The cranes are due at Oakland International Container Terminal on September 14, according to terminal operator SSA Terminals.

At 300-feet-high, they would be the tallest in North America when they commence operations in January, reports London's Port Technology International.

"As ships keep getting bigger, SSA and ZPMC continue to help us keep ahead of the industry," said Port of Oakland executive director Danny Wan. "We're very excited and grateful for the partnership."

The cranes can lift containers 174 feet above the dock, enabling them to stack boxes 12-high on ships. They can reach 125 feet across a ship's deck, spanning 24 rows of containers. They will be delivered by ship and require five days to be transferred from vessel to dock.

SSA placed a US$30 million order for its new cranes in February 2019. In 2018, it completed a project to raise the height of four other ship-to-shore cranes.
