screw jack

Screw jacks are widely used in a variety of applications, including heavy machinery lifting, positioning of large components, adjusting the height of platforms and tables, stabilizing objects during machining, welding, and assembly work. Screw jacks are particularly useful in situations where precise vertical movement is required, and where other lifting and positioning methods are not suitable.

What is the working principle of screw jack?

The working principle of a screw jack is based on the conversion of rotary motion into linear motion. The screw jack consists of a threaded screw that is attached to a nut. When the screw is rotated, it moves the nut up or down, depending on the direction of the rotation. This linear motion can be used to lift or lower heavy loads, and provides precise and reliable positioning of components and machinery.

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

The main difference between a screw jack and a hydraulic jack is the way in which they create force. A screw jack uses mechanical force to lift and lower objects, while a hydraulic jack uses fluid pressure. Screw jacks are typically used for lighter loads and more precise positioning, while hydraulic jacks are better suited for heavier loads and faster lifting speeds.

How to choose or customize the appropriate screw jack?

  • Load Capacity: Determine the maximum load capacity required for the application.
  • Screw Pitch: Choose the appropriate screw pitch, which determines the amount of linear movement produced per revolution of the screw.
  • Lifting Speed: Determine the required lifting speed, which determines the amount of time required to raise or lower a load.
  • Operating Environment: Consider the operating environment, including temperature, humidity, and exposure to chemicals or other corrosive substances.
  • Mounting Options: Choose the appropriate mounting options, including base mounting, flange mounting, or threaded mounting.
