What is a Lifting Jack Screw Type?


Lifting Jack screw type is a mechanical device that converts rotational motion into linear motion. It is commonly used in manufacturing and construction to lift heavy loads. The lifting jack can also be called a mechanical screw jack, worm gear jack, or a lead screw jack.

What is a Screw Jack Used for?

  • Industrial Applications
  • screw jack

    Screw jacks are used in a wide variety of industrial applications. They are used to lift, support, and position heavy machinery and equipment. Screw jacks are also commonly used in manufacturing processes such as assembly lines, material handling, and transportation.

  • Construction Applications
  • Screw jacks are used in construction for lifting and leveling heavy structures such as bridges, buildings, and towers. They are also used to raise and support temporary structures such as scaffolding and shoring.

What is the Working Principle of Screw Jack?

  • Rotational to Linear Motion
  • screw jack

    The working principle of a screw jack is based on the conversion of rotational motion of the worm gear into linear motion of the lifting screw. The worm gear is rotated using a handle or motor, which then turns the lifting screw. As the screw turns, it moves the load up or down depending on the direction of rotation.

  • Self-Locking Mechanism
  • Screw jacks have a self-locking mechanism that prevents the load from falling when the motor or handle is not in use. This makes screw jacks very safe and reliable for lifting heavy loads.

What is the Difference Between a Screw Jack and a Hydraulic Jack?

  • Power Source
  • The main difference between screw jacks and hydraulic jacks is the power source. Screw jacks are powered by manual rotation or motor, while hydraulic jacks are powered by hydraulic fluid under pressure.

  • Lifting Capacity
  • Hydraulic jacks have a higher lifting capacity compared to screw jacks. Hydraulic jacks can lift much heavier loads, while screw jacks are more suitable for lighter loads.

How to Choose or Customize the Right Screw Jack?

  • Load Capacity
  • The load capacity of the screw jack should match the weight of the load to be lifted.

  • Lifting Speed
  • The lifting speed of the screw jack should match the application requirements. If the load needs to be lifted quickly, a faster screw jack will be required.

  • Operating Environment
  • The operating environment of the screw jack should be considered when selecting the right jack. If the environment is harsh or corrosive, a screw jack made of stainless steel or other corrosion-resistant materials should be selected.

  • Mounting Options
  • The mounting options of the screw jack should be compatible with the application requirements. Some applications may require a screw jack with a flange, while others may require a screw jack with a baseplate.

  • Customization
  • If the standard screw jack does not meet the application requirements, custom screw jacks can be designed and manufactured to meet the specific needs of the application.
