When the boatman's wife saw that the persuasion was ineffective, she didn't know that she was witnessing a history and cried loudly.

Song Jiu did not care about them, but shouted loudly. Some children were playing in the river bank, and reading was a very distant term for ordinary people. Many children followed their parents to the Bian Dike and played around the Bian Dike. The adults ignored nothing except telling them not to play in the water. Seeing it, the children gathered together.

It was nothing. In order to experiment, Song Jiu worked together to build a similar platform beside the ancient locust tree in his yard. The platform on the Bian Dike was about two meters and five meters high. The platform in his home was only one and a half meters high, and there was no cast iron shaft. Instead, a thick tree branch of the ancient locust tree was used to tie the pulley to measure various data. This was the beginning. If it was used on a large scale, further experiments and measurements were required. The weight was also measured. Eighty stone mud bags and stones were placed in the net pocket to see if the iron wood and iron chains as rotating shafts could withstand it.

The result was safe and sound.

When it was practical, Song Jiu did not expect eighty stones, but floated around fifty stones, and the maximum loading should not exceed sixty stones. Song Jiu has not yet tested how much weight it can withstand, but it can withstand eighty stones. Now it will be very safe to only hold fifty stones.

But to prevent accidents, you must never let anyone stand under it, whether it is a child or an adult. If something happens, five thousand kilograms of goods will be smashed down together and fall on people... I can't even think about it!

The children escaped together amid Song Jiu's shouts, but stood not far away to watch.

It was not only them, but also the coolies on both sides of the river, pedestrians and boatmen put down their work together and looked up to look here.

A few people stood still at the same time, staring at the net bag. A mighty man said to the middle-aged scholar beside him: "Zeping, the net bag contains a lot of ceramics."

Song Jiu was sensational when he lifted it out of his home and had to be installed again, which took a long time to get some big shots to come and watch.

"Yes, it's enough forty or fifty stones."

"Zeping, do you think this thing can be lifted up?"

"I don't know..." The middle-aged scribe shook his head with difficulty.

The chains gradually tightened, and the seventh brother-in-law and Qi Balang still grabbed the rope nervously.

This also has mechanical principles.

There is a long distance from the embankment to the water surface. The trees as the rotation axis are not that long at all. Even if they are that long, Song Jiu dared not. The larger the arm, the larger the curve distance obtained by the same force, the easier it is to break, and on the contrary, the smaller it is.

During some jugglings, the two took out a very long and thick steel bar, shouted loudly to their stomachs, and the steel bar gradually became curved, but try changing to a short steel bar. As long as you train, ordinary people can pay attention to safety and you can do it.

The problem now is that you cannot bend it, so the wood will break sooner or later. So the force arm cannot make it too long. Instead, pull the net bag to the bow of the ship to load, which means that the vertical distance is increasing. Once the chain is twisted, the gravity will inevitably move vertically downward, and it will hit the river bank vertically. Not to mention this net ceramic, it is best not to impact ordinary goods, which will cause rebound and shock and damage the life of the entire crane.

But the power required is not too great.

This is also the principle of mechanics. Gravity and weight have no factors, and are the same. The weight of a fifty stone cargo will have fifty stones downward gravity. But now the chain and the shaft are bearing its weight, which is equivalent to bearing its downward gravity. The seventh brother-in-law and his wife don’t need to be so nervous at all. As long as there is a little force to get it up, the cargo will remain bent in the air until it is vertically distanced from the ground and calmly lower the rope.

A similar truth is to bells.

In some temples, large copper bells can weigh up to a thousand kilograms, but after it is hung, even if it uses ten kilograms of strength, it can sway violently.

The same is true for cargo in the river. A cargo ship worth hundreds of tons often pulls it easily by more than a dozen boatmen. The gravity of the cargo ship has not changed, but the buoyancy of the river water offsets its gravity. The force when the fibre is pulled is not aimed at gravity, but the needle changes the inertia force of the object, and the resistance and friction of the ship breaks through the river water.

They are all simple mechanic principles, including the instrument itself, but if they are explained one by one in this era, it will make everyone feel overwhelmed. Therefore, as soon as it is released, it makes people feel extremely magical.

After the seventh brother-in-law and Qi Balang helped him, the net bag finally rose obliquely from the ship deck to the air.

Seeing it rise, the boat couple did not hide their faces and dared not look at them. The boat girl cried louder and had nothing to do with others, so she stared at them together, and someone exclaimed.

Soon the net bag was vertical to the embankment, and Song Jiu pulled it again, Zhong Dalang and He Erlang pulled the rope on the other side, and turned the wood as the shaft, and the goods came ashore smoothly. One person stabilized the net bag, and Song Jiu and the other two came to help unload the goods from the net bag.

In fact, at the beginning, Song Jiu did not think of the rotation shaft, but directly fixed the wood. But in the end, considering that no matter whether on the embankment or under the river, there must be four people pulling the rope. The rope is in a straight line, and people will save more effort. Once it is twisted, it is equivalent to bending the torque distance, the goods are heavy, and the inertia will be greater. More people must be required to pull the rope. If that happens, the meaning of saving manpower will be lost, so they will come up with the rotation shaft and the wavy circle high platform iron surface.

The four of them quickly dropped the goods, and the seventh brother-in-law pulled the net bag back again. Song Jiu put the iron chain back on the shore and began to prepare for the second time to hang the goods.

