MILWAUKEE--(BUSINESS WIRE)--
Actuant Corporation's Enerpac unit, a market leader in high-force
hydraulics, is playing a key role in the largest public works project in
California history, the San Francisco-Oakland Bay Bridge.

The signature architectural feature of the bridge is a self-anchored
suspension system which includes a 1,263 foot main span containing a
single, continuous support cable. This cable is built into the roadway
span itself and is anchored at each end of the span while passing up and
over a dramatic 525 foot support tower. To accomplish this asymmetrical,
non-traditional suspension, the bridge must be fabricated in sections
which then are lifted onto large skids until they can be moved into
position. Enerpac systems were used to align the deck sections and erect
several cross beams that connect these deck sections. In addition,
Enerpac's digitally controlled synchronous jacking and strand jacking
systems are being used to help construct the span's massive 525 foot
support tower.
"Enerpac's technology for the new San Francisco-Oakland Bay Bridge
construction is state-of-the-art," said Mark Sefcik, President of
Enerpac. "Our systems are able to accurately position and lift cross
beams with extreme precision in order to facilitate the construction of
this uniquely designed, self-anchored suspension span. This week, the
third set of four tower sections was successfully lifted into place
utilizing our strand jack system with the final section expected to be
completed in March 2011."
Enerpac is a global leader in delivering hydraulic solutions for the
controlled movement and position of structures, and its technology has
contributed to the successful completion of a number of the most
recognizable structures on Earth. Enerpac provided the synchronous
lifting unit for three gigantic stages for U2's Global 360 tour and also
provided the hydraulic lowering mechanism that positioned the "Bird's
Nest" stadium into place prior to the Beijing Olympic Games. Enerpac's
technology has also helped position other famous bridges including the
Millau Viaduct in France, Kealakaha Steam Bridge in Hawaii and the Third
Millennium Bridge in Zargoza, Spain, among others.
"Enerpac has a reputation for creating innovative solutions for
significant construction projects globally. We are a leading global
supplier of customized hydraulic lifting systems because of our ability
to engineer custom results," said Sefcik.
