1538 results about "Emergency brake" patented technology

On trains, the expression emergency brake has several meanings: The maximum brake force available to the driver/engineer from his conventional braking system, usually operated by taking the brake handle to its furthest position, through a gate mechanism, or by pushing a separate plunger in the cab a completely separate mechanism from the conventional braking system, designed to stop the train as quickly as possible a handle or plunger which may be applied by a passenger in an emergency situation, either operating the brakes directly or sending an alarm to the driver so that he can stop the train The emergency brake applies considerably more braking force than the standard full-service brake. The engineer, motorman or driver will only use the emergency brake as a last resort, since it may cause damage; even with modern wheel slide protection, a train may develop wheel-flats, and the rails themselves can suffer profile damage.
