Since the production of marine diesel engines is customized, the manufacturing workshop generally does not set up a separate production line for a certain model, and the main engine model assembled on each test bench is not fixed. Therefore, after completing the assembly and test of the previous main engine, the test bench generally needs to be rearranged before continuing the assembly of the next main engine. At the same time, when testing diesel engines, intermediate bearings, dynamometers, gearboxes and motors are usually required. When testing diesel engines of different sizes, it is necessary to ensure the stable support of the diesel engine, intermediate bearings, dynamometers, gearboxes and motors at the same time, and it is also necessary to ensure the shaft system between the various devices.
