Load securing
Operating the body 123
Physical foundations
Forces caused by pulling away, braking
and changing direction act on the load
during driving.
These dynamic driving forces cause the
load to slide if it is inadequately secured
and unstable goods to tilt.
An appropriately adapted driving style
minimises the arising forces and wear
and always provides an increase in
safety.
Section 3, "Speed", of the German Road
Traffic Act (StVO) mentions "Adaptation
of the driving speed to the characteristics
of the vehicle and the goods by the
vehicle driver."
However, in danger situations, even the
best driving style cannot replace load
securing!

Example:
– Inertia force F

= 20,000 daN
– Maximum acceleration forwards = 0.8 g (1 g = force of gravity 9.81 m/s

)
Result: F
G
forwards = 20,000 daN x 0.8 g = 16,000 daN (kg)
The actually required load securing force F
S
is reduced by the amount of frictional force F
R
(between the load and the vehicle
floor) in the case of stable load materials.
Further information on friction-coefficient matchings can be found in the VDI 2700 guideline.
All friction-coefficient matchings apply to clean surfaces.
