Worm drive jacks are mechanical devices that are used to lift heavy loads vertically or horizontally. They are used in a wide range of applications, including construction, automotive, and industrial settings, among others. In this guide, we will provide you with a comprehensive overview of worm drive jacks, including their working principle, differences from hydraulic jacks, and how to choose the right one for your needs.

What is a Screw Jack Used For?

Screw jacks are used for various purposes, including:

  • Lifting heavy loads vertically or horizontally
  • Moving heavy machinery
  • Adjusting the height of platforms and stages
  • Supporting structures during construction
  • Positioning equipment and machinery

What is the Working Principle of Screw Jack?

The working principle of a screw jack is based on the concept of a screw and nut. The jack consists of a screw that rotates in a nut, which is fixed to a load-carrying platform or a lifting arm. As the screw rotates, it moves the nut up or down, depending on the direction of rotation. This movement is then transferred to the load, causing it to move up or down.

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

The main differences between screw jacks and hydraulic jacks are:

  • Screw jacks are mechanically operated, while hydraulic jacks are powered by hydraulic fluid.
  • Hydraulic jacks are faster and more efficient than screw jacks.
  • Screw jacks are more stable and can hold heavier loads than hydraulic jacks.
  • Screw jacks are less expensive and require less maintenance than hydraulic jacks.
  • Hydraulic jacks are more portable and can be used in confined spaces.

How to Choose the Right Screw Jack?

When selecting a screw jack, it is important to consider the following factors:

  • Load capacity
  • Travel stroke
  • Lifting speed
  • Gear ratio
  • Input power
  • Environment

It is also important to consider whether a standard or custom screw jack is required. A custom screw jack can be designed to meet specific requirements, such as load capacity, stroke length, and mounting options.
