06 Feb Types of ladders with a rope bowstring
A simple rope ladder, known for the game “Klondike” has a wide range of applications. The device is used during the evacuation, and during the rescue operation or performing different types of work at height. It is convenient when servicing of wells, for the arrangement of the Playground. Then we will talk about its characteristics and the methods of making it with your own hands. We will present thematic photos and videos for clarity.
Rescue ladder for evacuation
Rope design is comfortable 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. Fastening with hands does not require specific skills.
Rescue ladder with wooden rungs is a special flame retardant impregnation. Stages are made from solid hardwood timber.
One of the models, which is used as a rope rescue has labeled LAN 10. It is also used in construction and for domestic purposes. Its length is 10 meters. In general, not only the 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. Such patients can take a sitting position, grasping it with their hands, and then return to the starting position. The difference of the devices for the evacuation of patients from LAN 10 is the presence of 4-5 bars of wood and use of unstretchable rope, calculated on the weight of 130 kg and above.
Baby steps and the use of products from rope at home
Rope model may be an excellent trainer for the baby. It is often a part of children’s sports corners. These classes help develop a child’s coordination. If the baby ladder is hung vertically, its lower end should be fixed.
Stairs, as in “Klondike”, are very useful in everyday life: to climb to the attic or clean the wells. When folded they occupy a minimum of space in the house, it is not difficult to find a place for storage. You can make a rope with you own hands for servicing wells.
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 own hands
Initially, you will need to prepare the rope. The ladders for domestic purpose by type of LVS will do with rope of the length of 10m made from synthetic. It includes a nylon or dacron. This dependable rope string is used in the production rescue models LAN, additional advantage – resistance to solvents and gasoline.
If you plan to run the product, as in “Klondike”, for a child, it is preferable to take the rope on the basis of cotton fibers. Another suitable type of rope – sisal, they are 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 a ladder of length of 10 meters would require approximately 10 × 2 meters of rope.
In the case of steps, you can make a crossbar out of wood. However, they are carefully polished to knots and other irregularities. This is necessary to prevent injury. If a rope ladder becomes a part of the gameplay of the play set, a slat can be built with your own hands out of the rope itself (in this case, there can be not one but multiple series) or you buy ready-made plastic pieces. Another option is a bar of aluminium alloy.
A simple algorithm of work
When the rope string and other materials are 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. Step back from the edge of the rails about 7 cm, and make small gashes with a knife. The ends of the rope are scorched, so it will not be dismissed.
- You can now begin to mount the steps. Do it first with one hand. The crossbar is fixed, tying knots “constrictor”. To execute them, view 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 delay the nodes at once, first you should check the parallel arrangement of rails. They should be similar in location to stair treads in the house.
After watching a training video, you can make a kind of LAN for 10 meters or more with your own hands. Share your finds how to tie a ladder with a rope bowstrings.
