Heavy Duty Gantry Crane (40t/50t/70t/80t/100t/up to 500t)


Heavy duty gantry crane refers to the cranes which can bear relatively heavier loading capacity compared with the light gantry. Owing high working class, heavy cranes are not only used for handling containers, but also suitable to lift bulk cargoes.

Our factory can produce two types of heavy-duty cranes, they are box-shaped cranes and truss structure cranes. With different structures and designs, they all have their own advantages and disadvantages.

3. The truss structure crane is light in dead weight, and of strong wind-resistance ability.
4. Truss crane is of small lifting capacity, its and its solder joint is not easy for maintain.

40 ton gantry crane is used for lifting goods and materials which weight are not exceed 40 tons, as its name implies. Usually, this weight of cranes are made into double girder type crane for the reason of improving the rigidity and safety.
