Xu Zhenchao
An ordinary enough position - crane driver; a monotonous enough job - lifting goods from the dock to a car, ship, or from
Cars and boats are hoisted to the dock. 30 years passed quietly like this. However, people say that for the past 30 years, what has flowed out from this ordinary console he has been holding on to for 30 years is not monotonous notes, but gorgeous movements.
He is the crane driver of Qingdao Port, a bridge crane expert with only a junior high school diploma, and a man who set the new world container handling record twice in one year - Xu Zhenchao.
"You can't just use your strength to work, but also use your brain; to do a job, you must love it and be good at it."
In 1974, after graduating from junior high school, Xu Zhenchao went to Qingdao Port to work. a dock worker. He operated the most advanced lifting machinery at the time - the gantry crane. Xu Zhenchao studied hard and practiced hard. He learned it in 7 days and was the first among the workers who studied together to operate independently.
However, it is easier to hold a meeting than to hold a meeting. When the master opened the door, the hook was lifted smoothly and the wire rope followed a "single line";
When it was in Xu Zhenchao's hands, the hook was unsteady and the wire rope was shaking. Especially in the operation of loading ore onto a train, when a hook of goods is put down, more will be spilled outside the train than inside. Seeing the workers busy cleaning with shovels, Xu Zhenchao felt very guilty.
Also, if too much ore is loaded onto a train, workers will have to work hard to remove the excess; if too little is loaded, tons will be lost and the owner will quit.
In order to master this technique as soon as possible, Xu Zhenchao stayed in the car to practice stopping and stabilizing the hook after each operation was completed and others took a break. Four or five months later, the wire rope of the door operator he opened was running in a straight line. A hook of ore was lifted up and dropped steadily. No more, no less, just enough to fill a wagon. This unique skill of "one hook" was quickly spread by everyone.
Once, Xu Zhenchao was loading dry bulk grain into a train and found that the grain particles were small and easier to spill. In his spare time, he hoisted a bucket full of water and practiced walking the hook until he could move the hook without spilling water. Then load the bulk grain, grab it and push it down, from the cabin to the car smoothly, another unique skill - "clear with one hook". Xu Zhenchao's work is clean and tidy, which greatly reduces the secondary labor of the stevedores, and everyone is willing to work with him.
In 1984, Qingdao Port established a container company, and Xu Zhenchao became the first bridge crane driver. Xu Zhenchao is delving into it again
. There are high and low speed deceleration zones in bridge crane operations. If the deceleration is too early, the loading and unloading efficiency will be reduced, and if the deceleration is too late, it will affect the safety of the goods.
So, he took a test watch and tested it repeatedly, and finally successfully adjusted the deceleration zone to the optimal position. In the past, a bridge crane could lift 14 or 15 boxes in one hour. After the reform, it can lift nearly 20 boxes, increasing the operating efficiency by 1/4.
Once, a heavy fog forced the entire terminal's loading and unloading operations to stop, and the fog still lingered until noon. The captain of the freighter found Xu Zhenchao angrily and asked to unload the container immediately. It turned out that the ship was loaded with refrigerated containers. Unexpectedly, the power supply failed. If they were not unloaded, once the temperature in the containers rose and the goods deteriorated, the loss would be millions of yuan.
A bridge crane is as high as a dozen floors, and the four keyholes used for lifting the container are each no bigger than a bar of soap
Small. The driver is on a bridge crane more than 40 meters high, and has to accurately insert the four claws of the spreader weighing more than ten tons into the keyhole of the container
It is not that easy to operate in good weather, let alone large The fog is thick.
People who are skilled in art are bold. Xu Zhenchao gritted his teeth and agreed. He arranged two experienced operators on the ship and on the shore to report the location of the container at any time through the intercom. He boarded the bridge crane himself and operated it carefully. Following the clear report from the ship and the shore, each box was hooked into place and all were unloaded smoothly. With his excellent kung fu and skillful skills, Xu Zhenchao broke through the restricted area of ??foggy weather operations and saved huge losses for his clients.
In 1991, Xu Zhenchao became the captain of the bridge crane team.
During his work, he found that 60% of bridge crane failures were due to spreader failures, and the failures were mainly caused by the collision between the spreader and the container due to the speed of lifting and falling too fast. He pointed out that such an operation would not only cause the bridge crane to malfunction, but also make the cargo unsafe, and it must be done silently.
