Surface Miners SEM SM55

Vermeer SM55 Surface Miner Machine Technical Specifications
Executive Overview & Operational Layout
A highly compact, high-efficiency surface miner unit optimized for continuous top-down cutting applications across production quarries, industrial open-cast mines, and large civil site preparations. Featuring a true one-piece haul footprint, this design facilitates easy roll-on/roll-off regional logistics without requiring complex teardowns or crane assistance. Outfitted with a zero-turn radius steering system and an ultra-low center of gravity, it relies entirely on a remote human-machine interface and automated GNSS line-by-line navigation, taking the operator away from heavy vibrations and noise.
