What is a screw jack used for?

A screw jack is a mechanical device used to lift heavy loads in a vertical direction. It is commonly used in various industries such as construction, automotive, and manufacturing. With its ability to provide precise and controlled lifting, screw jacks are ideal for applications that require stability and safety.

What is the working principle of screw jack?

The working principle of a screw jack is based on the concept of a screw thread. It consists of a threaded rod and a nut that moves along the thread when rotated. As the nut moves, it pushes or pulls a load attached to it. This rotational motion is converted into linear motion, allowing the screw jack to lift or lower heavy objects with ease and precision.

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

While both screw jacks and hydraulic jacks are used for lifting heavy loads, they operate on different principles. Screw jacks use a mechanical system with a threaded rod, while hydraulic jacks rely on hydraulic fluid and pressure to generate lifting force. Screw jacks are generally slower but offer greater stability and load capacity, while hydraulic jacks are faster but may have limitations in terms of load capacity.

How to choose or customize the right screw jack?

When selecting or customizing a screw jack, several parameters and practical conditions should be considered:

  1. Load capacity: Determine the maximum weight the screw jack needs to lift.
  2. Travel distance: Define the required vertical movement range for the application.
  3. Lifting speed: Consider the desired lifting speed for efficient operation.
  4. Environment: Evaluate the working environment for factors such as temperature, humidity, and exposure to chemicals.
  5. Mounting options: Choose the appropriate mounting method based on the installation requirements.
