1. Introduction to Cast Iron Screw Jack

The cast iron screw jack is a versatile mechanical device used in various industries for lifting, pushing, pulling, or positioning heavy loads. It consists of a cast iron housing, a lifting screw, and a worm gear mechanism, which allows for precise and controlled movements.

2. What is a Screw Jack Used For?

Screw jacks are commonly used for the following purposes:

  • 1. Load lifting and positioning in construction and industrial applications.
  • 2. Height adjustment in stage platforms, workbenches, and industrial machinery.
  • 3. Mechanical synchronization of multiple lifting points in heavy-duty equipment.
  • 4. Pushing or pulling heavy objects in material handling systems.
  • 5. Precision adjustments in scientific instruments and laboratory equipment.

3. Working Principle of Screw Jack

The working principle of a screw jack involves the conversion of rotary motion into linear motion. When the handle or motor rotates the worm gear, it engages with the lifting screw, causing it to move up or down. This linear motion allows the lifting or lowering of the load with minimal effort.

4. Difference between a Screw Jack and a Hydraulic Jack

Although both screw jacks and hydraulic jacks are used for lifting heavy loads, they differ in their operating mechanisms. Screw jacks rely on mechanical force and the rotation of a screw thread, while hydraulic jacks use hydraulic fluid and pressure to generate lifting force.

5. Choosing and Customizing the Right Screw Jack

When selecting or customizing a screw jack, consider the following parameters and practical conditions:

  • 1. Load capacity and required lifting force for the application.
  • 2. Desired lifting speed and travel distance.
  • 3. Environmental factors such as temperature, moisture, and corrosion resistance.
  • 4. Mounting options and space constraints.
  • 5. Safety features and additional accessories needed.
