General Trailer Servicing

Why It Matters and What It Involves

Small trailers, such as utility trailers, fridge trailers, horse box trailers, and boat trailers, are often taken for granted. They’re simple and usually reliable, which is exactly why regular servicing is easy to overlook. However, routine maintenance is essential for safety, longevity, and trouble-free towing. A well-maintained trailer not only protects your cargo but also prevents breakdowns and costly repairs down the road.

Why Regular Trailer Servicing Is Important

Unlike vehicles, trailers don’t have engines to signal problems early. Issues often go unnoticed until something fails on the road or during a heavy load. Regular servicing helps identify wear and tear early, keeps the trailer road-legal, and ensures safe operation. It also extends the lifespan of key components such as bearings, tyres, brakes, and suspension.

What To Look Out For

Wheel Bearings

Wheel bearings are one of the most critical components on any trailer. They should be cleaned, inspected, and re-greased regularly. Worn or dry bearings can overheat and seize, potentially causing wheel loss. For boat trailers, bearing maintenance is especially important due to water exposure.

Tyres and Wheels

Trailer tyres should be checked for tread depth, cracking, uneven wear, and correct pressure. Underinflated or aged tyres are a common cause of blowouts. Don’t forget to inspect wheel nuts and the spare tyre as part of routine servicing.

Brakes (If Fitted)

Braked trailers require periodic inspection of brake pads, shoes, cables, drums, or discs. Brake adjustment ensures even stopping and prevents premature wear. Hydraulic or electric brake systems should also be checked for leaks, corrosion, or faulty wiring.

Lights and Wiring

Faulty trailer lights are both dangerous and illegal. Servicing includes checking indicators, brake lights, taillights, and number plate lights, as well as inspecting wiring for damage or corrosion. A clean plug connection ensures reliable electrical performance.

Suspension and Axles

Springs, shackles, bushes, and axles should be checked for cracks, sagging, or excessive wear. A failing suspension system can affect handling, tyre wear, and load stability.

Coupling and Safety Chains

The tow coupling must be secure, correctly adjusted, and free from excessive wear. Safety chains should be properly rated, undamaged, and securely attached. These components are vital for safe towing and legal compliance.

How Often Should a Trailer Be Serviced?

For most small trailers, a general service is recommended at least once a year or every 10,000 miles whichever comes first. Trailers used frequently, under heavy loads, or in harsh environments (such as saltwater use) may require more frequent.

Fridge and Freezer Trailer Servicing

Fridge and freezer trailers are the backbone of temperature-controlled logistics, ensuring that perishable goods reach their destination in perfect condition. For businesses that rely on consistent refrigeration performance, keeping trailers in optimal working order is essential.

The Importance of Regular Fridge Trailer Servicing

Routine servicing is the first line of defence against costly breakdowns and product loss. Refrigeration units operate under demanding conditions, often running continuously for long periods. Over time, wear and tear can reduce efficiency and lead to unexpected failures.

A professional service typically includes:

Inspection of refrigeration units and compressors
Checking refrigerant levels and detecting leaks
Testing electrical systems and control panels
Cleaning condensers and evaporators
Assessing door seals and insulation integrity

By scheduling regular maintenance, operators can reduce downtime, improve fuel efficiency, and ensure compliance with food safety and transport regulations.

Fridge unit removal and refit

Removing and Fitting Govi Monoblock Fridge Units on Fridge Trailers

Govi Monoblock Refrigeration Units are widely used on fridge and freezer trailers due to their compact design, reliability, and ease of installation. Correct removal and refitting is essential to maintain performance, ensure food safety, and avoid damage to both the unit and the trailer structure.

Preparation and Safety

Before any work begins, the trailer will be parked on level ground with the electrical supply isolated. The unit will then be disconnected from mains or generator power and confirm that no live circuits remain. Caution must be taken as monoblock units are heavy and awkward to handle. We will always check the unit’s data plate and installation manual, as Govi models vary in weight, fixing method, and electrical requirements.

Removing the Monoblock Unit

Removal starts from inside the trailer. The internal evaporator section is typically secured with silicone around the cut-out panel. The silicone will be cut evenly to prevent distortion of the wall panel.
