A climbing net is a great tool on an outdoor playground. It's not easy as a kid to climb around in it. However, it is particularly important to have the right entanglements to hold the net together. They guarantee the children's safety when climbing and should therefore be checked regularly.
What is the function of a climbing net?
A climbing net expands the children's movement space. Children get to know their body better through this net and train muscles and their sense of balance. It also requires courage and trust to move on the shaky net. It is at some point demanding sport that is packaged as a game. In such a net the children don't get bored and always bring new play fun.
Learning knots - a short guide
Learning different entanglements for networks can be attempted in different ways. On the one hand there is the possibility to watch a video or read a manual and then try it with a piece of rope yourself.
On the other hand, someone who has already mastered the technology can show you how it works. The second variant is preferable. Because if you can't get on alone, and don't understand the instructions or the video, it will be difficult to learn the devouring. If you let someone show you the whole thing, they may have the opportunity to help you with mistakes or have some tips on how to make it easier.
There are also people who learn a devouring best by looking at the finished devouring and then thinking for themselves how the devouring is done. In such a case, however, you should have the finished devouring checked by someone who is familiar with this.
In order to be able to remember knots particularly well, it is sometimes helpful to think up a story about the entanglement and to connect each individual step with a certain point in the story. With most devourings, it is possible to knot them in different ways. In general, it can be helpful to be able to knot an entanglement in different ways.
Once you have understood the entanglements and can knot them yourself, the first step is taken. Nevertheless, one should practice the devouring regularly, until one masters it in the sleep. Since entanglements are often also safety nodes, they must also be traceable by external persons. This is why in climbing there is always the so-called partner check, which ensures that the partners check each other to ensure that they are properly secured.
It is precisely those devourings that are not often needed that need to be practiced regularly in order to master them in important situations or stress.
Check knots - safety first
Not only is knotting itself important, but it is equally important to be able to judge whether an intertwining has been properly knotted. This is very important for the aforementioned partner control. Therefore, when knotting, you should memorize how the individual interlaces look when they are finished.
When climbing together with others, one should always take a look at the partner's entanglement. When knotting the interlacing, it is not only the correctness of the knot that counts, but also the clean knotting. The rope strands should run parallel to each other, as this makes checking easier for the partner.
As a beginner you feel a little stupid checking the entanglements of people who have been climbing for years, but still you should do it. Even people who have a lot of routine can make mistakes. It is important not to be distracted when binding and knotting the gang and to check the whole thing again shortly before you start climbing.
What are the different knots?
Knots which do not form a fixed loop or sling and where the ropes run through the intertwining with each one-sided rope load are referred to as loose or sliding knots. Beginners usually don't understand why these are called devouring if they don't hold anything.
Half-mast design (HMS)
First the rope is laid through the mesh. The left rope end must be crossed in front of the rope end running out at the top. The front rope end running out of the mesh on the left is then guided past the other rope end.
Latch in the screw carabiner through the two parallel loop arches and screw in its fasteners.
The important thing is to test it to see if it turns. The rope ends are pulled alternately for this purpose. The node shape must change.
When securing with the HMS, the braking hand can be held over the karabiner or under the karabiner. With this devouring someone can also be roped down in case of need. When rappelling down the double strand, the rope strands lie parallel and are handled like a single rope.
In contrast to special safety devices, the HMS can be used in all situations to secure the climbing partner. A specially shaped HMS locking carabiner between rope and rope loop, central or fixed point serves as fixing carabiner for the HMS. When using the HMS, increased wear is to be expected due to friction, rope.
Reinforced half-mast design
The reinforced half-mast design is used for the release of heavy loads. An additional rotation of the rope compared to the simple half-mast design increases the braking force. This is caused by the additional deflection and the additional rope-on-rope friction.
You get a round trip by putting two eyes on top of each other, for example by wrapping an object completely so that the ends cross each other again. The protection against opening on pull can be done by further tying of half strokes, which fixes the loose knot.
At the binding knot, a firm, non-variable mesh is knotted. When climbing, binding knots serve to connect the rope with the climbing harness of the climber.
This is a cross lay with two parallel ropes. For a laid sack stitch, take the last piece of rope twice and make a crosscut.
For a bag stitch, first tie a crosscut about 1 metre from the end of the rope and then guide the end of the rope through the mesh or eyelet to be tied in. The threaded end of the rope follows the entanglements in the opposite direction.
After being entangled, all four rope strands must be individually tightened.
Depending on which side of the cross-strike one begins with the descendant, one receives a bag stitch in drop form or in ring form. The bag stitch in ring form is also used to devour ribbon loops. It is then referred to as the ribbon loop knot.
figure eight knot
During the trail, care must be taken to ensure that the rope strands run as parallel as possible, since the entanglement then holds better and is easier to release after loading. After knotting, all four rope strands must be individually tightened. After knotting, a laid figure eight knot can be attached to fixed points, rings, loops or eyelets using a carabiner.
The end of the rope running out of the double aft knot should not be less than 10 cm in length to prevent accidental opening. If necessary, a longer rope end can be neatly shortened by repeated half strokes or a cross lay around the load rope and provide additional safety against unintentional loosening of the knot.
This devouring is a variant of the aft knot. It is thicker than the figure eight knot due to its additional wrapping. However, it contracts much less under stress. Here it behaves like a bulin or double bulin. The comparable Bulin is however smaller from the dimensions, why this is preferred mostly. In the picture you can see the simple nine-knot.
The simple bulin holds reliably as long as the load occurs via the rope strand. However, it can be released under ring loading, i.e. with several unequal directions of force in the formed mesh. This can be done by additionally hooking carabiners into the ring, i.e. the mesh, of the bulin. This has already resulted in fatal accidents in climbing. Therefore: For safety reasons, the simple bulin must not be used as a binding knot!
