Chapter 1198

When Zhao Yu left Beigang city and returned to the Seven Star hanging coffin, it was more than 3 p.m.

About the arrest of the suspect Bai Lang, he has handed it over to the captain Fang Kaiyu; As for the interrogation of the staff of the funeral home and the search for Bai Lang's accomplices, Wu Xiumin was fully entrusted to preside over it.

Therefore, at the moment, it is still Xiong Wendong and a line of police officers who accompany Zhao Yu back to the bottom of the Seven Star hanging coffin cliff.

Through prior arrangement, when Zhao Yu and others arrived, several local boatmans who often run boats and professional engineers of ships were waiting there.

Although the specific form is not clear, Zhao Yu is now more inclined to the speculation that criminals use ships to put the bodies in hanging coffins.

He believes that criminals can completely refit an ordinary ship, and then install a group of lifting machines in the cabin, or simply drive the lifting car to the ship, so as to achieve the purpose of taking off!

However, in order to verify this possibility, he still found local boatman and professional ship engineers to discuss with them.

The Baisha River under the Seven Star hanging coffin is more than 30 meters wide. Although there is sediment on both sides of the river, there is still some depth in the middle.

Therefore, there are many ships passing through Baisha Hanoi, but most of them are cargo ships transporting goods.

At the moment, in order to see more clearly, the local police arranged several simple wooden boats. Zhao Yu and others came to the bottom of the cliff in this wooden boat.

While observing the cliff coffin, he discussed the method of transporting the body.

Looking up from below, you can see the cliffs nearly 70 meters high, which is even more magnificent.

As the cliff slopes inward from top to bottom, it seems that there is a sense of oppression that the building is about to collapse, which makes people feel dizzy.

"Officer..." at this time, a young engineer wearing glasses said, "I calculated according to your idea before. I feel that it is still very difficult to use the elevator!"

"Oh," Xiong Wendong hurriedly introduced to Zhao Yu when he saw this man talking, "this is Wang Rong, an engineer of our Songzhou shipping company!"

Zhao Yu nodded and said hello.

"Officer!" Engineer Wang pointed to the river at his feet and began to elaborate his theory, "the main difficulty is the problem of heavy load.

"Look... There are sand shoals on the side of the river near the cliff. You must stay away from ships in the river. If you get too close, you will run aground!

"Look again..." he raised his head and pointed to the hanging coffin above. "The hanging coffins are all 20-40 meters high. If we make scientific assumptions, we must take the highest 40 meters as an example.

"Such a high height, if modern lifting equipment is adopted, it is absolutely impossible to reach such a high height as the scissor lift or lifting platform used in the repair of road lamps.

"What's left is only the hydraulic elevator or the ladder fire engine of the fire brigade..."

Oh

Listening to the explanation of engineer Wang, Zhao Yu couldn't help but praise him. He was worthy of being a educated engineer. He spoke logically and hierarchically, and listened very clearly.

"Let's first talk about the hydraulic elevator, which relies on the hydraulic cantilever to realize high-altitude operation!

"As far as I know, the most advanced elevator can reach about 30 meters," engineer Wang continued. "Moreover, the cantilever has strong extensibility. Even if the ship stops in the middle of the river, the cantilever can still extend to the cliff.

"In this way, the ship doesn't have to worry about being too close to the edge of the cliff and grounding.

"But..." he suddenly turned and said, "for such a level of elevator, it is not only huge, but also has a self weight of about 20 tons. Coupled with the quality of the hull itself, it is impossible to sail in the Baisha River!"

"Yes, how wide is the Baisha River..." immediately a boatman agreed. "The water in kongjiawan is very shallow. Such a big ship can't drive at all!"

"Yes! The Baisha River is no bigger than those big rivers, "said another boatman." our company basically controls the loading of sand and soil materials at about 10 tons! "

"So... What about the fire ladder?" Zhao Yu asked.

"Yes! This is what I want to say... "Engineer Wang said," the ladder fire truck is used by the fire brigade to save people. Because of different purposes and functions, the fire ladder is more concise.

"As far as I know, the highest ladder fire engine in the world is produced in Finland and can rise to 110 meters.

"Now the mainstream equipment of fire brigade in big cities can also reach more than 50 meters!" Engineer Wang said, "moreover, the ladder is erected, which can also reach the coffin without being close to the cliff!"

"Oh... In that case... Isn't it equal to a conclusion?" Xiong Wendong stood up and said, "the criminal put the body in the hanging coffin by using the fire ladder?"

"But..." engineer Wang frowned and said in embarrassment, "there are two problems, which still exist objectively!

"First, it's still a heavy problem! Although the weight of the ladder that can rise to about 50 meters is smaller than that of the hydraulic elevator, it is not much smaller! At least about 15 tons“ Such a weight can only barely move in the most abundant period of Baisha River... "He waved," when Baisha River is most abundant, it is only in July and August every year, and the time is very short! "“ Well... "Zhao Yu nodded," the hanging coffin cases all happened after last September. This inference really can't be established! So... What about the second problem? "“ Second, "engineer Wang replied," ladder fire engines are specially customized, and their prices are very expensive! Take the ladder that can rise to 50 meters as an example. The cost of such a ladder car is about 10 million yuan“ Moreover, because of the single use, no other unit will spend money to buy it except the fire brigade! "“ Well... "Xiong Wendong said hurriedly," will they... Rent it from the fire brigade? I... I'll call and ask! " With that, Xiong Wendong hurried to the stern and called“ I feel... "Engineer Wang said," no matter in Songzhou or Beigang, there should be no ladder fire engine of this level! These two have no skyscrapers at all! "“ And... "Zhao Yu shook her head and said," the fire brigade doesn't necessarily rent out, and criminals don't dare to borrow it? "“ The key is... "Wang Rong said," even if we can get the ladder truck, the problem of heavy hull can't be solved! "“ Officer Zhao! " At this time, Xiong Wendong shouted from the stern, "I asked, our fire brigade doesn't have such awesome equipment at all“ They told me that only Xiakou city and Fulai City, the provincial capital, have the whole Fulai province! Moreover, there are not many. It is absolutely impossible for the fire brigade to rent out! " Wang Rong glanced at Zhao Yu and said: how about it? Is that what I just said“ But... "However, Zhao Yu didn't mean to lose heart." no matter whether the hull was heavy or not, or what kind of equipment they used... "But one thing is certain! If they really use ships to place corpses, their ships must be very big and different? "“ Oh... Yes! You are absolutely right! " Wang Rong instantly understood Zhao Yu's meaning and hurriedly said, "there are Baisha River monitoring probes on Panjiawan bridge and Songzhou wharf!"“ And we... Already have the approximate time for them to place every corpse! " Zhao Yu nodded to Wang Rong and said, "engineer Wang, this time, please do me a favor! Help us find that special ship!
