  1. Translation motion: Screw jacks operate based on the principle of translating rotary motion into linear motion using a threaded screw.
  2. Rotary input: A motor or manual crank is used to rotate the screw, which in turn moves the load vertically.
  3. Screw thread pitch: The pitch of the screw determines the distance traveled per revolution, allowing for precise height adjustments.
  4. Self-locking mechanism: Screw jacks feature a self-locking mechanism that prevents the load from descending due to gravity when not powered.
  5. Load capacity: The load capacity of a screw jack depends on factors such as the size, material, and design of the screw and housing.

What is the difference between a screw jack and a hydraulic jack?

While both screw jacks and hydraulic jacks are used for lifting purposes, they differ in their operating mechanisms and applications.

  • Screw Jacks:
    • Operate using a screw mechanism.
    • Require less maintenance compared to hydraulic jacks.
    • Provide precise and controlled vertical movement.
    • Commonly used in heavy-duty industrial and construction applications.
  • Hydraulic Jacks:
    • Utilize hydraulic fluid and a piston to achieve lifting.
    • Offer higher lifting capacities.
    • Require regular maintenance and fluid inspections.
    • Find applications in automotive, manufacturing, and other industries.

How to choose or customize the right screw jack?
