What is the speed drop

Quick descent, derived from the downhill protection technology of alpine adventures, was also used during rescue operations, transportation, and military raids. It later evolved into an extreme outdoor sports program similar to rock climbing and bungee jumping.

It has now differentiated into such categories as cliff drop, floor drop, bridge drop, and drop. The speed drop is under the guidance and protection of the coach. With the natural fall of the attraction, the rope is used to descend from the top of the rock wall. Participants can grasp the speed and landing point of the descent to reach the ground. The speed drop requires very strict operation and skillful techniques. At the same time, the participants must overcome the fear of height and speed and have the courage to go forward and persist in the end.

Basic technology:

The right hand is located on the right back side of the waist. Holding the tightrope can stop the body from falling. The right hand will relax at a uniform rate under gravity. Keep your upper body upright and your legs straight or slightly curved on the rock wall. Move down one step at a time. Except for your feet, do not touch any part of your body with the rock wall.

Basic equipment

Including safety helmets, seat belts, main locks, 8 word loops, static ropes, gloves, etc.

Safety Helmet: Like outdoor activities such as rock climbing, helmets are an indispensable safety protection device. A small stone falls on the way down, and it may cause great danger to life.

Seat belts: The seat belts used for downhill rides consist of belts and leg straps tied to the sides of the thighs. When you wear it, be careful to adjust the tightness, otherwise you will feel uncomfortable during a long period of decline. In addition, when you wear a seat belt, remember to wear a buckle. That is, the belt is fastened back in the opposite direction to prevent the belt from falling off.

Main lock: It is vividly called "Big D". The material is very strong and can generally withstand a force of 30 kN and a force of 10 kN. Mainly play a role in the connection, such as connecting flat straps, static ropes, usually connected to the "8" ring, buffering people's falling force. When fastening the main lock, be careful to loose half a turn in the opposite direction after threading to the head. This is done to facilitate the opening of the main lock to prevent lock-up after stress.

The “8” loop descender is the most commonly used descender. It increases the friction and controls the speed of descent through the 5 points formed by the shuttle passing through the 8 loops. When retracting the "8" ring, be sure to handle it gently. If the ring is cracked, use it even if it is small.

Gloves: Because of the quick drop distance and speed, the “8′′ ring is very easy to friction and heat, or even hot. Plus, holding a static rope to relax and tightening control the speed of decline, so a pair of gloves is essential. When falling, remember to keep the “8” ring away when holding the rope with both hands to prevent the glove from being caught in the “8” ring.

Static ropes: There are two types of ropes: the dynamic rope and the static rope. The static rope has a ductility of approximately 0. It cannot absorb the momentum by telescoping. It is generally used as a route rope and is often used for caving and tracing rivers. Basically not used for climbing, in particular, can not be made below the protection of the rope. The dynamic rope can absorb and release the impact generated by falling off, especially for the protection of the lower part of the system. In the project with the possibility of power falling, it is necessary to use a power rope, such as climbing, climbing, bungee jumping and so on. Static ropes are mostly white, even if they are colored, they are all monochromatic; the power ropes are mostly flower ropes and colorful. Static ropes are used in downhill sports.

Not prepared enough to take risks

In the face of absolute height and speed, any form of decline has room for exertion. Even if you don't have the ability to fly around, even if it is only a single rope, as long as you have enough courage and a strong heart, the rapid decline in the huge gap is not an "impossible task."

Standing in the air of 60 meters, vacating, descending, the whistling winds of the ears are in front of the rapidly passing rock wall, and there is only a rope with a diameter of 11 mm. Although we have professional equipment and technical guidance to provide a safe backing, but just close your eyes and imagine the scene of quick drop, people's feet have trembled and they have a fear.

So, this is a sport with certain risks and dangers. It is not fully prepared and warmed up. Do not try boldly! ! ! !
