Purpose: Highly productive ballast cleaning machine of capacity up to 1200 cu.m/hr, for layering cleaned ballast on track with its fractionation and compaction of shear surface before laying of geotextiles or polystyrene foam plates and compaction of the first (lower) layer of cleaned ballast. The machine consists of three sections: Pull and energy section, extracting section and cleaning section. The pull and energy section is provided with a Cummins diesel generator of capacity 1125 kW Technical specifications Productivity, m3/hr, on cleaning with grasp width 5 m, depth of cut 0.4 m 1,200 By cut 800 Cleaning width, mm Maximum 5,200 Minimum 3,900 Cleaning depth below sleeper level, mm: Maximum 600 Minimum 400 Lateral tilt of cut, % ±5 Permitted track slopes during operation of machine with wagons for weeds, %: During fall 30 During rise 12 Weed content, remaining in ballast after cleaning, % 5 Grain size of ballast, returned to track 20 - 70 Distribution width of cleanable ballast lower layer, m 3-3,5 Thickness of cleanable ballast lower layer, m 0.1 – 0.2 Compaction degree of ballast lower layer 0.94 Lift of track skeleton by track skeleton hoist, mm 200 Shift of track skeleton by track skeleton hoist, mm ±350 Value of track reduction for one passage of machine with sufficient quantity of ballast, m up to 0.1 Deflection of track position from initial position after cleaning, mm ±5 Speed, km/h Low speed mode (operating) from 0.06 – 0.6 Transport on self mode and as part of train, km/h 80 Photo Video
