Small Electric Screw Jack: A Comprehensive Guide

In this article, we will delve into the intricacies of small electric screw jack. We will explore its uses, working principle, differences with hydraulic jack, how to choose the right screw jack, and much more. But first, let’s understand what exactly a screw jack is.

What is a Screw Jack?

A screw jack is a mechanical device that converts rotational motion into linear motion. It consists of a screw mechanism, which is driven by an electric motor, hand crank, or hydraulic cylinder. The screw mechanism moves a load up or down, depending on the direction of the rotation of the screw.

What is a Screw Jack Used for?

There are several uses of screw jack, including:

  • Lifting heavy loads in industries such as construction, manufacturing, and transportation.
  • Positioning equipment or machinery in precise locations.
  • Adjusting the height of workbenches or tables in workshops.
  • Stabilizing structures such as scaffolding and bridges.
  • Supporting objects for inspection or maintenance.

What is the Working Principle of Screw Jack?

The working principle of screw jack can be explained in the following points:

  1. When the electric motor rotates the screw, the screw moves up or down, depending on its rotational direction.
  2. The screw is threaded, and it engages with the load, causing it to move.
  3. The load is supported by a nut that is attached to the screw or moves along the screw.
  4. The pitch of the screw determines the distance that the load moves for each revolution of the screw.

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

The main differences between a screw jack and a hydraulic jack are:

  • Screw jacks are slower in operation than hydraulic jacks.
  • Screw jacks have a lower lifting capacity than hydraulic jacks.
  • Screw jacks are more precise in positioning than hydraulic jacks.
  • Screw jacks are more compact and lightweight than hydraulic jacks.
  • Screw jacks are more affordable than hydraulic jacks.

How to Choose or Customize the Right Screw Jack?

When choosing or customizing a screw jack, it is important to consider the following parameters:

  • Lifting capacity: This refers to the maximum weight that the screw jack can lift. It depends on the diameter of the screw, pitch of the screw, and strength of the material.
  • Lift height: This refers to the maximum distance that the load can be lifted. It depends on the length of the screw and the number of threads.
  • Speed: This refers to the rate at which the screw jack can lift or lower the load. It depends on the pitch of the screw and the rotational speed of the motor.
  • Environmental conditions: This refers to the temperature, humidity, dust, and other factors that can affect the performance and lifespan of the screw jack. It is important to choose a screw jack that is suitable for the specific environment.
  • Mounting options: This refers to the different ways in which the screw jack can be mounted or integrated into the equipment or machinery. It is important to choose a mounting option that is compatible with the application.
