CPC Load Security

Question 1

Under UK law, who is responsible for ensuring a load is properly secured on an HGV?

Accepted Answer

The driver is ultimately responsible for ensuring the load is secure before driving

Answer

While the loader has a duty to load safely, the driver is ultimately responsible for ensuring the load is secure before and during the journey. The driver can be prosecuted if an insecure load causes an incident, even if someone else loaded the vehicle.

Question 2

What is the purpose of load restraint calculations?

Accepted Answer

To determine the force required to prevent the load from moving during braking, acceleration, and cornering

Answer

Load restraint calculations determine the forces that will act on a load during transport (particularly during emergency braking) and ensure sufficient restraint is in place. The standard requirement is that restraint must withstand forces equal to the total weight of the load forward.

Question 3

When using ratchet straps to secure a load, what should you check before use?

Accepted Answer

That the straps are not damaged, are within date, have readable load ratings, and the ratchet mechanism works correctly

Answer

Before use, ratchet straps should be checked for damage (cuts, fraying, UV degradation), that the manufacturer's label is readable with load ratings visible, that the ratchet mechanism operates freely, and that the hooks and fittings are not bent or damaged.

Question 4

What force must the load restraint system be capable of withstanding in the forward direction?

Accepted Answer

The total weight of the load (100%)

Answer

The load restraint system must be capable of withstanding a forward force equal to the total weight of the load. Sideways restraint should be 50% and rearward restraint 50%. This accounts for forces generated during emergency braking.

Question 5

Why is it important to distribute a load evenly across the trailer floor?

Accepted Answer

To ensure axle weights are within legal limits and the vehicle handles safely

Answer

Uneven load distribution can cause individual axle weights to exceed legal limits, affect vehicle stability and steering, increase the risk of rollover on corners, and cause uneven tyre and brake wear. The load plan should ensure weight is spread appropriately.
