A hydraulic breaker asphalt cutter is a specialized attachment used with hydraulic breakers (also known as rock hammers) mounted on excavators, skid steers, or backhoes. These cutters are designed to efficiently cut or fracture asphalt surfaces rather than pulverize them, offering a more controlled and cleaner breakup for road or trenching work.
- Design: A flat, chisel- or spade-shaped tool that focuses force along a narrow edge, ideal for slicing through asphalt rather than crushing it. Some cutters integrate quick-attach designs for easy swapping with other breaker tools (e.g., moil points or blunt tools).Angled cutting edge is optimized to penetrate and lift asphalt with minimal surrounding damage. Built to match specific breaker sizes and hydraulic specifications (flow, pressure, energy output).
- Applications: Hydraulic breaker asphalt cutter attachments are widely used in:
- Road Maintenance and Repair:Cutting clean edges for patching; Breaking sections for full-depth removal
- Trenching for Utilities:Opening asphalt layers before excavation
- Bridge Deck Removal:Controlled demolition of asphalt overlays
- Airport Runway/Taxiway Work:Precision removal without damaging underlying concrete
- Railway Track Work:Breaking paved sections for track access
- Materials: The cutting blade/tool is typically made from high-strength steel, heat-treated for hardness and impact resistance.
- Configurations:Head: Cross or Parallel; Machine Type: EC40, EC50T, EC60/RX4, EC80, SB52, SB102, SB152, SB202/SBu220, SB302/SB340
