Product details
Overview SWL series worm gearscrew liftAlso known as QWL elevators and spiral elevators, they are widely used in industries such as machinery, metallurgy, construction, and water conservancy equipment. They have many functions such as lifting, lowering, pushing with auxiliary components, flipping, and adjusting various heights and positions SWL worm gearscrew liftIt is a basic lifting component with many advantages such as compact structure, small volume, light weight, wide power source, no noise, easy installation, flexible use, multiple functions, multiple supporting forms, high reliability, and long service life. It can be used individually or in combination, and can accurately control and adjust the height of lifting or propulsion according to a certain program. It can be directly driven by an electric motor or other power, or manually operated. It has different structural and assembly forms, and the lifting height can be customized according to user requirements. The device can be self-locking
