Overview
SWL series worm screw lifts have many functions such as lifting, lowering, pushing with auxiliary parts, turning and various height position adjustments, which have been listed in the JB/T8809-1998 standard. They are widely used in various industries such as machinery, metallurgy, construction, water conservancy, chemical industry, medical treatment, culture and sports.
SWL worm screw lift is a basic lifting component with many advantages such as compact structure, small size, light weight, no noise, safe and convenient, flexible use, high reliability, wide range of power sources, multiple supporting functions, long service life, etc. It can be used alone or in combination, and can accurately control and adjust the lifting or propulsion height according to a certain procedure. It can be driven directly by an electric motor or other power, or manually. The load capacity is 2.5t-120t, the maximum input speed is 1500 rpm, and the maximum lifting speed is 2.7m/min.
In order to improve the efficiency and carrying capacity of SWL series worm gear screw jacks, special and advanced processes have been developed to improve the overall performance of the jacks to meet the requirements of our customers.
SWL has different structural types and assembly types, and the lifting height can be customized according to user requirements.
