Screw jacks is a mechanical device which includes screw mechanism to raise or lower the load. Screw jacks are widely used for industrial machinery for varied applications such as tipping, lifting, lowering or moving. Screw jacks play an important role for linear actuation requirements. The selection of screw jacks depends on various factors such as the type of load, desired speed for lifting, temperature conditions etc. The screw jacks are operated with pneumatic, electrical, hydraulic, and manual inputs. Under extreme chemical or mechanical conditions, the screw jacks are manufactured with special materials and in order sustain the extreme environmental conditions. Some of the key parts of screw jacks are trapezoidal lifting screw, worm gear, worm screw and gear housing. The lifting screw controls the linear motion speed which is dependent upon the thread size and worm gear rotation ratio. The screw jacks is an important device for industries where is used for various applications such as food processing machinery, theatrical stage setups, industrial processes, construction, mechanical lifting applications etc. More than one screw jacks can also be connected together for applications which require simultaneous movements. The global screw jack market is primarily driven by its excellent operable features such as easy to mount and extend till a wide area with the aid of other accessories.
