Portage Casting and Mold

In the summer of 2011, Portage Casting and Mold created two 74,000 pound hemisphere molds made of sand and iron.  We placed the molds, contained in custom wooden frames, onto a mobile crib using overhead cranes. Using our Traksporter positioned under one side of the mobile crib, we maneuvered the mold outside, where two cranes picked and rolled the mold.  After turning the cast upside down, the 165-ton and 70-ton cranes placed the frame back onto the mobile crib, which carried the mold back into the building. 

A few weeks later, we returned with two cranes to repeat the steps with the second dome, shaving two hours off our process time.
