Excavator tunnel arm is a type of boom configuration for excavators that is specifically designed for excavation work in confined spaces such as tunnels, mines, and underground construction sites.
Reduced risk of collision: Tunnel boom arm is designed to work in tight spaces with minimal clearance between the machine and the tunnel walls. The tunnel boom for excavator 's shape and positioning reduce the risk of collision and damage to the machine.
Increased productivity: Tunnel booms enable excavators to work more efficiently and effectively in confined spaces, resulting in increased productivity.
Versatility: Excavator arm for tunneling can be used for a variety of excavation tasks, including digging, grading, and loading. excavator boom for tunneling can also be used in a range of industries, from mining to construction to tunneling.
Tunnel booms are an important tool for excavation work in confined spaces, offering improved safety, productivity, and versatility. excavator tunnel reach allow excavators to work in areas that are difficult or impossible to access with traditional boom configurations, making them a valuable asset in a range of industries.
1. On the same machine, tunnel reach for excavator can obtain greater lifting capacity than the standard arm, the opening angle between boom and arm can reach 180 degrees which can improve 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. Stop valves prevent oil leakage
6. Multi-layer welding of pipe connectors to reduce the risk of oil leakage
7. Cylinder protective cover is beneficial to preventing the cylinder from being damaged in collision
8. Q355B material, using high-quality accessories, full weld, double plate reinforcement in the stress position, etc.
