Trailer Suspension Systems: Get to Tell Apart the Four Main Kinds

Thanks to the internet, there is now a considerable rise in international trade. With this comes the need to transport items from airports and sea harbours to inland locations. As such, one of the most lucrative sectors now is the transport industry. Here, you will invest in a few truck trailers to haul as many bulky goods as possible to maximize your profits.

You can find the ideal trailers at a company dealing with new and used diggers for sale and other heavy machinery. While most people will base their choice of a trailer on its cost and size, it is wiser to base yours on the suspension system. A trailer's suspension system will determine its maintenance needs, stability, and load capacity. It also impacts a driver's safety and comfort when navigating rough terrain.

The following are the four suspension systems you can pick for your truck trailer:

Mechanical system

This system is comprised of reaction arms that will maintain the horizontal orientation of a trailer's axles in all motions. The primary benefit of a mechanical suspension system is thus its stability even in rough terrains. Moreover, with this system, your trailer's load distribution is kept constant even when braking. Mechanical systems are inexpensive, need little to no lubrication, and often have spring mechanisms for the reduction of trailer vibrations.

Air system

This includes inflated rubber and polyurethane bags. It is considered the best replacement for the leaf spring systems used in the past. The leaf spring suspension is no longer recommended for heavy-duty trucks. Air suspension systems allow a comfortable ride and smooth gliding over bumps. The systems also have minimal vibration that translates to reduced wear and tear and maintenance expenses. A few air suspension systems have extra axles that allow the adjusting of a trailer's height. Low height will, for instance, improve vehicle steering, aerodynamics, and stability.

Rigid system

With this conventional option, the movement of one of your trailer's wheels will depend on that of the others. Though not so comfortable for drivers, rigid suspension systems are inexpensive and simple. Their robustness will make them reliable for heavy loads since they will support varied axle movements. The tires will also remain perpendicular to the road when using a rigid suspension system. This generates a secure grip between the tires and the road and reduces the wear of your tires.

Bogie system

This is mostly used in RGN trailers. It allows drivers to lower a trailer's engine position and the centre of gravity. This consequently increases stability and permits the adjustment of a trailer's height. Bogie suspensions are also associated with minimal vibrations and reduced body impact on rough terrains. These boost a driver's comfort.

The selection of a suspension system from the above will be informed by your needed stability level, turning frequency, and the highest expected weight of your cargo. If you choose a suspension that is excessively light for your trailer, it will increase the impact damage to your vehicle. If, on the other hand, the suspension is overly rigid, it contributes to a driver's fatigue.
