From the Tacoma Weekly:

The first four super post-Panamax cranes destined for Tacoma’s Pier 4 began the trip to Puget Sound a few days ago aboard the Zhen Hua 28.

The new cranes, built by Shanghai Zhenhua Heavy Industry Co., Ltd. (ZPMC) in China, will be capable of serving ultra-large container vessels with an outreach of 24 containers and a lift height of 165 feet above the pier deck. The cranes are expected to arrive at Port of Tacoma in a few weeks. Four additional cranes will arrive in 2019.
