Qingdao celebrity composition, urgently needed.

Xu Zhenchao, born in 1950, graduated from junior high school and has been working in Qingdao port since 1974. He has successively won the titles of Qingdao Model Worker, Qingdao Excellent party member, Shandong Excellent Worker Technician, Provincial Self-taught Advanced Individual, National "May 1st" Labor Medal Winner, National Traffic System Model Worker and National Excellent party member. , known as the outstanding representative of industrial workers in the new period.

Xu Zhenchao's "silent operation" put a huge container into an iron ship or an iron car, which actually realized that iron would not make a sound when it touched iron. This is a stunt of Xu Zhenchao. In fact, he created this operation method, because it can minimize the wear and tear of containers and ships, especially reduce the failure rate of bridge cranes and spreaders, and improve work efficiency. Practice has proved that it is the most scientific and reasonable.

One year, the old port area of Qingdao Port left Alashankou, Xinjiang with a batch of highly toxic and dangerous chemicals unloaded from Qingdao Port. This kind of goods are particularly afraid of collision, and a slight collision may lead to a vicious accident. At that time, the relevant leaders of the Ministry of Railways, shipowners and shippers all rushed to the dock. In order to ensure safety, armed police and firefighters have been sent to docks and special railway lines. Poised, Xu Zhenchao and his teammates showed their unique skills at the crucial moment. It only took an hour and a half, and 40 containers were quietly unloaded from the ship and loaded on the train without saying a word. In the face of this easy "flowing" operation, the owner and shipper who have been nervous for a long time cheered.

Xu Zhenchao is an innovative explorer, and his understanding is simple: I can't be a scientist, but I can have a skill. These "unique skills" can make me a skilled craftsman, which is what the times and ports need. It is with this belief that Xu Zhenchao has more and more unique skills in his "technical pocket".

"A hook is accurate" was created by Xu Zhenchao when he opened the door in the early 1970s. There are four lock holes on the container, so it is difficult for Xu Zhenchao to tell them from a bridge crane several tens of meters high, not to mention putting down the sling swinging in the air, aiming at all the lock holes at once, and holding the container tightly. However, Xu Zhenchao and his teammates did it. The key to Xu Zhenchao's "one hook is accurate" is that the hook is stable and the wire rope is "one line". His great apprentice, Zhang Xianxin, is handy and accurate in operation. He smiled and said, "I practiced 1 year."

"One hook and one net" is another invention of Xu Zhenchao. Drivers who drive cranes in Qingdao Port all know the formula of "four stabilities": steady hook lifting, steady rotation, steady hook dropping and steady amplitude changing. But it is not easy to coordinate these four aspects. Especially if the hook is dropped, the goods will be leaked due to poor operation. How can we prevent the goods from overflowing? Xu Zhenchao began to practice. After half a year's practice, he successfully hooked the spreader and never gave up. He named this technique "a hook net". When catching grain, the weight of spreader and grab bucket is 10 ton. It is not easy to accurately load this 10 ton of grain into a carriage with a length of 12.5 meters and a width of 2.7 meters. Because the grab bucket of the crane extends 3.4 meters, which is wider than the carriage. Xu Zhenchao practiced repeatedly, trying to know how big the mouth of the grab was, and finally found the right size. When transporting grain by railway, the loading standard is very strict. The wood grain should be pointed in the carriage, 80 cm higher than the carriage, which the dockers call "keel". It is difficult to hit this "keel". The slope should be appropriate and gentle. Only when the tarpaulin is covered can it not rain. Xu Zhenchao solved these problems with his "one hook net".

The "second stop hook" invented by Xu Zhenchao has been widely used by bridge crane drivers. After statistics, he found that the most prone to safety problems in bridge crane operation is when the boxes fall together. In order to avoid similar problems, he asked every driver of the bridge crane team to make a "second hook stop" when lifting the box, that is, when the box just left the ground and was about to land, slow down and observe first before taking off and landing. Although this makes the operation time more than a few seconds, it eliminates the hidden danger of accidents and finally improves the production efficiency.

Another stunt of Xu Zhenchao is called "trouble-free operation". Combined with the reality of Qingdao Port, Xu Zhenchao put forward the working method of "one, two, three" for core liner transfer, in which "one" means "one goal": the bridge crane runs without fault; "Two" means "two systems": one is that the technical supervisor is on duty day and night, and the other is that there is a sudden failure 15 minute inspection system; Third, "three things in advance": for bridge cranes, the technical supervisor should overhaul them in advance before the shift operation, grasp the ship's technical data and the number of operation boxes in advance, and mobilize them in advance. Hard work pays off, and they realize the goal of trouble-free operation of the class. After that, they took the lead in achieving the goal of "all core liner classes 100% guarantee" in coastal ports across the country.
