The invention provides a forklift potential energy recovery system, which belongs to the technical field of energy recycling, comprises a main portal lifting oil cylinder, an auxiliary portal lifting oil cylinder, an auxiliary portal rotating motor and an auxiliary portal rotating oil cylinder, and is characterized by further comprising an energy recovery and release system, the energy recovery and release system comprises a hydraulic pump motor, a motor generator and a storage battery, the hydraulic pump motor is respectively connected with the oil tank, the main gantry lifting oil cylinder, the auxiliary gantry lifting oil cylinder, the auxiliary gantry side displacement motor and the auxiliary gantry rotating oil cylinder; the hydraulic pump motor, the electric generator and the storage battery are sequentially connected; the energy recovery and release system has the advantages that energy recovery can be carried out on pressure oil flowing back to the oil tank when the main portal frame falls back, the auxiliary portal frame falls back and the auxiliary portal frame rotates by arranging the energy recovery and release system, and energy loss caused by circulation of the pressure oil is avoided.

    本发明提供了一种叉车势能回收系统,属于能量循环利用技术领域,包括主门架举升油缸、副门架举升油缸、副门架旋转马达和副门架旋转油缸,特点是还包括能量回收与释放系统,能量回收与释放系统包括液压泵马达、电动发电机与蓄电池,液压泵马达分别与油箱、主门架举升油缸、副门架举升油缸、副门架侧移马达和副门架旋转油缸相连,液压泵马达、电动发电机、蓄电池顺序连接;优点是通过设置有能量回收与释放系统可对主门架回落、副门架回落以及在副门架旋转时流回油箱的压力油进行能量回收,避免了压力油流通时造成的能量损失。
