Zusammenfassung: | The invention discloses a quayside container crane, which is provided with two cantilever beams penetrating front and rear upper cross beams and installed on the front and rear upper cross beams. The distance between the two cantilevers is approximately equal to the distance between two adjacent compartments of a ship to be loaded or unloaded, and the width in the direction of the ship length of the boundary dimension of the crane is smaller than or equal to the total width of two adjacent compartments. As the distance between two cantilever beams of the container crane can guarantee that hangers on the two beams are located above the adjacent compartments to be loaded or unloaded respectively, the crane can load and unload the adjacent compartments simultaneously. At the same time, the width of the crane in the direction of the ship length is no more than the total width of the distance between the adjacent compartments, so that two or more cranes can approach to work cooperatively, a plurality of adjacent c |