The drivers were shocked when they heard this. "Containers are made of iron, ships are made of iron, and trailers are also made of iron. The loading and unloading of containers is like iron touching iron. How can it not sound?" The truth is hard to say, but it is not said. The truth is even stronger: the bridge crane team works on a piece-rate basis. Each more box you lift will earn you an extra amount of money. Do silent operations, handle them with care, and don’t know if you need to reduce the speed and reduce your income?
Xu Zhenchao didn’t explain much and started practicing by himself. By controlling the angle between the horizontal running speed of the trolley and the vertical lifting and lowering of the spreader
, he scanned the corners of the container upwards with his eyes, glanced downwards at the loading position on the ship, and held the joystick to change the speed.
Look for the vertical line. With just a glance, you can locate it accurately, it's light and stable. Then, he specially compiled the operation essentials, personally
trained the backbone and promoted it to the whole team, convincing people with facts. In this way, "silent operation" became Xu Zhenchao's masterpiece and the original creation of Qingdao Port.
In November 1997, Laogang District transported a batch of highly toxic and dangerous chemicals. Once this type of cargo collides, it may
cause a serious accident. In order to ensure safety, armed police and firefighters were deployed at the docks and railway lines, and the entire line was under martial law wearing chemical protective suits. After the ship docked, under the command of Xu Zhenchao, the bridge crane drivers who were skilled in "silent operation" worked carefully
and in one and a half hours, 40 containers were unloaded quietly. And loaded onto the train quietly. The shipowner's representative said with emotion: "Your work is so smooth, it's amazing!"
"We can't be scientists, but we can be skilled craftsmen."
Xu Zhenchao, who became the captain, wanted to do more besides driving his own bridge crane.
Once, the control system of a bridge crane in the team broke down, and engineers from foreign manufacturers were asked to repair it. The expert worked for 12 days and earned 43,000 yuan at once. This incident deeply hurt Xu Zhenchao. He thought, if he could repair it, wouldn't he save money?
Wouldn't he save money?
However, the structure of the bridge crane is very complex, involving six subjects such as electric drive and automatic control. Even if you study hoisting machinery
College students majoring in hoisting machinery will need at least two or three years. Only then can general faults be handled. Xu Zhenchao only had a junior high school education, but in order to
conquer this technology, he studied obsessively, and finally found that all the technical difficulties were concentrated in a piece of control system templates
, and this is the cutting-edge technology that foreign manufacturers are fully protecting - not only are they not provided with circuit template drawings, but they are not even provided with the most basic data
.
Xu Zhenchao does not believe in evil. After work every day, he took the borrowed spare template and plunged into his hut. A
book-sized template has thousands of electronic components densely inlaid on one side, and winding printed circuits on the other side. Such a template is placed on a bridge crane. There are 20 yuan per pound. In order to distinguish the looming lines as thin as hair, Xu Zhenchao specially made a bracket out of glass, placed the template on the glass, placed a 100-watt light bulb underneath, and used strong light to make the template /p>
The invisible lines are revealed and then drawn into a picture one by one. It's troublesome enough just to distinguish these more than 2,000 solder joints.
It's even more troublesome to figure out the connections between them. There may be 4 connecting lines around a point, and each connecting line
extends two connecting lines, and the two connecting lines become 4, and the maximum becomes 20 or 30 connecting lines. Xu Zhenchao used a multimeter to test every point and every line. He often had to test hundreds of electronic components on a line until he finally found a path.
The way is coming. Such delicate work was very tiring for the eyes, and he was so tired that he could not see clearly. Xu Zhenchao went to the refrigerator and took out ice cubes and applied them for a while. Then I started working again, and kept doing it for more than 3 hours every night.
In this way, Xu Zhenchao spent a full 4 years, pushed back 12 circuit templates in one go, and drew more than two feet of circuit drawings
Finally, he conquered the problem overcome technical difficulties. This set of template drawings later became a technical manual for bridge crane drivers and a "sharp tool" for troubleshooting and improving efficiency of Qingdao Port's container bridge crane. Once, a core template on an axle crane was broken. Xu Zhen
Chao went to an electrical appliance store and bought a motion controller for 8 yuan. When he came back, he replaced it with the rear axle crane and it worked normally. But before
it would have cost 30,000 yuan to replace a template!
