NEED FOR ADOPTION OF BMBS
IN FREIGHT STOCK:

In order to overcome the problem faced in conventional bogie breakage, missing components and malfunctioning of SAB. In BMBS fitted wagons, BC is equipped with in built SAB.

In conventional BOXN/BCN wagons due to frequent theft of control rod, main pull Rod, End pull rod & Brake Rigging parts in tripling operation of wagons causing poor brake power in Rakes, resulting Detentions of wagons. In BMBS, wagons these Items are eliminated.

In order to Improve Mechanical efficiency of brake power.

In a Normal Rake of BOXN wagon Fitted with conventional type brake system there was around 18% Brake fading after a trial run of 1000 Km. But In case of BMBS fitted Rakes No brake fading is observed after around 5000 km Trial Run.

Braking distance of conventional Rake of 58 +1 wagons of BOXN is 1350 m. However in BMBS wagons it is 880 m (approx).

In conventional wagons setting of ‘A’ Dimension was a major problem. If any change made in sleeve nuts of E/L device that may create to heavy loss of wagon creating brake binding / wheel skidding. In order to overcome this, BMBS fitted wagons came into field which contains in built slack adjuster.

In case of BMBS system Automatic Load sensing Device is used which Gives 2.2Kg/cm2 Pressure to brake cylinder during empty condition 3.8 Kg/cm2 pressure during loaded for avoiding the above Problems.
