The invention belongs to the technical field of test benches, particularly relates to an ocean engineering crane test bench, and aims to solve the problems that an existing test bench cannot be subjected to simple height adjustment, the operation space is limited, the use efficiency of the test bench is greatly reduced, and the simulation progress is influenced. The ocean engineering crane test bench comprises a mounting plate; two vertical plates are symmetrically and fixedly mounted at the bottom of the mounting plate, a placing plate is slidably mounted on the mounting plate, an adjusting device is fixedly mounted at the bottom of the mounting plate, a supporting device is slidably mounted on the two vertical plates, a moving device is movably mounted on the two vertical plates, and a pushing device is slidably mounted on the two vertical plates. Two auxiliary plates are symmetrically installed on the mounting plate in a sliding mode, and the pushing device is movably connected with the two auxiliary plates. The ocean engineering crane test bench is convenient to use, the height can be simply adjusted, the ocean engineering crane test bench can be moved according to needs, meanwhile, the operation space can be enlarged, and the use efficiency is effectively improved.
