Let me talk about clothing first. I didn't use jumpsuits at first, instead of camouflage, but the shortcomings were very obvious - I was naked! ! Caves involve a lot of ascents, descents, and crawls. It's inevitable that between the “hands and feet†will cause the clothes to break up and down. This will make it easy for the sand to enter through the waist, resulting in the avoidable embarrassment.
The use of “waterproof and breathable assault trousers†is more undesirable. Some caves have very high humidity, ventilation is a decoration, and the inevitable strong scraping is very damaging to this type of “expensive†clothing.
Therefore, bodysuits become necessary, PETZL product line has such, but the price is very expensive, contrast performance, some domestic labor protection coveralls become the first choice. For the convenience of observation in the cave, it is also worth recommending that you sewn the reflective strips in suitable locations.
Then come the technical equipment
From top to bottom:
1 helmet + lighting system
Ordinary rock climbing helmets + led/halogen lamps can basically meet the requirements of use, but the disadvantages are also obvious, especially the headlights.
LED lights - too low illumination is the biggest problem. (1) White light irradiation has a very large adverse effect on the judgment of the distance; (2) The irradiation distance is too close and the range is too small, resulting in that some tunnels cannot be effectively found, and caverns differ from mountaineering in that there are no clear goals. Most of the Under the circumstances, we have to rely on "the mountains and the rivers have no way to make a mistake, and we have to spend a long time on the villages," so the glare has a great influence on the discovery of the tunnel - the result of the activity. Its only advantage is that it has long battery life and can be carried as a backup light source.
Halogen lamp - the irradiation distance can indeed, but the irradiation range is not wide enough, there is still a similar problem with the led lamp, and it is too power-consuming, the main light source for caving will inevitably cause the need to carry large capacity power supply.
Solution: The halogen lamp and the LED are applied together, and the halogen lamp is turned on for a short time
Acetylene lamp + halogen lamp + led (backup) - The above problem has been completely resolved, and cavern preferred.
2, seat belts
Mountaineering/climbing belts are perfectly suitable for cave environments, although textbooks are not recommended
The advantage is comfort, the disadvantage is that the structure is more complex, it is easy to be hooked when detecting a narrow hole, and because it is thicker, cleaning at the end of each event becomes a nightmare.
The advantage of cavernous seat belts is that they overcome the disadvantages of climbing/climbing belts, but they are less comfortable. Its special structure cooperates with "Mei Lun" to reduce the risk that the lock door will open when the equipment is wound up and down and the equipment is intermingled and collided with each other.
3, rising, falling system
Down: 8 characters, ATCXP, STOP, ROCK
8 words, not used in the hole, it's hard to say;
ATCXP, at that time, because STOP hadn't arrived yet, ATCXP was used to replace the STOP function with the grabbing part attached to the leg ring of the seatbelt. However, it was found that the operation of the ATCXP was too cumbersome when passing through the node. Only carried as a backup device.
STOP, this is a good thing, and due to its structure, there is no need to worry about falling out of the way when it is going up and down, but after the rope is loose, there will still be a slight drop (difference in the degree of fall due to the thickness of the rope). Therefore, if you want to stop doing other operations midway, you must hit a "hard lock" to ensure safety. As for foreigners' use of a metal lock to fully release their brakes, Xiao Kee has no such confidence and courage.
Note: The rope entry operation before descent must be correct. Once it is in the wrong direction, it will cause its function to fail! !
ROCK, also a good thing, is just not ready for use because it has just arrived.
Ascending system: right hand rise, chest rise, chest strap, foot strap, foot lift
Not to mention, the most basic configuration is the right-hand rise, chest rise, chest strap, and pedal strap. It has been tried to replace it with the ice crack self-rescue system, but the experience of being trapped in the next half hour of a house's bumps on a rising road made me completely reverse This wrong understanding. It is worth mentioning that most people use the right-handed assault + single-loop pedal belt. In order to save effort, I have used a double-ringed pedal belt (frog-type climbing rope). The chest strap should be tightened as much as possible so that the chest rise is as close to the body as possible during the ascent, avoiding the body to throw back and reducing physical exertion.
Feet have risen, are rarely used, have not encountered a very large shaft, so the things that increase the cumbersomeness of the operation have only been used in training, but they are used together with the above systems, which can reduce physical exertion and at the same time can speed up the rise. Rhythm.
It is necessary to mention the oxtail rope. When it comes to initial descent/decrease, and when the instrument is replaced, the oxtail must be used to make sure that the oxtail is responsible for the relevant operations. It is absolutely necessary to avoid unprotected operation.
4, package
It's better to use a caving package, wear-resistant, easy to stuff a small hole, easy to wash (can be homemade, you can also buy ready-made products, I know that petzl, singingrock, Ketuo have a caving package for sale, last week has Seeing Ketu's cave bag at the local equipment store - using the same material as its 60 liters/110 litre bag), the foreign stuff is very expensive and Keito is very cheap. I didn't wait until Kevin took out this bag, friend. I used rubber boat rubber materials to imitate petzl Portage DIY. I was sprayed with petzl's LOGO by my very clumsy and shameless. The material was stronger than Ketu's. A caving hole that carries a regular backpack can make one regret it when cleaning it.
Other equipment:
1, shoes, ordinary walking shoes, thick-soled rain boots
Ordinary hiking shoes - more comfortable, the premise is dry, once run into the hole had to wading, it is more rampant, and the performance of the index, the first anti-skid, and because of the use of the environment is too bad, a pair of cheap Just fine.
Thick-bottomed rain boots - thick-bottomed products on the market are really hard to find, but there is a guy who uses the "work of the job" and engages in double-entry fire boots. Everything is better than being bulky and the protection of toes is stronger than bargains. A lot.
2, shooting equipment
It is better to be light and waterproof and vibration-proof, and try not to carry a large-sized camera bag. It is annoying to wear too many strings and climb in the hole. Some local people (including me) use the Binder WP/WPI/W10 series.
3, protective gear
It is best to prepare, ordinary soft knee pads elbow available, hard line, WARGAME used for the "Black Hawk" protective gear preferred, cheap, strong, as a consumable equipment is very good.
4, toxic gas protection device
After a few bad guys got out of the hole in the middle of the night, they actually ran out of waste gas from nearby factories, causing them to poison most of them. So they smelled bad news and engaged in a simple mask.
