Shandong Port Qingdao Port promotes dramatic transformation from traditional container terminal to smart green port

Recently, with the completion of the trial operation of the last batch of 14 automated upgraded track cranes of QQCTU, the company has achieved full automation coverage of 91 track cranes in the site, both in terms of speed and scale. They have built a single container terminal with the largest number of intelligent transformations of traditional rail cranes and the longest time in production.

At the beginning of the automation transformation project, QQCTU had no experience to refer to. However, with the strong support of Shandong Port and Qingdao Port Group, QQCTU set up a special class for automation transformation and started to develop automated rail cranes from scratch. Research on the subject of transformation.

The team members did everything possible to collect information and "make up for" the professional knowledge of the automated terminal. They shuttled back and forth between the spreader, electrical room, and trolley frame every day to solve the problem of horizontal rotation and tilt of the spreader. For problems such as excessive angles, the detection range of the spreader rotation deviation is controlled within 2 centimeters, so that the automated rail crane operation can be "accurate in one step" and the container can be grasped stably in one go.

Thousands of streams turn into water and merge into a river. Starting from the "test field" with only three rail cranes in the first phase, to now realizing the automated operation of the entire site, they have gone through a very difficult road of independent research and development, independent transformation, and independent innovation.

QQCTU exports its years of accumulated experience in remote control and automation of rail cranes to accelerate the intelligent construction of automated rail cranes.

From the research on operating technology to the design optimization of the technical solution of the equipment itself, team members tackled difficulties one by one and made breakthroughs one by one. They independently developed the ECS track crane intelligent dispatching system, innovative truck positioning system, Multiple supporting subsystems such as the video stream identification system and the anti-drag protection system have successfully realized the remote "one-to-many" operation of the track crane.

Now, the mechanical efficiency attendance rate has reached 100%, and the single-machine operation efficiency has also increased to 30 per hour Natural box, the team won honors such as "National Outstanding Case of Intelligent Construction Innovation Practice of Transportation Enterprises" and "First Prize for Qingdao Employees' Outstanding Innovation Achievements".

As the high efficiency, high stability and high reliability of automated rail cranes continue to highlight, in 2023, QQCTU refreshed single-shift, day and night loading and unloading throughput production records 25 times, and broke berthing and unberthing 20 times , collection and distribution, single aircraft, route and other efficiency records.

Facing the future, QQCTU will accelerate the promotion of the application of fully automated container terminal intelligent management and control system A-TOS, gradually extend to bridge crane automation and unmanned driving, and create a new era of automation transformation of traditional container terminals. Benchmarks and new highlights.
