Golden Rules of Excavator Attachment Maintenance and Application Scenarios Analysis
Release time:
2025-09-24
In the field of construction machinery, the maintenance quality of excavator attachments (such as hydraulic shears, breakers, rippers, etc.) directly determines equipment performance and operational safety. Statistics show that 43% of attachment failures are caused by improper maintenance. This article will provide systematic solutions from three dimensions: daily maintenance, key precautions, and scenario-based applications.
I. Core Maintenance Procedures
- Lubrication Management
Check pin shafts and bearings every 8 hours, using high-temperature lithium-based grease
Breakers require daily injection of special hydraulic oil , clean the oil port before refilling to prevent contamination
- Hydraulic System Maintenance
Regularly test hydraulic oil contamination
When replacing filter elements, inspect hydraulic hoses immediately if cracks or bulges are found
- Structural Inspection
Weekly magnetic particle inspection of attachment welds
Replace ripper teeth when wear exceeds one-third of original size
II. Five Key Precautions
⚠️ Temperature Monitoring
Check cooling system and reduce continuous operation if hydraulic oil temperature exceeds 80°C
⚠️ Compatibility Principle
Breakers must match host machine flow/pressure .
⚠️ Seasonal Adjustments
Use -30°C hydraulic oil in winter, increase oil change frequency in summer
⚠️ Rust Prevention
Apply WD-40 anti-rust coating and wrap pin shafts in moisture-proof film for long-term storage
⚠️ Storage Standards
Store hydraulic attachments vertically to prevent piston rod deformation
III. Scenario-Based Maintenance Strategies
Scenario 1: Mine Crushing Operations
Clean breaker nitrogen chamber dust every 2 hours
Prioritize tungsten carbide hammers, rotate worn surfaces timely
Scenario 2: Municipal Pipeline Construction
Clean shear blades of asphalt residue after daily use
Check seal leaks to prevent soil contamination
Scenario 3: Agricultural Land Preparation
Remove tangled roots before ripper operations
Check bolt torque every 50 hours (450±50N·m)
Conclusion
Proper maintenance can extend attachment lifespan 2-3 times. Establish one-machine-one-file records and customize maintenance plans based on manuals.
