    Screw Jacks

    The Screw Jacks are the types of jacks, which are functioned by turning the lead screws. In this form these are commonly utilized to lift moderate heavy weights like vehicles. More usually these are employed as the adjustable supports for heavy loads, such as large vehicles or the foundations of houses. These can not only assist heavy loads but not lift it. The advantage of these Screw Jacks that they are self-locking that means when the rotational power on the screw is separated, it will remain inactive where it was left and will not turn backwards, irrespective of how much load it is bearing.

    Key Points :

    • Inherently safer in comparison with hydraulic jacks.
    • Have large orbit of sliding contact between the screw threads.
    • Have high friction, not continuously used for ceaseless transmission of high power.
    • Utilized in periodic positioning applications, utilized extensively in aviation, raise and reduce the horizontal stabilizers.
