Climbing belay device is one of the most frequently used words in the climb. The perfect definition for the word Belay is to protect or to provide security. The most common use in case of climbing to safety to ensure a climber with a rope, harness and equipment investment. Taking the rope through the belay device as you climb, you ensure that sufficient friction. During a fall, the belayer friction increases until the fall, the rope and locking on one side to stop. This is safe climbing needs. Other sense are the related techniques for mountaineering climbing in common. The most common of these is to protect themselves. A new way of investing is passive protection climbing. A class of gear that climbers climb the rock to the rock anchor. Passive protection is generally no moving parts and does not scar the rock when it is placed on the gravel and some larger stone for the first time this principle. They were collected at the bottom of the cliff and wrapped with rope, as they were slotted into the cracks in the rock. Machine nuts played an important role in the development of climbing. Nuts used to secure bolts are machine nuts. These are often used in the construction of bridges and, except in the auto industry from a variety of other applications. An advantage of these notes is that the hole in the middle of the convenient loop the cord through them. One disadvantage was that, although they were by far the better alternative to the rocks, she rocks are often inclined. Modern passive protection was developed in the mid-1960s. They are called the nut and the hexagonal and they work on the same principle as its predecessors. You are light, compact and easy to remove from the crevices of the rocks. Top roping is a form of climbing is provided in which the safety of the climbers by a rope from the top of the rock lined. As the climber goes up the cliff, his partner starts at the other end of the rope through a friction device to draw. This method of ensuring the safety of the climbers as a backup. Spring loaded camming devices are the most advanced form of climbing standard. Very different from the passive protection and active camming devices to expand in order to be placed in the rocks, they come to fit in many different sizes and color coded for easy recognition. You have cracks parallel to the repair and use of equipment webcam. These devices are very useful when placed in a strategic position because it can hold much weight. “Friends” was the name of the camming devices, which were first introduced on a commercial basis. This introduction to a major impact in terms of climbing. Climbers were able to clear and cracks that otherwise were difficult to climb due to lack of support for placing protections to climb.
