Our modular Material Master Bulk Bag Unloader framework is constructed from continuously welded 4” square x ¼” wall carbon steel structural tubing, and features up to 78% more steel than other units for superior strength. Frames include 1½” square, continuously welded tubular cross bracing for maximum rigidity. MTS bolt flanges are round, and ½” thick for operator safety and easy assembly. These units feature a modular, three (3) section design that allows for simple installation and cost effective field upgrades in the event of future process changes. Units can be custom designed to meet your application requirements.
