I. Introduction
Reactive grab scales are used for the metering of tower-type reactive grab cranes. Generally there are two types: one is suitable for the metering of small cranes below 5t, which places the special metering head at 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 metering accuracy.
The other one is suitable for large double cable grab crane in port, there are high precision sensors and transmitters on each rope, the force of each rope is transmitted to the receiving instrument respectively, the instrument carries out computer processing and displays the printed data.
II. Working principle
The reactive grab scales are specially designed to be used in reactive grab cranes to monitor the measurement of bulk materials during loading and unloading, with a special measuring head placed at the head of the crane's lifting arm and a display and control instrument that can be placed in the cab or at a suitable position in the lower part of the crane (with glass window and locking instrument box) and are specially designed to overcome the violent shaking of the grab and the inaccurate measurement caused by the irregular amplitude operation of the crane arm, and to automatically complete It is a highly efficient, purely dynamic weighing system, with automatic printing of a list of each ship's cargo.
