What is the Size of Hydraulic Breaker?

This article explains what is the size of hydraulic breaker for excavator professionals. Choosing the right hydraulic breaker size is vital for efficiency, safety, and equipment longevity. This guide outlines key sizing factors, common industry standards, and expert selection recommendations.

Understanding Hydraulic Breaker Size

  • Definition:
    Hydraulic breaker size typically refers to its operating weight, overall dimensions, and compatibility with host machines.
  • Key Metrics:
    • Operating weight (kg or lbs)
    • Impact energy (Joules or ft-lb)
    • Required hydraulic flow and pressure
    • Tool diameter
    • Carrier weight (excavator or backhoe)

Industry Standard Sizes

  • Mini Excavators (0.5–6 tons):
    • Breaker weight: 60–500 kg
    • Tool diameter: 40–80 mm
  • Midi Excavators (6–12 tons):
    • Breaker weight: 500–1000 kg
    • Tool diameter: 75–100 mm
  • Standard Excavators (12–25 tons):
    • Breaker weight: 1000–2000 kg
    • Tool diameter: 100–135 mm
  • Heavy Excavators (25+ tons):
    • Breaker weight: 2000–7000 kg
    • Tool diameter: 135–210 mm

Important Sizing Considerations

  • Match to Carrier Weight:
    • Breaker should be 8–12% of carrier operating weight, per leading manufacturer guidelines.
  • Hydraulic Compatibility:
    • Breaker must align with the excavator’s hydraulic oil flow and working pressure parameters.
  • Application Demands:
    • Demolition, roadwork, quarrying, or trenching may require different energy capacities.
  • Physical Fit:
    • Ensure breaker dimensions fit the excavator’s mounting and workspace.

Common Selection Mistakes

  • Oversizing:
    • Leads to excessive wear and instability, voided warranties.
  • Undersizing:
    • Causes inadequate breaking performance and low productivity.
  • Ignoring Application Needs:
    • Not assessing rock hardness or site environment can compromise breaker lifespan.

Quick Reference: Hydraulic Breaker Size Table

Carrier Weight (t) Recommended Breaker Weight (kg) Tool Diameter (mm)
1–6 60–500 40–80
6–12 500–1000 75–100
12–25 1000–2000 100–135
25–70 2000–7000 135–210

Expert Sizing Tips

  • Always consult manufacturer compatibility charts for your breaker and excavator models.
  • Use jobsite conditions and productivity targets to fine-tune size selection.
  • Contact reputable suppliers, like Huilian, for personalized technical guidance.
