Businesses can only succeed when they are in constant motion, and many agricultural firms rely on their trailers in order to transport goods and perform a range of tasks on and off the land.
Not only does this mean that you need to pick the right high-quality trailer for the needs of your business, but you also need to make arrangements to ensure it is professionally serviced and repaired.
We can provide that complete service, offering tailored advice to ensure you get the right equipment customised to meet your exacting needs, whilst also offering maintenance and servicing to ensure it lasts as long as possible.
The biggest reason why this is so important is that driving an unsafe trailer is against the law, but the reason why the Highway Code is particularly strict is that an unsafe vehicle has the potential to cause serious accidents on the road.
Whilst anything that is a cause for concern should be checked, here are some of the most common causes of trailer accidents, and how a regular maintenance routine can help avoid them.
Brake Fade
Worn and faded brakes are a potential danger with any vehicle, but brake fade can be particularly problematic and difficult to diagnose with trailers, as a loaded trailer can lead to unexpected braking properties and longer stopping distances.
Brake fade can cause accidents for a range of reasons, not only due to brake failure, but also due to poor brake alignment or synchronisation between the towing vehicle and trailer. These issues can lead to a loss of control, which can increase the risk of a collision or crash.
Effective maintenance will not only replace brake pads and shoes, but also examine particular wear trends to ensure that the brakes are functioning evenly and thus will be balanced and consistent in an emergency braking situation.
Decoupling
A potentially particularly dangerous accident, if the trailer is not hitched correctly to the towbar of the towing vehicle or there is a problem with the attaching equipment, it could potentially lead to the trailer detaching. If this happens whilst on the road, the unpredictability of the trailer could cause a collision with other vehicles on other lanes.
There are multiple failsafe systems in place to ensure that the trailer stays attached, and frequent inspections of the mechanics will help to minimise the risk of a failure of the coupling system.
Poor Visibility
The lights on the back of a trailer are linked to the towing vehicle and are even more critical than they are on a standard car.
A lot of accidents are caused by poor visibility, as the car behind cannot properly see where the trailer is in relation to the rest of the vehicle and thus cannot adequately anticipate where it is moving on the road.
Checking to make sure all of the lights work, including the tail lights, brake lights, turning indicators and hazard warning lights, all work and work quickly.
As well as this, make sure that the reflectors are in good condition, are undamaged and remain clean. They are an easy and vital way for cars to see the trailer and where it is on the road.
Snaking And Jackknifing
A common cause of trailer accidents that is typically associated with the trailer itself is swerving and snaking, which is where the trailer begins to oscillate behind the towing vehicle.
A degree of snaking can happen for several reasons, particularly in situations where a car is dealing with strong winds, high speeds and the effects of aerodynamic wake, but excessive levels of snaking are not only a serious hazard but could be the result of a mechanical issue.
At worst, it can cause a jackknife, a serious incident where a trailer whips around the towing vehicle, often causing a significant loss of control and the potential for serious accidents.
All of these issues can make a car and trailer more difficult to control at high speeds, whilst driving straight ahead and whilst turning.
They are caused in part by imbalances with the trailers’ braking and suspension. This can be detected through wheel balancing and inspections of the wheels and springs. They can also be the result of damage or rough terrain that affects the wheel, suspension or chassis.
Drivers can also help to minimise the risk by evenly distributing loads and gently slowing down to regain control of a snaking trailer rather than locking up the brakes or turning sharply. It also helps to take some time to get accustomed to how the trailer feels both empty and with a typical load.
