2.3 TECHNOLOGY “C”
In the case of systems of the C technology, swap bodies (upper structures of trailers or semi-trailers
without the under body (chassis)) and containers are carried and handled. The swap container is a
loading unit adjusted to the dimensions of a road vehicle and fitted with struts underneath to change or
“swap” between the road and railway transport mode. It is typical for the combined transport of C
technology that the system “lift and drop” by means of mobile cranes is used for loading and
unloading. Wagons for the transport of swap bodies and containers may be special pocket wagons,
spine wagons or flat wagons of a standard construction. These wagons are mostly without sides or
these are very low; they have a flat floor which can bear high loads. Because it is possible to carry
higher consignments the floor of wagons is as close to the upper edge of the track as possible. Air
bags must be fitted into the road cargo vehicles so that swap containers may be discharged on
specially incorporated struts/legs and the user loads or unloads goods as he wishes. The length of
swap bodies is between 6.35 m and 13.5 m, but the most frequent length is 7.15 m with a constant
width of 2.5 m and height of 2.6 m. The four-axle flat wagon with a loading length of 14.6 metres and a
load bearing capacity of 45 tonnes is the most suitable for the transport of swap bodies. Its loading
length enables the transport of two swap bodies with a length of 7.15 m with the full utilisation of the
loading length. This wagon also enables the carriage of a combination of swap containers, swap
bodies and containers.
