Bucyrus International, Inc. 495HD Electric Mining Shovel
Shallow bank penetration of the arc of entry and rise is ineffective and inefficient. A shaving cut dribbles material into the dipper resulting in voids and making additional passes necessary while accelerating dipper lip wear. NOTE: A Deeper Bite = Quicker Fill Times
Digging should take place under the boom point for maximum shovel effectiveness. If necessary, the machine should be moved closer to the bank face, rather than extending the dipper handle. Reaching for material results in a partially filled dipper and excessive crowd and retract time. Use caution not to damage the boom point sheaves when operating close to the high wall.