"Is this OK?" Boss Hu opened his mouth wide.

Usually, they use their shoulders to carry and unload them, and they must also put them in place. Then they go ashore from the springboard on the boat, follow the river bank from the riverside to the bank, and then go down the river bank to walk back to the boat. It takes a little longer to form a group of goods by pulleys than they do.

However, six people operated it, and it was enough for them to carry twenty or thirty or forty times at a time. And they would not lose their backs because of the difficulty of moving. At the same time, they also made room for a load of goods. It was definitely faster than it, but there were few people and small boats. There must be more people. So many people were tied together, and people often squeezed into a pile, and some people had to wait for the flash and delay time. It was difficult for laymen to compare. Boss Hu made a living here, and he was the first to make an estimate. The time it took to hang a cargo was only one and a half times the time it took for the porter to pick it back and forth. The efficiency was not only doubled, but also twice and triple!

Boss Hu was watching strangely, and scratched his head. The second round of goods came up again, and Boss Hu finally said: "It turns out that he is a scholar, and his knowledge is so effective."

The mighty man in the distance said, "Let's go back."

I knew it after seeing it, so there was no need to watch it anymore, but he smiled, which was magical, but the next thing was trouble. This magic was solved with strange tricks and tricks. The next trouble was human, and no coincidence was useful. See what this kid should do then!

There were people coming and going on Bian Dike, and no one would pay attention to these strangers.

Continue to pull.

Boss Hu felt itchy in his heart and said, "Xiaojiu, let me give it a try."

"OK."

He took the lead, and his brothers also drove He Erlang and the others aside and ran over to take over.

The ceramic ship was not big, and the cargo that originally required more than a dozen laborers to work hard for a long time was unloaded, but the cargo on the ship was unloaded empty.

All the coolies stared at each other.

Boss Hu put down the chain in his hand and said again: "It's time to be, it's still fast."

With the first ship as if it were, several ships were eager to try, looking for novelty! Without the need for brother-in-law to find him, he took the second ship of cargo.

Boss Hu pulled Song Jiu's arm on the shore. Song Jiu pretended not to know and continued to command.

Boss Hu pulled it up again and said loudly: "Xiao Jiu."

"Hu Xingtou, what's the point of doing?"

"A bet." Boss Hu said anxiously. It was not that he wanted to share the benefits, but that he immediately thought of the competitiveness of this matter. If a hundred such matters were erected on the river bank, he could easily defeat the Hebei porter.

"A bet?"

"Yes, let's talk about the bet." Mr. Hu shouted a little brother to take over his job and pulled Song Jiu aside and said.

"Okay, I'll just talk about my thoughts."

It is actually the shareholding system.

All the coolies in the river can invest, and the shares are distributed according to the head, and the capital is distributed according to the head. Another hundred elders will choose to manage accounts to prevent greed, assemble pulleys, patrol and guard, especially guarding Hebei coolies, and they cannot come and cause damage. In order to compensate these elders, each person owns two to ten shares, and only a few ten shares can be enjoyed by the ten shares, including Boss Hu. No one is allowed to disclose this technology.

As the initiator, Song Jiu is responsible for teaching technology and supervising the implementation, but must own one percent of the shares with his seventh brother-in-law.

"Xiaojiu, are you too many?" Boss Hu was not stupid and immediately reacted.

"Hu Xingtou, I'll do some calculations for you. Now this goods are controlled by the people on both sides of the river. The river accounts for a larger share, but the difference is not too big. With it, can we quickly grab the work in Hebei together? This is a double portion, at least half of the work can be grabbed. The unloading work is snatched and transported to various workshops. So has this work been snatched? Compared with these extra work, what is the share of these two small shares? Of course, you can't agree. I believe they are all neighbors, so you won't bring people to tear it down. With it, we can make more money. You can do whatever you want."

This is what Song Jiu has repeatedly thought about. One percent seems to be not much, but the Bian River canal transportation is busy. When it is free, there are usually hundreds of people working, and when it is busy, there will be thousands of people. In other words, he uses skills, which means that there are twenty or thirty people working for him every day.

This income is also quite large, and he can earn 60 or 70 yuan a month. At this time, the salary of officials and employees of the Song Dynasty was not very high, and he was far from the level of Bao Zheng's 30 million yuan a year. This income can be barely equivalent to the income of a prefect, which is similar to the income of a big sister's restaurant, and is even higher than that of the inn of the fifth sister. With it, Song Jiu directly entered a well-off level.

But it is not too high, so it won't make people jealous. In short, it is a very subtle number.

And it has a better future. Now there are four canals in the capital of the Song Dynasty, and the Bian River is not as prosperous as the Wuzhang River. However, with the stability of Huainan and the Southern Tang Dynasty, the total throughput of the other three canals is less than one-tenth of the Bian River.

"Xiaojiu, are you a leader or am I a leader?" Boss Hu changed his statement, meaning that I am the leader, but the division is far less than you, which is unfair.

"Hwa Xingtou, has such a thing happened since ancient times?"

Boss Hu thought for a while and said, "No."

"Ask a steward (the courtesan) to call the bureau, or go to a main store (the dozens of the most famous restaurants in the capital are called the main store) for a meal. The fewest ones are forty or fifty cents, and the most are for hundreds or even thousands of cents. And my creativity can be unique and unique, and it will be worth it?"

"This, this..."
