The main mechanism of the screw jack

Jacks are commonly used in industrial production, including screw jacks, hydraulic jacks, claw jacks, scissor jacks, and so on. Below, we will talk about the main mechanisms of screw jacks.

As a common and practical lifting tool, the internal structure of the screw jack contains exquisite design. Its main mechanism is the spiral transmission mechanism, which can be regarded as the core of the entire jack. This mechanism is ingeniously composed of screws and nuts. When the user rotates the handle, the screw begins to rotate, and the nut moves in a straight line along the thread of the screw. It is precisely with this simple yet efficient motion conversion that the screw jack can convert small rotational forces into powerful linear lifting forces, making it easy to lift objects weighing several tons. Its structure is compact and easy to operate, whether it is repairing heavy equipment in the factory workshop or adjusting the position of building materials on the construction site, the screw jack can show its skills.

Spiral jacks, with their stable and reliable performance, have become indispensable assistants in many industries, silently showcasing the unique charm of mechanical design and manufacturing in their work.
