About this file
This document is a draft engineering drawing for an Articulated Concrete Mattress (ACM) Lifting Frame, specifically the MALF-908 design. The technical drawing provides detailed schematics for a complex steel structural component with multiple views, including top, side, and isometric perspectives. The design appears to be for a specialized lifting frame used in revetment mat loading operations, featuring a rectangular top plate connected to angled structural components with precise dimensional specifications.
The drawing specifies the material as ASTM A Grade Steel, with critical welding requirements including volumetric and surface non-destructive testing methods. Tolerances are tightly controlled, with angular machining to specific degrees and decimal place precision. The draft is created by Marc Dickinson from a engineering and consulting firm, and marked with multiple revision indicators, suggesting an iterative design process for a specialized piece of equipment intended for use in U.S. Army Corps of Engineers channel improvement and revetment sinking missions.
