Abstract
Panic bars are a machine operator-actuated control for the emergency deenergization of the tram motors on self-propelled, electric and diesel face equipment; including haulaqe equipment such as shuttle cars. There are nine basic types of panic bars (and several variations) that were recommended by The Bendix Corporation in the study contract that we performed for the U.S. Bureau of Mines, Pittsburgh Mining and Safety Research Center. All of the panic bars were characteristically of the "fire door" type that is frequently encountered on outside exit doors of many public and some commercial buildings. It was also the intent of the panic bar designs that, when emergency brakes are added to the face equipment machinery for which they are required, that they be designed and hooked up so that actuation of the panic bar will result in automatic application of the emergency brakes (immediately) following the deenergization of the tram motors).
