Gearbox & Drop-Bottom Bin

Engineered a parametric 3D model of a 3-stop residential/commercial elevator system with a full hoistway structure, cabin interior, and top-mounted traction drive mechanism. Developed production-ready 2D drawings, sheet metal flat patterns for CNC cutting, and assembly documentation focused on structural integrity and smooth operation. You can also explore my other mechanical design projects featured in this post: Two-Stage Helical/Spur Gearbox: Full 3D parametric design, shaft loading calculations, and precise gear meshing layout. Drop-Bottom Waste Container: Heavy-duty dump bin equipped with a mechanical linkage/lever release mechanism for quick bottom discharge.
