Excavator Alarm

Unlike the commonly used backup alarm, there is no such thing as a backup alarm for excavators, so the excavator alarm should be called a walking alarm.

That is, when the excavator is traveling in various directions, the alarm will emit a sound to remind the driver and surrounding personnel to pay attention to safety.

Each excavator manufacturer will select alarms with different decibels for testing in accordance with the standard ISO9533 or the domestic standard GBT 21155, Earthmoving Machinery, Forward and Reverse Audible Alarms, and Audible Test Methods.
