Just like any vehicle, regular maintenance is essential to keep your trailers valuable, safe and roadworthy. Not carrying the maintenance of your trailer, especially in the winter season, can result in serious damage for both the driver, the trailer and other users on the road. Therefore, a regular trailer maintenance is the best way to protect your fleet, especially in winter.
We have listed below the recommendation for a minimum trailer maintenance a fleet owner should do, to ensure your vehicle is safe and will perform better and last longer. However, depending on the trailer type, size and usage (including mileage and cargo weight), your trailer could potentially need more maintenance checks on the different components than the below checklist.
First and foremost, make sure all your trailer lights are working properly, whatever your trailer type is. During winter, days are shorter and darker: for this reason, it is vitally important to check all lighting:
Finally, check if the registration plate and the reflectors visibility are clearly illuminated.
Worn tyres reduce starting traction by 30% to 50%: it is good practice to ensure your tyre treads depth do not get below 3mm.
Worn tyres can also burst on the road, especially at high speeds. Therefore, it is crucial to check your tyres’ life expectancy, and watch for these two wear signs:
Ensuring good tyre pressure is crucial to ensure safe and reliable operation, while reducing fuel consumption. Each manufacturer has its own specifications: they are either indicated on the tyre’s sidewall, in your trailer’s owner manual or on the tyre manufacturer’s website. The tyre pressure is either rated in PSI or pounds per square inch.
Tyre pressure must be checked a few hours after parking the trailer, to get an accurate reading and rating. Most common tyres need to be pressured to at least 8.5 Bar. Please note that low pressure can result in blowouts. Also, if you are travelling to the Nordics or in a snow area, check for mandatory regulations on mud + snow tyres.
To further save costs and reduce vehicle downtime, you can install a tyre pressure monitoring solution for trailers (TPMS). It helps maintain tyre pressure, detecting slow punctures early, maximizing tyre life and allowing tyres to be repaired rather than be replaced.
Check your brake operations and brake air pipes. When the weather gets colder, the brake connections and airlines can freeze or split due to the condensed water in the brake system. This in turn can lead to two major issues:
Therefore, it is highly recommended to check the sealing rubbers of the coupling hands at regular intervals for leaks. We advise you to always have a spare in the trailer: the yellow and red and the air coils.
Finally, the air tank of the trailer should be checked regularly for condensation, which can easily be removed via the drain valves of the air tank underneath.
Finally, the last maintenance check is your trailer body:
More generally, we advise you to regularly wash and clean your trailer. There might be dirt on your body, on your chassis or on your roof, especially in autumn and winter when driving on dirt roads.
Make sure all the above components are compliant with MOT. Some of these checks require specific tools, knowledge, and skills. If you can’t unsure how to maintain them, you can outsource your trailer maintenance to an experienced and reliable third party.
