Seneca Steel
was asked to send a crew to Hawaii to do maintenance, repair and
at least one rebuild of stokers at a sugar mill on one of the
islands. We have enough tools and equipment to maintain
at least five crews doing simultaneous projects. We packed
up a container laden with tools and sent some very happy workers
off to Hawaii during an Ohio winter. When they arrived,
they found plenty of work that needed to be done. One of
the stokers had so much damage around the solid fuel feeder chutes
that much of the stoker wall around the chutes had to be cut out
and replaced. 
Many previous attempts
at repairs added to its current condition, but our men were able
to rebuild it to its original strength.
Here are a number of
pictures taken of the three stokers during the repair and maintenance
phase, just to give you an idea of the size of the projects. Seneca
Steel was able to get the job done well within the customer's
timeframe. The pictures are in random order:
