News!!
Palfinger
to start new RPA (Rapid Assembly) program in Niagara Falls. Palfinger
Inc. will start to assemble new cranes in the Niagara Falls plant
starting in early 2003. The program will enable faster delivery times
for knuckle boom cranes to the North American market as well as
enhance parts availability.
| New
KTL painting process now in use |
 |
|
|
To
answer the first question in advance: KTL is the German
abbreviation for cathotic paint system. With this system, which
represents the latest state of the art for paintwork technology,
PALFINGER is once again setting new standards with regard to
quality and service life at the Marburg and Lengau production
plants.

**Wire
shot knuckle boom prepared for dipping process**
The KTL process has been used successfully for a number of years
now in the auto industry and is leading to longer and longer
warranty periods as far as corrosion damage is concerned. KTL is
being deployed by PALFINGER as a new development in the sector
for painting all crane components as well as for all other
product groups. In contrast to conventional spray priming and
painting, in KTL painting the coat of paint is applied evenly
over the entire surface. The process also ensures that the
primer coating without exception also gets into the cavities
which cannot be reached in a normal treatment process. The
result: Optimal corrosion protection for all components.

The crane components are disgreased, rinsed and activated in the
individual dip-tanks (12 in total) and then covered with zink-phosphate.
Then they are rinsed again, deactivated and after another
rinsing with superclean water they are coated with electrostatic
KTL.**
16 work steps ensure the high level of quality
The elaborate surface paintwork is applied in 16 steps. In this
process the individual pre-treatment steps already ensure 90% of
the quality before the actual paintwork is applied. By blasting
the metal with wire shot, an extremely aggressive blasting
medium, the layers of scale present on hot-rolled sheet and
plate and the impurities caused by welding are completely
removed.
The parts are then degreased in two baths, rinsed twice and
evenly activated. This is followed by zinc phosphating – a
galvanising method similar to that used in the auto industry.
After two further rinses the surfaces are then passivated and
the parts are rinsed once again, with ultra-clean water in a
quality of below 20 μS/cm.
Not until all of these steps have been completed can the
electrostatic KTL coating process take place, in which the part
is completely immersed in the paint. It becomes the negative
pole, while the immersion bath is positively charged by means of
anodes. This makes it possible to achieve an even coating
thickness and at the same time ensures that the paint reaches
every single point on the part – a comparison could be drawn
here with cavity sealing. The coating thickness can be adjusted
in the range of ± 1 – 2 μ. Excess paint is washed off in
two further work steps in an ultra-filtration bath; then the
paint is baked on in an oven at a temperature of 115o C for 1½
hours. At this comparatively low temperature – the auto
industry applies a temperature of approx. 160o C –
temperature-sensitive parts can also be coated without any
problem. After transport to the second level there are two
options for further-processing. Components which only had to be
coated are transported down to the pre-assembly area. Parts such
as the base frame, crane column and boom system are additionally
painted in a further work step with water-soluble,
environmentally friendly two-component paints by means of a
spray robot. The robot system is programmed to handle all
components and to recognise size and shape by means of the chip
assigned in each case. Depending on the part, this process can
take up to six hours. Only two people work in this unit. Four
more people are required on the handling side, for hanging up
and removing the parts.

The advantages of the KTL process are impressive
PALFINGER uses a special KTL material from DUPONT which exhibits
excellent properties also as a single-coat material. Wolfgang
Pilz, who is responsible for the development of these facilities
at PALFINGER: “The primers normally used are divided into two
systems which entail various advantages and disadvantages. Epoxy
primers offer e.g. excellent corrosion protection, but are not
resistant to outdoor weathering. Over the course of time the
coating deteriorates as a result of exposure to UV light.
Acrylic primers display a high resistance to weathering but
provide less protection against corrosion. The material
specially developed for us is different. Even applied as just a
single coat, if we only use KTL material in a coating thickness
of 30 μ without any additional topcoat, it meets the
requirements of a 700-hour salt-spray test. This involves a
precisely specified testing procedure: The painted part is
damaged by a precisely defined cut through the paint down to the
base material. The salt spray test is then conducted. Next, the
corrosion creep is measured at the cut, and we must not exceed a
maximum value of 1 mm creep. This results in the specified 700
hours. If a topcoat is additionally applied we reach 1,000 hours
and over in the test.”

environmentally friendly**
ENVIRONMENTAL protection writ large
The exhaust air from the ovens and the painting booth as well as
from the evaporation zones merely reaches a level of 6,000 m³.
This exhaust air is treated in a thermal combustion process and
the heat is recycled. Wolfgang Pilz: “We use it to heat the
lower and upper oven. Any heat left over is supplied to the
heating and hot water system for the PALFINGER plant at Lengau.
The baths too are included in an automatic regeneration process.
The dirty water is treated in a vacuum distillation process and
recycled. As a result, the system functions completely without
any waste water. There are no toxic substances anywhere in the
process.”

**Final
drying process**
With the new KTL facility at the Lengau plant PALFINGER is not
only achieving a quantum leap in the quality of its products.
The manufacturer is also contributing to a drastic reduction in
the burden on the environment.
