  • Industrial Machinery: Screw jacks are widely used in industrial machinery, such as conveyors, food processing equipment, and printing machines, to lift and adjust components.
  • Medical Equipment: In the medical field, screw jacks are used in hospital beds, operating tables, and other medical equipment for precise height adjustment.
  • Automotive Industry: Screw jacks play a crucial role in automotive assembly lines, allowing workers to lift and position heavy parts during the manufacturing process.
  • Construction: Screw jacks are used in construction projects to lift and support structures, providing stability and ensuring precise alignment.
  • Warehouse and Logistics: Screw jacks are utilized in warehouse and logistics operations for lifting and adjusting heavy loads, facilitating efficient material handling.

What is the working principle of screw jack?

The working principle of a screw jack involves the conversion of rotational motion into linear motion through the interaction between a screw and a nut. When the screw is rotated, it moves through the threaded nut, causing the jack to extend or retract, thus lifting or lowering the load. The mechanical advantage of the screw thread allows for precise control and heavy load capacities.

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

The main difference between a screw jack and a hydraulic jack lies in their mechanism of operation. While a screw jack utilizes mechanical force and a threaded screw, a hydraulic jack relies on hydraulic pressure to lift loads. Screw jacks offer precise positioning and are suitable for heavy loads, while hydraulic jacks provide quick and powerful lifting capabilities.

How to choose or customize a suitable screw jack?

When selecting or customizing a screw jack, several parameters and practical considerations need to be taken into account:

  1. Load Capacity: Determine the maximum load the screw jack needs to lift and ensure that the chosen model can handle the weight.
  2. Lifting Speed: Consider the required lifting speed and choose a screw jack with an appropriate gear ratio.
  3. Travel Distance: Determine the necessary vertical travel distance and select a screw jack with the appropriate stroke length.
  4. Operating Conditions: Consider factors such as environmental conditions, temperature range, and corrosion resistance to ensure the screw jack’s durability and performance.
  5. Mounting Options: Check the available mounting options and select a screw jack that can be easily integrated into the existing system.
