Diagonal lashing vs. cross lashing – differences in load securing
In the following we explain diagonal lashing , give a practical explanation of diagonal lashing and show the differences to diagonal lashing .
What is diagonal lashing?
- Diagonal lashing definition : The load is secured in such a way that it cannot move forwards, backwards or sideways.
- Diagonal lashing principle : The straps run diagonally from the lashing points on the vehicle to the load at a specific lashing angle. This creates a stable, form-fitting connection in all directions.
- Typically four straps are required – two each facing forward and two facing backward.
What is diagonal lashing?
- With diagonal lashing, the straps are not led diagonally across, but diagonally from the lashing points on the vehicle to the load.
- The aim is also to provide force-locking security in several directions.
- The method is often used when there is not enough space for the classic diagonal lashing.
The correct lashing angle for diagonal lashing
- Vertical angle (α) : Should be between 30° and 60°.
- Horizontal angle (β) : Optimal between 6° and 55°.
Differences between diagonal lashing and diagonal lashing
| criterion | Diagonal lashing | diagonal lashing |
|---|---|---|
| Number of belts | 4 (crosswise) | usually 2–4 (oblique) |
| Form closure | In all directions | In selected directions |
| Lashing angle | precisely calculated | more flexible, depending on the structure |
| Application | heavy, compact load | limited space |
| Principle of operation | full bracing | partial guying |
Both methods are recognized methods of securing loads and are justified depending on the type of transport.

Conclusion on diagonal lashing vs. diagonal lashing
- Diagonal lashing offers maximum stability through positive securing in all directions.
- Diagonal lashing is a flexible alternative in confined spaces.