In 2000, the team’s six tire crane engines were due for overhaul again. Xu Zhenchao found the company leader and asked him to organize the technical backbone to complete the project. First, he would train the team, and second, he would save money. Faced with the complex maintenance process, he and the research team pondered and practiced together, worked overtime, and completed the overhaul of the tire crane engine ahead of schedule. In recent years, the repair projects he has overseen have saved Qingdao Port a total of more than 8 million yuan.
Xu Zhenchao’s maintenance skills were well-known, and the company rewarded him with a pager. Xu Zhenchao’s pager was on 24 hours a day
As long as the bridge crane was faulty, it would be on call. Come, practice as you go.
After mastering the technology of bridge repair crane, Xu Zhenchao is still not satisfied. Because once a sudden failure occurs in the bridge crane during operation, if it cannot be eliminated in time, it will have a serious impact on the loading and unloading efficiency and the interests of the shipowner. Xu Zhenchao proposed a new goal - "Troubleshooting in 15 minutes". He started by dissecting each operating unit and continued to explore, and finally he had a clear idea and could cure the "disease" at his fingertips. At present, the time from the bridge crane team receiving the fault information to the arrival of the engineer in charge to troubleshoot the problem has been shortened to less than 15 minutes
"In the final analysis, modern large-scale production requires teamwork most. Just by myself, I can hammer in a few nails."
2001 In 2019, Qingdao City and Qingdao Port Group implemented the strategy of moving foreign trade containers westward and started the construction of Qianwan Container Terminal
. However, due to various reasons, there was still no major progress in the installation of the bridge crane until late November. At the critical moment, Chang Dechuan, President of Qingdao Port Group, announced the appointment on the spot: Xu Zhenchao was appointed as the general commander of the bridge crane installation, and the bridge crane installation will be completed before the end of the year.
After taking over the task, Xu Zhenchao did two things: first, he called his wife to tell her that he would not be able to go back for more than a month from now to the end of the year
to reassure her; second, he bought the 10 boxes of instant noodles were thrown at the scene.
Qianwan Terminal was still a wasteland at that time, and the on-site office was located in a container on the construction site. The weather is minus ten degrees Celsius
It is equally cold inside and outside the container. Every morning the water in the basin froze into ice, and I had to stamp on it for a few minutes before putting on my work shoes.
You have to go three miles away to eat, and if you miss it, you can only eat instant noodles and cold steamed buns; you sleep in the corner of the container
Put a cardboard box and a coat on it. One time, Xu Zhenchao had a fever that wouldn't go away for several days. His body felt like it was falling apart and he could walk without feeling.
But when I called home at night, I still said the same thing: "The project is going well, and I am fine."
His wife Xu Jinwen and his daughter Xiaoxue were worried and took the ferry to the pier. Visit Xu Zhenchao. His eyes were full of blood and there was a cut on his mouth. There are only two iron containers in the desolate open space of Qianwan Wharf. One of them is Xu Zhenchao's office and bedroom. There are three "inheritances" in it: an electric kettle, a military coat, and a cardboard shell. With tears in his eyes, his wife said, "How can your body bear such pain?" Xu Zhenchao smiled and said, "You won't feel the pain if you do what you like
in your heart."
After more than 40 days of hard work, the super-large bridge crane weighing 1,300 tons, 150 meters long, and 75 meters high finally stood on the wide pier of Qian
Qianwan. Xu Zhenchao and his co-workers shed tears with excitement. However, Xu Zhenchao's rheumatism worsened, and his left leg often did not dare to strain when he started walking. Until now, I have to put on thick woolen socks every night when I go to bed.
With the smooth progress of the port's westward migration strategy, an idea became stronger and stronger in Xu Zhenchao's mind: improve loading and unloading efficiency
and create a world record for container loading and unloading!
On April 27, 2003, the new terminal of Qingdao Port was brightly lit. Xu Zhenchao and his co-workers began to set a world loading and unloading record on the "Mediterranean Alessia
A" sprint. 20:20 minutes, 8 bridge cranes lined up beside the 320-meter-long giant ship. Almost at the same time, the 8 containers on the ship were gently picked up by the bridge crane and put on the trailer. The large trailer carried Containers run back and forth on the dock
. The big clock installed on the bridge crane recorded this exciting moment. At 2:47 a.m. on April 28, after 6 hours and 27 minutes of hard work, all 3,400 containers on the ship were loaded and unloaded. Xu Zhenchao and his workers set world records of a single machine efficiency of 70.3 natural boxes per hour and a single ship efficiency of 339 natural boxes per hour. Five months later, he led his team to increase the record of 339 natural boxes per hour for a single ship to 381 natural boxes per hour.
