Title: The principle of unit loads


1
The principle of unit loads
Goods should be kept together in form of a
transport unit adapted to all present vehicles
and handling equipment. The unit should be formed
as early as possible and be broken as late as
possible in the material flow. Preferably should
be formed at the consignor s, ad broken at the
consignee s.

Unit loads
  • Unit loads are parts of a shipment that can be
    treated as a single unit during cargo handling
    and transportation.
  • The size or dimensions of the unit load can vary
    according to requirements and to the means of
    transport and packaging container available.
  • To optimize the cargo handling, transport and
    storage processes, standardization of unit loads
    is desirable.
  • The most common unit loads are pallets and
    components with bases that resemble pallets, such
    as pallet, etc.
  • The most important properties of a unit load are
    that it can be loaded to ensure a tight fit, its
    modularity and its stability, the last of which
    ensures that it can be stowed safely and will not
    be damaged by load securing measures.

Characteristics of an unit load
  • Large as possible
  • Formed as early as possible
  • Broken as late as possible
  • Be stable and rough
  • Be able to be handled by all equipment in the
    transport chain

4
Benefits of using unit loads
  • Simpler, faster and cheaper trans-shipments
    between transport modes
  • Reduced terminal times for vehicles leading to
    better resource utilisation
  • Less goods damage and costs for wrapping
  • Easier to choose load unit type
  • Easier document handling

5
Costs of using unit loads
  • Need for technical adaptation
  • Need for larger and more costly transhipment
    equipment
  • Economies of scale cause less flexibility
  • Extra costs for unit loads and empty positioning

Full loads, part loads, general cargo and parcels
simple operations low entry barrier more
difficult operations often with general
cargo consolidation in terminals requires a
network large economies of scale speed is
essential
