DESCRIPTION

The RockZone Rockwheel Drum Cutter Attachments are built for tough, heavy-duty tasks like rock excavation, concrete grinding, trenching, and demolition. Available in three powerful model G50, G60, and G125 these drum cutters offer exceptional versatility, performance, and durability for 40-150 ton excavators. Engineered to handle hard materials such as rock, reinforced concrete, and asphalt, each model provides a range of cutting capabilities, from high-precision trenching to large-scale rock removal.

  • G50 Model (190hp, 40-60 Ton Excavators): A high-torque, 41" wide drum cutter designed for efficient rock and concrete removal, ideal for medium to large projects.
  • G60 Model (300hp, 50-70 Ton Excavators): A more powerful cutter for heavy-duty applications, offering a 41" width and superior torque for tougher tasks.
  • G125 Model (536hp, 75-150 Ton Excavators): The most powerful option, with a 59" cutting width and unmatched cutting force, perfect for large-scale excavation, mining, and tunneling.

Each model uses a low-vibration, low-noise design to minimize disruption in sensitive environments, making them ideal for both construction and demolition projects in urban or noise-sensitive areas. Built with robust drums, efficient hydraulic motors, and optimized gear ratios, the Rockwheel attachments provide high precision, reliability, and long-lasting performance, ultimately reducing operational costs.
