The construction of tunnels and subways often poses unique challenges due to the limited space available for heavy machinery and equipment. To address this issue, the tunnel arm, also known as the shortened arm, has been developed. This specialized arm is designed to operate efficiently in narrow spaces, offering increased flexibility and reduced working radius.
The tunnel arm is specifically engineered to overcome the limitations imposed by tight working conditions in tunnel and subway engineering projects. By being shorter than conventional large and small arms, it enables excavators to maneuver with greater ease, even in the most confined spaces. The reduced working radius allows for precise operation and improved control, minimizing the risk of accidental damage to surrounding structures.
