CONCLUSION:
Sliding didn’t occurred until the sum of the pre-tension
pre
on both sides had been
reduced to 250 kg. Thus, static friction should be used in combination with top over
lashings, when dimensioning cargo securing arrangements.

CONCLUSION:
A cargo securing arrangement with top-over
over lashings, designed in accordance with
IMO/ILO/UN ECE Guidelines, provide sufficient safety against tipping, whatever side the
tensioning device is applied at and even during extreme vehicle operation.

Dynamic driving tests carried out by DEKRA
Practical inclination tests
Theory behind the tests
Basic design requirement:
S = m (ah - µ × av )
Practical inclination test:
S = m (sin α - µ × cos α)
The support S shall be equal in basic design and test and thus:
m (ah - µ × av ) = m (sin α - µ × cos α)
Practical inclination tests
Practical tests
Practical tests can be worked out for determining the coefficient of friction for
different types of combined materials, in purpose of controlling the function of
the lashing arrangement.
