Seaport Container Scanner uses LM76
OSG 40 Rails and Roller Blocks.
"On January 4, 2007, Congress
passed the Implementing Recommendations of the 9/11 Commission Act.
Included in the bill's provisions was a mandate that the Department of
Homeland Security (DHS) scan 100 percent of maritime cargo entering the
United States by 2012. Given the fact that approximately 11.6 million
cargo containers enter U.S. ports each year, this mandate could cripple
the ability of the private sector to move goods on time." The mandate is
to deploy a system that can rapidly scan containers without creating
bottle necks. This system is now available.
"There were several challenges we had to overcome - none more pressing than the ability to stand-up to the salt air/spray environment. We had to take a system that is not all-weather and make it all weather. Not easy when you have sealed rollers that are steel running on a steel shaft. We had to choose a system that would offer low friction, tolerate contamination and not rust away. Looking over all our products, we chose the OSG roller Block/Rail assembly as our base system: https:/www.lm76.com/speed_rail_osg.htm
According to company President John Tarbell: "Each rail is 24 feet long and poses it's own challenges. We did not want to butt joint rails because the mounting surface is less than flat. If we employed rails that required butt joining - due to the overall length of the rails - we could experience very rough transition points that could negatively affect the life of the bearing block rollers. The LM76 OSG system allows us to construct almost unlimited rail lengths."
As shown, the OSG rail is a
two piece rail that allows you to stagger shafting from 1 section to
another so you can avoid butt joining. This makes for very clean
transitions from rail to rail.
Resulting properties from these
chemical and structural composition changes are increased
Next, to protect the rollers
from corrosion we chose an enhanced surface treatment that encapsulated
the roller, pin and the sealed
