Introduction of excavator tunnel boom

The tunnel arm is specifically engineered to operate efficiently in narrow spaces where conventional large and small arms may struggle. By being shorter in length, it allows excavators to maneuver with greater ease, even in the most confined areas. This increased maneuverability enables construction crews to work effectively in spaces with limited overhead clearance, tight corners, or restricted access points.

The tunnel arm offers construction crews a high degree of flexibility and adaptability. Its compact size and specialized design make it suitable for a variety of applications within tunnel and subway projects. Whether it's excavating, drilling, or transporting materials, the tunnel arm can be easily maneuvered to perform a wide range of tasks, contributing to increased project efficiency and productivity.
