This project focuses on the design, analysis, and simulation of a compact gearbox driven by a DC electric motor to lift a 3.0 kg load through 1.0 meter.

The gearbox was designed to meet the following engineering requirements:
High lifting speed while maintaining mechanical efficiency
Fail-safe operation, incorporating a ratchet or safety latch mechanism to prevent back-driving and uncontrolled descent during power loss
Compact gearbox packaging with optimized gear train layout
Modular motor integration, allowing quick attachment and removal from the gearbox casing
Single output shaft design, structurally analyzed to prevent excessive deflection and failure under load

The design process involved gear ratio selection, torque and power calculations, efficiency optimization, and 3D CAD modeling using SolidWorks. Structural considerations were applied to the output shaft to ensure load-bearing integrity, while safety mechanisms were evaluated to control reverse motion.

Key challenges addressed include size optimization, torque–speed trade-offs, safety integration, and mechanical robustness, resulting in a reliable and efficient lifting gearbox suitable for controlled vertical motion applications.
