Motorised Screw Jack

A motorised screw jack, also known as an electric screw jack, is a mechanical device that uses a motor to turn a screw, which in turn lifts or lowers a load. This type of jack is commonly used in the industrial sector for heavy lifting and positioning applications.

What is a screw jack used for?

  • Transportation: Screw jacks are used to lift and lower the platforms on transportation equipment, such as trailers and cargo trucks to ensure smooth loading and unloading of goods.
  • Automotive: Screw jacks are used in automotive repair shops to lift cars and other vehicles to allow mechanics easy access to the undercarriage.
  • Machinery: Screw jacks are used in manufacturing plants to lift heavy machinery and equipment for maintenance and repair.
  • Aerospace: Screw jacks are used in aerospace applications to adjust the positions of engine components and control surfaces.
  • Construction: Screw jacks are used in construction projects to lift heavy loads, such as steel beams and precast concrete panels.

What is the working principle of screw jack?

The working principle of a screw jack is based on the concept of a simple machine known as the inclined plane. The screw jack consists of a screw, a nut and a motor, which drives the screw to generate linear motion. As the motor rotates the screw, the nut moves up or down along the length of the screw, depending on the direction of rotation. This linear motion is then used to lift or lower a load, depending on the application.

  • Efficiency: Screw jacks are less efficient than hydraulic jacks because they require more energy to lift the same load.
  • Speed: Screw jacks are slower than hydraulic jacks due to the slower speed of the motor.
  • Load capacity: Screw jacks have a lower load capacity than hydraulic jacks due to the limitations of the screw and nut design.
  • Size: Screw jacks are typically larger and heavier than hydraulic jacks due to the motor and screw design.
  • Maintenance: Screw jacks are easier to maintain than hydraulic jacks because they have fewer moving parts.

How to choose or customize a suitable screw jack?

  • Load capacity: The load capacity of the screw jack should be chosen based on the weight of the load it will be lifting.
  • Stroke length: The stroke length of the screw jack should be chosen based on the distance the load needs to be lifted or lowered.
  • Screw pitch: The screw pitch of the screw jack should be chosen based on the speed at which the load needs to be lifted or lowered.
  • Operating speed: The operating speed of the screw jack should be chosen based on the application’s requirements.
  • Environment: The screw jack should be chosen based on the environmental conditions, such as temperature, humidity, and corrosive agents.
