The grab scale presses the entire trolley onto the weighing platform. When the crane starts measuring, the instrument automatically tracks the zero position, which means the weight of the grab bucket is removed as tare weight. After the sensor senses the pressure, it will output a current signal to the instrument. The instrument then drives the large screen display, printer, and computer storage functions through its own external output interface.
