Chapter 1196: A Special Ship

When Zhao Yu left Beigang City and returned to the Seven Star Hanging Coffin, it was already past 3 o'clock in the afternoon.

Regarding the matter of apprehending the suspect Bai Lang, he had handed it over to Captain Fang Kaiyu; as for the matter of interrogating the staff of the funeral home and finding Bai Lang's accomplices, he entrusted Wu Xiumin to preside over it.

Therefore, it was still Xiong Wendong and other police officers who accompanied Zhao Yu back to the cliff of the Seven Star Coffin.

Through prior arrangements, when Zhao Yu and the others arrived, there were already several local boatmen who often ran boats, as well as engineers specializing in ships, waiting there.

Although the specific form is unclear, Zhao Yu is now more inclined to speculate that the criminals used boats to put the corpses into the hanging coffins.

He believes that criminals can refit an ordinary ship, and then install a set of elevators in the cabin, or simply drive the elevator to the ship, so that the purpose of lifting can be achieved!

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

The section of Baisha River below the hanging coffin of Seven Stars is more than 30 meters wide. Although there is sand on both sides of the river, the middle part is still somewhat deep.

Therefore, there are also many ships passing by Baisha Hanoi, but most of these are cargo ships transporting goods.

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

While observing the hanging coffin on the cliff wall, they discussed the method of transporting the corpse.

Looking up from below, you can see a cliff nearly 70 meters high, which is even more majestic.

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

"Officer..." At this time, a young engineer wearing glasses said, "I calculated according to your idea before, and I feel that there are still great difficulties in using the lifter!"

"Oh," Xiong Wendong hurriedly introduced to Zhao Yu when he saw this person talking, "This is Wang Rong, an engineer from our Songzhou Shipping Company!"

Zhao Yu nodded as a greeting.

"Police officer!" Engineer Wang pointed to the river under his feet, and began to explain his theory, "The main difficulty is the problem of weight.

"Look...the side of the river near the cliff is full of mud and sand. Boats in the river must stay away from it. If you get too close, you will run into danger of being stranded!

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

"Such a high height is absolutely impossible to achieve with modern lifting equipment, such as scissor lifts or lifting platforms used in repairing street lights.

"The only thing left is the hydraulic lift or the ladder fire truck of the fire brigade..."

oh……

Listening to Engineer Wang's explanation, Zhao Yu couldn't help admiring in his heart. He is worthy of being a well-educated engineer. His speech is logical and clear, and he can hear it very clearly.

"Let's talk about the hydraulic lift first, it relies on the hydraulic cantilever to achieve high-altitude operations!

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

"In this way, the ship does not have to worry about getting too close to the edge of the cliff and causing it to run aground.

"But..." He suddenly changed the subject and said, "Take this level of lift car as an example, it is not only bulky, but also has a dead weight of about 20 tons. Sailing is simply impossible!"

"That's right, the Baisha River is only as wide as it is..." Immediately, a boatman echoed, "The water in Kongjia Bay is extremely shallow, and a boat of this size can't get there at all!"

"Yes! The Baisha River is no better than those big rivers,

"Another boatman said, "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! That's the main point I want to say..." Engineer Wang said, "Aerial ladder fire trucks are used by fire brigades to save people. Because of the different purposes and functions, the fire ladder is more concise.

"As far as I know, the world's tallest ladder fire truck is produced in Finland and can rise up to 110 meters.

"Now the mainstream equipment of fire brigades in big cities can reach more than 50 meters!" Engineer Wang introduced, "Moreover, the ladder is erected, and it is also possible to reach the hanging coffin without getting close to the cliff!"

"Oh...if this is the case...doesn't it mean that the coffin can be closed?" Xiong Wendong spread his hands and said, "The criminal used the fire ladder to put the corpse into the hanging coffin?"

"But..." Engineer Wang frowned, and said in embarrassment, "There are two problems, but they still exist objectively!

"First, there is still the problem of weight! Although the weight of a ladder that can rise to about 50 meters is smaller than that of a hydraulic lift, it is not much smaller! At least about 15 tons.

"Such a weight can barely move during the time period when the water in the Baisha River is the most abundant..." He waved his hand, "The time when the water in the Baisha River is the most abundant is only in July and August every year, and the time is very short!"

"Hmm..." Zhao Yu nodded. "The hanging coffin case all happened after September last year. This inference is indeed untenable! Then... what about the second problem?"

"Second," replied Engineer Wang, "the aerial ladder fire trucks are all specially customized, and their prices are very expensive! Take the aerial ladder that can rise to 50 meters as I mentioned, for example. The cost of such an aerial ladder truck is about About 10 million RMB!

"Moreover, because of the single purpose, no other unit will spend money to buy it except for the fire brigade!"

"Then..." Xiong Wendong hurriedly said, "Could it be...they rented it from the fire brigade? I...I'll call and ask!"

With that said, Xiong Wendong hurried to the stern to make a phone call.

"I feel..." Engineer Wang said, "Whether it is Songzhou or Beigang, there should be no ladder fire trucks of this level! These two don't have skyscrapers at all!"

"And..." Zhao Yu shook his head and said, "The fire brigade may not rent out, and criminals don't dare to borrow?"

"The key is..." Wang Rong said again, "Even if we can get the ladder truck, the problem of the heavy weight of the hull still cannot 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 in the entire Fulai Province, I am afraid that only Xiakou City and the provincial capital Fulai City have it! Moreover, there are not many, and there is absolutely no way for the fire brigade to rent out!"

Wang Rong glanced at Zhao Yu and said, "How is it?" Is it the same as what I just said?

"However..." However, Zhao Yu didn't feel discouraged at all, and said, "It doesn't matter whether the hull is heavy or not, or what kind of equipment they use...

"But one thing is certain! If they really used boats to place corpses, then their boats must be huge and very different, right?"

"Oh...yes! You are so right!" Wang Rong instantly understood Zhao Yu's meaning, and hurriedly said, "Panjiawan Bridge and Songzhou Wharf have surveillance probes for Baisha River!"

"And we... already have the approximate time for them to place each corpse!" Zhao Yu nodded to Wang Rong and said, "Engineer Wang, this time, I have to ask you to do me a favor! Help us get that special ship— —Find it out!!"
