Rescue ladders are auxiliary equipment, designed for urgent evacuation of people in emergency situations from high-rise levels of residential buildings. The rescue ladder is sufficient effective device for rescuing people in case of emergency from a height of up to 15 m.

Rescue ladder of hinged type, unlike others hand tools for this purpose, must be constantly stored in “standby mode” in a special box, near the provided permanent mounting points. In the event of an emergency, it must be ready for use in order to ensure the evacuation of people from the emergency zone.

Types of structures

According to technical design, the attachments are of the following designs:

  • rescue rope ladder- twisted bowstrings made from synthetic or natural materials; steps - wooden or metal;

  • cable car- bowstrings made of metal cable are used, rigidly connected to each other using wooden or metal crossbars;

  • chain- a ladder in which chain links are used as bowstrings, firmly connected into a monolithic structure;

  • tape- a device made of steel or synthetic tape;

According to the method of application they are divided:

  • stationary hanging stairs- stored in a special container inside the building and rigidly mounted in a designated place in the event of an emergency;
  • curtain wall facades- perform the same functions as previous structures, only they are stored and mounted outside, on the facade of the building.
  • heat-resistant design- designed for emergency evacuation of people from the area of ​​possible impact on the staircase structure open fire And high temperatures.

Models of fixtures

In this chapter we will look at the most commonly used designs, and in addition to this information, watch the video in this article.

Wire rope devices

The most popular and sufficient equipment on metal cables is the hinged rescue ladder USL “Chance”.

The product is made of refractory, heat-resistant material, with a standardized length of 6.0 to 30 m. The rigid design of the device will allow for the safe evacuation of people from the floors of a burning building.

The structure consists of the following elements:

  • galvanized steel cable Ø 5 mm is used as bowstrings;
  • round metal stepsØ 25 mm;
  • horizontal stops Ø 8 mm, fixing the device at the required distance from the wall of the structure.

Fastening is carried out using anchor devices pre-equipped on the walls of the building and carabiners installed at the top of the strings.

With a similar design and the same characteristics, there is another well-known device - the CCC hanging ladder (see photo).

Rope structures

To the class rope structures refers to equipment marked LAN or LNSP. The rescue rope ladder LAN can be used for evacuating people during fires in places where there is no open flame, during repair and construction work, and also as ancillary equipment on a personal plot.

Bowstrings are made of synthetic or natural material; steps can be made of wood or light aluminum alloy. To remove it from the walls of the building, the device is equipped with stops.

The strings of the ladder at the top, at a distance of 80 cm from the first step, are gathered together into a loop and secured with a carabiner. This makes it possible to use a single anchor to secure the structure or, in some cases, to use a winch to increase the lifting height.

The rescue ladder winch can be made in the form of a portable manual mechanism or be equipped with an electromechanical drive equipped with a gearbox. The second option is usually used by the mine rescue service in the coal industry (see photo).

Product characteristics:

  • step Ø 32 mm;
  • string - polyamide rope Ø 8 mm;

Operational Requirements

All the designs presented above, in special cases, provide for their use by ordinary citizens - with their own hands, without the participation of specially trained personnel.

Therefore, below are instructions and basic requirements for staircase systems of this type, which must be used when selecting and operating devices:

  1. All surfaces of attachments should not have sharp parts or burrs that could cause harm to health or create an obstacle for a person to move up the stairs.
  2. Overall dimensions must correspond to:
  • width - >250 mm;
  • length - no more than 15 m;
  • step pitch - 350 mm or less;
  • weight -
  1. The size and configuration of the cross-section of the steps should guarantee convenience and safety of movement. The recommended cross-section size of the crossbars is 26 mm or more.
  2. The steps must be positioned strictly horizontally and have a right angle with the surface of the bowstrings.
  3. Rope rescue ladders and other similar structures must be equipped with stops 110–220 mm long.
  4. The materials from which the equipment is made must ensure its trouble-free operation within the temperature range from – 40°C to + 40°C.
  5. The working life of the devices must be at least 50 cycles.

Tips: materials used in the manufacture of stairs must be corrosion resistant and covered with protective and decorative paint and varnish materials according to regulatory requirements for each specific material.

Test and control methods

Inspection of rescue equipment is carried out by the person responsible for fire safety object at least once every three months.

Control should be carried out according to the following parameters:

  • checking the packaging and completeness of the equipment;
  • presence of damage to the surfaces of the structure;
  • compliance with the standardized length;
  • width;
  • step size;
  • size and shape of crossbars;
  • weight of the device;
  • checking the horizontality of the treads;
  • presence and safety of stops.

