Efficient load securing depends on the nature of the goods and starts with the correct transport-suitable packing, loading, stowage and securing of the load. Only goods that are well packed and stowed can be secured and transported in a safe and roadworthy manner.

Forces acting on the load during transport

In normal driving conditions (including full braking, acceleration, evasive manoeuvres and poor road conditions), enormous forces act on the load.

Example: 0.5 G sideways means that cargo with 10 tonnes of net weight can press into the tarpaulin with forces of up to 5 tonnes in weight: 0.5 G = 50% of the net weight.

Due to the shunting of railway waggons in railway stations and the rolling and heeling motions on ships, higher forces act on the load than when trucking on the road.

For Combined Transport, this requires increased load securing measures:

  • Given that the trailers on the railway waggon are loaded against the direction of travel, the load must also be secured from slipping backwards.
  • Ensure optimum weight distribution on the trailer – avoid top-heavy or tail-heavy loading!
  • Before every delivery to the terminal/port or every transfer of the trailer, check again that the load is correctly secured (e.g. sufficient tension in the tensioning straps).

Load securing methods

The "form-fit" load securing method

With "form-fit" load securing, the goods are loaded perpendicular to the boundary of the loading hold (front wall, side panel, stakes, etc.) without gaps between the loads.
Form-fit loading, in combination with XL trailers, is considered a particularly efficient method of securing loads.
If this is not possible due to the nature of the goods, form fit can be achieved with the aid of tensioning straps and tools. Form-fit methods of load securing with tensioning straps are e.g. cross and spring lashing, head-loop or bay-loop lashing.

The "force-fit" load securing method

With "force-fit" load securing, lashing the goods down increases the weight force of the goods, thus achieving a better load securing.
Force-fit load securing: When lashing down the goods, the straps lose lashing capacity with decreasing angles

The "combined load" securing method

With combined load securing, elements of form-fit and force-fit load securing are combined. The load is, for example, loaded to the front wall and lashed down with form-fit and force-fit tensioning straps. In practice, this method of load securing is very frequently used.

Tensioning straps and aids for load securing

A sufficient number of load securing aids (straps, edge protectors, anti-slip mats), in perfect condition, is a basic prerequisite for effective load securing.

Tensioning straps and pretensioning gauge

Tensioning straps are primarily used to produce force-fit and form-fit load securing on the vehicle. By lashing the load down, the weight is increased and a better load securing is achieved. In principle, a distinction is made:

  • Short lever ratchet with approx. 350 daN (kg) of tension force
  • Long lever ratchet with approx. 500 daN (kg) of tension force

The effective tension force generally depends on the force required to tighten the tensioning strap using the ratchet. Therefore, the effective tension force achieved can only be determined using a pretensioning gauge.

Aid: Non-slip mats and edge protectors

In principle, non-slip mats increase the coefficient of friction. However, this quality is only an advantage for certain products. For other products, their use may even have adverse affects (e.g. goods shift on a pallet, increases tipping effect).

Edge protectors not only protect the load and the tensioning strap, they are also an effective aid for securing loads. They distribute the pretensioning force evenly.
