在攀登过程中,绳结打法的对错和速度有时关乎性命,因此熟悉各种绳结的打法与其功能是极其重要的。绳结技术的掌握来自不断的练习,体会。初时可按图依样,然后离开书练习,甚至单手打出。每一个步骤都要非常正确,毫不含糊。要做到在黑暗中或其他各种条件下能自如打结,同时也应知道如何解开结,因为在许多危险时刻,不会解开结比不会打结更糟糕。所有的绳结在完成后都需收紧才能使用,同时绳端至少预留5厘米,以免意外松脱。


吊桶结(Barrel Hitch)


The 'barrel hitch', named for their use in hoisting cargo aboard ships, are a simple yet effective way to suspend an object. The barrel sling lays the barrel on its side, while the barrel hitch keeps it vertical. They work by forming a 'sling' around the object, which supports it from either side and underneath.


Warning: For stability, the rope encircling the barrel must be well above the center of gravity but far enough below the top to avoid slipping off. Also, care must be taken to ensure that the rope is properly centered under the barrel. With smooth and steady lifting, the Barrel Hitch provides reasonable security and safety.


方法

two methods: the first in which the Overhand Knot is spread open across the top of the barrel (1 to 8); and the second in which the Overhand Knot is laid out on the floor and then adjusted to resemble a figure 8 (A to E). In fact, one common variation of the second method uses an actual Figure 8 Knot laid out on the floor instead.


方法1(1-8)


方法2(A-E)
