Crane Weighing – Integral Type

Best Allternate Solution for expensive imported Hanging Crane Weighing System

Electronic Crane Weighing Systems are ideal equipment to weigh molten metal and other raw materials such as scrap, pig iron, borings, CRC, Returns. Pin type Load cell is installed in the equalizing pulley on top of the Crane . The load on the crane hook is sensed by measuring the load cell output is connected to weight indicator and transmitted through Radio Frequency (RF). Wireless Large figure display is provided for receiving and displaying the weight information. Wireless Remote pendant is provided to Tare, Zero and Calibrate the System.
