The
walls of open-top containers are generally made of
corrugated steel. The floor is made of wood.It has the
following typical distinguishing structural features.
The roof consists of removable bows and a removable
tarpaulin. The door header may be swivelled out.
These two structural features greatly simplify the
process of packing and unpacking the container. In
particular, it is very easy to pack and unpack the
container from above or through the doors by crane or
crab when the roof is open and the door header is
swivelled out.
It should be noted, however, that the purpose of the
roof bows of an open-top container is not solely to
support the tarpaulin but also to contribute to
container stability. Flatracks are therefore more
suitable for overheight cargoes.Lashing rings, to which
the cargo may be secured, are installed in the upper and
lower side rails and the corner posts. The lashing rings
may take loads of up to 1000 kg.Usual open-top container
dimensions are 20' and 40'.
