Screw Jack

Our screw jacks are heavy‑duty mechanical lifting devices designed for linear lifting, pushing and positioning tasks under various industrial working conditions. Adopting high‑strength worm‑gear drive and trapezoidal screw structure, these machine screw jacks deliver stable lifting performance, reliable self‑locking capability and high load‑bearing capacity.

They are widely applied in material lifting platforms, equipment height adjustment, valve opening‑closing mechanisms, metallurgical facilities, cement production lines and mining auxiliary machinery. We offer multiple tonnage grades, travel strokes and installation configurations. Custom service for special screw length, anti‑rotation structure and heavy‑duty protection cover is available.

As a professional Chinese manufacturer, we supply reliable screw jack solutions for industrial clients across Africa, South America and the Middle East. Share your load capacity, stroke and mounting requirements to get technical datasheet and competitive offer.
