Dec 22, 2017· Shoulder Ballast Cleaning Machine Working on Phulera to Rewari Railway Track. See the complete working procedure of the machine and learn that how railway works.
Jan 31, 2010· The fastenings shall not be covered with ballast. 7.9 Jointed track shall be fully ballasted so that the vertical faces of the sleepers, timbers or bearers are not visible. Ballast shoulders for jointed track should be level with the top surface of the sleeper ends.
TECHNICAL SPECIFICATION FOR SHOULDER BALLAST CLEANING MACHINE 1.0 GENERAL 1.1 These specifications are framed for a Shoulder Ballast Cleaning Machine (hereinafter called the machine), which should be capable of removing the ballast from the shoulder portion of the track, screen it, put back the screened ballast and profile it.
(3) In case of deep screening, assessment of ballast required for recoupment and providing standard section should be made by deep screening the ballast section to the full depth in a rail length for two to three sleepers at every V2 to 1 km. In this case screening is done under the sleepers as well.
The industry workhorse in shoulder ballast maintenance Loram's High Performance (HP) Shoulder Ballast Cleaner is the industry's proven performer for heavy haul, freight and commuter railroads. The Loram HP Series leads the Loram's High Performance Shoulder Ballast Cleaner (HP SBC) is the industry's proven performer.
As such, an investigation was carried out on track lateral resistance based on a realistic DEM simulation of STPT and a comprehensive sensitivity analysis on geometrical and mechanical properties of ballast layer. A test track in the Aprin railway station in the vicinity of Tehran city was prepared and several field STPTs were performed.
Furthermore, track ballast that is completely fouled can not be corrected by shoulder cleaning. In such cases, it is necessary to replace the ballast altogether. One method of "replacing" ballast, if necessity demands, is to simply dump fresh ballast on the track, jack the whole track .
Max.digging depth≥850mm(under railway surface) Screening efficiency: The cleaned ballast returned to the shoulders shall not exceed 3% fines when operating at the rated capacity of 1200m 3 /h with initial ballast bed contamination less than 30% fines. And the usable ballast contained in the waste shall not exceed 5% in weight.
This powder along with dust, sand ashes from locomotive form an impervious layer and prevent the ease flow of water through ballast. The ballast are constantly press in the formation. This reduces the quantity of the ballast and also the elasticity of the railway track is affected. The ballast is cleaned regularly by means of screening.
Deep Screening of Ballast . Deep screening of the ballast is done to ensure that a clean ballast cushion of the required depth is available below the lower half of the sleepers, which is necessary for providing the proper drainage and elasticity to the track.
A second consideration is the slope of the ballast shoulder away from the track, particularly on an embankment or where the ballast bed is raised above the natural ground so that the shoulder slope continues below sleeper soffit level. There appears to be no international consensus regarding the ballast shoulder slope. In Germany a slope
This is because as the ballast layer tends to deform, the grains are restrained by tension generated within the fibres. However, the biggest benefit in the tests carried out in the SRTF was obtained by reducing the slope at the edge of the mound of ballast on which the track sits (termed the "ballast shoulder").
the life cycle of ballast. A laboratory test procedure was developed to quantify the degradation ... degradation compared with 41% of the fouling material on the British Railway system being from ballast degradation (2). The portion of ballast degradation due to tamping has been studied previously with wide
SPECIAL SPECIFICATION 4391 Ballasted Track Construction 1. Description. This Item shall govern for the construction of ballasted track on constructed trackbed. Ballasted track construction includes, but is not limited to, placing ballast, distributing and lining ties, installing and field welding running rail, raising and lining track,
adequate lateral track stability with smaller ballast shoulder widths than those specified in Table 4.1. [8] The resistance to buckling forces may be enhanced by the provision of a ballast shoulder surcharge (windrow). [9] Use of the guidelines in this Clause will provide a design ballast shoulder .

Figures 6-1 through 6-7 show standard ballast shoulder widths and side slopes. In. finished or resurfaced track, the top of ballast may be up to 1 in. below the top of the tie, but never above. the top ...
A Loram shoulder ballast cleaning program ensures a healthy, robust railroad infrastructure maintained to deliver maximum ROI. Shoulder ballast cleaning consists of removing ballast at the end of the ties, separating and discarding fines and fouled ballast from reusable ballast and restoring the reusable ballast to the shoulder.
Adjustable ballast cleaning screen to allow aggregate size setting from 5/8-inch to 1-inch for screening material. Distribute returned ballast to either side of the track in tangent or curved track. Regulate/plow returned ballast to fit within standard track cross-section (capable

Similar to the laboratory studies, a 40 cm-wide ballast shoulder was implemented in the test track. The geogrid used in these tests was 4 m wide, and it was spread out along the required lengths as mentioned previously. Fig. 8 demonstrates the different parts of the test track along with the location of geogrids.
