What is a Screw Jack Used For?

  • Lifting Heavy Loads:

    Screw jacks are often used to lift heavy loads, such as machinery or equipment. With a 12-ton capacity, they can handle even the heaviest loads with ease.

  • Applying Force:

    Screw jacks can also be used to apply force in pressing or pulling applications. They are commonly used in assembly lines and manufacturing facilities.

  • Precise Positioning:

    Screw jacks are useful for precise positioning of objects due to their ability to make small, incremental adjustments. They are often used in machinery and equipment that require precise positioning of parts.

What is the Working Principle of Screw Jack?

The working principle of a screw jack is based on the simple machine called a screw. A screw is a long, inclined plane wrapped around a cylinder. When the screw is rotated, it moves up or down the inclined plane, depending on the direction of rotation.

In a screw jack, a motor or hand crank is used to rotate the screw. As the screw moves up or down the inclined plane, it pushes or pulls a load attached to the jack’s lifting platform. The thread on the screw provides the mechanical advantage required to lift heavy loads with ease.

What is the Difference between a Screw Jack and a Hydraulic Jack?

Hydraulic jacks use hydraulic fluid to lift loads, while screw jacks use mechanical force to lift loads. Hydraulic jacks are typically more powerful and can lift heavier loads than screw jacks. However, screw jacks are more precise and can make small, incremental adjustments more easily than hydraulic jacks.

How to Choose or Customize the Right Screw Jack?

  • Load Capacity:

    Choose a screw jack with a load capacity that is equal to or greater than the load you need to lift.

  • Lift Height:

    Determine the maximum lift height required for your application and choose a screw jack that can meet this requirement.

  • Screw Type:

    Choose a screw jack with the right type of screw for your application. Acme screws are commonly used for vertical lifting, while ball screws are better for horizontal movement or precise positioning.

  • Material:

    Choose a screw jack made from high-quality materials that can withstand the conditions of your application.

  • Customization:

    If you cannot find a screw jack that meets your specific requirements, consider customizing one to fit your needs.
