October 31，The world's first 9 axles 4000 tonsDelivery of all-terrain craneZhejiang Hopson Hoisting Engineering Co., Ltd.，This is the only one in the world.Maximum lifting capacity、Minimum number of axesA wheeled crane，Combination of powerful performance and flexible construction。

For crane research and development，The most difficult thing is not to improve the lifting capacity.，Instead, it improves performance while keeping the chassis size as large as possible.。SAC40000TBreak through the limit of bearing capacity of traditional 9-axle crane，Achieve the most compact of the same ton、Minimum turning radius，It is another breakthrough in the field of innovation for Sany super-large tonnage crane.。
