Jet SJ 20T 20 Ton Screw Jack: An in-depth Guide

Screw jacks are versatile mechanical systems that convert rotational motion into linear motion, making them useful in various industrial applications. In this article, we will discuss the Jet SJ 20T 20 Ton Screw Jack in detail as well as explain how screw jacks work and how they differ from hydraulic jacks. We will also explain what screw jacks are used for, how to choose the right one, and give a brief overview of HZPT, a leading manufacturer of screw jacks.

What is a Screw Jack Used For?

Screw jacks are used for various applications, including lifting, lowering, pushing, or pulling heavy loads. They are commonly used in industries such as automotive, aerospace, manufacturing, construction, and entertainment for different purposes. Here are some common uses for screw jacks:

1. Lifting Heavy Machinery

Screw jacks are used to lift heavy machinery and equipment in various industries for maintenance or repair purposes. They can lift loads of up to 200 tons effectively and efficiently.

2. Supporting Structures

Screw jacks can be used to support structures or bridges. They provide a stable foundation by adjusting the height or tilting the structure to the desired angle.

3. Adjusting Positioning

Screw jacks can be used to adjust the positioning of objects, such as adjusting the height of a welding workstation.

4. Stabilizing Objects

Screw jacks can be used to stabilize objects that are prone to tipping or leaning, such as large machinery that needs to be adjusted or leveled.

5. Heavy-Duty Push and Pull

Screw jacks can be used to push or pull heavy loads, such as moving equipment or materials. They are especially useful when dealing with heavy machinery that requires precision movement.

What is the Working Principle of Screw Jack?

Screw jacks operate according to the basic principle of a worm gear. There are two main components of a screw jack: a worm gear and a worm. The worm gear is rotated by a motor, which causes the worm to rotate, thereby moving the lift shaft up or down.

The ratio of the worm gear determines the efficiency of the screw jack. The greater the ratio, the greater the load that can be lifted with less force. The screw jack also features a safety mechanism to prevent overloading, which could result in damage or injury.

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

Screw jacks and hydraulic jacks both serve the same purpose, which is to lift heavy loads. However, there are some differences between the two types of jacks:

1. Power Source

Screw jacks are manually operated or powered by an electric motor, while hydraulic jacks are powered by hydraulic fluid or air pressure.

2. Load Capacity

Screw jacks have a lower load capacity than hydraulic jacks. Screw jacks can lift up to 200 tons, while hydraulic jacks can lift up to 1,000 tons.

3. Maintenance

Hydraulic jacks require more maintenance than screw jacks due to the fluid or air pressure systems.

How to Choose or Customize the Right Screw Jack?

Choosing the right screw jack depends on the specific requirements of the application. Here are some factors to consider when choosing or customizing a screw jack:

1. Load Capacity

The load capacity of the screw jack should match the weight of the load being lifted or moved.

2. Travel Distance

The travel distance of the screw jack should match the required range of motion for the application.

3. Screw Pitch

The screw pitch should be selected based on the desired lifting speed and load capacity.

4. Drive Type

The drive type, such as hand-crank, motorized, or manual, should be selected based on the application requirements.

5. Environment

The environment in which the screw jack will be used should be considered when choosing or customizing a screw jack. Factors such as temperature, humidity, and corrosion resistance should be taken into account.