More in-depth studies are carried out in the laboratory using special equipment:

  1. The residual deformation value is checked using a 150 kg load suspended on a selected step, close to the bowstrings, for 120 s. The deviation in the dimensions of the tested part should not exceed 2% of the width of the fixture.

  1. Shear testing of treads. A static weight of 150 kg is suspended on one side close to the bowstring. The test is considered successful if the steps withstood the applied load without changing shape or breaking the structure for 120 seconds.
  2. Resistance to high temperatures (for heat-resistant equipment). Tests are carried out in thermal chambers or on specialized stands. Heat-resistant suspended structures must be operational under the following conditions:
  • have a stable state for 180 seconds when the devices are exposed to a temperature of 600°C;
  • for 30 seconds - at a temperature of 450°C;
  • impact open flame- ensuring operability within 30 seconds.
  1. Strength test. The test sequence corresponds to the first point, with the exception of the static load, which in this case is equal to 360 kg. After the tests, the structure should not have tension, distortions, etc.

The rescue ladder must always be in working condition, characterizing the ability of the equipment to perform the assigned tasks, and its serviceability must comply with design and regulatory documentation in accordance with GOST 27.002-2015. The cost of violations in relation to the operation of this equipment is the disruption of the rescue operation and the death of innocent citizens.

Manual fire ladders LP, LSh, L-3k designed to lift firefighters to the upper floors of burning buildings, as well as to rescue people caught in fire in the premises of storey buildings.

Rescue fire rope VSP

Hanging rescue ladders "ССС" from 6 to 21 meters

The hinged rescue ladder "SSS" is designed for self-evacuation of people from premises in emergency and emergency situations, in case of fires, in case of exposure to aggressive environments, until rescuers arrive. A small-sized, simple and reliable rescue kit for evacuating people from buildings is provided in working position in minimal time.
Evacuation of people using the SSS rescue ladders does not require special training (transition to the use diagram):

For the manufacture of the hinged rescue ladder "SSS" (TU: 4854-001-23076997-99), crossbars from high-quality selected wood and high-strength polyamide cord (1450 kg tensile strength) were used. The components are treated with a fire retardant compound. Recommended length up to 15m. Work load 320 kg. Destructive load 1000 kg*. Must be equipped with special bags with identification stripes and instructions. During the last tests at a load of 1000 kg, there was no damage. Typical failure: shear of the crossbar under a load of 1200 kg without breaking the cord.

Rescue ladder

The hinged rescue ladder "LNS-00" (the number after the abbreviation means the length of the ladder in meters) provides the possibility of emergency descent of people from a window (balcony, loggia) of a building to the ground or to lower floors in the event of an emergency.

LNS delivery set: ladder, carabiner, bracket, stowage bag, passport. For an additional fee, a metal container is supplied for storing the ladder at the hanging location.

The staircase consists of two flexible strings (side ropes), made of galvanized steel rope, on which metal steps are fixed. At the top of the stairs, the bowstrings are brought together into a cable ending in a loop. This design allows you to attach the ladder with a carabiner not only to the standard fastening unit (bracket), but also to a suitable size load-bearing element of the building structure.

The stair treads have a traction-improving coating. The lower stage is colored (red or yellow) for easy hanging and folding of the LNS.

On some of the steps, plastic stops are installed at certain intervals, designed to remove the LNS from the wall, which increases the safety and convenience of people descending.
The bracket is mounted on the wall and is intended for hanging a ladder.

In standby mode, the ladder is in the folded position in a stowage bag or metal container.

The stairs are manufactured in 8 standard sizes.

Slip-Tow Truck


Slip-Tow Truck- a non-automatic device for descending from limited heights.

  • To work with a slip tow truck and bring it into working condition, two trained people (professional firefighters) are required.
  • The work of an untrained person with a slip tow truck is unacceptable.
  • The speed of descent on a slip tow truck is regulated from the evacuation zone (possibly the source of a fire) or by a person descending independently (there is a possibility of a person getting stuck in a smoky environment).
  • The descent on a slip tow truck runs along the line of windows, which increases the possibility of burns, damage from falling glass fragments, etc.
  • The device is not intuitive to use properly.

