What is a screw jack used for?

A screw jack is a device used to lift heavy loads to a desired height. It is often used in various applications, such as raising or lowering work tables, adjusting conveyor belts, and leveling heavy machines or equipment.

Construction of screw jack

A screw jack is usually made up of a lifting screw, worm gear, worm gear housing, bearings, and motor. The lifting screw is the main part of the screw jack that carries the load, while the worm gear is used to rotate the screw. The worm gear housing and bearings support the worm gear and the screw, respectively. The motor is used to drive the screw jack.

Types of screw jack

There are two main types of screw jacks: mechanical and electrical. Mechanical screw jacks are operated manually, while electrical screw jacks are powered by an electric motor.

Advantages of screw jack

  • High load capacity
  • Precise positioning
  • Easy to install and maintain
  • Can be used in various applications
  • Durable and long-lasting

What is the working principle of screw jack?

The working principle of a screw jack is based on the concept of the inclined plane. When the worm gear is rotated, the lifting screw moves up or down depending on the direction of the rotation. The pitch of the screw determines the distance the load is lifted per revolution of the screw.

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

A screw jack is powered by a motor that rotates the lifting screw, while a hydraulic jack is powered by pressurized fluid that lifts the load. Hydraulic jacks are usually more expensive and require more maintenance, but they can lift heavier loads than screw jacks and operate more quickly.

How to choose or customize the right screw jack?

When selecting a screw jack, it is important to consider factors such as load capacity, lifting height, speed, and duty cycle. The load capacity should be greater than the weight of the load to be lifted. The lifting height should be sufficient to meet the application requirements. The speed of lifting should be appropriate for the application, and the duty cycle should be considered for applications that require extended use.
