Virginia Port Authority (VPA) needed three new cranes for their Portsmouth Marine Terminal. The wharf, with a 50’ rail gage, had limited capacity for supporting gantry cranes of the desired size and capacity. To minimize the wheel load at the waterside rail, Liftech provided engineering services to VPA to assist ZPMC design the cranes with light-weight truss booms.
Liftech’s services included supplying the crane technical specifications, assisting ZPMC with the structural design, fabrication review, seafastening review, and post-delivery commissioning review.
These cranes were the first truss boom dockside container cranes supplied by ZPMC.
