Pall Dynamics Limited (PDL), founded
in 1984, is dedicated to designing and manufacturing
friction dampers with uncompromising emphasis on
quality and integrity. Over the years, Pall Dynamics
has earned an international reputation for excellence
and is a world leader in friction dampers for seismic
control.
Inspired by the principle of friction
brake, Dr. Avtar Pall, a structural engineer, pioneered
the development of Pall Friction Dampers for the
seismic control of buildings. Pall Friction Dampers
significantly reduce the initial cost of construction
while dramatically increasing the earthquake resistance
against damage.
Friction dampers for buildings
must possess reliable and stable performance over
the life of building. Developing a reliable friction
is very difficult and tricky. Over a period of more
than a decade of research and development, the common
problems in friction were successfully overcome
by using specially treated surfaces and a unique
manufacturing process.

Pall Friction Dampers are well recognized and accepted
by building codes in Canada, the U.S and other countries.
The first building with seismic
dampers in North America was built with Pall Friction
Dampers (1987). Pall Friction Dampers are finding
increasing application worldwide for new construction
as well as for retrofit of existing buildings. They
have been used for the seismic protection of more
than 170 major buildings in the U.S., Canada, China,
Colombia, India, Indonesia, Iran and Philippines.
Some of the building projects completed are:
|
-
U.S.A: Boeing Commercial Airplane Factory at
Everett - the world's largest building in volume,
and three Boeing Development Center Buildings
at Seattle; Moscone Convention Center in San
Francisco - California's largest project of
2001; ACC Sharp Hospital, San Diego; Monterey
County Government Center; St. Joseph Hospital,
Tacoma; 3-Million Gallon Water Tank, Sacramento;
Alaska Airline Hangar, Seattle.

-
India: Several buildings are being designed
and built under Technology Transfer of Know-How
to UNITECH Ltd., New Delhi, India (www.unitechgroup.com).
Technology Transfer of Know-How:
If a large segment of society in earthquake
prone countries is to benefit, the friction dampers
should be locally manufactured so that they are
less expensive to make and affordable to all.
This can be achieved through Technology Transfer
of know-how to manufacture quality friction dampers.
Reputed
companies,
interested in acquiring Know-How
for the manufacture and marketing of Pall Friction
Dampers in one or more or all of
the following regions, should contact PDL:
1. Asia (less India): China, Japan, Iran, Indonesia,
Philippines, Pakistan, including New Zealand, Fiji
2. Europe: Greece, Italy, Turkey, Romania, Yugoslavia,
including Algeria, Russia
3. North America: the U.S, Canada, Mexico and Caribbean
region
4. South America: Colombia, Chile, Peru, Ecuador,
Venezuela, Argentina
