Screw jacks are essential devices in the manufacturing industry, designed to provide linear motion to heavy loads. These jacks are simple, efficient, reliable, and ideal for a wide range of applications. In this article, we will discuss the screw jack, its uses, working principle, differences with hydraulic jacks, and how to choose the right screw jack. We will also introduce HZPT, a leading manufacturer of screw jacks and other power transmission products.

What is a screw jack used for?

  • Heavy lifting: Screw jacks are commonly used to lift and support heavy loads. They are suitable for different types of equipment such as cranes, bridges, and even aircraft maintenance.
  • Load positioning: Screw jacks can position and maintain heavy loads such as steel plates, molds, and other equipment during manufacturing or assembly processes.
  • Load stabilization: Screw jacks can be used to stabilize loads that are prone to vibration or shock, minimizing the risk of damage or accidents.
  • Height adjustment: Screw jacks can be used for height adjustment in different types of equipment such as stage platforms, work tables, and lifts.
  • Clamping force: Screw jacks can provide clamping force to hold heavy equipment in place during machining operations.

What is the working principle of screw jack?

A screw jack is essentially a simple machine that converts rotary motion into linear motion, using a threaded rod and a nut. The principle of operation is based on the fact that the friction between the screw and the nut is higher than the friction between the load and the support. When the screw is rotated, the nut moves along the screw, causing linear motion of the load. The load is supported by a platform or a saddle, which moves up or down, depending on the direction of rotation of the screw.

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

A hydraulic jack uses hydraulic fluid to generate force, while a screw jack uses mechanical motion to provide linear motion. Hydraulic jacks are usually more powerful and faster than screw jacks, but they require hydraulic fluid, pumps, and hoses, which makes them more complex and expensive. Screw jacks are simpler, more reliable, and have a higher mechanical advantage, making them ideal for heavy lifting and load positioning applications.

How to choose or customize the right screw jack?

Choosing or customizing the right screw jack requires considering several parameters, including:

  • Load capacity: The screw jack should have a load capacity that is sufficient to lift and support the load.
  • Travel distance: The screw jack should provide enough linear motion to meet the requirements of the application.
  • Speed: The screw jack should operate at a speed that is appropriate for the application.
  • Environment: The screw jack should be suitable for the environment where it will be used, considering factors such as temperature, humidity, and corrosiveness.
  • Mounting: The screw jack should be compatible with the mounting arrangement of the equipment.
