Some new cranes have a 120-tonne load capacity, enabling them to lift up to four 20-foot (6.1 m) or two 40-foot (12 m) containers. Cranes capable of lifting six 20-foot containers have also been designed. Post-Panamax cranes weigh approximately 800–900 tonnes, while the newer-generation super-post-Panamax cranes can weigh 1,600–2,000 tonnes.
Equipment involved in the detailed design includes container cranes which can be identified by mode: Rail Mounted Quay Crane (RMQC) or Ship to Shore (STS) Crane; and inter-modal container transport facilities used for storage areas such as Reach Stackers, Tractor-Trailer Units (TTUs) and Vehicles.

In the discrete problem, the quay is viewed as a finite set of berths. In the continuous problem, vessels can berth anywhere along the quay and the majority of research deals with the former case. In the static arrival problem all vessels are already at the port whereas in the dynamic only a portion of the vessels to be scheduled are present.
Phase 1 - The first phase of the project adds 1,200 ft (365.76 m) of quay to the existing piers, which will then accommodate four modern quay cranes with a rail gauge of 100 ft (30.48 m). This phase finished two months ahead of schedule in late 2004.
A rubber tyred gantry crane (US: rubber tired gantry crane)/ RTG (crane), or sometimes transtainer, is a wheeled mobile gantry crane operated to ground or stack intermodal containers. Inbound containers are stored for future pickup by drayage trucks, and outbound are stored for future loading onto vessels.
A ZPMC rail mounted gantry crane was used in the construction of the British aircraft carrier HMS Queen Elizabeth. Shanghai Zhenhua Heavy Industries Company Limited (ZPMC, Chinese: 上海振华重工(集团)股份有限公司) is a Chinese state-owned engineering company and the world's largest manufacturers of cranes and large steel structures.

Side-view of Super-PostPanamax portainer crane at the APM Terminal in the Port of Rotterdam. A gantry crane is a crane built atop a gantry, which is a structure used to straddle an object or workspace. They can range from enormous "full" gantry cranes, capable of lifting some of the heaviest loads in the world, to small shop cranes, used for ...
