Product details
Detailed introduction of JWM screw lift
JWM screw liftIt is one of the products operated by Pawlejack in Dezhou City, widely used in industries such as machinery, metallurgy, construction, and water conservancy equipment. It has many functions such as lifting, lowering, pushing with auxiliary parts, flipping, and adjusting various height positions. JWM worm gear screw lift 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 relevant programs. 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.
JWM screw liftcharacteristic::
1 The JWM type (trapezoidal screw type) is suitable for low-speed and low-frequency applications, and its main components are precision trapezoidal screw pairs and high-precision worm gear pairs.2. Economical price, compact structure, easy operation, and convenient maintenance.
3. Low speed and low frequency: mainly used in places with high loads, low speeds, and no need for frequent work.
4. Maintain load: The trapezoidal screw has an automatic locking function, which can maintain load even without a braking device.
Technical parameters:
1. Input power: 0.36-21.4KW
2. Pitch range: 6-25mm
3. Load range: 2.5T-120T
4. Speed increase: 150mm/min-1800mm/min
5. Structural form: Click on direct connection, single input force axis, double input force axis
