A screw jack is a mechanical device used to lift heavy loads or apply great forces with a relatively small effort. Among various types of screw jacks, the Pittsburgh 3-ton floor jack set screw is one of the most popular due to its high durability and load capacity. In this article, we will discuss what a screw jack is, its working principle, the difference between a screw jack and a hydraulic jack, and how to choose or customize a suitable screw jack. We will also introduce our company, HZPT, as a leading manufacturer of screw jacks and other transmission products.

What is a screw jack used for?

  • Heavy load lifting: Screw jacks are commonly used to lift heavy loads found in manufacturing, construction, and transportation industries. The Pittsburgh 3-ton floor jack set screw can lift up to 3 tons of weight with ease.
  • Force multiplication: By leveraging the rotational motion of a screw, a screw jack can multiply the input force to generate a much higher output force. This is useful in applications where a small force needs to be applied with great precision.
  • Height adjustment: Screw jacks are often used for precise height adjustment of workstations, platforms, and machinery. The set screw of the Pittsburgh 3-ton floor jack allows precise height adjustment.
  • Stress testing: Screw jacks can be used to apply a controlled amount of force on a testing object to measure its resistance to stress.
  • Emergency rescue: Screw jacks can be used as a last resort to rescue people trapped in cars or buildings by lifting heavy debris.

What is the working principle of screw jack?

A screw jack works based on the principle of the inclined plane. When a force is applied to the handle of the screw jack, the handle rotates the screw shaft, which moves the load up or down depending on the direction of rotation. The distance the load travels is proportional to the pitch of the screw thread, the circumference of the screw shaft, and the angle of the inclined plane.

The screw jack also takes advantage of the self-locking property of the screw thread, which means that the screw will not move unless a force greater than the load force is applied. This makes the screw jack a safe and reliable lifting device.

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

While both screw jacks and hydraulic jacks are used to lift heavy loads, there are several differences between them:

  • Power source: Screw jacks are manually operated, while hydraulic jacks require a hydraulic power source to operate.
  • Precision: Screw jacks are more precise in terms of load positioning due to their fine thread pitch, while hydraulic jacks are better for quick lifting due to their higher lifting speed.
  • Maintenance: Screw jacks require less maintenance than hydraulic jacks due to their simpler design and lack of hydraulic fluid that needs to be changed or replaced.
  • Load capacity: Screw jacks have a lower load capacity than hydraulic jacks due to their mechanical design, but they are still capable of lifting several tons of weight.

How to choose or customize a suitable screw jack?

When selecting or customizing a screw jack, several parameters need to be considered:

  • Load capacity: Determine the maximum load the screw jack needs to lift and choose a suitable model based on the load capacity. The Pittsburgh 3-ton floor jack set screw is suitable for lifting loads up to 3 tons.
  • Lifting height: Determine the maximum and minimum lifting height required for the application and choose a screw jack with an appropriate stroke length.
  • Speed: Determine the speed at which the load needs to be lifted and choose a screw jack with a suitable thread pitch and handle length.
  • Environment: Consider the environmental factors such as temperature, humidity, and dust level to choose a screw jack with suitable sealing and lubrication options.
  • Mounting: Determine the mounting options required for the application and choose a screw jack with a suitable base and end fittings.
