Future comfort
is our mission
SOME SUPPLIERS to the automotive industry feel
threatened by the constant endeavors of customers to
simplify and reduce weight. They fear this could result
in certain automotive components actually being elim-
inated in future designs. For Trelleborg, this trend is an
advantage, since our technology allows the replacement
of metals with polymers. Moreover, the need for anti-
vibration systems, which is one of our core competen-
cies, is rising continuously rather than declining, as
people demand greater comfort from their vehicles.
   Naturally, we cannot rest on our laurels. Our contri-

 Running on 100-percent biodiesel, the trimaran Earthrace
 made its way around the world and re-entered Sagunto port on
 Spain’s Mediterranean coast in late June. The team on board
 wanted to break the world record for the fastest round-the-world

 boat trip. And they succeeded.   TEXT: Nick Terdre PHOTO: Peter Faretra and Earthrace

»         after leaving the port
         of Sagunto on Spain’s

         Pete Bethune needed to

1998 at just under 74 days. In fact,
he knocked 14 days off the record.

Railway and metro operators are seek-
ing to offer their passengers ever-
increasing comfort. The new Movia 237
trains for the London Underground’s sub-
surface lines are air-conditioned and
offer improved access, as the low-profile
design of the bogies ensures that the
carriages will be at the same height as
the platforms. This has meant that the
space envelope for the secondary sus-
pension, which has been supplied by
Trelleborg Industrial AVS under contract
from Bombardier Transportation, is
severely constrained. Trelleborg has met
this challenge with a low-profile solution
that combines an air spring with a new
design of Metalastik half hourglass spring.

Trelleborg specializes in agricultural tires for various applica-
tions, such as tractors. Following the brand switch from Pirelli
Agricultural, Trelleborg Wheel Systems recently launched the
TM700 tire range branded under the Trelleborg name. Fitted
on a tractor, with front and rear ballast set at 1.2 and 1.6 bar,
the TM700 ensures stability and the tire provides good han-
dling and comfort on the road. Vibration is also minimized
through the shape of the lug and deflection, which decreases
the stress and strain on the driver.

   The Dracone

     The Dracone barge may not be a
     household name, but for coast guards
     around the world, this gigantic rubber
     bladder is part of the first response kit

         How it cleans
         When an oil spill occurs, the oil is first contained with so-called booms.
         Skimmers, containers floating on the water surface, then set to work
         collecting the oil, water and other debris into a funnel, with the help of
         a pump attached to a hose at the bottom of the skimmer. The spill is
         pumped into the Dracone barge for discharge at land-based disposal

         935 cubic meters of liquid, is 91.5 meters long, 4.23 meters in
