Screw jacks, also known as mechanical lifting jacks, convert rotary motion into linear lifting movement. Built with worm‑gear transmission and cast iron housing, these units deliver stable lifting performance, reliable self‑locking capability and long service life.
Our screw jack series covers multiple configurations: translating screw type, rotating screw type, top flange, clevis end, protective tube and anti‑rotation versions. They support manual handwheel operation or motor connection, can work individually or run in multi‑jack synchronous lifting systems.
Widely applied for equipment leveling, platform lifting, pressing, positioning and height adjustment across machinery, metallurgy, material handling, food processing and automation industries. Custom non‑standard modifications are available upon request.
