Background

Container intermodal is an important component of railway modern logistics, and the current intermodal scale of China is far lower than that of western countries, so that the national logistics cost is far higher than that of developed logistics countries such as the United states, europe and the like. Meanwhile, the railway container handling stations are insufficient in number, and most of the railway container handling stations are small in scale, insufficient in loading and unloading capacity and the like. More importantly, in the freight platform after electrification transformation, because the electric traction system contacts the power grid (a contact net or a high-voltage line), a large number of platforms do not have the capability of directly loading and unloading heavy-load containers. The overhead contact system is generally arranged below 6.5 meters from the track, and conventional loading and unloading equipment such as a container front crane, a gantry crane and the like which need to occupy the space above the vehicle cannot be practically operated. If the container handling station is required to be opened, only the application of dismantling the contact power grid or the diversion line to use the diesel locomotive to pull to a special cargo yard is required, and the defects of long construction period, large investment waste, high operation cost, multiple harm of the ring and the like exist.

Wherein the steering drive wheel assembly 110 is capable of universal wheeled rotation about its vertical axis through the gearless swivel bearing 114, while the fixed combined wheel assembly 120 is not capable of rotation and fixation about its vertical central axis, but by combining the balance beam 122 and the swing support center shaft 123 to reduce the overall machine wave and instability due to running ground road irregularities, an approximately three point support design arrangement can ensure maximum stability and full landing of all wheels.
