Innovation & Efficiency like never seen before By re-engineering our popular Self Dump Hopper line-up, our Tugger Bin Train line-up adds a new level of efficiency to any workflow for anyone from manufacturers to big operations. Each dump hopper has been given a durable ball and hitch and four 360˚ zero-point turn wheels so that tuggers can string multiple bins into a train and easily maneuver them through tight workspaces. Reduce your amount of dumping trips by carrying more volume at once or use the train to make a string of sorted materials mobile.
