The composition of the crane angle indicator：

The amplitude indicator of a small mobile engineering crane consists of a dial indicating the angle and a vertical pointer that can rotate freely. It is placed at the lower end of the boom for easy observation by the driver and is used to indicate the inclination angle of the boom during operation. The amplitude indicator of large and medium-sized cranes is used to indicate the inclination angle of the boom and the lifting capacity at this angle. Its structure is similar to the angle detection device.

Working principle of the crane angle indicator：

Data processing and calculation are performed based on the detection results of arm length and boom inclination, and then displayed.
