Electric jack with detachable remote control
A handheld electric jack includes a motorized screw drive mechanism housed within a cylindrical tool body, an actuating platform configured for linear motion, and a detachable control module operable in both docked and remote modes. The control module communicates wirelessly with the tool body and includes user interface elements for initiating lifting or lowering operations. The tool features safety interlocks, including dual-input activation, stall detection, and automatic shutoff. Load sensors and internal controllers enable responsive motor control based on sensor feedback. In some embodiments, multiple jacks wirelessly coordinate to perform synchronized lifting, monitor total load distribution, and respond to failure conditions. The modular platform accepts interchangeable lifting heads, and the system may be configured to operate autonomously or via user commands. This design improves safety, portability, and flexibility in construction, maintenance, and material handling applications.
