This crane is specially used for loading, unloading and stacking 20ft, 40ft and 45ft international standard containers in railway loading yards. This machine is equipped with a telescopic container spreader, which is used to lift containers of various specifications. The opening, closing, blocking and telescoping of the spreader is controlled by the driver from the control room. At the same time, in order to adapt to different container stacking directions and container trailer moving directions, the container spreader can be equipped with a rotating mechanism, which allows the container to rotate randomly to improve loading and unloading efficiency.
