The screw jack achieves functions such as lifting, lowering, pushing, and flipping through worm gear transmission. It is a fundamental lifting component widely used in various industries including machinery, metallurgy, water conservancy, chemicals, healthcare, culture, and sanitation. It features a compact structure, small size, lightweight, easy installation, flexible use, high reliability, excellent stability, and long service life. It can be directly driven by an electric motor or other power sources, and can also be operated manually. This series of worm gear screw jacks are self-locking, with a load capacity ranging from 2.5t to 120t, an input speed of 1500r/min, and a lifting speed of 2.7m/min. They come in different structural types and assembly methods, with an operating environment temperature between -20°C and 100°C. The lifting height is manufactured according to user requirements.

Features of the screw jack:

1. Smooth transmission, no noise;

2. Low impact vibration;

3. Suitable for low-speed, high, and low-frequency applications;

4. Mainly used for small to medium loads;

5. Load holding: The trapezoidal screw has an automatic locking function, allowing it to hold the load even without a braking device;

6. Safety setting: Equipped with a limit switch to prevent exceeding its stroke and damaging the screw and nut.
