Rock grinders and concrete cutter attachments are essential tools for excavators and skid steers. This guide will provide key information on selecting the right attachment for cutting and grinding rock and concrete on your construction site.
These heavy-duty attachments efficiently demolish and remove rock, concrete, and asphalt. Models are available to fit most excavators and skid steers. With advanced hydraulic motor technology and sturdy drum cutter heads, these tools make short work of oversized building materials. Continue reading to learn why rock grinder and concrete cutter attachments are a must-have for demolishing rock and concrete.
What Applications Call for a Rock Grinder Attachment?
Excavator and skid steer attachments that grind rock are ideal for applications where rock removal is necessary. These attachments feature a hydraulic motor that turns a sturdy steel drum lined with carbide teeth or bits at the ideal rotations per minute to fracture rock.
Common applications include:
- Demolishing concrete foundations, walls, and floors
- Removing hardened asphalt
- Cutting trenches through rock for utility lines
- Tunneling through stone
- Accessing ores and minerals in mining
- Eliminating rock obstacles impeding construction
- Creating level building pads and access roads
- Precise slot trenching for utilities and drainage
What Types of Projects Require a Concrete Grinder?
Concrete grinding attachments excel at removing concrete without damaging rebar. These tools smoothly grind concrete surfaces to desired shapes and depths.
Typical concrete grinder attachment applications:
- Grinding high spots and imperfections on concrete floors
- Scarifying concrete for improved bonding of overlays
- Removing deteriorated concrete from bridge decks, parking garages and balconies
- Creating vertical walls and clean corners in concrete
What Features Make Drum Cutter Attachments Effective?
Hydraulically-driven drum cutters dominate the attachment category for rock grinding and concrete removal. The heavy-duty steel body houses a drum lined with exceedingly hard cutters made to fracture the most abrasive materials without fail.
Key features that make drum-style rock and concrete cutter attachments highly effective include:
- Powerful Hydraulic Motors – High torque, hydraulic motors ranging from 40HP to over 100HP provide ample power. Variable displacement motors maintain constant drum speeds even under extreme loads.
- Tuned Rotations Per Minute – Drums turn at the ideal RPMs to fracture rock and concrete through repeated impact blows rather than excessive friction. Faster rotations per minute ensure efficient cutting action across various material types.
- Sturdy Drum Housings – Thick steel drums resist deformation even when pounding through reinforced concrete or granite. The drum’s steel shaft is supported on heavy-duty roller or tapered bearings.
- Carbide Teeth/Bits – Hundreds of inset teeth or bits line the drum circumference, constructed of exceptionally wear-resistant tungsten carbide. The shock and impact tolerated by each tooth is incredible.
How Do I Choose the Right Size Rock Grinder or Concrete Cutter?
These hydraulic attachment tools are available in a range of widths to suit project demands. Consider required cutting depth, width, and machine compatibility when selecting a rock grinding or concrete cutting model.
- Small Drum Cutters – 12″ to 18″ widths for skid steers provide versatility for small demolition jobs. The narrow drum navigates confined spaces.
- Mid-Size Cutters – 20″ to 28″ drums cover most general rock and concrete removal applications.
- Full-Size Cutters – 30″ and larger drums make fast work of substantial concrete structures and rock formations.
- Trenching Wheels – Narrow drums under 12″ wide cut precise trenches through rock or concrete.
- Tunnelling Models – Extra narrow drums with 8″ to 12″ widths provide excellent maneuverability and visibility when boring through rock.
How Do These Attachments Mount to the Base Machine?
Standard excavator couplers accept attachments like breakers, grapples, and brush cutters. Drum-style rock grinding and concrete cutting attachments use the same connections. Models advertised as “Quick Attach” are outfitted for skid steers with universal attachment mounts.
Attachment rotation is powered by hydraulics routed through the boom arm. Controls inside the excavator or skid steer cab govern the attachment. No additional power sources are necessary.
Why are Concrete Grinders a Must-Have Attachment?
As concrete removal attachments, grinders neatly remove layers of concrete without hammering or prying that could damage rebar. These tools leave clean vertical walls and flat floors. Dust is greatly reduced compared to noisy jackhammers that fracture concrete.
Variable speed hydraulic motors mill away concrete using diamonds embedded in the drum surface. Diameters range from 300mm to 800mm or more. Excellent for controlled removal up to 3″ deep.
What Safety Measures Should Operators Observe?
- Wear hearing protection against prolonged noise exposure.
- Ensure hydraulic system pressures won’t exceed attachment ratings.
- Never move loads over people or equipment using excavator attachments.
- Avoid side-loading legs and arms which could overstress components.
- Allow attachments to stop before lifting or repositioning.
- Detach equipment before transport to prevent detachment at high speeds.
