Overview of Hand Wheel Screw Jack

Hand wheel screw jack is a type of mechanical screw jack that features a hand-operated wheel for easy and precise height adjustment. It is widely used in various industries, including manufacturing, construction, and transportation, due to its high load capacity and cost-effectiveness.

What is a Screw Jack Used for?

Screw jacks are used for a wide range of applications, such as:

  • Heavy-duty lifting and lowering of loads
  • Pushing and pulling heavy machinery and equipment
  • Leveling and aligning structures and machinery
  • Tensioning and compressing of mechanical components
  • Positioning and adjusting of workpieces and fixtures

Working Principle of Screw Jack

Screw jack works based on the principle of a screw thread. It consists of a threaded shaft, a worm gear, and a lifting nut. When the hand wheel is rotated, the worm gear turns the threaded shaft, causing the lifting nut to move up and down along the shaft. The lifting nut engages with the load, allowing it to be lifted or lowered with precision and ease.

Difference between Screw Jack and Hydraulic Jack

Screw jacks and hydraulic jacks are both used for lifting and lowering heavy loads. However, there are some key differences between them, such as:

  • Screw jacks are mechanical devices that use a screw thread for lifting, while hydraulic jacks use a fluid for lifting.
  • Screw jacks are more cost-effective, easier to maintain, and have a longer lifespan than hydraulic jacks.
  • Hydraulic jacks offer faster and smoother lifting, and can handle heavier loads than screw jacks.
  • Screw jacks are better suited for applications where precise positioning and control are required, while hydraulic jacks are better suited for applications where speed and power are required.

How to Choose the Right Screw Jack?

  • Load capacity and lifting height
  • Speed and travel distance
  • Environmental conditions and safety requirements
  • Mounting options and space limitations
  • Accuracy and repeatability
