FuelCell Energy, Inc. needed to assemble extremely large, heavy fuel cell component pieces and solve related vertical lifting problems. PFlow designed a system that incorporates two material lifts.
The first material lift is a screw lift mechanism and lowers a 90,000 lb piece below grade level. The second material lift carries a 20,000 lbs piece, traverses it sideways and then lowers it on top the 90,000 lb piece.
After the two elements are assembled together, the first material lift raises, with a 110,000 lb load, back to grade level for shipping.
