How do the cars for metro
• How do the cars for Metro
During its long history, "Metrovagonmash" has accumulated a wealth of experience. In 1897, he was based as a car-building factory, then mastered the production of tracked vehicles, later in conjunction with AMO "ZIL" dump produced. Now Mytishchi "Metrovagonmash" - is the home of almost all subway cars Russia.
At the moment, the main activities of the company - is the release of metro rolling stock, rail buses production and repairing.
The main types metrovagonov currently produced are 81-714.5 / 717.5, 81-740 / 741 and 81-760 / 761.
Last year the company produced 243 subway cars, 32 rail-running buses, will repair 113 subway cars. And repairing plant in conditions preferred for the same cost of the repair install new equipment, not repaired old.
For the current year the Moscow Metro has ordered 320 cars. Large volume, and therefore it was decided to order the production of bodies on the Tver plant.
In the construction of the car leaving about 70 hours. The car starts with the body, it is made in the welding shop.
The shop reminds Rammstein clip. Under the ceiling of smoke, sparks around, roar, and all that is discharged and falls after the frosty air plant area.
This workshop - welding kingdom. Here, from the individual pipe, profile and sheet metal blanks skillful hands create the "body" of the car.
The metal is cut, fitted, secured on the stand and welded. Separately produced frame, roof and wall wagons.
Next comes the final assembly of the body, it is already possible to know the outline of the car.
Parallel fabricated bogies for wagons.
Then the body through transborder placed on parking tracks.
They are the body brought from Tver, they are completely packed in a white film.
Next, the body is primed and painted. paint shop combined with a workshop debugging.
Here the primed fiberglass body wear a mask. The product, though extensive, but relatively easy.
Further, color and applied paint wagons. Interior yet very unattractive.
Next painted body is transferred to the assembly plant.
The first workshop, which was for the production of cars had number 17 and now in his memory all the three-digit number of shops and end this figure.
The shop number 217 make installation of equipment on the body. The whole plant is filled with cars in varying degrees and for different subways. For example, right - the head coach - will leave for Kazan.
For ease of installation of the car body is raised on jacks. you can walk under it without fear - it is securely fastened.
The plant introduced "lean production". All parts are manufactured strictly in the required quantity, well thought out storage of parts, their availability and the ability to apply the desired part. Thereby minimizing the downtime of workers and equipment.
Located under the car engine control system, pneumatic system and battery units. Batteries are required to run the car after disconnecting it from the contact network, for example, during an overnight stay.
Parallel laid wiring and insulation.
In contrast to the "license" in new cars more intelligent electronics. Since asynchronous motors, they need AC power, and he was a regular in the contact system, so you need to install a so-called inverter. It allows not only to drive the motor, but also to recover energy during braking, returning to 50% of the electricity back to the grid.
Unfortunately, the Russian foreign cars more equipment. This quality requirement. The Russian partners can not offer the same cost-effective and reliable system like Europe.
The cars were designed for series 740/741 Butovo light metro line, so they are oriented to work in the open air, they, like buses, have a flexible joint and modern urban design. However, they have shown excellent performance and exploited and in tunnels, too.
In the "accordion" hidden cables, and itself "accordion" comes packed in foil.
After the end of the assembly and adjustment of the car becomes a finished look and lowered onto the cart. And on its wheels is sent to the coloring and debugging workshop.
In debug shop check the operation of all systems, and to finish dopodklyuchayut components applied lettering.
Check the dimensions of the car special frame.
One of the most important tests are running tests. At the factory there is a branch length is only a kilometer from the top of the contact network. To wagons could eat of it, the roof mounted pantographs, both on the train and connect the cables and hoses.
The plans "Metrovagonmash" build a separate plant acceptance of the finished product, it would allow the cars ready to put not in the assembly hall, and a separate room.
Life rail bus begins elsewhere. They are made in a separate building.
The main distinguishing feature of this type of transport - is the availability of a diesel engine, which allows travel on any railway line, regardless of electrification.
Appointment rail bus - it malozagruzhennye branches where there is no need for large diesel trains, they are often bought as a staff car. Boxer engine does not require a lot of space and is located under the floor, leaving a maximum of space for passengers.
A handsome plastic kit, streamlined shape and bright gloss paint make the RA-2 is very attractive.
In parallel, in the same shop going diesel train for Serbia. Total 12 dvuhvagonnyh compositions will be produced. In appearance they are not similar to any of the Russian train.
On the site of the bridge crane is perfectly visible orderliness and organization lean. All the details are in place, indicated by markings on the floor.
In the past, "Metrovagonmash" had almost a full cycle of production, but the complexity of the product and the market conditions have forced to transfer part of the production of specialized factories, it will improve the quality and reduce the cost of maintaining and upgrading of equipment in these shops. Sharply reduced molding and forging production, decreased the amount of work in the thermal workshop.
"Metrovagonmash" - a stable growing company, which provides an important mode of transportation modern high-quality and comfortable cars in Russia, CIS and some European countries.
