Replacement of Rail Car Dump #2 and Take-Away System

Railcar Dumper #2 System (RCD2): a. Alabama State Port Authority (ASPA / Owner) is planning to replace and/or modify the existing equipment and components making up the #2 train unloading system (Project), located on McDuffie Island, in Mobile Alabama (Site). b. Railcars currently deliver unit trains of primarily metallurgical and on occasion thermal coal to the Site to be unloaded and transferred to existing storage yards on existing equipment. The new train unloading system will allow ASPA to unload railcars more reliably and efficiently satisfying immediate needs and future production capacity increases. c. The Design/Supply Project consists of two distinctive packages: i. replacement of the Rotary Railcar Dumper #2, Indexer and Wheel Chock Train Holding System (RCD2), and ii. replacement of the receiving hoppers, feeders, collection conveyors, transfer onto the take-away conveyor C-16 and ancillary systems (Take-away System). The Takeaway System is a separate package, excluded from this Specification. d. The new RCD2 System package consists of: i. replacement of the existing double rotary railcar dumper with Tandem Single Rotary Dumpers operating within the existing vault; ii. replacement of the existing cable drawn railcar Positioner (Indexer) with a rack and pinion driven Positioner, and iii. replacement of the Wheel Chock System with a new Wheel Lock System. RCD2 Take-Away System (TAS2): a. Alabama State Port Authority (ASPA / Owner) is planning to replace and/or modify the existing equipment and components making up the #2 train unloading system (Project), located on McDuffie Island, in Mobile Alabama (Site). b.

The RCD2 is a separate package, excluded from this Specification. ii. replacement of the receiving hoppers, feeders, collection conveyors, transfer onto the take-away conveyor C-16 and ancillary systems (Take-Away System, "TAS"). d. The new TAS package consists of: i. redesign and replacement of the four (4) existing take-away receiving hoppers with new hoppers complete with inlet grizzlies, side deflector panels, liners and all associated plate work and support steel; ii. replacement of eight (8) existing vibratory feeders with four (4) apron feeders; iii. replacement of two (2) existing 72" under-hopper receiving conveyors (C22 and C23) with one (1) 96" collection conveyor below the apron feeders.
