SWL Series Worm Gear Jack for Jump Form Construction Lifting

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 elevators, widely used.

SWL Series Worm Gear Jack Specification:

Structural form Type Ⅰ: axial movement of the screw rod Type Ⅱ: the screw rod rotates, and the nut moves axially
