This crane is specially used for loading, unloading, and stacking 20, 40, and 45-foot international standard containers in railway freight yards. The machine is equipped with a telescopic container spreader for lifting containers of different specifications. The opening, closing, locking, and retracting of the spreader are operated by the driver in the control room. At the same time, to adapt to different container stacking directions and container trailer travel directions, the container spreader can be designed with a rotating mechanism, which can make the container rotate freely to improve the loading and unloading efficiency.
