Episode 29: Discard maturity of lashing straps – The criteria

Load securing on/in trucks is usually form-fit or force-fit. I described what the form-fit method is all about and what you need to bear in mind in episode 23.

In this episode, the securing device “tension belt” will be described in more detail, especially from the perspective of “discard maturity”.

Discard criteria for lashing straps

Another set of rules is VDI-2700 Sheet 3.1 “Instructions for use of lashing equipment” 03-2023. The definition of damage is new. The directive specifies a measurable value here.

Damage must not exceed 10% of the cross-section. This applies to both the width and the thickness of the material. In practice, damage is often not sufficiently taken into account in relation to the material thickness.

With a webbing material thickness of approx. 3 mm, damage of 10% = 0.3 mm is quickly reached.

Both belts are ready to be discarded.

Excessive wear is also a discard criterion. This is not easy to assess. The picture shows a belt with the kind of damage that occurs when the same load is always secured. Edge protection angles or hose edge protection would prevent such damage.

This belt is ready for discarding.

Such damage occurs when the belt is hooked in and the insertion slats then rest directly on the belt. This will inevitably damage it.

This belt is ready for discarding.

Belts that are damaged at the seams or have been improperly repaired or manufactured, as shown in the pictures, are not permitted and must not be used.

This belt is ready for discarding.

Excessive rust due to improper storage or storage on the vehicle.

This belt is ready for discarding.

This damage to the webbing indicates improper handling.

This belt is ready for discarding.

Such damage to the ratchet occurs if the operator uses a bar, nailing iron or metal pipe as an extension of the clamping lever. The maximum manual force of 50 daN was far exceeded.

Extensions are generally not permitted unless they are specially designed for this purpose.

This belt is ready for discarding.

Damage to a belt due to overstretching caused by an impermissible lever extension. Only 35 mm of the original belt width of 50 mm remains.

This belt is ready for discarding.

The buckling test

Example: The damaged belt is hanging on the insertion bar.

The buckling test shows that the belt is definitely ripped because the damage is more than 10% of the material thickness.


It is important that the belts on a vehicle are checked regularly. This is the responsibility of the driver as the user, but also of the vehicle owner. The driver is obliged to check the belt for discarding before each use.

The vehicle owner must provide written proof that the seat belts have been checked at least once a year by an expert.

However, the loader (managing director or appointed representative) must also ensure that no belts that are ripe for discarding are used in the specific loading situation. In the event of an incident that would result in an administrative offense, but in any case with criminal consequences (e.g. negligent bodily injury), the shipper would also be responsible. The best way to do this is with a checklist for an incoming goods inspection, which includes the point of the belt check and forms part of a work instruction.
