Outdoor climbing and lockdown and protector for technical equipment
Mountaineering lock
1. Uses and types
Mountaineering locks are one of the most widely used and used equipments in outdoor sports.
The main purpose of climbing locks is to connect climbing ropes with intermediate pivots. Climber can climb in lock-making and generation of many complex alternative trivial knot. Many combinations and use of seat belts, risers, and the like fall climbing equipment climbing locks have to rely on the link. The connector with protection point climbing rope, climbing and the like are connected to the main rope. Climbing locks are a guarantee of safety when climbing adventures and climbing rock walls .
In outdoor sports, climbing locks can replace ropes and are easy to use. At present, the climbing locks are mostly made of alloy materials and can withstand an instantaneous pulling force of 2000 ^-3000kg. The mountaineering locks purchased should be engraved with the words UIAA, which indicates that they have been certified by the International Mountaineering Federation.
Mountaineering locks can be classified into O-shaped, D-shaped, and pear-shaped locks depending on the shape. As this generally comes with three types of locks threaded, also known as the main town. In use, the threaded tighten to lock, providing security for those who climb.
2. Use caution
(1) Check the condition of the climbing lock before use. Check for cracks or cracks. Open and close openings should be smooth and free of obstructions.
(2) After hanging the mountaineering lock , turn the climbing lock opening downwards and outwards. The climbing lock is open to the rock surface. Friction or bump on the rock may be accidentally opened and dangerous.
Before (3) during climb or fall for protection, be sure to check that the locks on whether climbing.
(4) lock buckle climbing in the town of tight, you can go back a half turn after locking the basket, so as not to lock in shock.
(5) The rope is locked from the climber to the protector via climbing . It must be kept undistorted or not entangled.
Falling (protector)
The descender is in the process of lowering and protecting, through the friction between the rope and the equipment, to offset its own gravity or the impact of the fall, so that the operator can use a smaller force to control the speed of their own decline or to control the fall of the fall. One of the instruments. Single, light in weight and small in size, is a must for climbing.
I. Type
Commonly used drop protectors are "8" ring, ATC and GRIGRI. The principle is that the friction force can be used to offset the impact force so that the speed can be controlled at will.
(I) "8" word ring: It is the most common and most commonly used structural device for descending protection of such devices. The shape is like "8" and the structure is simple. "8" U-ring gives fast rope, and the rope runs smoothly. It is more serious that the rope is twisted. In addition to "8" cycloalkyl double rope decreases due to the frictional force is likely to cause too much inconvenience to the operation.

(2) ATC: It is a more commonly used protector and is lighter than the “8†ring. In use, a rope in the rope and cable through the ATC, to constitute a protection system. ATC's can be removed with the ring hole design on ice cord, particularly suitable for use on snow or ice.
(3) GRIGRI: It is a protector with self-locking device. It can use self-locking to achieve braking effect. When GRIGRI is subjected to high momentum, the internal gears will lock the master rope. When you lower it, simply pressing the lever gear will loosen the rope. The rope slides in GRIGRI to achieve the descent or protection.
The biggest feature of GRIGRI is that during the descent, the climber can loosen his hands holding the rope to perform other operations. However, GRIGRI cannot be used on Dengxue Mountain and ice climbing. It cannot be used after the rope is wet.
2. Use caution
(1) Before use, check whether the descender is seriously worn or if there is any crack. Before using the self-locking protector , it can be installed and forcefully pulled the rope to see if it can lock.
(2) before installation should be familiar with the use of the method of protection, the operation error is produced mainly dangerous.
(3) the direction of wear of the rope to the right. Do not drop the speed is too fast, the rope hand control of force appropriate, correct body posture.
(4) Don't throw and drop the drop device.
