The concept of unit load explains that a single unit of an item
or multiple units arranged or restricted that they can be handled
as a single unit and maintain their integrity. Most consumers or
industrial products move through the supply chain in unit form for
at least part of their distribution cycle. Unit loads can make
handling storage and distribution more efficient. A typical
approach to unit load size determination are based on the physical
configuration of the container or pallet used to group the parts,
on batch size, or on the constrains of the material handling
device. The most important advantages of unit loading are more item
can be handled at same time, thereby reducing number of trips
required and can be reducing handling cost, loading and unloading
time and product damage; it enable the use of standardised material
handling equipment. Time spent forming and breaking down of unit
loads, cost of containers or pallets and other load restraining
materials used in unit and need of returning the empty containers
or pallets to the point of origin are the major drawbacks of unit
loading.
If we are thinking of the making of any type of home appliances,
basically it is large in size and restrictions occurred during its
handling. The major components considered are move cost and holding
cost. Move cost consist of equipment and operator cost incurred
when the load is transferred. The moving equipment and the operator
costs are directly related to the mean transfer time that the load
experience. Let us consider the case of home appliances, when a
request is made to move the unit load of these appliances must wait
until the material handling device is available, at which time the
transfer can be take place. During the time where the load reaches
from the producer to its wholesaler, there is a delay occurred at
the working centre. In manufacturing sector a unit load may be a
group of parts handled in a container, tote, box or pallet and
moved as a unit. In the distribution of this manufactures, unit
load may be a package or several packages held together in a larger
box or on a pallet. By reducing move frequency the total move
distance and consequently handling cost is reduced.
Unit cost is one of the most economical approaches to reduce the
manufacturing costs and to build efficiency into material handling.
The impact of unit loads pervades several aspects of manufacturing,
ranging from raw materials warehouse through production on the shop
floor to furnished product storage and warehouse. Because material
handling is felt through entire spectrum of manufacturing and given
that handling and storage unit is a major component in material
handling. During the shipment of this furnished products, the
material handling and its packing become different. This time there
should be clean and well planned packing’s were shipped. One of the
input requirements for material handling system selection is the
number of moves to make. These moves equal to the number of unit
load transfers to be made between stations. Most popular way of
moving the furniture products using unit loads are use of lifting
device under mass of loads, inserting lifting elements into the
body of load, squeezing the load between two lifting surface etc.
The most important platform used for these type of handling are
pallets (paper, wood, plastic, metal) and skids (metal and
plastics).
