關於如何檢查攀岩的主繩,一時之間找不到相關的資料可以提供,不過網路上有些文章寫得相當仔細,足以提供攀岩者檢查主繩的依據(請參考:://www.justropes.com/shop/custom.asp?recid=8#IO)節錄如下:
Inspect Your Climbing Rope Often:
You rope is an amazingly strong and durable piece of equipment, but it is not fail-proof. It is your responsibility to regularly inspect the thin line that will be keeping you off the deck. Don't get lazy or apathetic about frequently looking over your rope to be sure it is free of serious damage and is still safe for use! The best habit is to closely inspect your rope each time you take it out of its bag for the first climb of the day. It doesn't take much time, and can be done while the leader gears up. A minimal habit is to inspect your rope every couple of times out, and always after any incident (such as rockfall, or a fall or pendulum over a sharp edge) that you think may have hurt the rope. Take the rope in you hands, and inspect it visually foot-by-foot, while at the same time inspecting it by touch with your hands. Look for obvious cuts, areas of extensive sheath abrasion or "fuzzy" spots, places where you can see the core of the rope (white), or obvious distortions in the rope shape that do not seem normal. Feel for '"soft spots" that can indicate internal damage to the core of the rope, and if you detect anything suspicious, take a closer look visually, bending the rope into a loop and twisting the rope at the soft spot to see if the ropes distorts or does not bend in a normal manner. When in doubt, suspect the worst. Ask a more experienced climber to take a look. Err on the safe side. If the suspicious spot or damage is near the end of the rope, cut it out. The remainder of the rope can still have some useful life. If the damage or suspect spot is in the middle of the rope, retire it. It's worth the peace of mind, as well as many more years of future, safe, enjoyable climbing, to just buy a new one!
紅色的那一段話與我先前看到的資料有點雷同,正常的繩子應該要有相當好的柔軟度,彎折之後不可以有任何不平整的地方(也就是不能有任何凸起、或凹陷的狀況)。
最新一期的Rock & Ice雜誌(2006年10月號)有個主繩斷裂的意外報告,那一條Black Diamond的繩子雖然用的比較久(約6年),但外觀看起來完全正常。有位攀岩者在某岩場進行先鋒墜落測試時(Fall Factor僅約0.3),主繩應聲而斷,所幸摔到岩場的軟墊上,並無大礙。BD的實驗室部門在經過檢查後,同樣沒有發現繩索上有任何可疑的磨損,該人工岩場岩壁上也沒有任何可能切割到主繩的物品。
斷裂的主繩被送至歐洲一間專門生產攀登繩繩蕊材料的公司作檢驗後,發現在斷裂處有不正常的硫化物反應。生活中最容易產生硫化物的東西是:電池。該主繩的擁有者說明這條繩子從來沒有跟電池擺放在一起過,也沒有借過別人使用,唯一有可能接觸到硫化物的機會,可能是在攀岩的停車場整理裝備時,會將繩袋放在地上,有可有些車子的電池有些微滲漏,使硫化物侵蝕主繩結構。
除了車用電池之外,充電電鑽的電池也是攀岩者必須要注意防範的地方。
以上資訊,僅供參考。主繩還是有可能會斷的。

Dear All,
同樣在www.justropes.com/shop/custom.asp?recid=8#IO的文章中,可以看到清洗主繩的建議。大部分廠牌的主繩說明中,都建議必須定期清洗主繩,以延長主繩使用壽命(原因已經有討論過)。我想有些人會建議不要洗主繩,可能是因為不希望主繩的防水性在清洗過後變差,所以才有這樣的建議。
我個人是建議以大約三個月至半年的頻率來清洗,不過如果有碰到海水的話,建議要直接清洗。

Petzl的網站有一些影片,也許有人已經看過了,
其提供繩子的檢查方式,還有其他裝備的檢查,
大家可以參考一下.

但是主繩以外的裝備使用年限如何得知?
編織繩類因為會有纖維老化的問題,主繩一般建議不要使用超過六年(每個廠牌、每個地方地建議都不太相同),同理可以推想至吊帶以及傘帶的壽命應該也是類似的。比較好記憶的方法就是,主繩該換的時間,吊帶也可以準備一併更換。
至於金屬器材方面,只要保養得當,金屬器材用個10年、15年都不成問題,主要要看每個個別鉤環的磨損程度,只要沒有什麼磨損,都可以一直用下去。
以上是個人的淺見,不知道其他人的看法如何?
