Screw Jack

Tieshou manufactures industrial-grade heavy-duty mechanical screw jacks designed for high-precision lifting, positioning, and long-term static load holding. Engineered with precision-machined trapezoidal alloy steel screws and cast steel housings, our mechanical jacks deliver exceptional load capacity ranging from 3.2 tons to 100 tons without the risk of hydraulic pressure loss or fluid leakage.

Featuring an inherent 100% self-locking screw design, Tieshou screw jacks eliminate load drift under extended pressure, making them the safest choice for bridge construction, machinery leveling, building support, and cleanroom environments. Equipped with ratchet handles or bevel gear mechanisms, our mechanical lifting systems offer smooth manual operation, minimal maintenance, and full compliance with international safety standards.
