Transport Month is a reminder of how much South Africa depends on a reliable transport network. For abnormal-load operators, keeping that network moving comes with added complexity.

Routes must be carefully planned, schedules tightly managed and prime movers prepared for heavy loads, steep gradients and prolonged low-speed operation. These conditions can increase engine and drivetrain demands while reduced airflow places additional pressure on thermal management.

For the operator, reliability starts well before the vehicle leaves the yard.

Why do abnormal loads put more pressure on a prime mover?

Unlike conventional long-haul transport, abnormal-load operations can involve prolonged high engine loads, significant torque and low-speed running. Without the airflow generated at highway speeds, the prime mover and its cooling system can face additional thermal demands.

This makes effective lubrication and thermal management critical. Engine oil needs to maintain protection under demanding conditions, while the cooling system needs to manage heat and protect against corrosion, cavitation and deposits.

“With abnormal loads, it is important to look beyond the weight being transported and understand what the operating conditions are doing to the equipment,” says Eben Viljoen, Business Development Specialist - Commercial Vehicles at FUCHS. “Low-speed, high-load applications can create a very different thermal and mechanical environment from normal highway operation.”

How does the right engine oil support heavy-haul operations?

There is no single lubricant that is automatically right for every commercial vehicle. Engine design, emissions technology, manufacturer requirements, operating conditions and service intervals all need to be considered when selecting an oil.

The TITAN CARGO range, with many OEM approvals and high specifications, offers heavy-duty operators a choice of high-performance lubricants for demanding commercial vehicle applications.

TITAN CARGO SAE 15W-40 is a high-performance, fuel-efficient engine oil designed for commercial vehicle diesel engines. It supports extended service intervals and provides reliable protection for engines equipped with turbochargers and exhaust after-treatment systems.

For newer commercial vehicles, TITAN CARGO FLEX LD SAE 10W-40 has been specially developed for engines fitted with modern exhaust after-treatment systems and turbochargers. It helps improve fuel economy, ensures excellent cold-start performance, and reduces oil consumption.

TITAN CARGO LD3 EVO SAE 10W-40 is specifically engineered to support extended service intervals and carries OEM approvals, making it a dependable choice for modern heavy-duty fleets.

Why is coolant important when moving abnormal loads?

Engine protection is only part of the reliability equation. Heavy-haul operations can also place significant demands on the cooling system, particularly during prolonged low-speed operation when reduced airflow can make effective thermal management even more important.

The FRICOFIN range offers ready-to-use coolant solutions developed to meet the requirements of different engine technologies and operating conditions.

FRICOFIN LD 50 is a ready-mix X-OAT coolant designed to deliver long-lasting protection against overheating, corrosion, and deposit formation. Its 50% premixed formulation ensures the correct coolant concentration and eliminates the need for on-site dilution.

FRICOFIN LL 50 is formulated for heavy-duty engines operating under demanding conditions and extended service intervals. It provides reliable protection against corrosion, cavitation, and overheating, while its ready-to-use formulation helps maintain consistent cooling performance across the fleet.

For modern high-performance commercial engines, FRICOFIN DP 50 utilises advanced Si-OAT technology to protect against overheating, corrosion, and cavitation. Premixed with demineralised water, it ensures the correct coolant concentration is maintained while reducing the risk of mixing errors during servicing.

What makes the FUCHS approach different?

For FUCHS, lubrication is not simply about supplying a product. It is about understanding the application. 

This means considering the engine, equipment, operating environment, manufacturer specifications and service requirements before recommending a solution. For abnormal-load transport, where operating conditions can differ significantly from conventional road freight, this application-focused approach matters.
