4 Types of Heavy Haul Trailers

Heavy hauling has always been an important aspect in the trucking industry. Heavy-duty trailers are ideal when transporting oversized, overweight, tall or wide loads.

What is a heavy haul trailer?

Heavy-duty trailers are usually classified by the number of axles, and the more axles, the greater the capacity. The number of axles of common heavy-duty trailers is usually more than 5, and can reach up to 19 axles.

Heavy-duty trailers can typically transport the following loads:

  • Turbines
  • Homes
  • Agricultural equipment
  • Cranes
  • Timber
  • Boilers
  • Excavators
  • Piping
  • Planes
  • Wind energy equipment
  • Boats
  • Mining Equipment

But to safely and successfully transport oversized cargo, legal considerations are essential. And this factor varies from state to state and in other local jurisdictions. But oversized permits are necessary, and route planning is critical to preventing space and technical challenges that could limit transportation.

In addition to paying attention to the size, it is also necessary to pay attention to the weight limit of the bridge, so as to avoid the bridge being broken due to the excessive weight when passing the bridge.

4 types of equipment transport trailer

When transporting large cargo, there are usually the following options:

  • Extendable flatbed trailer
  • RGN trailer
  • Step Deck Trailer
  • Extendable double decker trailer

1. Extendable flatbed trailer

A flatbed semi-trailer is one of the most common trailers on the road because it can carry a variety of cargo. Extendable flatbed trailers are especially important when the cargo is large and cannot be carried by standard flatbed semi-trailers. Because it can hold longer loads such as wood or pipes.

Standard flatbed semi-trailers are usually 40 feet long, but extendable flatbeds can be up to 79 feet long.

2. RGN trailer

Removable gooseneck trailers are ideal for transporting large equipment. Because there is a ramp at the front of the gooseneck, it is beneficial to drive the equipment directly onto the trailer.

It can also be divided into standard RGN trailer and extensible RGN trailer. Extendable RGN trailers are also used for extra-long and heavy loads. Such trailers usually have a large number of axles to accommodate heavier loads.

3. Step Deck Trailer

Step-deck trailers can also be floor-mounted trailers and can transport some tall and medium loads that might otherwise exceed state height regulations. The advantage of having a two-height deck is that smaller cargo can be placed on the upper deck, and taller and larger cargo can be placed on the lower deck.

4. Extendable double deck trailer

Some shipments may exceed the legal height of 8 feet 6 inches. When you want to transport this type of cargo, you need to use the drop deck, which can legally transport cargo up to 12 feet.

Extendable double deck trailers have an elongated well that can accommodate longer, taller loads. Likewise, the more axles there are, the greater the weight that can be carried.
