With their compact size, Demolition Robot can perform tremendously well especially for tunneling industry. A new passageway was created to the existing Smart Tunnel, the limestone and rocks has to be cleared during this process.
In tunneling works, working access is generally tight and confined, a standard excavator or backhoe could not access the area. The “arm” is less flexible therefore it is not able to swing left and right in such working condition. Air ventilation in tunnel is poor too, the combustion from the excavators will be harmful to the operators and workers.
