About this file
The document is a set of four technical engineering drawings for mechanical components created by G2 Engineering Consulting, featuring detailed mechanical part designs for a potential U.S. Army Corps of Engineers project involving Articulated Concrete Mattress (ACM) lifting frames. The drawings include:
- MALF-100: Pin Retention Plate - A circular steel plate with multiple precision-drilled holes, made from ASTM A36 Steel, with a 3.500-inch diameter and specific bolt hole configurations.
- MALF-101: Bearing Retention Plate - Similar to the Pin Retention Plate, with a 3.500-inch diameter and 2.047-inch through hole, also manufactured from ASTM A36 Steel.
- MALF-102: Slotted Head Retainer - A complex curved component with multiple radii and angles, designed with intricate geometric features.
- MALF-103: Pivot Pin - A cylindrical component made from AISI 4130 Steel (normalized at 870°C), featuring a 2.375-inch diameter and specific threading specifications.
These technical drawings appear to be draft designs for mechanical components intended to support the U.S. Army Corps of Engineers' Regional Channel Improvement revetment sinking mission, specifically for the planned ACM lifting frames to be integrated with a new robotic ACM laying barge scheduled for delivery in December 2025.
