What is a Screw Jack Used For?

Screw jacks are simple mechanical devices used to lift heavy loads vertically or to move them horizontally. These jacks are commonly used in various industrial applications, such as heavy-duty machinery, construction equipment, and material handling systems.

Heavy-Duty Machinery

Screw jacks are commonly used in heavy-duty machinery to lift and move heavy loads, such as in mining, construction, and manufacturing industries.

Construction Equipment

Construction equipment, such as cranes and excavators, often use screw jacks to lift and move heavy materials, like steel beams and concrete blocks.

Material Handling Systems

Material handling systems, like conveyor belts and assembly lines, use screw jacks to lift and move materials from one location to another.

What is the Working Principle of Screw Jack?

Screw jacks work on the principle of the simple machine called a screw. When a force is applied to the handle of the screw jack, the screw turns, and the load placed on the jack is lifted or moved. The load is lifted by the linear motion of the screw, which rotates in the threads of a nut.

Translation Motion

Screw jacks convert rotary motion into linear motion, which is used to lift or move loads in a straight line.

Self-Locking Feature

Screw jacks have a self-locking feature that helps to prevent the load from falling or lowering when the handle is released.


Screw jacks are highly efficient because they use the principle of mechanical advantage, which allows them to lift or move heavy loads with minimal effort.

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

Screw jacks and hydraulic jacks are both used to lift heavy loads. However, they differ in terms of their operating principle, load capacity, and maintenance requirements.

Operating Principle

Screw jacks use a mechanical screw to lift or move loads, while hydraulic jacks use a hydraulic cylinder to lift or move loads.

Load Capacity

Screw jacks are designed to lift or move heavy loads, but their load capacity is limited compared to hydraulic jacks. Hydraulic jacks can lift or move heavier loads at a faster rate than screw jacks.

Maintenance Requirements

Screw jacks require less maintenance than hydraulic jacks because they do not use hydraulic fluid or have complex hydraulic systems. Screw jacks have simple mechanical components that are easy to maintain and repair.

How to Choose or Customize a Suitable Screw Jack?

Choosing or customizing a suitable screw jack depends on various factors, including load capacity, travel distance, speed, environmental conditions, and mounting requirements.

Load Capacity

The load capacity of the screw jack should be selected based on the maximum weight of the load to be lifted or moved.

Travel Distance

The travel distance of the screw jack should be selected based on the vertical or horizontal distance that the load needs to be lifted or moved.


The speed of the screw jack should be selected based on the required lifting or moving speed of the load.

Environmental Conditions

The screw jack should be selected based on the environmental conditions, such as temperature, humidity, and dust or dirt exposure.

Mounting Requirements

The screw jack should be selected based on the mounting requirements, such as the type of mounting base, the mounting direction, and the mounting location.
