American 35A Loader Track System Overview

[MikePhua]

The American 35A is a heavy-duty tracked loader known for rugged construction and reliable performance across challenging terrain. Its track system is a vital component enabling steady mobility, traction, and operational efficiency.
Track System Specifications

• The track gauge can be adjusted from a narrow 8 feet to a wide stance of approximately 10 feet center-to-center.
  
• It features a patented Twin-Section track design, which includes narrow flanges enhancing durability and reducing ground pressure.
  
• Tracks are constructed with robust materials suitable for heavy loads and harsh environments.
  
• Track rollers utilize high-density polyurethane or rubber materials with sealed bearings for longevity and smooth operation.
  
• The drive sprockets are elevated with low-friction, replaceable sprocket rollers to reduce wear and facilitate maintenance.
  

Hydraulic and Control Features

• The hydraulic system powering the tracks is pressurized to reduce cavitation, improving response and control.
  
• Power-assisted servo controls improve operator precision and reduce fatigue.
  
• The loader includes advanced track suspensions with independent torsion axles providing superior ground contact and smoother rides.
  

Technical Terms Explained

• Track Gauge: The distance between the centerlines of the two tracks.
  
• Twin-Section Track: A track design with two interlocking sections to improve strength and flexibility.
  
• Drive Sprocket: The toothed wheel transferring engine power to the tracks.
  
• Cavitation: Formation of vapor bubbles in hydraulic fluid causing performance issues.
  
• Servo Control: A feedback system providing precise control of mechanical components.
  

Operational Benefits

• Variable track width allows the loader to adapt to different site constraints and terrain types.
  
• Durable track materials and design reduce downtime caused by track failures.
  
• Hydraulic system innovations improve traction, reduce wear, and allow for smoother, more efficient operation.
  

Maintenance Tips

• Regular inspection and lubrication of track rollers and sprockets prolong service life.
  
• Maintaining proper tension of tracks prevents premature wear.
  
• Hydraulic system maintenance including fluid and filter changes prevents cavitation-related damage.
  

Summary
The American 35A loader’s advanced track system with adjustable gauge, twin-section tracks, and pressurized hydraulic controls delivers durable, adaptable performance for diverse construction and loading tasks. Proper maintenance combined with its rugged design ensures sustained mobility, operator comfort, and machine efficiency in demanding working conditions.
