of the trailer. Guideline specific weight of
selected materials is given in table (4.1).
Take care not to overload the trailer.
Loading bulk materials is normally con-
ducted with the use of loaders or con-
veyors and possibly loading manually. Do
not load bulk materials to a height greater
than that of side walls or extensions. On
completion of loading, the load should be
evenly spread over the whole surface of
the load box. If the trailer is equipped with
wall and extension linking cables, they
should be connected with a linking cables
when loading loose materials. Secure
cable release mechanism with cotter pin.
Oilseed rape or seeds of other plants of
very small size or powder materials can
be transported provided the load box is
properly sealed in places where gaps are
bigger than the seed diameter or other
carried material. Profiled rubber seals, sil-
icone sealers, plastic wrap, rope or textile
materials are recommended materials to
provide sealing of the load box.

BULK MATERIALS
Additionally it is essential to protect load
with tarpaulin cover. It protects the load
against spilling during travel, being blown
away by the wind and also protects load
against moisture, which is particularly
dangerous in the case of bulk materials.
They may absorb a significant amount of
water, which may increase the bulk of the
load during travel. In extreme cases the
gross weight of the trailer may exceed the
permissible vehicle gross weight.
Some bulk loads (e.g. building materials,
such as gravel or slag) may cause more
rapid damage to paintwork.
LOADS OF PIECES OR SOLID LUMPS
Loads of pieces or solid lumps are gen-
erally hard materials of significantly
greater dimensions than bulk loads
(stones, coal, bricks and ballast). These
materials without prior preparation of the
load box may cause indentation of the
floor or walls and abrasion of paintwork.
In order to protect it, lay thick plywood,
hard particle board, thick planks or other
materials of similar properties on the load
