SWL Series Double Input Shafts Worm Gear Jack for Construction Jump Form

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.

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.
