Understanding The Versatility of Tri-Axle Semi Trailers

Semi-trailers offer great versatility for transporting goods and a tri-axle trailer will add to that versatility. But you will only achieve maximum versatility if you understand what such a trailer is and what it can do for you.

What is a Tri Axle Semi Trailer?

A tri-axle trailer, as the name suggests, is a trailer with three axles. These are all grouped at the rear of the trailer and allow a more even distribution of weight and increased loads.

Other trailer types have different combinations of axles, including quad-axle trailers. Tri axles, however, are smaller, lighter and cheaper by comparison and can be more easily manoeuvred in tight spaces.

Benefits of Using Tri-Axle Semi Trailers

Compared to semi-trailers with two axles, a tri-axle version offers several benefits:

• The additional axle means the weight is distributed more evenly and enables the trailer to have greater carrying capacity, so it is more suitable for heavy loads.
• Because the cargo is distributed more evenly over the three axles, it provides a more stable ride. This is particularly important when carrying heavy loads and travelling at speed over uneven surfaces.
• Three axles allow a greater legal capacity so there is less likelihood of breaching weight restriction regulations.
• The better distribution of loads means there is less strain on each axle, reducing wear and extending the life of tyres as well as the axles.
• Operating costs should be reduced and efficiency increased since the additional load capacity will result in fewer trips being necessary. This will reduce fuel, labour and maintenance costs.
• In many configurations, one of the axles will be a non-driving axle that can be lifted from the road when no load is being carried. This will further reduce tyre wear.

Best Uses for Tri-Axle Trailers

Due to the three axles spreading loads better, reducing strain and improving stability, tri-axle trailers are ideal for carrying heavy loads. They are commonly used, therefore, in the construction industry to haul heavy pieces of equipment such as excavators and cranes. They are also popular throughout the logistics and transport industry to carry large containers and other heavy loads where carrying capacity and stability are of high importance.

A customised tri-axle trailer is particularly versatile because it can carry loads that are especially wide or long. Fitting bespoke suspension and braking systems will also add to safety and stability.

Maintenance & Longevity Tips

Proper care and maintenance of your tri-axle trailer will ensure it gives long service without costly repairs. The trailer is as important as the truck that pulls it so always adhere to the service manual for both. A service is typically required at six-monthly intervals for non-steered trailers and more frequently for steered versions, especially if carrying heavy loads regularly over long distances.

In between services, check the trailer frequently, particularly before and after trips:

• Check the tyres for wear and damage and ensure the air pressure is correct. Uneven tyre wear may indicate incorrect axle alignment while properly inflated tyres will reduce wear and improve fuel efficiency.
• Brakes should be responsive and not show signs of corrosion or damage.
• Ensure that lubricants are of the correct grade and are at the required levels, with no leaks, and that components are properly greased.
• All lighting and electrical systems need to be working correctly with functioning connections between the truck and the trailer.

If there are any problems, get them sorted promptly, by a professional if necessary. Correct maintenance will ensure your trailer operates properly, safely and reliably.
