Marine dredge barge cylinders.
These 20,000 pound cylinders
were designed and built to open
and close the split hull of a marine
dredge. Their physical size and
weight required large honing and
machining tools, as well as special
handling equipment. Specific
marine coatings and external seal
arrangements also were necessary.
The cylinders were manufactured
to meet ABS (American Bureau of
Ships) and USCG (United States
Coast Guard) rules of construction.
Cylinders for dumping wood
chips. These three-stage, single
acting, telescopic cylinders were
built for a unique application in
the pulp and paper industry: Lifting
platform and semi-truck trailers to
dump wood chips. The cylinders
required deep hole boring and
honing, and feature a 430" stroke.
Not only did they replace existing
cylinders, but they also dramatically
improved the service life.