Model range of evacuation systems "Slip-Evacuator"

"OFFICE" model

A convenient and compact storage system in the table provides, if necessary, emergency self-evacuation. Specialized for self-evacuation of people who do not have their own suspension system(firefighter belt, rescue harness, etc.). The presence of a special rescue triangle in the system will ensure a comfortable descent. The descent control can be controlled independently or from the ground. Many buildings of the Russian Ministry of Internal Affairs are equipped with this system.

You choose the maximum descent height yourself. The system is placed in a shoulder bag.

Model "MINI SWING"

Designed for mass rescue. The model is specialized and especially suitable for use in self-evacuation and evacuation of groups of people (or individuals) who do not have professional skills.

Control of the kit is intuitive and accessible after familiarization with a minimum of required volume. Distinctive feature system is a uniquely low force (1-2 kg) applied during the control process. In this case, control can be carried out either by the person descending or by another person from the evacuation zone or from any place along the descent route, including the landing site.

The system is stored in a portable bag (backpack) and can be taken to a hazardous area if necessary. However, best option- permanent placement in proposed mass evacuation areas, equipped with special places for attaching the kit.

Model "COMPACT"

The "COMPACT" model is specialized for self-evacuation of professionally trained fighters of the fire and rescue service and other specialized units.

The kit is a means of individual use. In this case, it is assumed that the fighter has his own harness (fireman's belt, rescue harness, etc.) with a connecting carabiner.

The system uses a unique, specially designed working rope with a diameter of 7 mm, which has a “Kevlar” sheath, which provides increased strength, resistance to mechanical damage and abrasion, exposure to high temperatures, open fire, aggressive liquids, etc.
The kit is distinguished by its particularly small dimensions, allowing it to be worn on a belt or in a pocket of combat clothing, and weighing only 800 grams, which for the first time made it possible to provide every firefighter (rescuer) with a life-saving equipment.
At the Customer's request, the length of the working rope can be changed.

Model "SWING"

Specialized for use during evacuation large groups of people. It can be used for evacuation of material assets. The kit is a means of collective use and allows evacuation in a continuous-cyclic mode, combining the descent of a person (load) with the lifting of the suspension system, released after the descent of the previous person (load).

The kit is placed in a shoulder bag (backpack) and can be delivered to a danger zone if necessary or be permanently installed in advance in the intended mass evacuation areas. The system is controlled from the evacuation zone. The system has a wide range of applications on helicopters, oil rigs, in buildings, on decks of ships. It is mobile and easy to use, does not require additional funds for deployment and operation. Guaranteed operation of the system for at least 100 descents.

"ALPHA"- specialized, semi-automatic, with manual control carried out by the user, with the function of automatically stopping the descent when control is stopped or lost;

"KLUVIK" - universal type, with manual control continuously exercised by the user during the descent or, from the landing site, by the operator.

The system is placed in a shoulder carrying bag.

Self-rescuer Bars


Self-rescuer Bars is an automatic fire-rescuer device designed for emergency evacuation of people from buildings and other high-rise structures during a fire or other emergency.

  • To use a self-rescuer, no training or special skills are required.
  • The self-rescuer Bars does not require any adjustment (regardless of the person’s weight) and maintains a constant speed of descent.
  • During the descent of the first person, a second rescue scarf is lifted from the ground to descend the next one.

Technical characteristics of the self-rescuer:

  • the speed of descent on the self-rescuer is equal to the speed of the elevator and is 1 m/s
  • weight of the person being rescued up to 200 kg
  • descent height up to 300 m, at this moment You can use a self-rescuer to descend from the roof of any skyscraper in the Russian Federation.
  • the alerting time is no more than 60 seconds, even for an unprepared person.

To prevent the rescue of disaster victims from becoming another accident, the rope fire escape has a breaking weight of 1000 kg and is treated with fire-fighting substances. For quick descent or ascent, the set should be as light as possible, but at the same time durable. So that all people can safely descend to earth.

A rope ladder for evacuation is a reliable descent in a critical situation.

You can make such a staircase yourself; it does not require any expense or special knowledge. You will need wooden blocks and strong rope (rope). Take a rope from any material - linen, cotton or synthetics, it doesn’t matter. And the wood will have to be treated so that it does not rot and there is no fungus. The advantage is that you can choose what length you need and adapt it for different purposes. You can make one short one for children, a long one for chores. Work on the roof, in a well, for water transport– It will be useful to have a rope ladder everywhere. Its practicality and ease of use speaks for itself. It is not without reason that during evacuation this device is used for descents and ascents.