Qingdao Port's container brand of "10-hour ship completion and guaranteed shift" makes this record even more shining, and its "super efficiency" is famous in the international shipping industry!
Xu Zhenchao always said modestly: "Loading and unloading efficiency is the result of collective collaboration. In the final analysis, modern large-scale production requires teamwork most
. Just by myself, I can make a difference." Iron can drive a few nails." Over the past few decades, Xu Zhenchao has created many unique skills and has also led a team that can do unique skills and innovate. Now, many loading and unloading experts like him have emerged in the team. Many technical supervisors have successfully presided over the electronic control transformation of many bridge cranes, and the maintenance class of the bridge crane team has also improved
The replacement method of the bridge crane wire rope greatly shortens the time for changing the wire - this time is the shortest among coastal ports in the country.
What excites Xu Zhenchao and his bridge crane team even more is that "Zhenchao Efficiency" has produced a huge brand effect, and Qingdao Port
is becoming more and more famous in the world shipping market high. Over the past year, many well-known shipping companies at home and abroad have taken the initiative to seek cooperation with Qingdao Port. They have launched routes, increased flights, and increased container volume. In just 8 months, Qingdao Port has recorded a net
13 international routes have been added, achieving global connectivity. In 2003, the container throughput was 4.2 million TEUs, achieving a rapid growth of 24.3%.
While interviewing Xu Zhenchao at the bustling and busy Qingdao Port Terminal, this simple "old pier" pointed at the bustling cargo ships on the sea and said a very simple sentence : "The goods move fast and well, and we feel at ease."
Xu Zhenchao's "unique skill"
Xinhua News Agency, Qingdao, April 12 (Reporters Liu Haimin and Lin Hongmei ) If you hadn’t witnessed it with your own eyes, you would never believe it
Xu Zhenchao’s “silent operation” would be so magical. The foreign crew members said it was "unbelievable" that such a large container was put into a ship or car made of iron, and it actually made no sound
The iron touched the iron, but the Chinese dock worker Xu Zhen was beyond imagination
< Did it like a p>.This is a "unique skill" of Xu Zhenchao. In fact, he created this operation method because it can
reduce the wear and tear of containers and ships to the greatest extent, especially It is to reduce the failure rate of bridge crane 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 carried a batch of highly toxic chemicals that were unloaded at Qingdao Port and exported from Alashankou, Xinjiang.
Dangerous goods, this type of cargo is particularly afraid of collisions , a slight collision may cause a serious accident. At that time, relevant leaders of the Ministry of Railways, ship owners, and cargo owners rushed to the dock. To ensure safety, armed police and firefighters were deployed at the docks and railway lines. Calm
The composed Xu Zhenchao and his teammates showed off their "unique skills" at the critical moment. In just one and a half hours, 4
0 containers were quietly unloaded from the ship and loaded onto the train without a sound.
Faced with this operation that was as easy as "flowing clouds
water", the ship owners and cargo owners who had been nervous for a long time burst into cheers.
Xu Zhenchao is an innovative explorer. His understanding is very simple: I cannot be a scientist, but I can have a unique skill
. These "unique skills" can make me a skilled craftsman, which is what the times and the port need.
With such a belief, Xu Zhenchao has more and more "unique skills" in his "technical pocket".
"One hook for accuracy" was created by Xu Zhenchao when he was working on the door operator in the early 1970s. There are 4 keyholes on the container.
It is difficult to distinguish them from a bridge crane tens of meters high, let alone lower them with a spreader swinging in the air and lock them all at once
The eyes are aligned and the container is firmly grasped. However, Xu Zhenchao and his teammates did it. The secret to Xu Zhenchao's practice of "one hook is accurate" is that the hook head is lifted smoothly and the wire rope follows "one line". His great apprentice Zhang Xianxin operated with ease and accuracy. He smiled and said: "It took me a year of practice to get it right."
