What Kind of Trailer Is Required for Moving a House: A Comprehensive Guide

[MikePhua]

Introduction to House Moving Trailers
Moving an entire house is a complex operation requiring specialized equipment, particularly trailers designed to safely transport large and heavy structures. The type of trailer needed depends on the size, weight, and structure of the house, as well as road and legal regulations. Choosing the right trailer is critical to ensuring the move proceeds safely and efficiently.
Types of Trailers Used for House Moving

• Dollies
  • Small trailers placed under the house’s corners or load points
    
  • Equipped with wheels and sometimes hydraulic jacks for leveling and lifting
    
• Multi-Axle Flatbed Trailers
  • Heavy-duty trailers with multiple axles to distribute weight evenly
    
  • Often custom-built to match the width and length of the house
    
• Lowboy Trailers
  • Low ground clearance trailers that facilitate moving tall structures under bridges
    
  • Designed for heavy and oversized loads
    
• Self-Propelled Modular Transporters (SPMTs)
  • Highly maneuverable platforms with many wheels, used for very large or complex moves
    
  • Can be controlled precisely and distribute extreme weights
    
• Beam Trailers
  • Used for supporting beams of a house during transport
    
  • Typically used in combination with dollies or other trailers
    

Terminology Clarified

• Axle: A central shaft for rotating wheels, multiple axles help distribute heavy loads
  
• Load Distribution: The way weight is spread across a trailer to avoid overloading any single point
  
• Hydraulic Jacks: Devices that raise or lower the house or trailer for leveling and adjustment
  
• Oversize Load: A load exceeding standard legal size or weight limits requiring special permits
  

Factors Affecting Trailer Choice

• House Size and Weight
  • Larger or heavier houses require trailers with more axles and higher weight capacity
    
• Route Constraints
  • Bridge heights, road widths, and turns influence trailer height and maneuverability needs
    
• Local Regulations
  • Permit requirements, escort vehicles, and allowable load dimensions vary by jurisdiction
    
• Ground Conditions at Pickup and Delivery Sites
  • Trailers must be compatible with access roads and terrain
    

Case Study: Moving a Two-Story House Using Multi-Axle Trailer
A historic two-story house was relocated across a city using a custom multi-axle flatbed trailer. The trailer’s design ensured even weight distribution, and hydraulic jacks maintained level during transport. Coordination with city authorities and route planning allowed a smooth move with minimal disruption.
Case Study: Using SPMTs for Large Modular Homes
For moving a very large modular home, SPMTs were employed due to their ability to handle heavy loads with precise control. This approach enabled the home to be transported through tight turns and uneven terrain without damage.
Additional Considerations

• Hire experienced professional movers specializing in house transport
  
• Ensure thorough route surveys to identify obstacles and required permits
  
• Factor in setup time for house lifting and securing on trailers
  
• Use appropriate tie-downs and supports to prevent shifting during transit
  

Anecdote: The Challenge of Moving a Historic House
During a house move in a small town, unforeseen overhead wires and narrow streets required last-minute adjustments to trailer height and route. The team had to temporarily remove street signs and coordinate with utility companies, illustrating the importance of flexibility and planning.
Conclusion
Selecting the appropriate trailer for moving a house depends on multiple factors including size, weight, route, and legal regulations. Options range from dollies and multi-axle flatbeds to advanced SPMTs. Proper planning, expert handling, and suitable equipment ensure the house move is safe, efficient, and preserves the structure’s integrity.
