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.
[1] Advantages:its mobility gives a rubber tyred gantry crane wide appliance Being mobile, RTGs are often powered by diesel generator systems (gensets) of 100 to 600 kW (134 to 805 hp). Due to the lack of an electrical grid to dump energy when containers are being lowered they often have large resistor packs to rapidly dissipate the energy of a ...
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.

As container ships usually have no on-board cranes or other mechanism to load or unload their cargo, they are therefore dependent on dockside container cranes to load and unload. However lift-on/lift-off vessels can load and unload their own cargo ...

The smaller cranes start at around 50 tons [which?] in lifting capacity, with the largest being able to lift 20,000 tons. The bigger sheerlegs usually have their own propulsion system and have a large accommodation facility on board, while smaller units are floating pontoons that need to be towed to their workplace by tugboats .
