If the freight requires a position during transportation where the height of the load is significantly greater than the sides or diameter, its stability is impaired. In this case, there is a risk that the load could tip during acceleration, so that additional securing is required.
Securing against tipping
After securing against sliding using forced or positive locking, the second stage is to secure against tipping. The lashing equipment used for this secures the load against tipping by the tensile force and not the pretension force. If forced locking lashing down is used to secure against sliding, this lashing equipment can also be used simultaneously to secure against sliding and tipping.
Non-stable loads of the same format can be embraced into a unit using a lashing strap. Thereby, the relationship height to base area is positively changed. This unit must now only be secured by the conventional means.
For the transportation of non-stable freight, e.g. stacked crates of drink or barrels, vehicles specially designed for the freight are used. Thereby, the reinforced body and equipment provide positive locking and ensures security against tipping. This then negates the need for the application of tensioning straps. When transporting beverage crates on well pallets the sides are interlocked using the swivelling support laths.
This simple calculation is an option for estimating the stability:
The distance D (tipping edge to the centre of gravity) is divided by the height of the centre of gravity h.
If the result is less than the following values, effective action should be taken to ensure stability:
minimum 0.8 (forwards)
minimum 0.7 (sidewards)
minimum 0.5 (rearwards)
