About this file
This document is a detailed engineering draft for a MALF (Multiple Articulated Lifting Frame) Assembly designed for the U.S. Army Corps of Engineers. The technical drawing consists of three sheets showing a complex mechanical assembly with multiple components, including a box frame weldment, main pivot assemblies, lifting arm assemblies, hydraulic mounts, horizontal supports, and bottom beam assemblies. The design specifications require strict material and welding standards, including ABS material certification, adherence to AWS welding codes, and comprehensive non-destructive testing (NDT) for critical welds, with 100% volumetric testing of critical butt welds and 100% surface testing of critical fillet welds. The assembly is 28'-1/2" long and appears to be engineered for precise integration with a revetment mat loading operation, specifically designed to work with a new robotic ACM (Articulated Concrete Mattress) laying barge scheduled for delivery in December 2025.
The detailed technical drawing (created by Marc Dickinson on 10/26/2022) provides a comprehensive exploded view and parts list, revealing 10 main pivot assemblies, 10 lifting arm assemblies, 5 hydraulic mount assemblies, 8 bumper spacer assemblies, 2 horizontal support weldments, 1 end alignment assembly, and 2 bottom beam assemblies. The drawing includes precise dimensional tolerances and notes emphasizing the critical nature of material certifications, welding standards, and non-destructive testing requirements. This draft represents a technical specification for manufacturing a specialized lifting frame system intended to support the U.S. Army Corps of Engineers' Regional Channel Improvement revetment sinking mission.
