The telescopic arm is also equipped with a safety valve, which, in the unlikely event of a damaged cylinder, will prevent any other impact on the machine or the environment.
WARNING SAFETY ALARMS
The safe performance of the excavator with telescopic arm is aided by the use of warning lights and safety alarms. For example, if either of the two ropes were to break suddenly or extend too far, an indication light and a warning buzzer would alert the operator immediately. In addition, a warning buzzer will alert the operator if too much pressure is applied once the clamshell bucket has reached the ground and is excavating the material.
