Fire trucks come out on the basis of a variety of stock cars. Special equipment is installed on their platform on the conveyor of special enterprises and necessary tools. However, the chassis of the hero of our story, the ZIL truck, was most widely used in Russia.

Advantages of the fire ZIL

So, why is ZIL on fire brigades:

  • The car is very unpretentious both in operation and in maintenance.
  • The machine can be used in a wide variety of weather and climate conditions.
  • The ZIL fire engine is a very maneuverable vehicle, which helps to put it in a place convenient for extinguishing.
  • When compared with other cars of this class, then one can immediately note the compactness of the ZIL. Why the car can drive even into relatively narrow spaces.
  • Unpretentiousness to the type and quality of the fuel being poured. Both gasoline and diesel variations are available, which can be replaced with gas equipment. The latter implies great savings on the maintenance of this official transport.
  • Spare parts, as well as the repair of this car, are relatively minor waste. Moreover, repairing ZIL does not require contacting specialized service centers- in most cases, a full-time team of auto mechanics can also cope with it.
  • A reasonable combination of cost and quality, which cannot be said about many other fire engines.
  • Sophisticated chassis design adapted to work in real conditions.

Average specifications

The most popular ZIL fire engines are the following models:

  • 2,5/40;
  • 3/40;
  • 3,5/40;
  • 4/40.

Let's take a closer look at the technical characteristics of special vehicles in the table. For example, we will use the classics of the ZIL-130 (fireman) lineup - A-40 (131).

Now let's talk specifically about model lines firefighters ZILs.

Model 130

The most common model of this fire fighting equipment- ZIL 130. More than 10 variants of the car were produced, the most popular of which was ZIL 130 AC 40 - 63B.

Let's look at distinctive features of this range:


Model 131

Developed in 1968, this series was also quite popular - it was produced in 1970-1984. There were two versions - 137 and 137A.

Let's go through the features:

  • The volume of the water tank is 2.4 tons.
  • Foam tank - 150 l.
  • Engine - 150 hp
  • Fuel consumption - 40 l / 100 km.
  • Unique water heating system due to exhaust gases.
  • Fire monitor control in manual mode. Range of water jet - 60 m, foam - 50 m.
  • Fire monitor rotation - +90 ... -20 degrees vertically.

Each of us has probably seen a red and white ZIL firefighter rushing to a call or returning to the garage. As we were convinced by the technical characteristics and the identified number of advantages of this machine, it will be in the service of the Russian fire departments for a long time - because of its versatility, unpretentiousness and full compliance with the conditions of the work performed.

To the means technical service includes fire fighting equipment, which includes fire engines, fire-technical equipment (PTV), as well as communications, lighting and other fire equipment. The main type of fire equipment are fire trucks (PA).

Depending on the purpose, fire trucks are divided into basic, special and auxiliary

Fire ZIL is considered the most common and efficient car in domestic fleets of the Ministry of Emergency Situations. He moves quickly, transports specialized devices necessary for extinguishing fires. Compared to other brands of fast response trucks, the vehicle on the ZIL chassis is unpretentious in maintenance, convenient in operation, adapted to different conditions, has good cross-country ability and maneuverability on difficult areas with a relative minimum of space.

Design

In device fire truck includes ZIL chassis and fire superstructures with the following equipment:


  • salon for combat crew;
  • pumps;
  • car stairs;
  • tanks for fire extinguishing materials;
  • compartments for fire-technical equipment (PTV).

A liquid tank is attached to the platform in the cradles, and a body is attached to the bracket consoles. In a solid metal cabin, there are 7 places for fighters and a driver. Behind the tank, a fire pump is built into the subframe. The mechanism is activated cardan shafts from the PTO on the gearbox.

The fire installation consists of a pump, a collector, a foam mixer and pressure valves. The compartment has a tank for foaming. The tanker is equipped with additional electrical equipment for lighting and signaling.

ZIL-130

The most common tanker is the AC-40-63B based on the ZIL-130 - upgraded version AC-30(130)-63A. Compared with previous model the capacity of the tank and the foam tank increased, the body became wider, decorative trims on the wheel arches were not installed, the pressure pipes were hidden inside and covered with hatches.


In the process of serial production of tanks, structural changes were constantly introduced. So, at first there was a “low skirt” in the cars, which formed wheel arch. Since the late 80s, no window was installed on the pump room door, then the back wall was straightened and no longer bent.

The design features of the modern fire truck AC-40-63B are as follows:

  • 2-row 4-door cab with panoramic windshield;
  • water tank - 2360 l and a foam tank for 170 l;
  • steel body with compartments for fire extinguishers and canisters for suction hoses;
  • single-level centrifugal pump PN-40UA rear position or single-stage normal pressure pump NTsPN-40/100;
  • fastening for the coil of sleeves RK-4A.

To increase the cross-country ability, arched tires are installed on the drive axle of the machine, and a winch is mounted on the bumper.

ZIL-131

AC-40(131)-137 has the following design:


  • improved 2-row 4-door cab with large rectangular windows in the doors;
  • the presence of an installation for heating water in the tank with exhaust gases;
  • petrol carbureted engine A-76;
  • centrifugal single-stage fire pump PN-40UV;
  • water-jet ejector-type foam mixer PS-5;

AC-40 (131) model 137 - fire truck on the chassis of an all-wheel drive truck ZIL-131. It is intended for delivery to the fire site of a combat crew of 7 people, fire equipment, water and a foam concentrate, as well as for extinguishing a fire with water from a tank, an open reservoir or a water supply network, air-mechanical foam using a foam concentrate brought or taken from an outside tank.

