1. Introduction

Screw jacks are mechanical devices used for seismic retrofitting in various industries. They are designed to provide stability and support to structures during seismic events, helping to prevent or minimize damage.

2. What is a screw jack used for?

Screw jacks are commonly used for:

  • Building and structural support
  • Heavy machinery leveling and stabilization
  • Bridge and highway construction
  • Industrial equipment positioning
  • Load lifting and balancing

3. What is the working principle of screw jack?

The working principle of a screw jack involves the conversion of rotational motion into linear motion. It consists of a threaded screw shaft and a worm gear mechanism. When the screw shaft is rotated, the worm gear engages with the threads of the screw, causing the linear displacement of the load or structure being supported.

4. 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 operating mechanisms. A screw jack uses mechanical force generated by the rotation of a screw shaft, while a hydraulic jack utilizes hydraulic pressure to lift or lower loads. Screw jacks are often preferred in applications requiring precise control and stability, while hydraulic jacks are suitable for heavy-duty lifting tasks.

5. How to choose or customize the appropriate screw jack?

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

  • Load capacity requirements
  • Travel distance and speed
  • Operating environment (e.g., temperature, humidity)
  • Mechanical interface compatibility
  • Safety features and overload protection
