Tampo RS-156A Roller Overview and Repair Considerations

[MikePhua]

The Tampo RS-156A roller is a heavy-duty compaction machine primarily used in road construction and large-scale asphalt projects. Renowned for its durability and effective compaction capabilities, the RS-156A model is designed to deliver consistent results while minimizing operator fatigue and maintenance requirements.
Design and Specifications

• Operating Weight: Approximately 14,000 to 15,000 lbs, depending on configuration.
  
• Drum Width: Typically around 7 feet, enabling broad surface coverage in fewer passes.
  
• Operating Length: Approximately 15 to 16 feet, facilitating efficient compaction on wide roads or parking lots.
  
• Drum Type: Smooth steel drums for uniform compaction suitable for asphalt and granular soils.
  
• Vibration System: Equipped with an adjustable vibratory system to optimize compaction for different materials and conditions.
  
• Engine: Reliable diesel engines sized for continuous heavy-duty operation while maintaining fuel efficiency.
  
• Operator Cab: Ergonomically designed for visibility, with basic controls that simplify operation.
  

Maintenance and Repair

• Regular maintenance intervals involve checking hydraulic hoses, drum bearings, and vibration system components for wear or damage.
  
• Monitor engine oil and coolant levels; replace filters as specified in service schedules.
  
• Drum surface must be inspected for cracks or uneven wear that can affect compaction quality.
  
• Vibrator components including eccentric weights and bearings require lubrication and periodic replacement.
  
• Brake systems and transmission components are critical points needing regular inspection for safety and performance.
  
• Repair manuals are essential for detailed guidance on disassembling and servicing pneumatic, hydraulic, electrical, and mechanical subsystems.
  
• Keeping a log of maintenance and repairs aids in troubleshooting and prolongs the roller’s lifespan.
  

Repair Manual Uses

• Step-by-step instructions for removing and replacing major components such as engine, transmission, vibratory motors, and drum assemblies.
  
• Diagrams and parts lists to identify wear items and ordering information.
  
• Safety protocols outlining proper lockout and servicing procedures.
  
• Troubleshooting charts assisting in diagnosing common operational issues.
  

Terminology

• Vibratory System: Mechanism producing vibrations to aid soil or asphalt compaction.
  
• Eccentric Weights: Weights mounted offset on the vibrator shaft creating centrifugal force.
  
• Drum Bearings: Bearings supporting and enabling smooth rotation of the compaction drums.
  
• Lockout Procedures: Safety steps to prevent accidental machine movement during servicing.
  
• Hydraulic Hose: Flexible pipe carrying pressurized fluid in vibration or steering systems.
  

Small Story
During routine service on a Tampo RS-156A roller, operators discovered uneven pavement compaction traced back to damaged eccentric weights in the vibrator assembly. Using the repair manual's detailed procedure, technicians replaced the worn parts and balanced the system, restoring even compaction across the working width. This proactive maintenance reinforced the importance of regular inspection and adherence to service guidelines.
Summary List

• The RS-156A features approx. 14,000 lbs operating weight and 7-foot smooth steel drums.
  
• Adjustable vibratory system maximizes compaction in diverse materials.
  
• Diesel engines deliver robust power with focused fuel efficiency.
  
• Repair manuals guide precise component servicing and safety procedures.
  
• Maintenance focuses on vibration system, drum bearings, hydraulic hoses, and engine health.
  
• Operator-friendly cab design enhances visibility and control.
  
• Regular inspections prevent uneven compaction and unnecessary downtime.
  

The Tampo RS-156A roller exemplifies a reliable compaction solution pairing strong mechanical design with accessible maintenance, ensuring long-term performance on demanding paving jobs.
