Heavy-duty trucks, trailers, and plant equipment are long-term investments and, like any asset, they need consistent care to deliver lasting value. In industries like construction, mining, logistics, and agriculture, where machinery is exposed to tough terrain, demanding workloads, and extreme conditions, regular maintenance is not optional; it’s essential.

At PR Group, we’ve seen it all: trucks that run smoothly for over a decade, and others that fail after just a few years, all because of one key difference: maintenance habits.

This guide explains why regular maintenance matters, what it involves, and how it protects your equipment, your workforce, and your bottom line.

Why Maintenance Should Be a Core Part of Your Operation

1. Maximise Equipment Lifespan

Routine servicing reduces component wear and prevents premature failure. Proper lubrication, fluid changes, and cleaning can extend the working life of:

Truck engines and transmissions
Hydraulic systems in tippers and trailers
Undercarriages and track systems in plant equipment

With scheduled maintenance, a used truck can remain operational and profitable for years, often well past the 1-million km mark.

2. Reduce Unexpected Downtime

Breakdowns don’t just cost money; they disrupt schedules, strain staff, and frustrate clients. By detecting issues early, you avoid on-site failures and roadside emergencies.

3. Improve Fuel Efficiency

Simple maintenance tasks like replacing air filters, checking tyre pressure, and tuning engines have a direct impact on fuel consumption. Well-maintained vehicles burn less diesel, which adds up over thousands of kilometres.

What Regular Maintenance Should Include

A good maintenance programme covers preventative, predictive, and corrective practices. Whether you’re managing trucks, trailers, or yellow plants, the essentials remain consistent:

Daily/Pre-Use Checks

Tyre condition and inflation
Fluid levels (oil, coolant, brake fluid)
Visual inspection for leaks or damage
Lights, indicators, and warning systems
Proper load securing and brake testing

Weekly/Monthly Tasks

Grease fittings and joints
Clean filters and vents
Check and top up hydraulic systems
Inspect brakes, suspension, and undercarriage components
Verify all fasteners and mounting points

Scheduled Servicing (per OEM recommendation)

Engine oil and filter change
Gearbox and diff inspection
Air, fuel, and hydraulic filter replacement
Alignment, calibration, and diagnostic scan
System pressure testing (hydraulic/pneumatic)

Tip: If your equipment operates in dusty, wet, or high-impact conditions (like mining or earthmoving), increase service intervals accordingly.

Maintenance in High-Risk Environments

South African conditions are uniquely tough. From highveld dust to rural gravel roads, machinery is often pushed to its limits. Some applications that demand even more attention include:

Mining haulage (due to load weight and terrain impact)
Long-haul trucking (excessive kilometres and variable road conditions)
Agricultural operations (exposure to mud, debris, and chemicals)
Construction work (constant vibration, idling, and uneven surfaces)

At PR Group, we always advise buyers to plan for harsher service schedules in these sectors, and we’re happy to guide maintenance plans for each vehicle sold.

Best Practices for Maintenance Management

To make regular maintenance effective and scalable, consider the following tips:

Create a maintenance schedule for each vehicle
Keep detailed service records (logbooks or fleet management apps)
Train drivers/operators to identify early warning signs
Stock critical spares or partner with a spares supplier like PR Spares
Choose qualified technicians who understand commercial vehicles

If you’re buying used, always request a full maintenance history. At PR Group, all stock undergoes inspection before sale, and we disclose key service details upfront.

Why This Matters When Buying Used from PR Group

Buying a pre-owned truck, trailer, or piece of plant equipment doesn’t mean inheriting problems if it’s been well-maintained.

At PR Group, we ensure:

All units are visually and mechanically inspected
Basic servicing is done before handover
You receive honest assessments of condition and maintenance history
Optional support for parts and service via PR Spares or our trusted network

You can also discuss post-sale service plans or bundle a maintenance check with us before delivery.

FAQs – Maintenance & Equipment Life

Do used trucks come with a service record?
When available, yes. We always provide inspection reports and list known maintenance work.

Can you recommend service providers?
Yes. We work with a network of specialists across SA, and also refer clients to PR Spares for parts and advice.

Do you offer warranties?
Most used units are sold as-is, but we can provide guidance on third-party warranty options.
