7 IDENTIFICATION OF REQUIRED CARGO SECURING
FUNCTIONS FOR SOME CARGO TYPES
This chapter deals with the general requirements on railway wagons in order to obtain a
rational securing <strong>for</strong> some types <strong>of</strong> cargo. The required functionality <strong>for</strong> each type <strong>of</strong> cargo
has been specified.
7.1 Steel sheet
The securing <strong>of</strong> steel sheet in packages is regulated by Chapter 1.2.3 in RIV Loading
Guidelines, App II, Section 2. The sheets should be bound together into packages. The
packages should be bound together both sideways and lengthways. The loading method
prescribed in the guidelines permits the goods to slide in longitudinal direction in the wagon
(minimum clearance 50 cm). The slabs should be blocked by nailed timber sideways. If the
packages include timbers bound in lengthways, friction inserts can secure them sideways.
If the wagons have strong ends no minimum clearance is needed and the wagons loading area
could be better utilised. A system <strong>for</strong> adjustable transverse blocking would exclude the use <strong>of</strong>
guide-pieces and higher stacks with more tiers could be allowed (depending on blocking
height). A floor with high friction (µ at least 0.7) and/or damping qualities would exclude the
need <strong>of</strong> friction inserts and/or guide-pieces. It is important to know the strength <strong>of</strong> the ends
and the blocking.
