■ Structure introduction
NSW hand brake consists of hand brake, drive shaft, gear, ratchet, clutch, box cover, bottom seat. The diameter of hand brake is 400 mm which is suitable for operation on flat train and other trains. Hand wheel is pressed with 4 mm thick steel plate, on which "braking" and "release" are stamped. The bottom seat and box cover are press-formed with 6 mm thick steel plate, on which nameplate and main technical specifications are provided.
Rotate the hand wheel clockwise as per the direction indicated on the hand wheel, so that chain can produce and maintain braking force.
Rotate the hand wheel counter-clockwise about 40°as per the direction indication on the hand wheel, so that hand brake can be released. The torque needed for release is about 50% of the input torque when braking.
Brake lock device is provided to avoid easy release of hand brake.