It was produced by the Priluksky plant of fire-fighting equipment from the old days (a prototype was assembled in 1968 in the same place). Since 1984, a modification of the AC-40 (131) model 137A has been produced, with a tank volume increased by 100 liters and fire monitor control from the cab. In 1983, a prototype machine ATs-40/3 (131) model 137A-01 was also produced with a combined pump PNK-40/3 with a coil and a barrel high pressure. This modification did not go into the series.

Mass distribution, kg:

The main means in the performance of fire and rescue work are specialized vehicles. In the USSR, similar equipment was created on the basis of trucks. The most massive were the ZIL, KamAZ and Ural chassis. IN countryside more often, cheaper and simpler fire trucks based on GAZ trucks were used.

General information

For many years, the ZIL plant was largest producer trucks in the USSR. The plant produced two types of trucks - ZIL-130 with rear wheel drive and ZIL-131 with all-wheel drive. It was these two chassis that were most often used to create special equipment.

It should be noted that the rear-wheel drive chassis was used to build tankers, and a more stable and universal chassis with all-wheel drive - for retractable car stairs.

Fire trucks are designed not only to extinguish fires in various conditions, but also serve to deliver the fire brigade. On board the machine there is a supply of water and a foaming agent, as well as a pumping unit with the possibility of supplying water from open reservoirs.

Tank trucks AC30(130)63

The first version of the fire engine on the new ZIL-130 chassis appeared in serial production since autumn 1965. The development and production of the machine under the designation PMZ 63 was carried out by the Priluksky plant of fire-fighting equipment. Some time later, according to new system designations, the car was renamed AC30 (130) 63. In the machine index, the letters АЦ denoted a tank truck, 30 - power installed pump in liters per second, 130 is the base chassis type and 63 is the model type. Subsequently, the factories in Orekhovo and Losino-Petrovsky began the production of machines with the same designation.

The combat crew of the car consisted of seven people, including the driver. The transported water supply in the tank is 2100 liters, the stock of foaming composition is 150 liters. The tank trucks were equipped with a portable motor pump MP 800A, a three-legged ladder and other equipment. The water pressure was provided using a pump model PN 30KF with a capacity of 30 l / s, however, there are machines of later releases with a pump with a capacity of 40 l / s. This was the ATs30 (130) 63A variant, which was equipped with a 40-liter pump PN 40U with increased productivity (this is what the letter “A” in the model designation spoke about). The plant in Priluki has been putting such a pump on the entire range of products since the late 60s. The range of a continuous stream of water reached 100 meters, when using a carriage, it was reduced to 60 meters.

The pump was driven cardan shaft from the power take-off. The number of revolutions of the ZIL fire engine could be controlled from the pump room.

Tank trucks AC30(130)63B

After some time, the AC40 (130) 63B machine went into production, which had a new chassis, cab and tank increased to 2360 liters of capacity. The capacity of the foaming agent tank was 170 liters. The new firefighter ZIL lost false wings on rear arches wheels. The configuration of the stern of the machine has noticeably changed - if previous version had an upbeat back, then new car she was straightened. Branch pipes of fire extinguishing systems were removed inside the body, access to them was carried out through hatches. A 150-horsepower carburetor engine made it possible to accelerate an almost ten-ton car to a speed of 90 km / h.

Fire ZILs of model 63B could be equipped with both old and new radiator linings. There is no clear time limit for the transition of cladding types.

Other versions of vehicles based on ZIL-130

In addition to tankers, there were other versions of the ZIL-130 firefighters. Among them, one can single out the AG-12(130)-PM-198 gas and smoke protection service vehicles and the AP 2 powder extinguishing installations. Such vehicles were used in the fire departments of large cities until the mid-90s.

Another type of ZIL fire trucks is autopumps. The most common was the AN30(130)64A pump, which began to be produced in the mid-60s under the designation PMZ-64A. The machines did not have a water tank, the supply of foaming composition was 500 liters. The machine was equipped with a three-legged ladder, oxygen cylinders and other fire extinguishing equipment.

Ladder AL30(131)L21

One of the most common firefighters ZIL-131 were ladders. The swivel base of the ladder was mounted above the rear chassis bogie. The stability of the machine was provided by four outriggers at the corners of the platform. The drive for turning and extending the stairs was carried out from the power take-off. To control the stairs, levers on the remote control, located along with the operator's seat on a swivel base, served. On the opposite side, a spare wheel was attached to the base.

The AL30(131)L21 machine was produced in the city of Torzhok from 1968 to 1983. The release continued later, but already under the designation AL30 (131) 506. The main difference was the lengthening of the ladder knees by 300 mm. Production cars until 1983 had a control panel with three levers, after the modernization of the levers there were four.

The maximum reach of the stairs up to 30 meters allows extinguishing in nine-story buildings. Three multidirectional spotlights are installed on its sections. When folded, it can be used as a crane arm. The machine was equipped with additional assault ladders.

Ladder AL30(131)506D

A modernized version of the ladder based on the fire ZIL-131. The main changes affected the nodes of the rotary part, hydraulic mechanisms and controls. To increase stability, the machine is equipped with a spring locking system. The mechanism consists of a hydraulic cylinder and a cable, which, when tensioned, blocks the spring of the rear bogie.

The hydraulic drive of the machine includes a power take-off, pump and filters working fluid, control equipment, main pipelines and oil tank. The car is equipped with a redundant emergency ladder drive.
