Cranes 13-14-15-16
These four (4) quay cranes are the second (2nd) order of Super Post-panama cranes placed into service by Port Miami. They were design to have the capacity to work any operational container vessel and on engineers’ drawing boards. They can reach 22 containers across a ship with a 3% list; 23 wide ships with NO list at Port Miami. They were also designed to work over nine (9) high standard cubes stacks on the ships decks. They are fitted with ABB ACS800 MultiDrive System, AC800M Controller with CMS 7; ZPMC gearboxes, Bubenzer brakes, ZPMC 20/40/45/2-20 65LT Twin-Lift Separating Spreaders and run on the 13.2 KVAC shore power. They can also lift 100 LT under the cargo beam (the “Hook”) which give them the capability to lift special slunged cargo. Below are these cranes’ specifics;
