SWL05 Spiral Bevel Gear Lifter

SWLScrew Jack

SWLSeries worm gear screw lifters are a fundamental lifting component, compliant withJB/T8809—1998(Original)JB/ZQ4391—86Standard. Load capacity2.5—120TCompact structure, small size, light weight, wide power sources, low noise, easy installation, flexible operation, multiple functions, various matching forms, high reliability, and long service life. Can accurately control and adjust the lifting or propulsion height according to a certain program, can be directly driven by an electric motor or other power source, or operated manually. Input speed1500r/minEnhance speed2.7m/minVarious structural styles and assembly methods are available, with the lifting height customizable to meet customer requirements. The device features an automatic locking mechanism.

Lead Screw Lifters, also known as Spiral Drive Mechanisms. It is primarily used to convert rotational motion into linear motion or vice versa. There are those mainly for transmitting energy, such as spiral presses and jacks; others for transmitting motion, like the feed screws of machine tool tables; and still others for adjusting the relative positions of parts, such as spiral drive mechanisms. Screw lifters come in sliding friction and rolling friction types.
