Inertia: Causes unwanted movement of loaded goods
when braking, accelerating and turning
Gravity: Pushes the loaded goods against the
vehicle floor, (this is the force that attracts a body to the
Earth).
Friction: Opposes two interacting surfaces from
sliding over each other. The rougher the surface, the
higher the friction. The friction force helps prevent the
goods from moving. The higher the friction, the smaller
the force needed from securing aids to hold loaded items
in place. The coefficient of friction is measured using the
units μD. The friction force is worked out by multiplying
the coefficient of friction by the weight.
Restraining force: Is the force that the securing aids need
to apply to prevent loaded goods from tipping over or slip-
ping (inertia minus friction).
A decanewton = (daN), is equivalent to approx. 1kg, a
load with a mass of 1000kg will push down on the vehicle
floor with a force of approx. 1000 daN
Friction enhancing matting
The use of friction enhancing matting, (FE matting),
between the floor and the load or between the loaded
goods themselves, increases the
coefficient of friction and reduces the number of restraints
needed to secure a load.
Once the sum of the friction force and the restraining
force is equivalent to the
inertia, sufficient securing aids have been applied to cancel
out the horizontal force.
