil cylinder occurs, the oil supply pipeline can be switched to the first state or the second state, and the first oil cylinder or the second oil cylinder is controlled to move independently so as to eliminate the synchronization error.

    本申请涉及起吊机械相关技术领域,具体涉及一种油缸系统、油缸同步控制方法、装置、起重臂及起重机。其中,油缸系统包括:第一油缸、第一位置传感器、第二油缸、第二位置传感器和供油管道;当供油管道处于第一状态时,驱动第一油缸运动;当供油管道处于第二状态时,驱动第二油缸运动;当供油管道处于第三状态时,驱动第一油缸和第二油缸同步运动。方法包括,控制供油管道处于第三状态,以控制第一油缸和第二油缸同步运动;若第一油缸和第二油缸的同步出现误差,可以将供油管道切换至第一状态或第二状态,控制第一油缸或第二油缸单独运动,以消除同步误差。
