What is the working principle of screw jack?

  1. The screw rotates, which causes it to move up or down.
  2. The lifting force is generated by the lead screw.
  3. The lifting force is transmitted to the load through a lifting nut.
  4. The efficiency of screw jacks is determined by the thread type, thread pitch, and the lubrication used.
  5. Screw jacks are used in conjunction with electric motors, hydraulic cylinders, or hand cranks for lifting and lowering.

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

A screw jack uses a mechanical screw to lift loads, while a hydraulic jack uses a hydraulic cylinder to lift loads. Screw jacks are slower and have a lower lifting capacity than hydraulic jacks, but they are more reliable and cost-effective. Hydraulic jacks are faster and have a higher lifting capacity, but they require more maintenance and are more expensive.

How to choose or customize a suitable screw jack?

  • Load capacity: Consider the weight of the load that needs to be lifted or supported.
  • Lifting height: Determine how high the load needs to be lifted.
  • Screw pitch: Choose the appropriate screw pitch for the required lifting speed.
  • Safety features: Look for safety features such as limit switches, overload protection, and emergency stop buttons.
  • Environment: Consider the temperature, humidity, and corrosive substances present in the environment where the screw jack will be used.
