|Joy Mining Machinery Globul Service Bulletin GSB0154|
Review of Joy Base Lift Circuit Design - Dated 11/29/2011
As a result of a fatal accident at the Century Mine in Ohio (USA) on August 8, 2011 involving a base lift jack, Joy has received a number of inquiries concerning whether or not our design is adequate.

In addition, as a reputable supplier of equipment and systems to the mining industry, Joy Mining Machinery wants to assure our customers that we routinely review and evaluate our products for safety compliance and performance. Therefore, the purpose of this Service Bulletin is to inform users of JOY equipment that such a review has been conducted on the JOY powered roof support hydraulic base lift circuits to verify that the circuit does not have any potential issues with respect to pressure intensification as a result of design or functionality.
|Hazardous 3rd Party Modified Circuit Breakers - Dated 04/21/2011
MSHA has been made aware of a hazardous condition that may exist in 600 volt and 1000 volt circuit breakers. This includes all frame sizes. The circuit breakers may appear to be new or rebuilt, but they have been changed from the manufacturer's original design. These mining circuit breakers, originally manufactured by Eaton Cutler-Hammer, may have been purchased either directly from the 3rd party or through a mining supply company. There is evidence that some of these circuit breakers have been modified by a 3rd party rebuilder with knock-off 600 volt and 1000 volt covers. The covers are of unknown construction and were not manufactured by Eaton. The labeling affixed to the breakers was also reproduced by the 3rd party rebuilder in an effort to make the circuit breakers look new and legitimate.
