Shipyard cranes are the main equipment for manufacturing ships. Currently, crane trolleys generally use rimless wheels and are designed with a guide device (horizontal wheel) added to one side of the track. This structural form reduces the manufacturing deviation and the impact of track gauge changes on the trolley operation under trolley load conditions. Rolling friction replaces sliding friction between the horizontal wheel and the side of the track, and the frictional resistance endured by the operating mechanism is greatly reduced.

The light tire-type container gantry crane for ports can meet the loading and unloading needs of existing cargo types, and has functions such as customs declaration, inspection, foreign trade, and storage. Moreover, its operation efficiency is high and it can take into account the company's subsequent container development. Light tire-type container gantry crane has the following characteristics:

Pastaraisiais metais vis dažniau naudojant offsetines bėgių sijos konstrukcijas (keturkampius plieninius suvirintus bėgius, esančius dėžutės formos pagrindinės sijos viduje), gamybos reikalavimai išaugo. Paimkime šią struktūrą kaip pavyzdį, kad pagerintume ją iš gamybos aspektų, tokių kaip komponentų gamyba ir apdorojimas.
