  • Mining Shovel Roller Saddle Block
    Publication number: 20150078873
    Abstract: A mining shovel roller saddle block structure has first and second pairs of rollers which roll atop the shovel's dipper handles. Shafts mounted within the rollers are rotatably supported by block clamps fastened to shelves fixed atop the shovel's saddle blocks. Drop stops fixed to the shelves between the rollers extend over the dipper handles. Cables coupled between the block clamps and the drop stops retain the structure if it is dislodged by a collision with greenhorn protrusions on the dipper handles.
