In this blog post, we will explore the topic of screw jacks for large vehicle lifting. Screw jacks are mechanical devices used to lift heavy loads vertically. They are commonly used in various industries for applications such as vehicle maintenance, construction, and industrial automation.

What is a screw jack used for?

  • Vehicle lifting: Screw jacks are commonly used to lift heavy vehicles, such as trucks and buses, for maintenance and repair purposes.
  • Industrial applications: Screw jacks are used in industrial settings to lift heavy machinery and equipment for installation, repair, and maintenance.
  • Construction: Screw jacks are utilized in construction projects for lifting and supporting structures, such as bridges and buildings.
  • Automation: Screw jacks play a crucial role in automated systems, providing precise vertical movement for various applications.
  • Stage and theater setups: Screw jacks are employed in stage and theater setups to lift and adjust scenery, lighting, and other equipment.

What is the working principle of screw jack?

The working principle of a screw jack is based on the mechanical advantage gained by a threaded screw and a nut. When the screw is rotated, it moves through the nut, causing linear motion of the lifting mechanism. The pitch of the screw determines the amount of vertical travel achieved for each revolution of the screw.

Key points:

  • The rotational motion of the screw is converted into linear motion of the lifting mechanism.
  • The pitch of the screw determines the vertical travel achieved per revolution.
  • Screw jacks can provide high mechanical advantage and lifting capacity.
  • The lifting speed of a screw jack is relatively slow compared to other lifting mechanisms.
  • Efficiency can be improved by reducing friction and using lubrication.

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

A screw jack and a hydraulic jack are both used for lifting heavy loads, but they differ in their operating principles and characteristics.


  • Operating principle: A screw jack uses a threaded screw to lift the load, while a hydraulic jack uses pressurized fluid.
  • Force and speed: Screw jacks can provide higher lifting forces but have slower lifting speeds compared to hydraulic jacks.
  • Control: Screw jacks allow precise control of the lifting height, while hydraulic jacks may have more variable control options.
  • Maintenance: Screw jacks require less maintenance and are easier to service compared to hydraulic jacks.
  • Usage: Screw jacks are commonly used in applications where precise vertical movement is required, while hydraulic jacks are often used in heavy-duty lifting tasks.

How to choose or customize a suitable screw jack?

When selecting or customizing a screw jack, it is essential to consider various parameters and practical conditions to ensure optimal performance and safety. Here are some key factors to consider:

  • Load capacity: Determine the maximum weight the screw jack needs to lift, considering both static and dynamic loads.
  • Lifting speed: Identify the required lifting speed for the application, considering the desired efficiency and productivity.
  • Travel distance: Determine the maximum vertical travel required for the screw jack to meet the application’s needs.
  • Operating environment: Consider factors such as temperature, humidity, dust, and corrosive substances to select suitable materials and protection measures.
  • Mounting options: Evaluate the available space and mounting requirements to choose the most suitable screw jack configuration.
