CentrePort needed to raise their cranes to meet increasing vessel sizes. Liftech provided a feasibility study for different raise heights and a design of the modifications to raise two 1970 Vickers Hoskins-Paceco container cranes by 6 meters (20 feet). Liftech also designed a jacking frame for the contractor that allowed them to raise the cranes in less than a week.
