1. What is a screw jack used for?

Screw jacks have various applications in different industries. Some common uses include:

– Industrial machinery: Screw jacks are used to lift and position heavy machinery, such as conveyors and presses.
– Construction: They are used for lifting and supporting structures during construction or maintenance work.
– Automotive: Screw jacks are used in vehicle lifts and car maintenance equipment.
– Aerospace: They are utilized in aerospace applications for positioning and stabilizing components.
– Entertainment industry: Screw jacks are used in stage rigging systems for lifting and adjusting stage equipment.

2. What is the working principle of screw jack?

The working principle of a screw jack involves the conversion of rotary motion into linear motion. It consists of a lead screw and a lifting nut. When the lead screw rotates, it moves the lifting nut along its threads, causing the linear displacement of the load. This mechanism allows for controlled and precise lifting or lowering of heavy loads.

3. 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 differ in their operating principles and characteristics. Here are a few key differences:

– Operation: Screw jacks use mechanical force and a threaded screw to lift loads, while hydraulic jacks utilize hydraulic fluid pressure.
– Speed: Screw jacks have a slower lifting speed compared to hydraulic jacks.
– Load capacity: Hydraulic jacks can typically handle heavier loads compared to screw jacks.
– Maintenance: Screw jacks generally require less maintenance compared to hydraulic jacks.

4. How to choose or customize the right screw jack?

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

– Load capacity: Determine the maximum weight the screw jack needs to support.
– Stroke length: Calculate the required vertical or horizontal displacement distance.
– Operating speed: Consider the necessary lifting or lowering speed for your application.
– Environmental conditions: Evaluate factors such as temperature, humidity, and exposure to chemicals or dust.
– Mounting options: Choose the appropriate mounting configuration based on the available space and desired stability.
