What is a screw jack used for?

  • Construction projects
  • Heavy machinery lifting
  • Stabilizing structures
  • Adjusting machine parts, such as molds or cutting blades
  • As a component in industrial equipment, such as conveyors, lifts, and presses

What is the working principle of screw jack?

  • Rotating the handle or motor turns the screw, which moves the load up or down by linear motion
  • The load is supported by the screw threads and the nut, which move together without slipping
  • The screw and nut can have different thread shapes and lead angles to vary the lifting speed, load capacity, and efficiency
  • The screw jack can be single or multiple, with bevel, worm, or helical gears to change the direction or torque
  • The screw jack can incorporate safety features, such as limit switches, overload protection, or locking mechanisms

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

  • A screw jack uses mechanical force to lift and lower the load, while a hydraulic jack uses hydraulic pressure
  • A screw jack is generally slower and less powerful than a hydraulic jack, but it can be more accurate and stable
  • A screw jack does not require external power or fluid supply, while a hydraulic jack needs a pump or compressor
  • A screw jack can work in a wider temperature and humidity range, while a hydraulic jack may need to be cooled or heated
  • A screw jack can be more compact and lightweight than a hydraulic jack, and can be easier to maintain and repair

How to choose or customize suitable screw jacks?

  • Load capacity: determine the maximum weight or force that the screw jack needs to support or lift
  • Lifting height: calculate the required vertical distance that the load needs to move up or down
  • Lifting speed: consider the desired speed of the lifting operation, which may depend on the application
  • Power source: decide whether to use a manual, electric, or pneumatic source to turn the screw
  • Environment: assess the ambient conditions, such as temperature, humidity, dust, or corrosive substances, and choose appropriate materials and coatings for the screw jack
