SafeRack, LLC: This company offers its redesigned, patent-pending Safe-Rack G4 Gangway. The G4 uses cutting-edge metal-stamping technology to create a stronger gangway that is at the same time lighter and smoother to operate. Traditional gangway design features parts that are made of galvanized steel or aluminum and then welded together, a construction process that yields heavy gangways that are susceptible to cracked or fatigued welds after prolonged use. This gangway is constructed using parts, most often aluminum, that are stamped out in a tool-and-die process and then formed by bending the metal into the required shape, eliminating the need to weld the pieces together. All Safe-Rack gangways have 90 shared parts that fold or unfold as the gangway is used. The use of the new metal-stamping technology means that the gangways are more reproducible, as well. This reproducibility also yields accurate replacement parts that can be bolted into the original gangway.
