SWL Lead Screw Lift

The SWL series worm gear screw jacks feature numerous functions including lifting, lowering, and, with the aid of accessories; propulsion; tilting; and various height adjustments. They are listed in the JB/T8809-1998 standard. They are widely used in various industries such as machinery, metallurgy, construction, water conservancy, chemical industry, medical, and sports. The SWL worm gear screw jack is a basic lifting component with many advantages, including compact structure, small size, light weight, no noise, safety and convenience, flexible use, high reliability, wide range of power sources, multiple supporting functions, and long service life. It can be used individually or in combination, and can accurately control and adjust the lifting or propulsion height according to a specific program. It can be directly driven by an electric motor or other power source, or manually. The load capacity ranges from 2.5t to 120t, with a maximum input speed of 1500 rpm and a maximum lifting speed of 2.7m/min. To improve the efficiency and load capacity of the SWL series worm gear screw jacks, special and advanced processes have been developed to enhance the overall performance of the jacks and meet the requirements of a wide range of customers.
SWL comes in different structural and assembly types, and the lifting height can be customized according to user requirements.
