The energy efficiency and CO 2 emissions of different handling equipment in a container terminal are different (Martínez et al., 2019).The more QCs that are configured, the greater the marginal energy consumption. To reduce the number of QC configurations, the double 40 ft dual-trolley quay crane shown in Fig. 1 is used by some …

A container terminal relies on an array of intermodal equipment to perform its operations, including straddle carriers, gantry cranes, and portainers (ship-to-shore cranes). The choice of equipment and its mix is related to a number of factors in terms of capital investment, volume, stacking density, and productivity. Forklift.

A container terminal's main function is to allow for the transfer of shipping containers and cargo between ships and other modes of transport, such as trucks and trains. Terminals also act as a checkpoint where ships are inspected, loaded and unloaded. You may have heard the terms 'container terminal' and 'container port' used ...

Fig. 1 shows the general layout of a container terminal using RTGCs as YCs, where the container yard is divided into many blocks and owns many YCs. The main function of YCs is to transfer containers between trucks and the stacks of the blocks. Since YCs are very expensive, container terminals generally cannot keep at least one YC in …

Nowadays STS cranes at container terminals operate with a rail span of 30.48 m (100 foot), 35.00 m or even more dependent on the outreach and the operation mode (single, twin and tandem). Some quay wall options, such as deck on piles, allow a rigid connection between crane rails and prevent a possible deviation from the nominal …

Construction of a terminal on a greenfield site mostly involves extending a port on a vacant site along a river, estuary, or coastline. Historically, the majority of port development projects were labeled greenfield, which often goes hand in hand with port migration. The vacant site might be located in a green zone, wetland, or agricultural area.
