"Hehe, what about garlic, this should be good, if it's throwing bricks, will it fall and hit people?"

Niu Baobao is still very smart, this said to pretend to be garlic, Niu Baobao thought of throwing bricks, well, on the construction site over there, isn't there a brick thrower, what does it mean to throw bricks, that is, high-rise buildings, and not too high-rise, this brick, not transported up, but thrown up, and Yang Qiao here, naturally there is no need to throw bricks, there are construction cranes used.

Construction cranes?

Well, it is the kind of construction crane that was common on the construction site in Yang Qiao's previous life, this crane seems simple, well, it is really simple, it is just a crane assembled by some angle irons, but if you want to say that it is complicated, it is really complicated, there is a force problem here, that is, in Yang Qiao's previous life, I will often hear about where the crane fell down and how many people died.

At this time, the steel of the Tang Dynasty is not up to standard, naturally, the crane is more complicated, however, the complexity is not manufacturing, this manufacturing, as long as the drawings are produced, it is a small worker can be made, well, the craftsman at this time, is so good, that, is mainly the heart of learning, and the work of this small worker really does not need to be educated, and even, even some people who have reached the engineer level, not all work is solved with knowledge, but with experience.

Especially this crane, there really is no technology in it, as long as the material is up to standard, and the material is not up to standard, it is not something that these craftsmen can solve, they can only probe the quality level of this steel, well, it is the way to use sound to probe mentioned above, the craftsman, and later taught a few apprentices, although not so fine, but, some simple exploration, it is still possible.

Despite this, Yang Qiao still took out the design of this crane, and at that time, those craftsmen were as if they had seen something terrible, and they tried out this crane very sacredly.

Yes, it is a trial installation, not to create it, this has a drawing, not what the assembly is, but to set a part of the angle iron with the imperial iron factory, well, or the angle iron that provides the drawings themselves, and then, after the angle iron is processed, it is assembled to become, the so-called processing, naturally it is drilled, this shelf, not welded, or even partially welded, all the handover parts, are fixed with bolts, in this way, the craftsmen have one more task, that is, to check and fix, every day, or every few days, There will be a few people who climb on the shelves to check the fastening of the bolts, and check the strength of all the shelves next to each other to see if there are any cracks, and if there are cracks, they will be replaced faster.

Because of this, in the future, even if there is a more advanced assembly method, this inspection is still indispensable, and it has become a fixed procedure, so that the construction team of the Yang family, as long as it uses this crane, has not had any problems, that is, the carelessness in the hoisting has not appeared, and a group of very qualified inspection personnel have appeared.

This construction crane, in fact, is a matter of ideas, in Yang Qiao's previous life, he who had this idea made a fortune, well, I don't know who made it, and at this time, Yang Qiao used it first, so the invention of this crane became Huaxia, even if it was lost in the future, well, when I saw the archaeology of the Tang Dynasty, hey, this crane was actually available in the Tang Dynasty, and it was exactly the same, you copied us, take the patent, well, someone has the courage and ability.

Well, the crane is simple, but Yang Qiao's requirements are very strict, that is, this crane is assembled when it is assembled.

Oh, it's assembly, every time before starting construction, you have to assemble the crane, and when the construction is completed, it's disassembly and assembly, it's so complicated.

What is Yang Qiao's requirements, that is, safe and durable, that is to say, after being assembled, first of all, under the premise of complete safety, first mention several heavy objects that are more than twice the maximum lifting weight of this building for some tests, and then let the safety personnel climb up and down for several inspections, which can be considered successful.

This inspection is like this, the first person, first go up to inspect it, fill in the qualified form, and then, the second person follows the first person's road, inspect it again, fill in the inspection sheet again, and then, the third person, from top to bottom, and then inspect it, or fill in the inspection sheet, and finally, there is the fourth person's inspection, and the fifth person, these two people, it is counted as an inspection, one is from top to bottom, one is from bottom to top, until the middle meets, and then, or the inspection sheet, that is, this inspection, It takes five people, and then, within a fixed period of time, three levels of inspection, small inspection, medium inspection, comprehensive inspection, or general inspection, are carried out.

For this reason, whether the inspectors or the construction personnel, there is no one who is unwilling, that is, the construction personnel, would rather delay the work, make less money, and are willing to let people inspect, in the end, this is for their own safety, well, the main thing is that Yang Qiao advertises well, if something goes wrong, you see, so high places fall down, all fall into the flesh, naturally, this is a bit exaggerated, but, at this time, how can people have the opportunity to climb high, well, the tree is high, but, there are a few people who have nothing to climb the tree, so, said to fall into the flesh, I also believe it, although it really can't be made into a pulp, maybe, it can still survive, but this is crippled, it will be even worse, isn't it, although the Yang family's treatment is good, and they take good care of some people who are disabled in the line of duty, but who wants to be disabled.

Well, disability in the line of duty, there is no way to avoid it, even if you eat, you will choke to death, what can you say, you can only say that it is luck.

It's like playing a game, when playing a game, someone protects him very well, but when someone shoots him, he itches somewhere, when someone else's arrow comes out, he also lifts up his armor to tickle, well, no, it's a shot, as I said earlier, this arrow, although it is a safe arrow, but it will also hurt people, this is luck.

"Brother-in-law, what is this monster?"

Looking at the crane, the baby cow was very surprised, why didn't he find it when he came in front?

Well, at that time, it was not such a crane, but a simple three-brace crane, and a gourd, when the building was on the rise, it was similar to the appearance of the crane, but it was supported by the frame of the new building, and then, there will be a few large holes left on it, and then, after the construction was completed, the holes had to be filled, and now, this is gone, but the holes, there are still some, much smaller, this shelf, do you still need to use it.

"Baby cow, what about this, it's called a construction crane......

Balabala, Yang Qiao explained to Niu Baobao in detail.

"Brother-in-law, can you?"

Yes, this baby cow is filial piety, and when he heard good things, he actually thought of Li Er, no, he asked for it.

"This, you can have it, I drew this drawing, you can have someone give it to your father, but this gourd, the pulley needs to be purchased from the factory at home, and the angle iron, the imperial court iron factory can be made, originally, this angle iron is also bought from the imperial court iron factory, and the hoisting rope needs to be made by the father."

Hoisting, using a rope, is a rope, because after all, it is long, so, this chain, Yang Qiao feels that it is not suitable, in the end, he let people study a composite rope, that is, a kind of rope made of hemp, silk, and animal tendon mixture, after testing, even practical, are very good, is durable after all, after all, it is much safer than the wire rope developed at this time, well, wire rope, Yang Qiao has been developed, although there is, but, it is not up to standard, that is to say, Because the quality is not up to standard, it will be broken one by one, even if it is replaced in time, but I don't know when, there will be a collective tension, not a heavy burden, but the material is not up to standard.

The so-called substandard, that is, light, broken, heavy, but also broken, that, lifting building materials, who can guarantee that they are all the same weight of heavy objects, so, or do not use it, and at this time the place used, there is only one standard lifting place, and it is not easy to stand in the place below.

Well, it is said that people are not allowed to stand under the crane arm, but on what occasion, there can be a lack of people, so this warning can only be a warning, the station people, must also stand people, and only the implementation is stricter, when you can not stand people, try not to stand.
