BUCYRUS INTERNATIONAL, INC. 182M Electric Mining Shovel
GROUND PREPARATION Ground preparation is very important. The mining shovel requires a properly prepared ground base for operation. The crawler shoes must have full contact with the ground when the machine is digging. With the machine weight distributed over the crawler shoes minimum ground bearing pressure is obtained and the machine components are less stressed. For optimum operation, the ground supporting a mining shovel must be as near level as possible and firm. Sharp rocks and boulders cause point loading which will damage the propel machinery and crawler structures and should be removed if possible. Where this is impractical, cover the working area with fill dirt to a sufficient depth that will eliminate the effects of the rocks. The mining shovel design incorporates a calculated balance between boom length, boom angle, allowable dipper load, machine weight, and ballast used. During normal digging cycles, the center of gravity shifts from the front to the rear within a specific distance. If, for any reason, the digging radius or load increases to cause the center of gravity to extend beyond this specific distance the machine will become unstable. CAUTION:
Manual No. 10798
OPERATION OF AN UNSTABLE MACHINE COULD RESULT IN DAMAGE TO THE SHOVEL, TRUCKS OR SUPPORT EQUIPMENT.
