Warning: transported goods are subject to both
horizontal and vertical forces. Vertical forces must also be
catered for if loads are to be safely
transported (e.g. by the use of ratchet straps).
When strapping down, it is essential to observe the vertical
angle alpha (angle between the strap and the load area, as
measured at the lashing point, must be between 65° and
90°).
Stability of loaded goods
Bs = Distance from the centre of gravity to the tipping point
■ ■
Hs = Height of the centre of gravity
■ ■
c = Coefficient of acceleration (e.g. 0.8 in the direction of
■ ■
travel - see page 27)
A load is stable when:
When braking:
When cornering:
When accelerating:
4.3 Types of load restraint
Lashing down (physically strapping something to the floor)
■ ■
Diagonal lashing, horizontal lashing (strapping interlocking
■ ■
items in position)
Restrict the movement of a load with the help of partitions,
■ ■
clamping bars, nets etc.
The simplest method of securing goods is to load them
against a bulkhead or an endframe.
