8 fully automatic tire cranes! Sany empowers the construction of world-class smart ports

2022.01.20

On January 17, Tianjin Port Autonomous Driving Demonstration Zone (Phase II) was unveiled. At the wharf operation site, 8 fully automatic four-rope anti-sway tire cranes transformed by Sany participated in the whole automation operation, contributing Sany wisdom to the world's first port autonomous driving demonstration area.

Since the construction of the world's first port autonomous driving demonstration zone was approved in Tianjin Port, the construction of a world-class smart port in Tianjin Port has been accelerating.

After winning the bid in October 2021, Sany Marine Heavy Industry Co., Ltd. and Tianjin Port Pacific International Container Terminal Co., Ltd. immediately invested in a professional team to carry out in-depth cooperation and technical research, and completed the fully automated transformation of 8 yard bridges within three months, realizing comprehensive improvement in comprehensive operation efficiency, operation safety, fully automatic operation accuracy, spreader anti-sway and anti-torsion.

After the transformation, the Pacific International Container Terminal of Tianjin Port adopts a fully automatic four-rope anti-sway tire crane, and the container trucks in the yard are fully automated, with a comprehensive operation efficiency of 22MOVE/H.

In order to improve the safety of operation, the vehicle sports adopts a self-developed anti-collision system based on monocular or binocular vision, which can detect 15 meters of 50cm*50cm obstacles, provide obstacle location, distance, and image information for on-site verification, and for 3D obstacle information, deep learning can also be used to perform pattern recognition on specific categories such as people and vehicles on 2D images.

At the same time, the lane status detection system based on 3D radar can detect the lane in real time and full coverage, and the accuracy of detecting the features of the container truck is within 2cm.

The use of close-range detection technology and laser scanning recognition technology to achieve the box area and the internal container truck automatic grasp and put box, without manual intervention, Benbei tipping efficiency close to the limit of manual operation 70%.

In addition, the self-developed container bottoming technology with deep learning ability makes the detection accuracy of the box angle line reach more than 99.5%, and the bottoming accuracy is within 3cm, and the bottoming accuracy can be gradually improved through big data deep learning.

Using the four-rope anti-sway and anti-torsion technology of fully intelligent closed-loop control, through real-time anti-sway and anti-torsion of speed following and position following, the swing is stopped within two cycles, and the swing amplitude of the spreader is less than ±50mm.

Through the strong alliance with Tianjin Port Group, Sany has created a "Chinese solution" for port automation upgrades that can be operated, replicated and promoted, enabling the construction of world-class smart ports.
