SWL Series Electric Worm Gear Screw Jack for Electric Lifting Platforms

SWL series screw jack is composed of a worm gear reducer and a lifting screw, and its deceleration component is a worm drive, which uses the worm to drive the worm gear to achieve deceleration. The center of the worm gear is an internal thread structure, which is equivalent to the nut of the lifting screw and matches the lifting screw. The drive modes of the screw jack include manual drive, motor drive, and geared motor integrated drive. Motor drives include AC motors, stepper motors, servo motors, etc., which are connected with screw jacks through flanges. Electric worm gear screw jacks are widely used in various electric lifting platforms. In addition, the screw can be installed upwards or downwards according to different application requirements.

Advantages of Electric Worm Gear Screw Jack

Advantages of Electric Worm Gear Screw Jack Electric Worm Gear Screw Jack Advantages
Higher Performance

· Accurate and smooth delivery of force.

· Increased range of actuation as the stroke position is easily and quickly varied.

· Electro-mechanical solutions are more resistant to temperature variations.

· Complete control of the entire motion profile using standard control methods.

· Repeatable and accurate positioning.

Reduced Costs

· The motorized worm gear screw jack is generally cheaper when compared to a hydraulic system when the required ancillary hydraulic equipment is included.

· Machinery requires less maintenance as no hydraulic oil to maintain, and no leaks to repair.

· Less manual intervention on machinery to set up processes as electro-mechanical solutions can be controlled over the complete motion profile.

· Reduced downtime caused by hazardous fluid leaks.

· Electro-mechanical solutions only use power when moving the load. In comparison, hydraulic systems generally have to maintain pressure levels to either maintain position when holding a load or to ensure that the system can respond when required.

Increased Safety

· In the event of power loss, screw jacks can be self-locking.

· No high-pressure oil leaks.

Electric Worm Gear Screw Jack Applications:

Electric worm gear screw jacks are versatile and commonly found in industrial applications, manufacturing, and machining. They have a high loadbearing-to-effort ratio and the ability to easily adjust heights by turning a screw, either automatically or manually, providing high reliability and synchronization capabilities to the operator. An advantage of our industrial screw jacks is that they can be used in tandem to mechanically lift and lower at the same speed. Some examples of applications where electric worm gear screw jacks are used include:

  • Satellite dish antenna movement
  • Roll lifts
  • Conveyor lifts and diverters
  • Saw blade tension
  • Robotics manipulators
  • Workplace table adjustments and platforms
  • Welding positioners
  • Door openers
  • Air dampeners
