When it comes to transporting heavy, oversized, or unusual loads, you’ll often come across the term abnormal load specifications. This refers to the legal requirements and guidelines for anything exceeding standard vehicle dimensions and weights. So, what makes a load “abnormal,” and why are these specifications important?
What Makes a Load “Abnormal”?
Any shipment that exceeds the legal road limits for weight or size. While these limits can vary from one country or region to another, in general, any load that exceeds the following thresholds is considered abnormal:
- Weight: Anything over 44 tons (or 40,000 kg) is usually classified as an abnormal load.
- Dimensions: If a load is wider than 2.55 meters, taller than 4.3 meters, or longer than 18.75 meters, it falls into the abnormal category.
Abnormal load specifications in South Africa are defined by South Africa’s Road Traffic Act and TRH11 guidelines:
- Width: More than 2.6 metres
- Height: Over 4.3 metres (loaded)
- Length: Exceeds 22 metres
- Mass: More than 56 tonnes gross combination mass (GCM), or where a single item exceeds axle loading regulations
Once these limits are exceeded, you’ll need a special abnormal load permit outlining the dimensions, weight, approved route, travel times, and required escort arrangements. Failing to adhere to abnormal loads specifications could result in accidents, fines, and significant delays, not to mention damage to infrastructure.
Key Specs for Transporting Abnormal Loads
Transporting abnormal loads involves much more than just getting from A to B. Here are the essentials:
- Paperwork: Special permits from road authorities are mandatory and must detail exact routes, travel windows, and safety measures.
- Route Planning: Abnormal load specifications mean the cargo needs to be moved on specific routes to avoid things like narrow bridges or low-hanging power lines. Route planning is super important, and one needs to work closely with local authorities to mark out the safest and most practical path.
- Escort Vehicles: Depending on the size and weight of the load, it might be necessary to have one or more escort vehicles. These vehicles help to clear the road, provide warnings to other drivers, and ensure that the load moves safely. They also help to guide the transport vehicle through tricky areas, such as tight corners or low bridges.
- Time Restrictions: Due to the potential disruption that abnormal loads can cause, many regions impose time restrictions on when these loads can be transported. In most cases, abnormal loads are only allowed to move during off-peak hours, like at night or on weekends, to minimise disruption to regular traffic.
- Specialised Equipment: Low-loader trailers, extendable platforms, and multi-axle trucks help distribute weight, handle challenging cargo dimensions and prevent road damage.
- Safety Precautions: Given the size and weight of abnormal loads, safety is a top priority. Loads must be properly secured, and transport teams trained to handle these unique challenges with care.
Why Do Abnormal Load Specifications Matter?
The goal of abnormal load specifications is simple: safety – for infrastructure, public and your cargo. Moving abnormal loads can cause major disruptions and risks, including:
- Heavy loads can damage roads and bridges if they are not properly transported.
- Oversized vehicles can be difficult for other drivers to navigate around, especially on narrow or busy roads.
- Non-compliance can lead to hefty fines and delays, not to mention reputational damage.
