At first it seems that the need for the descent into the well shaft is not so great, but it's not quite true.

LAN: ladder rope rescue
This ladder plays a significant role in saving people. It can be used for the salvation of man from the mines of mineral resources and construction works, as well as extreme sports. One of the models rescue ladder - a LAN 10. It reaches more than 10 m in length.
The advantage of a rescue ladder is that it is characterized by low weight and simple construction
Rescue ladders are common options:
- The load - not more than 360 kg;
- Rope diameter - 0.8 cm;
- The width of the bars - 35 cm;
- The thickness of the foot - 3.2 cm.
Also escape ladder can be used for the evacuation, but you must know that the distance between the people on the stairs should not exceed 2 m. At the same time, you can evacuate up to 4 people.
The advantages of such a staircase are its light weight, which allows you to quickly change the evacuation site, it can also be mounted on the building structural elements, and requires special equipment necessary means of fastening and professional assistance.
Security Fire rope ladder
Fire stairs, as well as a rescue, is used for evacuation during fires, for emergencies, to rise to the high range, to exit the hazardous high-altitude areas. Included with the stair is a carbine, a hammer (to break the glass) and a bag. Such a staircase manufactured from a weakly combustible material (they are covered by the protective structure), and reaches a length of 5-19 m.
Before using the ladder in fact, necessary to carry out tests.
Check the rope ladder on the strength is possible by means of specially prepared test
During the tests on the bar and rope rope is strong static load. Ladder suspended, and by the middle of the lowest rungs attached load. If the ladder parts testing is not affected, then there is registration of the document on the results of the test. Later, on completion of inspection, the results are recorded in the act.
If the test results were not satisfactory, then the act is written notes with the recommendations, as well as the time of the follow-up audit. The very same ladder is removed from service.
How to assess the state of the structure:
- Evaluation of appearance: the presence or absence of deformed portions, damaged portions;
- As the connected fixtures and components - their reliability;
- Sharp edges, details of which can subsequently be traumatic;
- Stability of the structure, if it falls (is loose, damaged hooks), then, accordingly, its condition does not meet the safety requirements.
Spare parts for the rope ladder
Rope ladders are often used on ships. Rope nets are installed on the ship, and are raising the mast. They are also used in the equipment of the climbers, firefighters, rescue personnel.
Ladders must be sufficiently reliable and safe. It crossbar nodes are fixed to the rope.
To a rope ladder was sturdy and strong, you need to learn how to knit cable assemblies, which are fixed crossbar
There are several ways to mount:
- With the help of the node "Constrictor";
- With the help of site "eight";
- "Burlatskii loop" - knot.
Node "Constrictor" - to start knitting with the help of a ladder assembly "Constrictor", it is necessary to prepare the bar: to retreat from the edge of each crossbar of 5-7 cm, and making small incisions (deepening). This is done to ensure that the rope is not subsequently "went" on the stage, and indeed the ladder will be much stronger. Before knit unit itself must be treated with rope edge, so that it, in use, do not start to blossom, and only then knit rope puncture-proof assembly.
Node "eight" - preparations consist to at the same distance from each edge of the stage drill hole. The holes should be slightly larger than the diameter of the rope, its edge, as in the first case, you must also be treated. Provyazyvaem node "eight", and then introducing the rope into the opening stage. The very same stage must be secured in the correct position, two further loop is done by means of which provyazyvaem node.
"Burlatskii loop" or "knot" - there will not be rung. That rope will serve as stages of our stairs. However, this method requires some skill - the ability to tie knots.
Varieties rope ladder (video)
We adhere to a certain order of knitting: twist the rope so that it came from something resembling a figure eight. Then, pull the lower part of the loop, and then formed a circle, which later pulled the top of the loop, it is one that resembles a figure eight. Then fully tighten the knot. Thus, it is possible to make the number of nodes that need.
Successful ascents and descents!
