The Port of Oakland is planning for the future by preparing for the mega ships and their inevitable calls on US West Coast ports. These behemoth ships require taller cranes in order to reach the top layers of containers on fully loaded ships. So, to be ready, the port has begun work on raising the height of four ship-to-shore cranes by 27 feet.
The process entails removing one crane at a time from service. The crane will be braced while the lower legs are cut, removed and replaced with extensions. The entire process is expected to take nine weeks per crane.
Modern engineering is a fascinating thing.
