How long do semi-trailers last?

Every piece of machinery and hardware has a lifespan, but whether they last long or not is largely dependent on how they are used and maintained.

Trailers and semi-trailers are designed specifically to last – they need to endure harsh and changing weather conditions, varying load types, and consistent
wear and tear. But even these robust products can only withstand so much before their performance becomes compromised.

Buying a second-hand trailer can still be worth it. Let's take a look at the important elements to consider.

Maintenance

How long do semi-trailers last? Well, it has a lot to do with how well they are maintained. While the calibre of parts plays an important role, the overall
upkeep and maintenance of a semi-trailer are what will ensure its longevity. For example, there is no point in purchasing new brake pads if your axles are
in bad shape.

The lifespan of a semitrailer can be significantly extended if it undergoes a robust maintenance plan. Regular inspections will ensure minor scratches are
dealt with and don’t lead to rust or corrosion, for example. Regular maintenance ensures small issues don’t become large, costly ones down the road that
reduce the lifespan of a trailer.

When looking to buy a second-hand semi-trailer, be sure to inspect the maintenance reports to see how often it has been serviced and the quality of new
parts that have been used.

Function

Should you buy a 10-year-old trailer?  This depends on the trailer’s function. The longevity of a semi-trailer is largely determined by how it is used. A
curtainsider hauling heavy machinery will take on more damage over time than a reefer carrying lightweight products.

Trailers that are used for long hauls across borders will also incur more wear and tear than ones that are only used for shorter trips in urban environments.
Therefore, the function of the semi-trailer plays an important role in how long it will be able to perform at an optimal standard.

Brand

The manufacturer also plays a role in a semi-trailer’s lifespan. As with all hardware products, the quality of the overall manufacturing and its parts will
ensure its longevity. Reputable brands such as Krone, Schmitz, and SDC are leaders in semi-trailer manufacturing and so any of their products will deliver
quality and performance for longer than other brands.

However, there is a consideration to take into account – maintenance and upkeep. The significance of a logo is not enough if a trailer is poorly maintained.
A well-maintained semi-trailer from a middleweight brand will last longer than a poorly maintained one from a reputable brand.

Type

Is buying an older trailer worth it? This depends on the type of trailer you are looking for and your business requirements. Each trailer type has a different
lifespan. This is largely due to the different functions they perform and the cargo they carry.

Curtainsiders usually undergo more wear and tear than other trailers due to the various types of cargo that they commonly haul. The tarpaulin fabric
requires regular maintenance and the axles need consistent checkups to keep it performing optimally. Refers have more components to maintain, such as
the cooling and electrical systems, which increases the number of parts to upkeep.

How to make your semi-trailer last longer

The longevity of your semi-trailer is largely up to how you use and maintain it. Here are a few tips you can use to ensure your semi-trailer enjoys a longer lifespan.

• Tires

Check for any damage or wear and tear regularly. Also, it is important to monitor your tires’ air pressure.

• Brakes

Ensure that the brakes are responsive by tightly sealing the gladhands. Check the condition of your tire drums to ensure they are working correctly.

• Lubricants and fluids

Make sure all the necessary fluid levels are consistently topped up, especially oils. Inspect the undercarriage of the trailer for any leaks and cracks,
especially in refrigerated trailers.

• Electrical

Make sure all the lights and indicators are working before embarking on a haul. Remember to clean the lenses. Check all the electrical wiring for damages
and repair where needed.

• Pneumatic system

Pneumatic fittings require regular maintenance, so ensure to visually inspect them as often as possible.

• Suspension

Look for signs of heat cracks on the air springs, tears, and irregular wear. Make sure the air springs have enough pressure and are equal throughout.

• Keep it clean

Regular cleaning helps combat corrosion. If left unclean for some time, vital components of your trailer could become faulty and impact its performance.

Following these simple steps will ensure your sem-trailer last longer.
