Center Buffer Couplers CBC in LHB Coaches Unveiled: Part 1 various Parts..

‪@dltsicklinetanwar9388‬ (NDLSCNWSAATHI) Center Buffer Coupler (CBC) The coupler provides a means of mechanically connecting individual adjacent vehicles to make a train. The coupler is located at both ends of each vehicle. When connected to a coupler of an adjacent vehicle, it allows the vehicles to move independently to accommodate track curvature and elevation change while remaining connected (coupled) together. The coupler is opened manually using the coupler operating rod and is closed automatically when the couplers on adjacent vehicles are mated. The coupler automatically locks when fully mated. LHB coaches have been provided with tight lock centre buffer couplers instead of screw coupling. Couplers are AAR-H type and have anticlimbing features because of vertical interlocking. Couplers have adequate strength for:  Satisfactory hauling of a train of 26 coaches at 110 kmph  Satisfactory hauling of a train of 18 coaches at 160 kmph Coupling is possible under angular misalignment both horizontally and vertically. The coupler permits coupled trains to negotiate vertical and horizontal curves and allows rotational movements. The draw gear ensures cushioning effective in both buff and draft.
