History of the Railway Sleeper:

 

    In 1877, Joseph Monier, a French gardener, s ested that concrete reinforced with steel could be used for making sleepers for railway track. Monier designed a sleeper and obtained a patent for it, but it was not successful.

 

    Concrete sleepers were first used on the Alford and Sutton Tramway in 1884. Their first use on a main line railway was by the Reading Company in America in 1896.

 

     Designs were further developed and the railways of Austria and Italy used the first concrete sleepers around the turn of the 20th century. This was closely followed by other European railways.

 

    Major progress was not achieved until World War II, when the timbers used for sleepers were scarce due to competition from other uses, such as mines.[1] Following research carried out on French and other European railways, the modern pre-stressed concrete sleeper was developed.

 

    Interest in concrete railway sleepers increased after World War II following advances in the design, quality and production of pre-stressed concrete.

 

Until now, a huge improvement on concrete sleeper. 

Railway Sleeper Includes:

 

Common  sleeper:  Used in  single-chord , station lines laid

Switch sleeper:Used in build  switch area

Bridge sleeper:Used in bridge deck line laying

At present, Chinese standard railway gauge is 1435 mm

 

Concrete sleeper type	Width(mm)	Thickness (mm)	Length(mm)	Note
Common  sleeper	220	160	2500
Switch sleeper( common)	220	160	2600~4850	Carry 150 mm . Total about 16 specs for length
Switch Sleeper (standard)	240	160	2600~4800	Carry 200 mm . Total about 12 specs for length
Bridge sleeper	220	240,260,280,300	3000

 

The Definition of Rail Sleeper Mould:

Rail sleeper mould is the foundational machine of the railway track laying. And it’s also an important and indispensable machine for the upper rail construction.   It’s used to prefabricate cement and concrete cover plate fabrication in building railways.

 

Automatic Railway SleeperTensioning Machine:

Automatic concrete sleeper tensioning machine (ATM-300) is dedicated equipment designed for sleeper production line.   It is mainly composed of tensioning jack, sensors, human-computer interface, PLC, console, tensioning car and oil pump station. The system has high reliability, high control precision and the large capacity of data storage, query convenient, work fast, simple operation, easy maintenance, etc advantages.

Concrete Railway Sleeper Feeding Machine:

 The concrete railway sleeper feeding machine composed of frame, hanger plate subassembly, hopper, hopper door opening mechanism and walk mechanism etc.

 

 

parameters

1.Railway gauge: 1750mm

2.Capacity:  3m3

Railway Sleeper Vibration Table:

1.     The first stage is the mould need to vibrate in the vibration table about 2-2.5min called common vibration. The main function is to make the Concrete vibration close-grained and bleeding. Meanwhile to flat ash. Let the concrete quantity same in the 10 sleeper model.

2.     The second stage is the mould continue to vibrate in the vibration table.  Meanwhile put the Embossing cover plate on the top of the mould and hold the sleeper subface concrete.

 

 

Technical parameters:

1.Frequency: 1500times/min

2.Amplitude:0.5mm

3.Total Vibration Force(Adjustable) : 667Kg

4.Motor Power : 37-45KW

Roll over machine for railway concrete sleeper:

The railway concrete sleeper mould rolling over by special equipment. The concrete sleeper appears displacement between models because being released,Cut the adhesive force between concrete sleeper and mould, when the model on the machine turn 180 °the wire connected to the two rows of 5 root sleeper can demouldsmoothly and into the finished  productroller way to continue to the next working procedure. Roller over machine also make railway concrete sleeper by backwards into a positive direction.

 

Specifications:

1.Speed of corbel: priority selection 2R/min.

2.Motor power: >22KW.

3. Motor type: double ended machine.

4.Fasteningtype :hydraulic lock.

5. Flip type: Mechanical turnover.

Professionstacker crane machine for concrete sleeper:

When the concrete sleeper product from the end of the workshop into the open-air finished-parts storage. There are two types of stacker crane: One increase swing and retractable guide frame rigidity on the basis of lifting car,other one rigid guide frame fixed on the lifting the car. Sleeper move transversely device and crane  served concrete rail bearing transport from one side of the workshop to outdoor finished-parts storage. Cut the steel wire between concrete rail bearing sleeper in finished product transportation roll. Move the concrete rail bearing to cross rail outside then transport tostocking yard by crane and car.

Roller Way For Concrete Sleeper:

 

As a important and effective production machine for concrete sleeper , concrete sleeper roller way is used for transport concrete sleeper mold to different directions during production process .  Concrete sleeper production adopt Assembly line process,mold Use cranecome in and go outsteam pool,others are transmitted by roller. The application of roller effectively reduced the output of labor,enhance the automation of the whole process. Production more efficient and accurate.
