Optimized Design and Performance Evaluation of an Electrically Operated Automotive Engine Hoisting System
Abstract
This study presents the systematic design and evaluation of an electrically operated engine hoisting device for automotive workshops, specifically optimized for the Robin Hood vehicle's 193kg engine-gearbox assembly. Through rigorous conceptual analysis of three design alternatives (hydraulic, chain, and electrical systems), an electrically operated hoist with I-beam support structure was selected based on multi-criteria assessment incorporating safety (score: 8/10), performance (10/10), ergonomics (8/10), and cost-effectiveness (3/10). The final design achieved 66.7% assembly efficiency while meeting all operational requirements including 30° tilting capacity and 2kN lifting force. Computational analysis using CATIA 2015 validated the structural integrity of mild steel components, with buckling load calculations (via Euler's formula) confirming a safety factor of 2.3 at maximum capacity. Comparative testing demonstrated the electrical system's superior speed (1.5× faster than hydraulic systems) and precision (±5mm positional accuracy) during engine extraction. The Quality Function Deployment (QFD) analysis revealed 92% compliance with customer requirements, particularly in foldability (space reduction by 60% when stored) and operational safety (implementing dual locking mechanisms). These engineering advancements position the developed hoist as a technically superior and economically viable solution for medium-duty automotive repair facilities.
