本帖最后由 dol528phin 于 2015-3-26 12:54 编辑 网上搜罗,教授攀岩技巧的文章不占少数,却很少有文章谈谈如何才能成为一名合格的保护员。而攀岩者的安全恰恰就是掌握在保护员的手中(solo 攀岩的除外)。这样弃本逐末的教学未免让人觉得过于大意了。从我个人的经验看来,保护绝不单单是“绝不放开制动手”那么简单,尤其是进行先锋保护时,绳子在一收一紧间,步子在一进一退间都充满了玄机。只有攀岩者与保护员的完美配合,才能成就一次次的红点。每个攀岩者的另一个身份都是一名保护员,那我们就应该在提高攀岩技巧的同时,也提高保护技巧,这样才能和小伙伴们玩耍得更嗨皮更安全。 ~~~敬请阅读~~~ 25+ Ways To Be A Better Belayer Give a safer and softer CATch with these techniques By Julie Ellison 25条让你成为金牌保护员 有了这些技巧,为你所保护的人提供更安全,更舒适的保护 翻译 芽子 Climbers are constantly trying to increase their strength and improve climbing technique, while belaying the leader is often viewed as a stagnant skill: Once you know how to feed out rope, take in slack, and catch a fall, you’re done. False. All climbers should strive to refine their belaying practices throughout their climbing career, which means learning and practicing the subtleties that make a truly great belayer. We’ve talked to guides, longtime climbers, and even a physicist about how to give the best catch possible in a variety of situations, and we’ve compiled all that information here. Dial in these methods every time you go to the gym or the crag, and your top-notch belay services will mean you’ll never have trouble finding a partner again. 攀岩者们都永不停滞地试着增加力量、提高攀岩技巧,而保护攀岩者却不被重视:一旦你知道如何给绳,如何收绳,如何制动,就大功告成了。错。所有的攀岩者都应该在整个攀岩生涯中努力改善自己的保护技巧,这就意味着攀岩者要学习和练习其中的微妙之处,那样才能成为一个真正的保护者。我们和攀岩向导谈过,和老岩棍谈过,甚至和物理学家谈过,讨论在不同情况下如何才能做到最好的保护,我们在这里将所有这些都编辑在了一起。在每次你去岩馆或去野攀的时候都把这些要点过一遍,那么你的顶级保护技术将意味着你永远都不愁找不到搭档。
Before the climb >>Wear closed-toe shoes to protect your feet if you’re being pulled up through obstacles, jumping into the air, and deflecting off the wall. >>Belay gloves will give you increased control of the rope (including better grip on skinny cords), as well as protect your hands from rope burns and anything that might get stuck in the rope as it drags across the ground toward your brake hand. (Think: A cactus needle stabbed one belayer in the hand and resulted in him dropping the rope completely.) >>Check your belay stance by making sure you have a clear path between you and the cliff (in case you get pulled into it), and be aware of loose rocks as you shift your position by stepping forward or backward. >>This is more of a belaying bASIc, but it can’t be stated enough: Always double-check your belay setup and the climber’s tie-in knot before he leaves the ground. >>Communication between climber and belayer is key. For more info on this, check out Know The Ropes. >>If you are a lighter belayer, don’t anchor yourself to anything on the ground. That would result in a hard catch on the climber and a violent jerk for you. If the climber is significantly heavier than you and long falls are possible, consider finding another belayer. >>Golden rule of belaying: Belay others as you’d like to be belayed. Focus on your leader, don’t get distracted, and pay attention. >>Talk through how to belay a route beforehand. Maybe there are slab sections, roofs, near-groundfall clips, etc.; it helps to agree on how each section should be belayed so both partners are on the same page. >>If you’re heavier than your climber, know how to give a dynamic belay (see below). 攀爬开始前
During the climb >>Smaller belayers should consider using an assisted-braking device and standing really close to the base of the wall, near the first clip. This will help catch a fall and minimize the distance the heavier climber falls, which also minimizes the distance the climber has to yard up to get back on the route. Since lighter belayers will get pulled into the wall naturally, be aware of the lowest pieces of protection. We’ve heard horror stories of broken fingers as a result of being catapulted into the first draw. >>Whenever you’re not feeding slack, be prepared with your brake hand in a locked position. The climber might be tired, off-route, out of sequence, scared, or even just evaluating a loose hold. If the climber isn’t climbing, he might be falling, and even when he is climbing, he might be about to fall! >>Exercise situational awareness; know where your climber is and what he might hit if he takes a fall. He might need a bit more slack to clear a roof and fall into space, or he might need less to avoid hitting a ledge. >>Keep tabs on the rope: the location of the midpoint (will you still be able to lower the climber?), where the end is, the amount of stretch you expect, that the coil is feeding smoothly to you, there are no knots in the rope, etc. >>It’s your job to alert the climber if his leg gets between the rock and the rope (this can cause him to get flipped upside down in a fall and hit his head). If you see this happen, alert the climber by yelling up to him: “Joe, watch your leg!” or “Joe, watch the rope!” >>It’s also your job to alert the climber if he has Z-clipped (clipped the rope from below a lower piece into a higher piece) or back-clipped (instead of the leader’s rope running up through the draw and away from the wall, the rope runs up through the draw and out between the biner and the wall. If you didn’t already know what these things are, consider taking a basic lead-belay course.) Yell up to him to correct his mistake. >>When the climber is low to the ground, you’ll want less rope out to keep him from hitting the deck. As he moves up, you can keep a bit more slack in the system so he has ample rope to pull up and clip. >>Anticipate clips and be super-active with the rope, whether he’s clipping below his waist or way above his head. You’ll need to quickly feed out slack to avoid short-roping