The Langfab 4-Axle End Dump is built to move volume over long distances, in body lengths from 25 to 28 feet. Sides, floor and longsill are joined in continuous welds with no pause, which cuts the rust and corrosion that starts at weld interruptions. High-stress areas such as the hoist A-frame are cast in liquid metal, drawing on more than 45 years of Langfab experience in identifying and strengthening the points that fail first.
