These companies cover such diverse bulk handling aspects as equilibrium cranes, conveying systems (including chains) and dome storage.
The increasing cost of US coal and escalating rail freight rated were forcing Progress Energy to find a more economical coal source. Therefore, Atlantic Diving and Marine Contractors developed and built a ship receiving facility to transload the coal from the ships to barges and then transport it upriver to the plants, efficiently unloading it from the barges and moving it by conveyor from the shoreline to the plant.
The E-Crane transfers the coal from barges to an 855ft conveyor system that carries it up to the plant. Because the barges are 52′ wide, 14′ deep and 250′ long, offloading with a traditional hydraulic excavator would be very inefficient. The E-Crane selected for the job (1000 Series, Model 7248) is equipped with an eight cubic yard hydraulic clamshell bucket that can reach out horizontally a distance of 81ft, making it possible to offload the coal from the barges efficiently.
Atlantic has a three-year contract to provide Progress Energy’s Sutton Plant with coal. Progress Energy Carolinas provides electric power and services to 1.3 million customers in North Carolina and South Carolina.
Atlantic Diving & Marine construction company located in Wilmington, NC. E-Crane international-USA, Bucyrus, Ohio, assisted North American Equipment, the E-Crane dealer in Nicholasville, KY, handled the sale, consulted on the specifications and installed the E-Crane. The E-Crane is manufactured in Adegem, Belgium by NV Indusign.
