RGN vs Lowboy Trailer Guide

Choosing the Right RGN or Lowboy for Heavy Equipment Transport

Heavy equipment transport starts with one basic question: what trailer actually fits the machine and the route? For excavators, dozers, loaders, cranes, industrial machinery, and other large equipment, that decision often leads to RGN and lowboy equipment. The terms are related, but they do not always describe two completely different trailer types.

Buchanan Hauling & Rigging, Inc. provides heavy haul and specialized transportation for construction equipment, machinery, and oversized freight. Its heavy haul equipment lineup includes lowboys, multi axle trailers, and RGN configurations for demanding loads.

RGN and Lowboy Are Related Terms

A lowboy describes a trailer with a low main deck designed to help reduce loaded height. An RGN, or removable gooseneck trailer, describes a design in which the gooseneck can detach from the deck. That lets certain machines drive onto the trailer from the front. Many RGN trailers are also lowboy trailers, so the better question is often which low deck configuration fits the shipment.

This distinction matters when comparing RGN trailer transport and lowboy transport services. A shipper should look beyond the label and confirm the actual trailer design, deck height, deck length, capacity, axle configuration, and loading method.

When an RGN Can Make Sense

RGN freight services are often considered when drivable or tracked equipment can load from the front after the gooseneck is removed. That can be useful for equipment such as:

  • Excavators
  • Bulldozers
  • Wheel loaders
  • Motor graders
  • Certain cranes and industrial machines

The removable neck can reduce dependence on separate loading ramps for compatible machinery. It does not automatically make an RGN the right choice. Equipment dimensions, weight distribution, ground clearance, route conditions, and delivery site access still have to be reviewed.

Why Deck Height Matters

A low deck can be important when the machine itself is tall. Reducing trailer deck height may help control overall loaded height, but the legal and practical result depends on the exact trailer and freight dimensions. Tall equipment can still require permits, route review, or another specialized configuration.

Buchanan's Heavy Haul Permits and Route Planning guide explains why bridges, overhead clearances, road restrictions, and permit requirements can change the transportation plan for oversized freight.

Information to Provide Before Trailer Selection

Before requesting RGN heavy haul or lowboy heavy equipment shipping, provide the carrier with:

  • Exact length, width, height, and operating weight
  • Make and model when available
  • Whether the equipment runs and can drive onto a trailer
  • Ground clearance and any low hanging components
  • Pickup and delivery loading conditions
  • Attachments that ship with the machine
  • Required pickup and delivery dates

Photos can also help the transportation team understand the machine, loading points, and site conditions before dispatch.

Buchanan Heavy Equipment Transport

Buchanan already uses RGN and lowboy equipment within its Heavy Haul Division. Its existing guide, The Right Way to Move Construction Equipment, covers broader planning for excavators, bulldozers, dump trucks, cranes, and similar machinery. This article addresses the narrower question of trailer selection.

For a specific move, Buchanan can review the machine dimensions, weight, loading method, route requirements, and delivery conditions before recommending equipment. If your company needs removable gooseneck trailer transport, lowboy trucking services, or another heavy haul configuration, submit the shipment details through Buchanan's Rate Quote page so the team can evaluate the load and build the transportation plan around the actual equipment.
