Egli CMS Excavator Saw Attachment

Precise Cutting for Rail Maintenance and Infrastructure Projects

CMS excavator saws are designed for excavators working in rail, civil construction, and structural cutting applications, providing a controlled solution for cutting concrete, reinforced concrete, steel, brick, and rock. With the ability to cut vertically, horizontally, and diagonally, they allow operators to perform precise cuts directly on site, reducing manual work and improving overall efficiency.


By enabling accurate, controlled cutting with minimal rework, excavator saws help reduce labour time, improve safety, and increase productivity on site.

Unlike hydraulic breakers, CMS excavator saws provide low-vibration, controlled cutting, reducing the risk of damage to surrounding infrastructure.

Key Features and Advantages

Helps crews complete cutting work faster with consistent, high-quality results:

  • Cuts concrete, reinforced concrete, steel, brick, and rock
  • Vertical, horizontal, and diagonal cutting capability
  • Flush cutting on floors, walls, and ceilings
  • Automatic speed regulation and monitoring
  • Overload protection for saw blade
  • Adjustable cutting force based on material
  • Optimal water cooling system (centre-fed, both sides)
  • Angle display in two axes for precise control

Applications


CMS excavator saws are widely used in rail maintenance and infrastructure projects, where precise, controlled cutting is required without damaging surrounding assets.


  • Rail infrastructure cutting and modification - cutting concrete, reinforced structures, and rock for upgrades and installation work
  • Precision demolition in rail environments – controlled cutting of walls, slabs, and structures in tunnels and confined spaces
  • Trenching and cable installation – cutting concrete, asphalt, and rock for rail-side services and utilities
  • Low-vibration cutting near sensitive assets – reducing risk to surrounding infrastructure compared to hydraulic breakers

  • Why not a hydraulic breaker?

    CMS excavator saws provide a controlled alternative to hydraulic breakers, particularly in rail and infrastructure environments where precision and asset protection are critical.


    • Low vibration cutting reduces the risk of damage to surrounding structures
    • Controlled, precise cuts minimise overbreak and improve accuracy
    • Cleaner results reduce the need for rework and secondary processing
    • Improved safety by reducing uncontrolled material movement

    Unlike breakers, excavator saws allow operators to cut exactly where needed, making them ideal for work near sensitive infrastructure, tunnels, and confined environments.

  • How the CMS excavator saw works

    CMS excavator saws are designed to deliver consistent cutting performance across a wide range of materials and conditions.


    • A control system provides real-time feedback on cutting angle and depth, allowing precise operation
    • Automatic speed regulation and monitoring ensures optimal performance during cutting
    • Adjustable cutting force allows the operator to match performance to the material
    • An integrated system delivers optimal water cooling from the centre of the blade on both sides, helping maintain performance and extend blade life

    Together, these systems allow stable, efficient cutting with minimal interruption during operation.