"One hook net" is another invention of Xu Zhenchao. Drivers who drive cranes in Qingdao Port all know the "four stability" formula: the hook should be stable when lifting the hook in the cabin, stable when rotating, stable when dropping the hook, and stable when changing the amplitude. . But it is not easy to coordinate these four aspects
. Especially for the drop hook, improper operation will cause the goods to leak. How can we prevent the goods from spilling
? Xu Zhenchao started practicing. After practicing for half a year, he was able to hook the spreader without releasing it at all. He named this technique "One Hook Clean". When grabbing grain, the grab bucket of the spreader weighs 10 tons. It is not easy to accurately load the 10 tons of grain
into a carriage that is 12.5 meters long and 2.7 meters wide. Because the crane's grab bucket extends to 3.4 meters, which is wider than the carriage. Xu Zhenchao practiced repeatedly, wondering how wide the mouth of the grabber should be, and finally found the right size. When transporting grain by railway, the loading standards are very strict. The grain must be pointed in the carriage, 80 cm above the carriage. The dock workers call it "keel". It is difficult to build this "keel". The slope must be appropriate, the slope surface must be smooth, and it must be covered with a tarpaulin to prevent rainwater from being stored. Xu Zhenchao solved these problems with his "one hook net".
The "secondary stop hook" invented by Xu Zhenchao has now been widely used by bridge crane drivers. He found through statistics that the most common safety problem in bridge crane operations is when boxes are dropped together. In order to avoid similar problems, he
required each driver of the bridge crane team to do a "second stop hook" when lifting the box, that is, when the box just left the ground and was about to land
For a moment, slow down, observe first and then rise and fall. Although this adds a few seconds to each operation, it eliminates hidden dangers
and ultimately improves production efficiency.
Another "unique skill" of Xu Zhenchao is "fault-free operation". Combined with the actual situation of Qingdao Port, Xu Zhenchao proposed a "one, two, and three" working method for core liner shift maintenance operations. "One" means "one goal": the bridge crane appears without reason
trouble-free operation; "two" means "two systems": for all on-shift operations, the first is the day and night duty system for technical supervisors, the second is the 15-minute troubleshooting system for sudden failures; the third is the "three "Beforehand": For bridge cranes, the technical supervisor should perform maintenance before maintaining the shift operation
First, master the ship's technical information and operating container volume in advance, and mobilize in advance. Their hard work paid off, and they achieved their goal of ensuring trouble-free operation of the class. Afterwards, they took the lead in achieving the goal of "100% guaranteed availability of all core liners" in coastal ports across the country.
Workers say that Xu Zhenchao is capable of thinking and thinking. After the promotion of the "unique skills" he created, he created new advantages for Qingdao Port
and also led the workers to innovate. Interest and enthusiasm.
my country’s dock worker Xu Zhenchao’s team sets a world record for container loading and unloading
Xinhua News Agency, Beijing, April 11 (Reporters Lin Hongmei and Liu Haimin) my country’s Qingdao Port Qianwan Container Terminal Company
>The bridge crane team, headed by Xu Zhenchao, has achieved a terminal loading and unloading efficiency of 381 natural boxes per hour, which was recently recognized as the latest world record by the Ministry of Transportation
.
According to the relevant person in charge of the Ministry of Transport, after repeated verification by the Ministry of Transport and communication with world authoritative organizations, it was confirmed: 2
On September 30, 2003, the crane of the Xu Zhenchao Bridge was During the operation of receiving and unloading the "Mediterranean Alesia", the container handling efficiency of 381 natural boxes per hour was created, setting a new record for container handling in the world.
In October 2003, the authoritative magazine "Ports and Harbours" in the world's shipping industry published a world record of 381 boxes set
by Xu Zhenchao's team. The world-famous shipping company Mediterranean Shipping Company wrote a special letter to Qingdao Port to express its congratulations.
In addition, on March 4, 2002, the bridge crane team headed by Xu Zhenchao was loading and unloading cargo on the British Railways "Tommy
Sailboat". With a single-ship efficiency of loading and unloading 299.7 natural containers per hour, it broke the highest record for container loading and unloading in mainland China;
On the night of April 27, 2003, Xu Zhenchao’s team was picking up During the loading and unloading operation of the "Mediterranean Famia" ship,
with a single ship efficiency of 339 natural containers per hour, the world's highest container loading and unloading record was set for the first time. The previous record
was set by Hong Kong Modern Container Terminals on February 1, 2001, with a single ship efficiency of loading and unloading 336 containers per hour
.
Qingdao Port (Group) Co., Ltd. named this world efficiency "Zhenchao Efficiency" after Xu Zhenchao, captain of the bridge crane team.
Qingdao Port was founded in 1892 and is my country's largest 100-million-ton port. It was completed in 2003.
Container throughput ranks third among Chinese ports.
