The excavator short arm is a non-standard boom and arm designed specifically for excavators, falling under the category of modifications. The original boom and arm offer a wide working range. However, in confined spaces like tunnels, basements, and narrow operation areas, their maneuverability and loading capacity are limited, significantly hindering construction efficiency and delaying projects. The tunnel boom, a compact version tailored for tunnel crushing and loading, addresses this challenge. It is customized to suit the specific tunnel construction environment. By reducing the size, the overall structural design becomes more suitable for these constrained spaces.
Application area:digging tunnel, subway, digging at narrow place, digging foundation pit, etc
Enlarge Bucket, enlarge and thicken the oil cylinder, and the short boom can be installed with larger breaker.
On the same machine, tunnel arm can obtain greater lifting capacity than the standard arm, that a larger breaker can be used to improve work efficiency
Enlarge cylinders to avoid its damage by excessive vibration
Stop valves prevent oil leakage when replacing breaker by bucket.
Multi-layer welding of pipe connectors to reduce the risk of oil leakage
