[0002] In the loading and unloading operations at the port terminal, cranes are needed for lifting, transshipment, loading and unloading of goods. In order to prevent overloading that may cause damage to the crane structure, equipment failure or even safety accidents, cranes operating in the port will be equipped with weighing sensors to weigh the goods during the lifting process and alarm. The existing cranes with weighing alarm function are mainly composed of a bridge, a lifting mechanism, and an operating mechanism. The operating mechanism drives the bridge and the lifting mechanism to the appropriate position to lift the goods, and the lifting mechanism lifts and lowers the goods. A weighing sensor is installed inside the lifting mechanism to avoid overloading of the crane.

[0003] Existing application number CN202320803696.6 The utility model discloses a port crane with a weighing alarm function in the field of port crane technology, including a port crane body, a cable and a lifting hook. The port crane body is connected to a fixed box through a cable, a weighing sensor is provided at the top of the inner cavity of the fixed box, a fixed plate is provided at the bottom of the weighing sensor, a pressure plate is provided at the bottom of the inner cavity of the fixed box, multiple groups of telescopic rods are provided between the pressure plate and the fixed plate, and springs are provided on the outer walls of the telescopic rods. A battery pack and a 5G signal transmission module are also provided on the right side of the inner cavity of the fixed box, and the electrical end of the 5G signal transmission module is electrically connected to the electrical end of a display screen in an operating room on the port crane body, the bottom end of the pressure plate is connected to a mounting seat, and a connecting rod is installed in the mounting seat. The utility model can know the weight of the hoisted object in real time through the display screen on the crane. When the weight exceeds the set value, an alarm prompt will appear on the display screen, which can effectively prevent the crane from being damaged due to excessive hoisting weight.

[0004] Based on the above, the existing cranes with weighing alarm function are mainly installed in ports near the sea and river coasts. Therefore, most ports have heavy humidity, especially ports near the sea. The high humidity and high salt content can easily corrode the steel cables inside the lifting mechanism, affecting the normal operation of the crane. The steel cables need to be maintained frequently to reduce the corrosion rate of the steel cables. The steel cable maintenance process is relatively cumbersome, which affects the use of the crane hoisting and increases the workload of the staff. Utility Model Content
