In less than 2 minutes, two containers weighing up to 30 tons were transferred from trucks to ships. In the 3 ㎡ operation room on the 8th floor of Zhuhai port wharf, the bridge crane operator has a series of smooth and light operations, such as running clouds and flowing water, sliding a beautiful parabola in the air. He controls one of the four 65t-65m shore bridges delivered to Zhuhai port by SANY offshore engineering last year, which has become the main equipment for bridge crane operation in Zhuhai port.         

"Stable performance and comfortable operation." It is the general feeling of Zhuhai bridge crane master to Sany shore bridge. It is the stability and comfort of the equipment that provide strong support for the rapid growth of Zhuhai port. In 2019, the container throughput of Zhuhai port will reach 2.56 million TEU, with a growth rate of 10.7%.

Winning in "stability": mmbf is far ahead      

According to Sany Offshore Engineering Research Institute, Sany quayside bridge adopts three-dimensional digital platform design to realize the full parameterized associated drive design of structure and mechanism, which can not only shorten the design cycle, but also make the design more reasonable through automatic selection and virtual assembly, so as to reduce failure rate, improve product quality, operation stability and comfort. This makes the mmbf (mean distance between failures) of Sany quayside bridge operating in Zhuhai Port significantly higher than that of other quayside bridge equipment, and even the monthly mmbf of 3099 TEU is recorded.    

"Accurate" to milliliter: greatly improved efficiency      

 Port operation, every minute counts. In order to ensure the efficiency of air positioning, landing and lifting, loading and moving back, Sany quayside bridge is equipped with a card positioning system and an electronic anti sway system, with an accuracy of within ± 100mm, so as to realize rapid positioning and landing and lifting. Among them, the speed of the trolley can be adjusted by detecting the relative angle deviation between the spreader and the trolley, so as to achieve the purpose of stop swing, and the heavy box can be controlled within ± 50mm swing range in two swing cycles. The card location system can accurately locate the card of each working Lane under the quayside bridge, so that it can stop at the lifting position accurately in advance and quickly lift, and the positioning accuracy deviation is not more than ± 100mm.    

"Ruthless" thunder fearless: intelligent lightning protection management  

The weather in the port is changeable, and the clear sky and black clouds often come one after another. Sany shore bridge's intelligent lightning protection system includes five elements of meteorological monitoring, lightning early warning, real-time surge protector status monitoring, recording the intensity, time, times, warning and management functions of lightning discharge current, detailed data for the port to make timely judgment and deployment of operation. The internal electric control management system has more reliable lightning protection measures. The primary, secondary and tertiary lightning protection and surge protection of the main circuit, control circuit and communication configuration ensure the safe use of the equipment.       

Close due to "intelligence": remote monitoring to solve after-sales worries        

In the era of intelligence, Sany shore bridge has realized the global intelligent monitoring of equipment. Technical experts can provide remote technical support to operators and service personnel to effectively improve troubleshooting efficiency and shorten downtime. The intelligent monitoring system also has the functions of equipment data statistics and analysis, installation management, working condition supervision, data storage, etc. to provide data support for equipment maintenance.Sany quayside bridge has become the main equipment of Zhuhai port. In addition to its fast, stable, accurate, safe and intelligent features, it pays more attention to the details, such as the intelligent access control system, which can realize the access control management of boarding personnel and guarantee the safety of human and machine through IC card swiping, AI face recognition and other multiple means. Quality is the basis of Sany's survival. It's the subtle technical details that eventually converge into the huge advantages in the actual operation and create a device that is appreciated by customers. Editor / Zhao Jing
