"T-type rescue is a thod to save those trapped on sand dunes or isolated islands in the middle of canyons or rivers. It’s mainly applicable in situations where both banks are of similar height and the rescue depth isn’t too significant!"
If it’s a mountain stream, we usually use trees as support points at both ends, while in cities we use beams and columns.
Second, there is the displacent system, which includes lateral and longitudinal displacent..."
The explanation process was exceedingly dry.
But for every firefighter, it was sothing new, sothing life-saving.
To be precise, it was sothing to save others’ lives.
A new technique could possibly allow them to enter spaces they previously couldn’t.
But in the eyes of Fang Huai, who was digesting the knowledge, this traditional T-type rescue still had many flaws. Although it saved on equipnt and manpower, its efficiency was sowhat lower.
Moreover, the lack of safety equipnt was infuriating. There ought to be one rope responsible for lateral movent and another for longitudinal movent, yet there was no professional load-distributing tal plate. The ropes for lateral movent and descent were actually managed by a single rope tied into four butterfly knots to serve the load-distributing function.
Fang Huai felt powerless to criticize.
They wanted to implent advanced T-type rescue, and yet they relied on these primitive thods.
To go without dual-rope protection was one thing, but then to worry about the rope sling being pulled down into a knot, and then having to use a stretcher to haul soone up from below, was it all so kind of Little Flying Knight scenario?
A sensible rescue system should replace manual work with equipnt wherever possible!
However, Fang Huai was aware that it would probably take many years to perfect these equipnts. For now, the issue was not just about safety, but about having the equipnt at all.
In an actual ergency, just like in the past when they could only rely on a three-loop waist knot for protection, when it was ti to go, they had to go.
It’s tough being a firefighter these days.
Our country’s firefighting rescue teams started late in rope technology, introducing Japan’s spiral rope technique around the year 2000 to begin filling the gap in dostic firefighting rope technology.
They also began to study so of the maneuvers.
But that thing really depends on skill. It emphasizes simplicity, minimal equipnt, less protection, relying on ropes for everything, requiring high proficiency. Even the newer protection thods adopted SRT (single, single-rope protection) as the main approach.
There was no collaborative protection. A mistake could not be made, or it would co down to how tough the figure-eight knot was.
This thod was in use until the past two years when Hong Kong took the lead in starting to engage with Western rope technology. But even the DRT (double, dual-rope protection), involving multi-person collaboration, still lacked experience.
The rope technology philosophies of Japan and the West were like comparing Japanese cars to Arican or German cars. One is lightweight and fuel-efficient, the other is safe and durable. You can’t say lightweight is bad, but if you really get into a crash, you’ll regret not having invested in more insurance.
The main issue is still the lack of equipnt.
DRT protection requires a lot of equipnt, expensive, needing more personnel, but it’s safer with high fault tolerance.
Don’t underestimate those rope equipnts. They are very precise, and the good ones are very expensive. In an actual rescue, if one carabiner fails, serious problems can arise imdiately. The equipnt wears out quickly and requires a large stock.
Furthermore, our country’s training institutions for rescue rope technology are chaotic and diverse, with different technical categories, lacking strict regulation of the qualifications of the instructors.
Starting late, we mostly use others’ inventions. Not only are we unable to use them properly, but we also have to pay for training. The design logic belongs to others, and they hold patents for many of the components, making so training fees unavoidable.
Nevertheless, today wasn’t all bad; I did bring the rescue harness with .
Honestly, considering ropes, an ordinary person would have trouble just tying shoelaces neatly, let alone dealing with such a complex rope system. Most people wouldn’t even understand it, let alone manage it.
But fortunately, after so many years, since it’s an important lifesaving equipnt and an assessnt item, everyone has had a lot of practice with ropes, so their understanding of rope systems isn’t bad. Quickly, they took apart the entire system into components of protection, traction, braking, and focused on researching the prepared T-type system.
Then, holding ropes and various carabiners, pulleys, they started tying them one by one.
During the lecture, the pot was full of mouse droppings, but when it ca to practice, everyone turned into good students.
Fang Huai was different, though. He was the type who aid for Tsinghua University, the kind who liked to take a few carefully selected difficult questions to trouble the teacher after class.
"Wuya, for one end of the transport rope, you make a double figure-eight knot, hang it with a safety hook, and connect it to the hole on the lower side close to the opposite bank of the load-bearing rope, right? And inside the corresponding hole on the load-bearing rope, connect a single pulley with a safety carabiner?"
Wouldn’t it be better to use a self-locking carabiner for this top one?
Wuya: "Hmm, yes, you can do that. There are self-locking ones. Go get them from the truck."
Since it’s single-rope protection, the load-distributing board... the load-distributing rope, on top, can another main lock be added?
Wuya: ...
Seems like you’re nitpicking.
"The main thing is to understand the principles."
Fang Huai: emm...
"As for principles, you also omitted so safety details. One is that an ID has to add a friction lip when feeding the rope, and another is that when installing life lines, each rope should be left with excess to facilitate movent. This maneuver is too complex, and there may be more to it. I’m not very clear on the rest. The safety precautions are too nurous. I suggest putting together a booklet of construction precautions."
Wuya: "...Yes, that’s possible. I can make a booklet for you guys."
"Hmm, after you make it, I’ll help you review it and add so stuff."
Wuya: ???
I thought you said you weren’t very clear?
"Why don’t you demonstrate it once?"
Hu Peizhou finally spoke up from the side: "Number 1 will demonstrate first, I’ve already decided."
