The aim is to give a seamless journey, and the best
way of achieving this is to use modular or unitised
loads.
• In effect, all materials are put into standard
containers, and the equipment is arranged to move
these containers.
• The basic container is a metal box 20-feet long. This
size has become somewhat restricting, and it is often
replaced by a 40-foot box.
• Putting materials into these boxes eliminates the
need to handle items individually, and the whole
container goes from source to destination.
