In order to solve the problems of slow response,poor accuracy,low reliability and easy damage of the traditional measurement method of container crane on shore,a load monitoring system of container crane based on spunlock weighing was adopted.The spinner load weighing system is composed of force measuring unit,data processor and communication bus in the system,alarm display unit in the driver's cab,external communication bus of the system and data storage unit,which is used to measure and monitor the lifting quality of the lifting gear of the container crane.The sensor of the force measuring unit is integrated in the spinner of the container crane.The system has the advantages of fast response,high precision,strong reliability,easy damage,and so on.At the same time,it can monitor and display the load on each spreader's spinner in real time,and store the quality data.When the abnormal spinner load is detected,the system can quickly make sound and light alarm,or directly lock the spreader drive motor to prevent abnormal lifting,prevent accidents,and improve the safety of container cranes.In addition,the use of spinlock load weighing system can ensure that the rope of the lifting mechanism will not be deformed and damaged due to excessive weight,and further improve the safety of the container crane on the shore.
