Outlet Gates


Responding to the changing needs of the marketplace, Miner continues to innovate to help our customers move new products, re-purpose cars, or improve unloading performance. This is none more evident with our customers unloading cement. Our gate variations came about to respond to the multitude of unloading methods and unloading boot configurations. With over a century of experience, unrivaled commitment to engineering, state-of-the-art manufacturing and proven reliability, Miner’s AutoLOK™ II is the most widely specified outlet gate in the industry.

The AutoLOK II is easy to open and close and stays locked. It features Miner’s patented lost-motion mechanism system, which allows the door to unlock first without moving the door, reducing the risk of gate damage. AutoLOK’s slope sheets and vertical, below-door sides let the load flow freely without buildup or packing in the corners. With tight tolerances and full perimeter seals, the AutoLOK II prevents leakage–making it perfect for dry bulk commodity materials.

The AutoLOK II meets all GEAPS and AAR S-233-92 specifications to improve unloading operations in a wide variety of demanding applications.
