MD2200 Topbelt30塔式起重机专为中国三峡大坝二期工程设计,用于向175 m 高、115 m 宽的三峡大坝浇筑混凝土,放置重达60 t 的金属结构件。该起重机的最大起重能力为60 t,幅度80 m 时起重22.8 t,最大作业高度185 m。起重机上配备了一套由 NipponConveyors 公司制造的混凝土输送系统,以300～400 m~3/h 的生产率将混凝土输送至105 m 距离处。该输送系统由97 m 长、760 mm 宽的橡胶输送带组成,输送带的一端支撑在固定于塔身的平台上,另一端固定在起
The MD2200 Topbelt30 tower crane was designed for the second phase of China’s Three Gorges Dam to be used for concrete pouring to a Three Gorges Dam with a height of 175 m and a width of 115 m, placing metal structures weighing up to 60 t. The crane has a maximum lifting capacity of 60 t and a lifting capacity of 22.8 t at an amplitude of 80 m, with a maximum working height of 185 m. The crane is equipped with a concrete conveyor system manufactured by NipponConveyors to deliver concrete to a distance of 105 m at a production rate of 300-400 m 3 / h. The conveyor system consists of a 97 m long, 760 mm wide rubber conveyor belt with one end supported on a platform fixed to the tower and the other end fixed to
