Introduction to reactive power grab scale:

The reactive power grab scale is used for measuring tower type reactive power grab cranes. There are generally two types: one is suitable for measuring small cranes under 5t, which places a special measuring head on the head of the crane, and the display instrument can be placed in the cab or other places, connected by wires in the middle, with high measurement accuracy.

Another type of double cable grab crane suitable for large ports has high-precision sensors and transmitters on each lifting rope. The force on each steel rope is transmitted to the receiving instrument, which processes the data through a computer and displays it for printing.

Weighing principle

The reactive power grab scale is a measuring and monitoring system specifically designed for reactive power grab cranes and during the loading and unloading of bulk materials. It features a specially designed measuring head placed at the head of the crane boom, and a display control instrument that can be placed in a suitable position inside the cab or below the crane (with a glass window and locking instrument box). The scale is specially designed to overcome the severe shaking during grab operation and the inaccurate measurement caused by irregular amplitude operations during boom operation. It automatically completes the measurement of each ship's cargo and prints a list. It is an efficient, pure dynamic weighing system.
