Screw Jack Specifications

A screw jack, also known as a worm gear screw jack, is a device used to lift heavy loads or apply great forces. It is an essential tool in the industrial world, and there are specific specifications that one should consider when selecting or customizing a suitable screw jack.

What is a screw jack used for?

  • Heavy lifting equipment: Screw jacks are commonly used in heavy lifting equipment to lift large loads to a specific height.
  • Presses: Screw jacks are also used in presses to apply pressure to objects.
  • Adjustable height platforms: Screw jacks can be used to create adjustable height platforms for specific industrial applications.
  • Automation: Screw jacks are used in automation systems to move robotic components and other industrial machines.
  • Inclined conveyor belts: Screw jacks can adjust the height of conveyor belts that are inclined.

What is the working principle of screw jack?

screw jack

The working principle of a screw jack is based on the mechanical advantage of a screw thread. The screw thread is attached to a worm gear, which is driven by a motor. As the motor rotates the worm gear, the screw thread moves up or down, depending on the direction of rotation. This movement is translated into linear motion, allowing the screw jack to lift or move heavy loads.

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

The main difference between screw jacks and hydraulic jacks is the way they generate force. Screw jacks use a mechanical advantage, while hydraulic jacks rely on fluid pressure. Screw jacks are generally used in applications where precise control is required, while hydraulic jacks are used in applications where large amounts of force are needed quickly.

How to choose or customize suitable screw jack?

  • Load capacity: The load capacity of the screw jack should be sufficient to handle the heaviest load that will be lifted.
  • Lift height: The lift height should be appropriate for the application, and the screw jack should be able to lift the load to the required height.
  • Screw pitch: The screw pitch should be selected based on the required lifting speed and load capacity.
  • Safety: The screw jack should have proper safety features, such as limit switches and overload protection.
  • Environment: The screw jack should be selected based on the environmental conditions, such as temperature, humidity, and corrosive materials.
