The Mechanical Screw Jack, a precision-engineered lifting device, operates through manual effort by utilizing a screw pair mechanism where the screw or nut sleeve functions as the primary jacking component. Designed explicitly for heavy-duty applications, this mechanical jack supports loads up to 50 tons, making it ideal for lifting and supporting vehicles and heavy machinery in industrial and automotive sectors. The jack features a robust structure with a base plate of 165 mm and a head diameter of 142 mm, accompanied by a spindle size of 50 mm and bearing size of 16 mm. It has a closed height of 240 mm and offers a lifting capacity of 130 mm, balancing compact design with efficient lifting capability. The device relies on thread self-locking technology to securely support heavy objects, ensuring safety during operation, although it has relatively lower transmission efficiency and a slower return speed compared to powered jacks. This mechanical screw jack is perfect for professional workshops, automotive repair centers, and industrial environments requiring precise, reliable, and manual heavy lifting solutions.

The mechanical screw jack is designed to safely support vehicles or loads weighing up to 50 tons.
This jack uses a thread self-locking feature within the screw mechanism to securely hold heavy loads and prevent accidental descent.
The jack has a base plate size of 165 mm, head diameter of 142 mm, spindle size of 50 mm, and a closed height of 240 mm which are crucial for fitting and stability during operation.
It offers a lifting height of 130 mm, suitable for most heavy-duty vehicle maintenance requirements.
The screw jack has relatively low transmission efficiency and slow return, making it better suited for precise and controlled lifting rather than high-speed operations.
