What is a screw jack used for?

  • Load Lifting and Positioning: Screw jacks are primarily used for lifting heavy loads and precisely positioning them in industrial applications.
  • Industrial Automation: Screw jacks play a crucial role in various automated systems, providing accurate linear motion control.
  • Machinery Adjustment: These jacks are used to adjust the height, level, and alignment of machinery components for optimal performance.
  • Assembly and Testing: Screw jacks facilitate the assembly and testing processes by providing controlled linear movement during production.
  • Stabilization and Support: They are also utilized to stabilize and support structures, ensuring safety and preventing structural damage.

What is the working principle of screw jack?

The working principle of a screw jack is based on the mechanical advantage achieved through the rotation of the worm gear and the linear movement of the lifting screw. When the motor drives the worm gear, the lifting screw moves linearly, allowing the load to be raised or lowered. This principle enables precise control over the lifting height and ensures stability and safety during operation.

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 mechanical advantage through the rotation of the worm gear, providing precise control over linear motion. On the other hand, hydraulic jacks utilize hydraulic fluid and pressure to generate force, enabling faster and more powerful lifting. Additionally, hydraulic jacks require hydraulic systems and fluid, while screw jacks are mechanical devices that do not rely on additional components.

How to choose or customize the right screw jack?

  • Load Capacity: Consider the maximum load that the screw jack needs to lift and choose a suitable model with the appropriate load capacity.
  • Lifting Speed: Determine the required lifting speed based on the application and select a screw jack with the desired speed specifications.
  • Travel Length: Evaluate the necessary travel length or lifting height and ensure that the screw jack can accommodate the required distance.
  • Operating Environment: Consider the environmental conditions, such as temperature, humidity, and exposure to dust or corrosive substances. Choose a screw jack with appropriate protection levels and materials to withstand these conditions.
  • Mounting Options: Assess the available space and mounting requirements in your application. Select a screw jack with the appropriate mounting options, such as flange or base mounting, to ensure easy installation and integration.
