Excavation work in confined spaces such as tunnels, mines, and underground construction sites requires specialized equipment that can navigate tight spaces safely and efficiently.

Tunnel boom excavators significantly enhance productivity in confined spaces. Their specialized configuration enables them to work more efficiently and effectively, even in challenging environments. By utilizing the tunnel boom, excavators can maneuver and perform excavation tasks with precision, minimizing downtime and maximizing the amount of work accomplished within a given timeframe. The increased productivity translates to cost savings and faster project completion.

1. On the same machine, tunnel arm can obtain greater lifting capacity than the standard arm, the opening angle between boom and arm can reach 180 degrees, which improves work efficiency. 

2. The upper and lower cover plates are thicker.
3. The arm is filled with iron sand to reduce vibration
4. Enlarge cylinders to avoid its damage by excessive vibration

5. Multi-layer welding of pipe connectors to reduce the risk of oil leakage
