engine, axle and transmission assembly
From rough metal, advanced engine parts are
manufactured. Aluminium parts are made in a
die-casting process, and steel parts are forged in
a typical heavy industrial environment. Small
components are manufactured in series in precision
machine shops. When all components are
completed, the engine, axles and transmissions are
assembled and tested together on hot test stands.

It is vital that the illuminance matches the task.
As tasks can vary significantly from one location
to another, care must be taken that each specific
working area has a suitable lighting solution. On
the assembly lines, limitation of glare is important,
especially when recessed luminaires are used at
heights of less than 2.5 meters to obtain the
required high illuminance.
Metal forming takes place in areas where oil and
cooling liquid are used. Luminaires must be oil-
resistant and, if soiled, they must be easy to clean.
Where strong vibrations are present in heavy
industry, luminaires must withstand this
mechanical stress.
Typical lighting installation
Because these plants are part of the metal
industry, not all possibilities are shown.
Normally, mainly general lighting is applied in
the manufacturing halls, which are common
in this type of industry.
