The invention provides a method and device for controlling stopping of a lifting system. The method includes the steps of receiving a stopping command for the lifting system; performing hovering control on a driving motor of the lifting system according to the stopping command, wherein by means of the hovering control, the driving motor is made to output the torque balanced with the lifting load of the lifting system, so that the driving motor works at a state of zero rotating speed or at a state close to zero rotating speed; performing braking control on a hydraulic braking system of the lifting system under the hovering control; monitoring working data for preset parameters of the hydraulic brake system in the braking control process; and making the driving motor stops working when the working data indicates that the braking control process is valid, so that safety parking of the lifting system can be realized.
本发明提供一种用于控制提升系统停车的方法和装置。所述方法包括:接收针对所述提升系统的停车命令;根据所述停车命令对所述提升系统的驱动电机进行悬停控制,其中,所述悬停控制使得所述驱动电机输出与所述提升系统的提升负载相平衡的力矩,以使所述驱动电机在零转速或接近于零转速的状态下工作;在所述悬停控制下对所述提升系统的液压制动系统进行施闸控制;监测所述液压制动系统在所述施闸控制过程中的针对预定参数的工作数据;当所述工作数据指示所述施闸控制过程有效时,使所述驱动电机停止工作,以实现对所述提升系统的安全停车。
