这里(英文的)有一篇如何延长机械塞扁带的网站,对我很有启发。人家是仔细做过实验的,有说服力。
基本的意思是,最好用小锁。
如果实在是特别在意重量,扁带连扁带,或者扁带连C4/C3的钢丝环,在冲坠力不大的情况下,某些情况下也可以接受。但特别要注意的是这种连接方式绝对会对强度造成损害。
Conclusions
The sling-on-sling method of extending a cam sling does save the use of a biner but in my opinion is cumbersome for both the leader and the second. It also appears to reduce the ultimate strength of the system, however, in most cases not so much as to be the weakest link in a real-world climbing situation.
Bottom Line
When you’re extending a cam sling, use a biner and make everyone’s life a bit easier. If you’re a super light-and-fast type of guy, the sling-on-sling method works, but know that it does weaken the system. Also note that none of the tests we performed took into account possible wearing from rubbing and friction—possibly even reducing the overall strength of the connection even more. |
