Introduction

A screw jack, also known as a worm gear jack, is a mechanical device that is widely used in various industries for lifting, lowering, or moving heavy loads. Duff Norton is a leading manufacturer of screw jacks, offering a wide range of high-quality products that are suitable for different applications. In this article, we will provide a comprehensive guide to Duff Norton screw jacks, covering their uses, working principle, differences from hydraulic jacks, and how to choose or customize the right jack for your needs.

What is a Screw Jack Used For?

Screw jacks are commonly used for the following applications:

1. Lifting and Lowering Heavy Loads

One of the most common uses of screw jacks is for lifting and lowering heavy loads in various industrial settings. This includes the lifting of heavy machinery and equipment, as well as for other applications such as bridge stabilization, stage and theater rigging, and industrial automation.

2. Moving Heavy Loads Horizontally

Screw jacks can also be used for moving heavy loads horizontally, such as in the movement of large industrial equipment or the positioning of workpieces in manufacturing processes.

3. Adjusting the Height of Workstations

Screw jacks can be used to adjust the height of workstations or other equipment to provide a comfortable working position for employees. This is useful in applications such as assembly lines, packaging lines, and other industrial processes.

4. Controlling Tension in Cables and Chains

Screw jacks can also be used to control tension in cables and chains, such as in conveyor belts or other material handling systems.

5. Providing Linear Motion

Screw jacks can also be used to provide linear motion in various applications, such as in robotic systems, solar tracking systems, and other automated machinery.

What is the Working Principle of Screw Jack?

The working principle of a screw jack is based on the conversion of rotary motion into linear motion. The screw jack consists of a worm gear that rotates the screw, which moves a load nut along the screw. As the load nut moves along the screw, it raises or lowers the load.

The key advantage of screw jacks over hydraulic jacks is that they can hold loads in position without the need for external support. Screw jacks are also more precise and easier to control than hydraulic jacks, making them ideal for a wide range of industrial applications.

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

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

1. Operation

Screw jacks are operated manually using a hand crank or an electric motor, while hydraulic jacks are operated using hydraulic fluid.

2. Precision

Screw jacks are more precise than hydraulic jacks, making them ideal for applications that require precise positioning or movement.

3. Load Capacity

Screw jacks have a lower load capacity than hydraulic jacks, but they can still handle heavy loads in most industrial applications.

How to Choose or Customize the Right Screw Jack?

When choosing or customizing a screw jack, the following factors should be considered:

1. Load Capacity

The load capacity of the screw jack should be sufficient to handle the weight of the load being lifted or moved.

2. Operating Speed

The operating speed of the screw jack should be suitable for the application. High-speed screw jacks may be required for applications that require rapid movement, while slow-speed screw jacks may be needed for precise positioning.

3. Duty Cycle

The duty cycle of the screw jack should be considered, as it will determine the frequency of use and the amount of time the jack can be operated without overheating.

4. Environmental Conditions

The environmental conditions in which the screw jack will be used should be considered, such as temperature, humidity, and exposure to corrosive substances.

5. Mounting Options

The mounting options for the screw jack should be considered to ensure that it can be easily and securely mounted in the desired location.
