"Get ready to unload! The 10000 ton freighter from the Philippines is about to dock." Chen Zujun, Manager of Tieshangang Operation Area of Beihai Wharf Co., Ltd. of Guangxi Beibu Gulf Port, stood in the dispatching room, staring at the monitoring screen, holding the walkie talkie, and busy dispatching and commanding. Tieshangang is still busy at night. Nearby, freighters shuttle and "giant arms" dance; In the distance, the lights of cargo ships twinkled with the stars in the sky. Several large freighters are berthed on the shoreline of Tieshan Port Public Wharf. More than 20 unloading machines that have just received the unloading instruction line up on the shore, waving their swinging arms and grab buckets, and began to load and unload with great enthusiasm. Huang Guan, the "post-90s" driver, is skillfully controlling the joystick in the cab of the unloader more than 20 meters high. With the help of the visualization system, a bucket of goods weighing about 10 tons was unloaded in only 2 minutes. "This machine can handle about 20 containers in an hour. Six years ago, when I first worked, it was an advanced equipment. Now, the efficiency of the new equipment in the port area is 50% higher than this." Huang Guan said with emotion, "Tieshangang is really like a year!" The flow of goods is smooth and busy. As one of the important sea going hubs of the new land sea channel in the west, the cargo throughput of Tieshan Port increased by 33.18% from January to August this year. "This puts forward higher requirements for unloading efficiency. We are working day and night to seize the second to improve quality and efficiency, and to serve the national strategy of the new land and sea channel in the west." Chen Zujun said. By the end of 2021, the cargo throughput of Tieshan Port will reach 26.839 million tons, and the container throughput will reach 409000 TEUs, with an average annual growth of 9.66% and 20.55% respectively in the past four years. Gao Feng, Deputy Manager of Tieshangang Operation Area, pointed to a large storage yard and said proudly, "You see, there are intelligent gates, rubber tyred container gantry cranes and automatic remote control systems. One operator can remotely control two machines at the same time, which greatly improves the efficiency." The night is getting deeper, new energy loaders and dust suppression artillery vehicles are still going back and forth in the port area, and container trucks are heading for the distance... With the flute sound of the sea rail intermodal train entering the port, Tieshan Port ushers in another busy day at 8 a.m. At the railway loading and unloading line of Tieshan Port, He Tengda, Deputy Director of the Railway Office of the General Dispatching Office of Beihai Wharf Co., Ltd. of Beibu Gulf Port, came here early in the morning to coordinate the expansion of the storage yard, and the light blue overalls were already soaked with sweat. In April 2020, the special railway line for Tieshangang port entrance was officially completed and opened to traffic. The railway yard is less than 100 meters away from the coastline, opening up the "last kilometer" of sea rail intermodal transport. Taking the special line from Tieshangang to Guidong as an example, the logistics cost per ton dropped by at least 6 yuan after the opening of sea rail intermodal transport. "Tieshan Port currently has six 150000 tonnage berths, with an annual cargo throughput of 3150
