Graham-White proudly introduces the SafeSet Locomotive Parking Brake. SafeSet is an automated electric motor driven system that also incorporates the standard manual interface found on lever style hand brakes. The primary operator interface is a control panel incorporating two push buttons: SET & RELEASE. In the event electrical power is unavailable, the operator simply uses the manual levers. In the manual mode of operation, SafeSet only requires 60% or less operator-input force than existing mechanical hand brakes. Graham-White's paper and fully functional demonstration unit were enthusiastically received at both the 2000 RSA and 2004 RSI shows in Chicago. Contact Graham-White for a free copy of either papers and to learn more about this exciting advancement in locomotive braking solutions.
