07 Nov Types of ladders with a rope bowstring
A simple rope ladder, known due to the game of “Klondike”, has a wide range of applications. The device is used during the evacuation, carrying out the rescue operation or performing different types of work at height. Rope ladder is useful in the country house for servicing of wells or for the arrangement of the playground. Then we are going to talk about its characteristics and the methods of making it with your own hands, we will present thematic photo and video for clarity.
Rescue ladder for evacuation
Rope ladder is convenient due to the compact sizes and small weight. This allows you to easily change the place of evacuation. The rescue ladder has a long rope with no bars and a carbine designed for fixation. You don’t require specific skills to fasten it.
Rescue ladder with wooden rungs has a special flame retardant impregnation. Its stages are made from solid hardwood timber.
One of the models, which are used as a rescue ladder, has a label of LAN 10. It is also used in construction and for domestic purposes. Its length is 10 meters. In general, not only LAN 10, but any rope ladder must meet a number of standards:
- maximum length – 15 m;
- minimum width – 0.25 m;
- distance between steps – up to 0.35 m;
- the shape of the beams should provide convenient movement;
- availability of supports length from 0.11 m;
- maximum weight is 20 kg.
Rope ladder is used to evacuate the bedridden patients. Due to its help, a patient takes a sitting position, grasping it with their hands, and then returns to the starting position. The peculiarity of the device from LAN 10 for the evacuation of patients is the presence of 4-5 wooden bars and the use of the unstretchable rope for its manufacturing, calculated on the weight of 130 kg and above.
Kids’ ladder and the use of products from rope at home
Rope ladder may be an excellent trainer for a child. It is often a part of children’s sports corners. These classes help to develop a child’s coordination. If the kids’ ladder is hung vertically, the lower end of it should be fixed.
Such ladders as in “Klondike” are very convenient in everyday life: for climbing to the attic or cleaning wells. When folded, it occupies minimum space in the house; it is not difficult to find a place for its storage. You can make a rope ladder for servicing wells with your hands out of affordable materials.
Products for children should be quite safe
Rungs of the ladder can be done not only of wood but also of light metal alloys, plastic or of the same rope and string.
Materials for the manufacture of stairs with your hands
Initially, you need to prepare the rope. If you make stairs for domestic purposes of LVS type of 10 m length, the rope bowstring can be made from synthetic rope. It includes a nylon or dacron. This dependable rope string is used in the production of LAN rescue models; additional advantage is resistance to solvents and gasoline.
If you plan to make the product for a child, as in “Klondike”, it is preferable to take the rope on the basis of cotton fibers. Another suitable type of rope is sisal; it is made entirely from processed plant fibers. These types of ropes are used in various fields. However, they are more expensive than synthetic counterparts.
It is easy to calculate that for a ladder of 10 meters length would require approximately 10 × 2 meters of rope
In the case of steps, you can make crossbars out of wood. However, they are carefully polished to knots and other irregularities. This is necessary to prevent injury. If rope ladder, made, become part of the gameplay of the play set, a slat can be built by hand out of the rope itself (in this case, it can be not one but multiple series) or to buy ready-made plastic pieces. Another option is a bar of aluminum alloy.
When the rope string and other materials ready, you can watch the video and then proceed to practice. There are several options how to make a rope ladder, there is a simple algorithm:
- First, you need to prepare a bowstring and steps. Stepping back from the edge of the rails for about 7 cm, you need to make small gashes with a knife. The ends of the rope are scorched, so they will not be dismissed.
- You can now begin to mount the steps. Do it first from one side. The crossbar is fixed, tying knots “constrictor”. If you want to execute them, you should watch instructional videos and photos (above). Stepping back about 30 cm, make the knots and secure the next stage.
- When the first side is completed, move on to the second one. Thus it is better not to tighten the knots at once, you should first check the parallel arrangement of rails, and they should be similar in location of stair treads in houses.
After watching a training video, it will not be difficult for you to make a kind of LAN of 10 meters or more for use in the home. Share your finds how to tie a ladder with a rope bowstrings.
