In modern European infrastructure development, especially in Spain, construction contractors face increasingly strict requirements for noise control, vibration limitation, and environmental protection. To meet these challenges, a local contractor chose YG Machinery’s excavator milling head (hydraulic drum cutter) for a tunnel and urban rock excavation project, achieving efficient and precise construction results.

Project Background in Spain

The project was located in an urban area in Spain, involving underground utility tunnel excavation and partial rock removal for municipal infrastructure upgrading. The working environment was highly restricted due to:

  • Dense residential buildings nearby
  • Strict noise and vibration regulations
  • Limited working space in narrow streets
  • Hard rock mixed with reinforced concrete layers

Traditional excavation methods could not fully meet the requirements for precision and environmental control.

Customer Challenges

Before choosing YG Machinery, the contractor faced several difficulties:

  • High vibration affecting nearby structures
  • Noise restrictions limiting working hours
  • Inefficient progress in hard rock excavation
  • Need for precise cutting in confined underground spaces
  • High rework rate due to uneven excavation surfaces

The customer urgently needed a solution that could provide controlled, continuous, and low-vibration cutting performance.

Why Excavator Milling Head Was Selected?

After technical consultation, YG Machinery recommended the excavator milling head, also known as: hydraulic milling cutter, drum cutter attachment, excavator drum cutter, milling attachment for excavator.

This equipment was selected because it offers:

  • Continuous rock milling instead of impact breaking
  • Low vibration suitable for urban environments
  • High precision cutting for tunnel profiles
  • Strong adaptability for hard rock and concrete layers
  • Stable performance in confined working conditions

Application Performance in Spain Project

During the project execution, the excavator milling head was used for:

  • Tunnel face excavation
  • Rock surface trimming
  • Concrete structure removal
  • Narrow trench shaping for underground pipelines

Key Results:

✔ Significantly reduced vibration impact on surrounding buildings
✔ Lower noise levels allowed extended working hours within regulations
✔ Improved excavation accuracy and smooth tunnel surface
✔ Reduced secondary finishing work
✔ Faster overall project progress compared to traditional methods

The contractor reported that the milling head provided a much more stable and controlled excavation process, especially in sensitive urban zones.

Equipment Advantages in Real Operation

The excavator milling head demonstrated strong advantages in the Spain project:

  • Continuous cutting ensures consistent excavation quality
  • Precise control improves tunnel shaping accuracy
  • Reduced wear on base excavator compared to impact methods
  • Suitable for complex geological conditions
  • Works efficiently in tight and restricted spaces

It proved to be an ideal solution for modern urban construction requirements in Europe.
