SWL Series Electric Worm Gear Jack for Electric Lifting Platforms

A worm gear jack is a mechanical drive that uses a worm wheel to convert rotational motion into linear motion. It is commonly used in a variety of industrial applications, such as lifting heavy objects or adjusting the height of equipment. Worm gear jacks are known for their high efficiency, strength, and durability.

The basic design of a worm gear jack consists of the worm gear, worm shaft, and lifting screw. The worm gear is a cylindrical gear with spiral threads engaged with the worm shaft. The worm shaft is the threaded rod that turns the worm gear. A lifting screw is a threaded rod that moves in a straight line when it is rotated by a worm gear.

SWL series worm gear jack is the basic part of lifting. Jack through worm gear drive screw to achieve lifting, pushing, turning, and other functions. The jack has two modes of movement: screw movement and nut movement. The input form of the jack has single shaft input, dual shaft input, flange input, flange plus shaft input, etc. Screw moving type and biaxial input type are the basic types of screw elevator, widely used.

Electric Worm Gear Screw Jack Applications:

Electric worm gear jacks are universal and are commonly used in industrial applications, manufacturing, and machining. They have a high load-bearing to effort-to-effort ratio and can be easily adjusted by automatic or manual screw rotation, providing operators with high reliability and synchronization capabilities. One advantage of our industrial jacks is that they can be used in series to mechanically lift and lower at the same speed. Some examples of applications using electric worm gear jacks 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

 

We are one of the best worm gear jack suppliers. We can offer wide worm gear jack stock. We have exported our products to clients worldwide and earned a good reputation because of our superior product quality and after-sales service. We welcome customers at home and abroad to contact us to negotiate business, exchange information, and cooperate with us!

Advantages of Worm Gear Jacks:

Worm gear jacks have several advantages over other types of lifting devices. Some of the main advantages of worm gear jacks include:

High load capacity: Worm gear jacks are designed to support heavy loads from a few hundred pounds to several tons.

Precise lifting: Worm gear jacks provide precise lifting and lowering control, making them ideal for applications where accuracy is critical.

Stability: Worm gear jacks provide steady lifting force and are unlikely to shift or slip even under heavy objects.

Durability: Worm gear jacks are designed to withstand heavy use and provide long-lasting performance.

Versatility: Worm gear jacks are available in a variety of sizes and configurations for a wide range of applications.
