Development of Mobile Base Screw Jack System for Vehicle Lifting

Abstract - Vehicle tire replacement using a conventional manual screw jack requires significant physical effort and time, which can be difficult for elderly people, women, and physically challenged individuals. To address this issue, this project presents the development of a mobile-controlled scissor screw jack system for vehicle lifting. The manual scissor jack is converted into an electrically operated system using a DC motor, motor driver, and ESP32 microcontroller. The lifting and lowering operations are controlled wirelessly through a smartphone application using Bluetooth or Wi-Fi communication. Power is supplied from the vehicle’s 12V source, making the system suitable for emergency roadside use. The proposed system reduces human effort, improves safety, and decreases lifting time compared to conventional jacks. This project offers a cost-effective, user-friendly, and reliable solution for modern vehicle lifting applications.
