The project is jointly carried out by Shanghai International Port (Group) Co., Ltd. and Zhenhua Port Machinery Co., Ltd. and Shanghai Jiaotong University. It mainly includes an automated container intelligent unmanned yard and two efficient double-car RMG (rail gantry crane) containers. Automatic loading and unloading line, and a modern port container logistics intelligent, digital management platform. Since the commissioning of the intelligent unmanned yard on April 23 this year, the industrial production test operation of 21658 TEU has been completed on the 15th of this month.
At the acceptance site yesterday, the reporter saw that a card was opened to the intelligent unmanned crossing of the dock. The driver stopped to reach out from the window, got the automatically printed ticket, and then drove the car to the address on the ticket. The destination stops, and then you just have to "stand by" and wait for the crane to load and unload.
After watching the live demonstration, the well-informed experts said “very excited†in unison! This affirmation stems from the “world's first†created by a series of independent innovations:
A 17-meter-high gantry crane first unloads the container from the set card and places it on the transfer platform. Then another 34-meter-high gantry crane is lifted from the transfer platform and placed in the yard. Loading and unloading operations and yard operations Separate, the card does not enter the stacking area - this "relay" loading and unloading process is the world's first, it will raise the current "heap 4 over 5" to "heap 8 over 9", that is, 8 containers vertically stacked After that, the ninth box can pass from above, which is almost double the current international average;
3D Laser radar plus accurate image processing system to "contour scan" the container, the vertical error from top to bottom is no more than 5 mm - this card automatic positioning and boxing technology is the world's first;
The two-car overhead gantry crane can simultaneously grab and move two 40-foot "large" containers - the double loading and unloading mode is also the world's first.
All of these "world's first" are integrated and are playing the "1+1>2" superposition effect. At present, the container throughput of the entire yard has increased by 20%, and the annual throughput capacity has reached 540,000 TEU. The person in charge of the project, the vice president of Shanghai International Port (Group) Co., Ltd., and the “grab the king†Bao Qifan said: The Shanghai Port terminal is full of gold, this technology can maximize the use of space, and improve the efficiency of loading and unloading, shortening The ship is moored at the port.
It is reported that the project has applied for and obtained more than 20 patents, and the famous ports such as HALLA Port of Germany and Dubai Port of UAE have shown strong interest in this.
