The invention belongs to the technical field of port hoisting, and particularly relates to a cargo weight grabbing limiting system, which comprises a PLC (Programmable Logic Controller) of which the input end is connected with a touch screen HMI (Human Machine Interface); the support transmission HOLDDRIVE is connected with the output end of the PLC and sends a torque starting signal TORQUEOPEN to control a first motor to work; when the second motor is started, a drive CLOSEDRIVE is closed, a speed set value SPEEDREF from the support transmission HOLDDRIVE is received, and a speed starting signal SPEEDOPEN is sent out to control the second motor to work; and the grab bucket is jointly driven by the first motor and the second motor to work. The problem that goods cannot be lifted due to overload when the grab bucket grabs the goods can be solved, and the grab bucket has good market application prospects.
本发明属于港口起重技术领域,具体涉及一种货物重量抓取限制系统,包括:PLC,其输入端连接触摸屏HMI;支持传动HOLD_DRIVE,连接所述PLC的输出端,并发出扭矩开启信号TORQUE_OPEN控制第一马达工作;关闭驱动CLOSE_DRIVE,接收来自所述支持传动HOLD_DRIVE的速度设定值SPEED_REF,并发出速度开启信号SPEED_OPEN控制第二马达工作;抓斗,由所述第一马达和所述第二马达共同驱动工作。本发明可以解决抓斗抓取货物时出现超载问题导致货物无法被提升的问题,具有较好的市场应用前景。
