ZPMC fabricated the modification components in China and used their jacking equipment to increase the lift height of the cranes on the crane rails in Oakland.
Liftech provided structural engineering services to support Port of Oakland’s review of the crane raise project. Liftech’s services included providing structural specifications for the crane raise and jacking frame, performing an independent analysis of the crane structure for the raise and as-modified for operations, calculating wheel loads to determine if the wharf could support the heavier cranes, and reviewing ZPMC’s crane raise drawings, jacking frame drawings, and fabrication.
