"I'll just say, the chairman won't let us take such a big risk in vain." Li Yi said to Li Da beside him.

Li Da patted his chest, "I was scared to death, I thought I was really going to climb up alive." ”

Supreme Treasure patted Li Da on the shoulder, "You are quite self-aware, this climbing operation, you are the first to sign up." Come, I'll show you how to use these tools to climb this spiritual mountain. ”

Li Da's face turned slightly pale, but he still followed the Supreme Treasure to the front of these climbing tools and identified them.

"Do you know the name of the rope you tied just now?"

"Isn't it just ordinary hemp rope? Do they have any special name? ”

"That's right, this thing is called the main rope, which is the connecting line that runs through the climber, the protection point and the protector. The main rope is an indispensable lifeline in rock climbing protection. Don't underestimate this rope, the main rope is a multi-strand nylon rope wrapped together inside, and the rope skin is wrapped on the outside to fix and prevent wear. The main rope can be divided into power rope and static rope, which have different elasticity. A 100-meter power rope can be extended by six to eight meters when subjected to a force as heavy as yours, so that the climber will get a cushion when it falls off, reducing the momentum. The power rope is the main tool for all kinds of rock climbing activities. Static ropes are very malleable and are generally used for descent and caving. I won't go into too much detail here. ”

"Wow, is it really that strong?" Li Da picked up one of the main ropes and tried to grind it on the rock a few times.

"Don't mess around!" Supreme Treasure slapped Li Da's hand heavily, "When using the main rope, it is absolutely necessary to avoid cutting horizontally on sharp rock corners, and do not step on or drag on the ground to prevent cuttings and fine sand from entering the fibers and causing internal wear; Avoid contact with oils, alcohol, and flammables. Check before and after each use, eliminate regularly, and store in a cool, dry place when not in use. ”

"I see!" Li Da was embarrassed to withdraw his right hand, which was beaten red, and Li Yi and Lu Xiaoyu on the side couldn't help laughing wildly.

"What follows is the most important safety belt for your safety, which is worn on the climber and carries the weight and momentum generated by the climber's fall off or descent. The waist belt of the seat belt is the stressed part, and the rest of the leg belts are designed for comfort and convenience. When wearing a seat belt, be sure to wear the belt back from the belt buckle, otherwise there is a danger of pulling it apart when stressed; The head length after reverse wear must be more than 10 cm, and if it is shorter than 10 cm, it needs to be replaced with a larger model.

However, the ones I found to make this time were all made to a certain size, and only those who agreed with this standard could go up the mountain. A little bigger can't be smaller, and that's the standard for those who are the strongest to go up the mountain. Before climbing, the climber and the protector should check each other that the harness is worn correctly. ”

Everyone looked at the seat belt mentioned by the Supreme Treasure in two sections, the upper one was covered around the waist, and the lower one was very firmly covered by the two legs.

"This is because the belt and the protective ring are load-bearing, and the other parts cannot carry the weight of the human body; The load-bearing capacity of the equipment ring is less than ten catties. Seat belts with wide cotton pads on the waist belt and leg belt, comfortable but bulky, suitable for indoor climbing, line alignment; Originally, I was looking for a sponge pad, but we didn't have it here, so we had to use a cotton pad instead, but the effect was good. Like those who love to climb, they need lightweight harnesses when competing; When climbing traditional or apparatus, consider whether the number and placement of equipment loops is appropriate. Supreme Treasure saw that everyone was very emotional about the structure on the seat belt, so he explained.

"Huh? There are still people who love this climb? In the past, there were people in our village who climbed to the cliffs to get bird's nests and precious medicinal herbs, and if one was not careful, they would fall down. This activity is too dangerous, and there are still people who want to compete, which is really eating the heart of a bear and a leopard. Li Yi said in surprise.

"Big brother, you don't know, there are some young people who just like to play this kind of exciting thing, and we are all people with burdens on our bodies, and we have shackles in our hearts, so of course we don't want to climb. The so-called ignorant are fearless! Lu Xiaoyu said.

"Well, what the fourth brother said makes sense."

"Chairman, that's not good! They've found out where we're going! Xiao He hurriedly ran over and reported to the Supreme Treasure.

"What's the situation with Lao Xiao, how could we be discovered by them, aren't they still more than ten miles away?" Li Yi asked.

"Huh? Why is this iron rope here, I haven't found it for a long time, and I thought it was stolen by someone from another army who sneaked into our camp! That's fine, but, Chairman, what do you want these things for? Xiao He's eyes happened to sweep to the row of iron cables on the ground and asked.

"Old Xiao, what are you talking about? Why didn't I understand anything? ”

"Brother Li is like this, just now I went to count the number of people in the barracks for the last time, and found that all the locks in the barracks were gone, I was in a hurry, I thought it was discovered by Xiang Yu's people, so I came to inform the chairman. I didn't expect to see these locks here again. Xiao He pointed to the iron lock on the ground and said.

"Comrade Xiao, how did you hear that Xiang Yu sent Zhang Liang to come with 300,000 soldiers, you are a little calm, it's okay, relax, we can win. You just asked the soldiers, they watched me ask someone to take it, and you were a little too nervous. However, this can be said to be the iron lock of your gate, and it cannot be said that it is not the iron lock of the gate, you can take a closer look. Supreme Treasure patted Xiao He's shoulder and said with a smile.

"Huh? It does seem to be a little different, like it has been re-soldered. ”

"Is this also meant to be used for climbing?" Lu Xiaoyu asked.

"That's right, this is one of the tools for climbing. The metal ring with the iron lock can be opened and closed freely to connect all kinds of protective equipment and equipment together. The threaded iron lock can lock the iron lock door in a closed state when the screws are tightened, avoiding the danger of accidentally touching it; Ordinary iron lock without thread buckle device, light weight, easy to operate, can be used for temporary protection points, if the ordinary lock is used for fixed protection, must follow the principle of double iron lock and open door. The longitudinal tensile force of the iron lock is greater than the transverse tensile force; When the iron lock door is opened, the longitudinal tensile force decreases; The iron lock door is the weakest link and cannot be directly forced. The correct way to use it is to keep the iron lock door closed and longitudinally stressed. Avoid falling from high altitudes or hitting with hard objects; This will cause internal cracks and cause the lock to become invalid. ”

Finally, Supreme Treasure introduced to the protector, flat belt, quick hanging, rock plug, pitons, expansion nails, hanging pieces, impact drills, bouldering pads, helmets and other climbing tools, everyone heard a little understanding. But it doesn't matter, the main event is still to come!
