When excavators are moving, rotating, or performing digging operations, there are usually other workers and equipment operating on-site. Excavator operators' attention is often focused on the task at hand, and due to limited visibility, it is difficult to identify risks and take safety measures in a timely manner. This increases the likelihood of collisions between equipment and people or between different pieces of equipment, potentially causing significant damage. How can one stand out in a noisy environment and draw attention to others? A reliable warning signal is essential on every excavator.

The NANHUA AL31 sound and light alarm can reach a maximum sound level of 116dB and can be connected to the excavator's operating system. When the excavator is moving forward, reversing, rotating, or performing digging tasks, the alarm tone automatically switches through a wiring harness and can cycle through five different tones, making the warning effect more prominent.
