The possible future vessel characteristics and related handling operations will put high demands upon infrastructure and superstructure of ports and terminals (Konings, 2008). As vessels expand carrying more cargo port operations must expand as well to compensate for the additional movements. The Eastern ports in the United States cannot expand land area thus they must seek alternatives to transfer cargo. One method to enhance operations while not requiring additional real-estate adaptive crane structures. The Carrier Crane utilizes two waterside trolleys (rope-driven) which position containers onto moving carriers to double hoist cargo during marine port operations (Konings, 2008). Simply the Carrier Crane is two hoist contained in the same structure that would previously suitable for a single crane.
To accommodate double the amount of cargo being moved in limited real-estate areas the interchange area must be located close cargo containers (Konings, 2008). Limiting the distance containers are from intermodal transportation modes improves the potential thru-put and reduces the labor required. If the amount of time from crane to processing area and subsequently intermodal transportation is reduced cargo can move rapidly and enhancing operations. For instance, East Coast ports dominated by the trucking industry gate handling are critical to support the uptick
