The invention discloses a marine travelling crane relating to the technical field of manufacturing of the marine travelling cranes. The marine travelling crane comprises two guide rail beams provided with longitudinal guide rails, a travelling crane transverse beam which moves on the two longitudinal guide rails through walking wheels, and hoisting winch systems arranged on the travelling crane transverse beam, wherein racks are arranged at the bottoms of the guide rail beams; each of the two ends of the travelling crane transverse beam is at least provided with one walking small gear driven by a motor; the walking small gears are engaged with the racks; a synchronizer is arranged between the racks at the two ends of the travelling crane transverse beam; and the travelling crane transverse beam is provided with the two hoisting winch systems. Compared with the prior art, the marine travelling crane has the advantages that the problems that the hoisting accuracy and the hoisting reliability of an existing marine common travelling crane are poor can be solved.