him (meaning you stop the rope from feeding through, which is not only annoying for the climber, but could cause him to fall at an inopportune time), but if he can’t make the clip or drops the rope suddenly, you’ll want to quickly reel in slack to avoid a huge fall. >>On the very start of a climb, the belayer might need to stand off to the side of the climber so he doesn’t land on your head if he falls. The belayer also might need to help the climber step over the rope by moving in closer to the wall or repositioning the rope. >>Encourage and reassure your climber as much as you can. He might need that extra push to get through a hard or scary move. Simple words like, “You got it!” or “Keep fighting, Joe!” might go further than you think. >>An assisted-braking device might not lock up completely if your climber is very light, if the climber sits back on the rope (instead of falling), or if there’s a lot of rope drag—more reasons to always have a hand on the brake side. >>Before the climber makes the first clip or places his first piece, spot him by standing slightly behind and having your hands up, ready to guide his fall safely to the ground. >>If the climber takes a fall higher on the route, you can assist him in getting back up by sitting back and putting all your weight on the rope while he pulls the rope down toward you. Time it right so you’re weighting the rope while he’s pulling himself up, and then quickly pull slack through your device. Repeat this process until he’s back to where he wants to be. Same goes for boinking: Make sure the rope is fully weighted when he’s pulling up. >>To avoid aches and pains while belaying, shift your weight between feet, take a step to the side to slightly change your stance, move your neck and eyes as much as possible, and stay loose. To prEVENT and treat the dreaded belayer’s neck, check out this handy guide. >>When lowering on a sport climb, step forward so you’re practically leaning against the rock directly under the First Bolt. Lowering the climber while standing away from the first bolt puts a tremendous amount of outward force on a bolt that is primarily designed for a downward force. Plus, this bolt sees more traffic and impact than almost any other bolt on the climb.
Dynamic Belaying When the leader starts to fall, our first instinct is to lock down the rope quick and hard, minimizing the overall distance the climber will fall. This can cause a leader to slam hard into the wall, resulting in snapped ankles, jarred spines, and serious head injury if the climber falls upside down. A way to mitigate this is to aim for giving a “soft catch” by dynamic belaying, which eases the climber into the wall and greatly reduces the chance of injury. Keep in mind that a dynamic belay isn’t always appropriate and it’s an expert technique, so make sure the answers to the following questions are yes before you employ this method.
The Process We talked to physicist and climber Adam Scheer to see how a dynamic belay works. The belayer jumps as the climber begins to weight the rope. Because the belayer introduces upward momentum from the jump, it momentarily takes less work to continue pulling him upward, in essence reducing his weight from the standpoint of the climber. This lengthens the time over which the catch takes place, thus softening the catch. The belayer needs to stay light on his feet and be prepared to get pulled into the wall quickly. Keep knees and feet soft for low impact. Timing the jump is a mix between art, science, and practice, but you want to be moving upward just as the climber starts to put downward force on the rope. Falls happen quickly, so if the climber isn’t very high above his last piece, the belayer can usually plan to jump as soon as the climber comes off. If the climber is 10 feet or more (spicy!) above his last piece, the belayer can wait a split second before jumping. >>Don’t feed out extra slack. This results in a harder catch because it increases the fall factor. If a climber takes a 10-foot fall with 20 feet of rope in the system, the fall factor is 0.5. If the belayer includes an extra five feet of slack (15-foot fall, 25 feet of rope in the system), the fall factor increases to 0.6, resulting in a harder catch (increased maximum force). Only give extra slack to make sure the climber clears an obstacle. >>Don’t mistime your jump. If the belayer jumps too early, his center of gravity will actually be on the way down when the climber is reaching the point of maximum force. The belayer acts as a counterweight, and if he is traveling downward, his momentum will be counteracted by the falling climber, causing a harder catch. >>Don’t run toward the wall, which will not soften a catch when the first piece is high (20 feet or more). This is dictated by trigonometry. (Scheer says, “Trust me, I’ve done the math.” For more info on this, visit climbinghouse.com.) 动态保护 当先锋者发生冲坠时,我们的第一个本能反应就是快速猛力地制动住绳子,借此最小化攀岩者的坠落距离。但这样会使攀岩者猛力地撞向岩壁,导致脚踝受伤,脊柱震荡,如果攀岩者是大头朝下发生坠落的话还可能发生脑损伤。避免这种事情发生的一个方法就是运用动态保护,给攀岩者一个“舒适的制动”,这样可以降低攀岩者撞向岩壁的概率,避免受伤。切记,动态保护也并不总合适的,这是一门专业技术,因此,在你应用动态保护之前,要先确定你对以下三个的问题给出了肯定答案。
保护过程 我们与物理学家,也同是攀岩者的Adam Sheer讨论了动态保护是如何实现的。当攀岩者的重力开始作用于绳子,保护者就起跳。保护者在这个时候就引入了一个向上的力,而此时,攀岩者向上拉保护员所费的力就变少了,这就相当于攀岩者来说,就等同于降低了保护员的重量。这样也延长了制动发生的时间,进而使得制动变得很舒服。攀岩者应该放松站立,做好被迅速拉起撞向岩壁的准备。通过放松双脚和双膝来降低冲击力。调整动态保护的跳跃是一项集艺术、科学和实践于一体的事儿,但有一点是可以肯定的,那就是在攀岩者开始向下施力的时候,你才向上跳。冲坠经常以迅雷不及掩耳的速度发生,所以当攀岩者离他最后一个保护点不是很高的时候,保护者的起跳时间基本可以与攀岩者的冲坠保持同步。而如果攀岩者发生冲坠的时所在高度高出最后一个保护点3米或更高,保护者就可以在起跳前登上一秒。
