Our Range of Dolly Trailers for Sale

So, why do you need a dolly trailer? A dolly trailer is an attachment used to connect and tow additional trailers, increasing hauling capacity. It has its own axle set, drawbar, and coupling system, which allows multiple trailers to be pulled safely. Our range of dolly trailers provide flexibility in freight and machinery transport, especially for long-distance or high-volume loads.

  • The Single-Axle Dolly Trailer: Compact and manoeuvrable, this trailer is ideal for lighter loads or short-haul operations where space and turning radius are important.
  • The Tandem Gooseneck Dolly: This trailer features a gooseneck design for improved stability and weight distribution. The tandem axles provide strong load capacity, ideal for heavy machinery or oversized freight transport.
  • Tri Dolly: A trailer that’s equipped with three axles for maximum weight support and stability. It’s designed to handle extremely heavy loads safely, and is often used in mining, construction, or industrial haulage applications.

Tandem vs. Tri-Axle Dolly: What’s the Difference?

The key difference between tandem and tri-axle dolly trailers lies in axle configuration, load capacity, stability, and manoeuvrability. A tandem dolly is equipped with two axles, suitable for medium to heavy loads. 

It offers good stability while remaining relatively manoeuvrable and is easier to handle in tighter spaces. It’s lighter in weight meaning operating costs can be lower compared to larger models.

In contrast, the tri-axle dolly trailer features three axles, providing a significantly higher weight capacity and improved stability when carrying extremely heavy or oversized loads. 

These added features reduce the strain on roads and equipment and are ideal for extreme haulage in industries like mining, heavy construction, or oversized freight transport. However, its longer wheelbase can reduce manoeuvrability in confined areas.

Key Features and Specifications to Consider

Searching for a dolly trailer for sale is not simply selecting one that looks the part. It is important to focus on performance capabilities and build quality to ensure it meets your hauling requirements. Key things that are necessary to consider are:

  • Axle Configuration: Single, tandem, or tri-axle, depending on the load capacity and stability needed.
  • Load Capacity: The maximum weight the dolly can legally and safely carry.
  • Braking System: Air or electric brakes for reliable stopping power under load.
  • Coupling Type: Turntable, fifth wheel, or gooseneck connection for compatibility with your prime mover and trailers.
  • Chassis Construction: Heavy-duty steel frame for strength and durability.
  • Suspension System: Mechanical or air suspension for smoother rides and reduced cargo stress.
  • Tyres and Wheels: Quality, load-rated tyres suitable for road and terrain conditions.
  • Safety Features: Lighting, reflectors, and load-securing points in compliance with regulations.
  • Finish/Coating: Corrosion-resistant paint or galvanising for extended lifespan.

The Benefits of a Low Loader Dolly

A low loader dolly offers significant advantages for transporting heavy, oversized, or tall equipment. Constructed with robust materials and precision engineering, it can handle heavy loads while maintaining stability and control, reducing the risk of accidents or equipment damage. 

Its design lowers the overall deck height, allowing for increased load clearance under bridges and power lines while improving stability during transport. Built for strength and reliability, it’s an ideal choice for demanding heavy-haul applications, offering a number of benefits:

  • Lower deck height for improved load clearance under bridges and power lines.
  • Enhanced stability during heavy or oversized equipment transport.
  • Easier and safer loading and unloading of machinery.
  • Ideal for tall loads that exceed standard trailer height limits.
  • Even weight distribution reduces strain on prime mover and trailer.
  • Minimises axle wear and extends tyre life.
  • Improves fuel efficiency by optimising load balance.
  • Designed for heavy-duty performance in demanding haulage conditions.
  • Suitable for construction, mining, and industrial transport applications.
