The Importance of Proper Excavator Shear Blade Care
Maximizing Excavator Shear Attachment Performance
Regardless of the type of work an excavator shear performs, its cutting blades are its most essential component. With wear over time, blades require regular maintenance to sustain optimal productivity.
Sharpening Schedule
Blades should be professionally sharpened as needed based on the material being cut - for example, demolition shears cutting rebar may only last 40 hours versus wood shearing. Dull blades strain and slow the machine.
Blade Replacement Frequency
Once sharpening no longer restores a cutting edge, it's time for new blades. Reputable manufacturers offer affordable OEM replacements ensuring safe, efficient operation.
Inspect Blade Bolts Regularly
Vibration can loosen excavator shear blade mounting bolts, jeopardizing attachments if they shear. Check and tighten bolts according to the owner's manual to prevent accidents.
Grease Pivot Points Daily
Shear excavator hinges connecting the movable blade halves require daily greasing to protect bearings from dirt and moisture intrusion that causes premature wear.
Clean Debris from Cutting Surfaces
Foreign objects embedded in blade edges accelerate wear and damage. Use a wire brush after shifts to remove any concrete, metal shards, or rocky debris.
Consider Hard-Surfacing Treatments
Options like tungsten carbide overlays on demolition shear blades strengthen alloy steel for maximum penetration of tough materials like asphalt and foundation footings.
Store Out of Harsh Elements
When not in use, store blades with a protective coating in a rainproof area to prevent rust formation between jobs.
Proper care pays off in extended attachment life and maximizes the productivity of every excavator shear.
