RailWorks installed three crane rails and replaced two tracks on Berth No. 8 at the Port of Wilmington.
RailWorks Track Systems worked as a subcontractor to Cape Romain Contracting on the total replacement of Berth 8 at the Port of Wilmington, North Carolina. The port's intermodal lifts operate on the crane rail system to load and unload ships and trucks.
RailWorks installed 1,290 linear feet of 175-lb. crane rail and two 110-lb. railroad tracks totaling 900 track feet, all on an Atlantic Track & Turnout System.
The direct fixation system used in this project consisted of ¾"x12"x10' steel sole plates mounted on anchor bolts on 16" centers. Once plates were set and leveled, RailWorks crews placed steel-reinforced rubber impact pads on the plates, set the rail on the pads, followed by installation of bolts in the upper clips to secure the rail in place.
After checking rail alignment and establishing proper elevation, crews mixed and poured high-strength grout under the sole plates. To close gaps between Berth 8 and the adjoining berths, they installed expansion joints at either end of the rail.
