The TRIZ 12-Ton Mobile Screw Jack is an electrically operated, heavy-duty lifting system designed for safe and efficient railway bogie and coach lifting applications. Each jack has a rated capacity of 12 tons (120 kN) and features a self-locking alloy steel Acme/Buttress screw mechanism that prevents load drop during operation. It offers a lifting stroke of up to 1600 mm (customizable up to 2000 mm), with a minimum claw height of 350 mm and a maximum height of 2350 mm. The structure is built with a robust fabricated steel column, phosphor bronze main load nut with steel backup nut, and a hardened checkered steel claw plate for secure grip. Equipped with retractable steel wheels for mobility and a VFD-based synchronized control system, the jack ensures smooth, precise, and safe lifting with overload protection and emergency stop features. It is ideal for railway maintenance depots and heavy industrial lifting applications.
