Design of Weight Limit System for Grabbing Cargo by Port Portal Crane
Grab bucket portal cranes in the process of bulk cargo unloading,when the material grabbed by grab bucket is too heavy,it will trigger the moment overload limitation,resulting in the grab bucket can not be lifted,and at this time the grab bucket needs to open the bucket repeatedly to release the material.In order to address this problem,the optimization design countermeasures of the Hopper control system is proposed,and its design principle and improvement methods are described.The experimental results show that the optimized design of the system can effectively limit the weight of the material grabbed by the grab,improve the unloading efficiency and reduce the power consumption.
