Compact excavators can be transformed into multi-functional machines by switching attachments. Below are the 10 most widely used attachments and their applications:

I. Excavation Attachments

1. Standard Buckets

• Wide bucket (+20% efficiency for loose materials)

• Rock bucket (with manganese steel teeth, 3x longer lifespan)

• Sizes: 0.04–0.3 m³ (matched to excavator weight)

• Applications: Digging, loading trucks

2. Tilt Bucket

• Feature: Hydraulic ±45° rotation

• Advantage: Slope/trend work without repositioning

II. Demolition/Breaking Attachments

3. Hydraulic Breaker

• Impact energy: 5–15 kJ (e.g., 5 kJ for 1.5-ton excavators)

• Frequency: 600–1,200 blows/min

• Requirement: Minimum hydraulic flow ≥20 L/min

4. Hydraulic Shear

• Function: Cuts rebar/steel (30–50-ton force)

• Use: Building demolition, scrap processing

III. Compaction/Finishing Attachments

5. Vibratory Plate Compactor

• Mounting: Quick coupler + hydraulic drive

• Performance: Achieves 95% compaction in trenches

6. Milling Head

• Precision: ±5 mm depth control

• Example: Road patching

IV. Grabbing/Hauling Attachments

7. Hydraulic Thumb/Grab

• Types:

• Orange-peel grab (logs/rocks)

• Clamshell grab (prevents material spillage)

• Opening width: 60–100 cm

8. Rotating Grab

• Feature: 360° continuous rotation

• Use Case: Pipe laying, precise stacking

V. Specialty Attachments

9. Auger (Earth Drill)

• Diameter: 200–600 mm (300 mm for 1.8-ton excavators)

• Max depth: 3–5 m

• Purpose: Tree planting, foundation holes

10. Skeleton Bucket (Screening Bucket)

• Design: Serrated edge + drainage holes

• Efficiency: 40% faster than standard buckets for dredging

VI. Niche but Practical Attachments

• Helical dozer blade: Mud/slope leveling without clogging

• Laser grader: Sub-centimeter precision for farmland

• Stump grinder: Crushes 20 cm stumps in 5 minutes

Attachment Swap Tips

Hydraulic Compatibility

• Ensure attachment pressure ≤ machine rating (typically 20–25 MPa)

• Add a booster pump if flow is insufficient

Quick Coupler System

• Recommended: Euro hitch (compatible with 80% of attachments)

• Swap time: <2 minutes (regularly lubricate pins)

Safety Notes

• Recalibrate relief valves after attachment changes

• Release accumulator pressure before removing breakers
