Correct load distribution is essential for safe handling and braking. This lesson explains that loads should be placed as low as possible and distributed evenly to maintain a low centre of gravity and comply with axle weight limits. A high or poorly positioned centre of gravity dramatically increases the risk of rollover, especially when cornering or in an emergency manoeuvre.
A load is not static; it is subjected to significant forces during transport. This lesson explains how acceleration, braking (deceleration), and cornering create powerful inertial forces that try to move the cargo. Load securing systems must be strong enough to counteract these forces to prevent the load from sliding forward during braking, backward during acceleration, or sideways when turning.
This lesson details the main techniques used for effective load securing. Blocking involves placing cargo snugly against fixed structures like the headboard or using dunnage to fill gaps and prevent sliding. Lashing involves using devices like straps or chains to either tie the load down, increasing friction (friction lashing), or to directly restrain it against movement (direct lashing).
Using the right equipment is crucial for effective load securing. This lesson introduces common lashing equipment, including synthetic webbing straps with ratchets and heavy-duty chains with binders. It emphasizes the importance of inspecting all equipment for cuts, wear, or damage before use and understanding the labels that indicate their load capacity (Lashing Capacity - LC).
There is no one-size-fits-all solution for load securing. This lesson provides examples of how to secure different common cargo types, from standard palletized goods to challenging loads like pipes, which can roll, or heavy coils. It highlights that the securing method must be tailored to the specific characteristics of the load to be effective.
Heavy vehicles, especially those with a high centre ofgravity, are susceptible to rolling over. This lesson examines the primary causes, including excessive speed on bends or roundabouts, sudden steering manoeuvres, and the 'sloshing' effect of liquid loads in tankers. It reinforces that maintaining a sensible speed and driving smoothly are the best ways to mitigate this serious risk.
While others may have loaded the vehicle, the driver holds the final legal responsibility for the security of the load once on the public highway. This lesson clarifies this crucial point of law, explaining that the driver must inspect the load and its securing arrangements before departure and re-check them during the journey. The consequences of a load shifting or falling can be catastrophic and result in severe legal penalties for the driver.

The most critical factor for vehicle stability is maintaining a low centre of gravity. This is achieved by placing heavier items lower down and closer to the vehicle's centre line. Proper weight distribution prevents the vehicle from becoming top-heavy, significantly reducing the risk of tipping during cornering or evasive maneuvers.
In Switzerland, cargo securing primarily relies on two methods: direct tensioning (lashing) and form-fitting securing (blocking or friction). Lashing involves using straps or chains to apply downward force, while blocking uses physical barriers or friction mats to prevent movement. The choice of method depends on the cargo type and transit conditions.
Several forces can cause a load to shift. During acceleration, inertia pushes the load forward; during braking, it pushes backward. Cornering generates centrifugal force pushing the load outwards. Even vibrations and uneven road surfaces can contribute to load movement over time, highlighting the need for robust securing.
Yes, as the driver, you are legally responsible for ensuring that the load is properly secured before and during the journey. You must verify that all securing devices are adequate, correctly applied, and in good condition. Failure to do so can result in fines, license suspension, and liability in case of an accident.
Blocking is about preventing movement by filling gaps or using physical barriers, often relying on the cargo pressing against the vehicle's structure or other cargo. Lashing, or direct tensioning, uses straps or chains to pull the cargo down and sideways, using friction and tension to hold it in place. Both methods aim to prevent the load from shifting.
Axle load limits are crucial and directly related to load distribution. When loading your vehicle, you must ensure not only that the overall weight is within limits but also that the weight is distributed correctly across the axles. Overloading specific axles can compromise braking, steering, and overall stability, and lead to vehicle damage and legal penalties.
