Detailed Guide to Dismantling the Boom Strip on a Tadano FAUN ATF 80-4 All Terrain Crane

[MikePhua]

Introduction to the Tadano FAUN ATF 80-4 Boom System
The Tadano FAUN ATF 80-4 is a versatile all-terrain crane widely used for lifting operations in construction and industrial settings. A key component is its boom system, which consists of telescopic sections designed for reach and lifting capacity.
Dismantling the boom strip is a delicate maintenance or repair task requiring precision, proper tools, and understanding of the crane’s mechanical and hydraulic systems.
Purpose and Importance of Boom Strip Dismantling
Boom strip dismantling is typically necessary for:

• Inspecting internal components for wear or damage
  
• Replacing damaged boom sections or wear pads
  
• Performing hydraulic cylinder maintenance or seal replacement
  
• Addressing alignment or telescoping issues
  

Proper dismantling procedures ensure safety and prevent further damage to the boom or crane structure.
Key Components of the Tadano FAUN ATF 80-4 Boom

• Telescopic Boom Sections: Multiple nested steel segments that extend and retract hydraulically
  
• Hydraulic Cylinders: Power boom extension and retraction, control angle adjustments
  
• Wear Pads and Guides: Reduce friction between moving boom parts
  
• Boom Hoist and Extension Mechanisms: Winches and cables aiding in positioning
  
• Pins and Bushings: Pivot points and sliding surfaces allowing smooth movement
  

Understanding these parts is critical before attempting dismantling.
Step-by-Step Dismantling Process

• Preparation and Safety Measures
  • Fully support the boom with appropriate lifting devices to prevent accidental movement
    
  • Depressurize hydraulic systems and disconnect power to avoid unexpected cylinder motion
    
  • Wear personal protective equipment (PPE) and follow site safety protocols
    
• Removing External Attachments
  • Detach boom hoist cables, hooks, and external fixtures to access boom joints
    
  • Remove covers or guards protecting the boom strip
    
• Disassembling Pins and Bushings
  • Identify retaining pins securing boom sections
    
  • Use hydraulic or mechanical presses to remove pins carefully without damaging parts
    
  • Inspect bushings for wear and replace if necessary
    
• Extracting Boom Sections
  • Slide out telescopic sections gently, using cranes or gantries to support heavy parts
    
  • Avoid bending or scratching surfaces to maintain structural integrity
    
• Hydraulic Cylinder Detachment
  • Disconnect hydraulic lines from cylinders powering the boom strip
    
  • Remove mounting bolts and carefully extract cylinders for inspection or repair
    
• Cleaning and Inspection
  • Clean all parts thoroughly to remove dirt and debris
    
  • Inspect for cracks, corrosion, or deformation in steel components
    
  • Check wear pads for thickness and replace if worn beyond limits
    

Common Challenges and Solutions During Dismantling

• Stuck Pins or Corroded Bushings: Use penetrating oils and gentle heat to loosen parts without damage
  
• Heavy Boom Sections: Employ suitable lifting equipment and rigging plans to handle safely
  
• Hydraulic Fluid Leakage: Ensure all fluid lines are properly drained and capped before removal
  
• Alignment After Reassembly: Use manufacturer specifications and laser alignment tools to ensure correct fit
  

Maintenance Tips to Prevent Frequent Dismantling

• Regular lubrication of pins, bushings, and sliding surfaces
  
• Scheduled hydraulic system inspections and fluid replacements
  
• Timely replacement of worn wear pads and seals
  
• Monitoring boom extension smoothness and addressing unusual noises promptly
  
• Keeping detailed maintenance logs to anticipate part lifespans
  

Case Story: Efficient Boom Strip Replacement on a Jobsite
A crane operator reported difficulty extending the boom on a Tadano FAUN ATF 80-4 during a large commercial project. Inspection revealed severely worn bushings causing binding.
The maintenance team followed the dismantling procedure, replaced the bushings and wear pads, serviced the hydraulic cylinders, and reassembled the boom strip. The boom functioned smoothly afterward, and the job resumed without significant delay.
Terminology Explained

• Boom Strip: The assembly of telescopic sections and related components that make up the crane boom
  
• Bushings: Cylindrical lining components reducing friction between moving parts
  
• Wear Pads: Protective surfaces that absorb friction to prevent metal-to-metal contact
  
• Hydraulic Cylinder: Device converting hydraulic pressure into linear motion to move boom parts
  
• Telescopic Sections: Boom parts designed to slide within each other for adjustable length
  

Conclusion: Mastering Boom Strip Dismantling for Tadano FAUN ATF 80-4 Longevity
Dismantling the boom strip on the Tadano FAUN ATF 80-4 requires detailed knowledge of the crane’s mechanics, careful planning, and adherence to safety standards. Regular inspections and maintenance minimize the frequency of such extensive procedures.
Following correct dismantling techniques and addressing wear proactively ensure the crane maintains optimal lifting performance and operational safety across its service life.
