钩环

That said, screw gates are advisable on all top and bottom rope belays because the constant movement of the system could conceivably cause the rope to come out of an open gate krab.

就是说，带锁钩环适用於上方确保和下方确保，因为系统持续的动作相信会造成绳子脱出不带锁的钩环。

Few European climbers use locking krabs on belays, but in the UK, there is an almost paranoid reaction to using open gate krabs.

几乎没有欧洲攀岩者确保时会使用带锁钩环，但在美国，使用不带锁钩环就会引起很偏激的反应。

These hairline cracks sometimes develop over time in high-strength aluminum alloy and may reduce carabiner strength by more than 50%.

使用时检查钩环的开口附近是否有损坏，这些小破损有时候会出现在高强度的铝合金上，可能使钩环的强度降低50%，有裂缝或明显损坏的钩环应该丢弃。

Shape carabiners are stronger and lighter than ovals, given the same materials. The asymmetrical design ensures that loads are held off-center, toward the stronger, non-gated side.

型钩环的强度最强且比同材料的O形钩环轻，不对称的设计使负载物不会在中央，而移到开口的另一侧强度最强的地方。

Val-shape carabiners are the best choice for aid climbing, since the symmetrical shape holds loads at center of curve; runners wont's shift under load as they would in Ds.

型钩环是人工攀登的最佳选择，因为受力后绳环不会任意移动，在做钩环下降时最好选择这一型。

A competitor is in a legitimate position to clip a quickdraw either as long as his/her entire body has not moved beyond the karabiner at the lower end of the quickdraw in the line of the route, or as long as the competitor can clip the quickdraw without having to back climb along the line of the route.

选手应在身体之最低点高过快扣连结之最低钩环之前扣入钩环或是在无须延路线回攀的情况下扣入钩环。

D If a competitor clips the rope into a karabiner in accordance with Article 4.5.5 a above, but a 'Z-clip' has occurred, the competitor shall be permitted to un-clip and re-clip (if necessary, by down-climbing) the previous karabiner.

当选手依规则4.5.5条将绳索扣入钩环，如果发生Z型扣法时，选手得解开并重新扣入前一钩环。

If the consequence of the rope coming out of the krab would be catastrophic, a screw gate krab must be used; e.g. all attachments to the harness or single anchor points.

如果绳子脱出钩环的下场很凄惨，一定要用带锁钩环；例如所有连接座带的东西或是单一固定点。

Many climbing instructors use locking krabs when working and open gate krabs when playing. Why?

很多攀岩老师工作时使用带锁钩环，出去玩用不带锁钩环，为什麼这样？

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.
