STQS200-300 Hydraulic push jack with anti-eccentric load is mainly used for bridge bearing replacement, bridge jacking, structural correction, foundation adjustment, steel structure installation, and heavy equipment positioning. Its anti-eccentricity structure can adapt to uneven or eccentrically loaded scenarios, reducing damage to the piston rod and cylinder from lateral forces and improving the safety and stability of the jacking and pushing process.

High-Force Hydraulic Performance
With a rated capacity of 200 tons and a working pressure of 63 MPa, this anti-eccentric hydraulic jack delivers powerful and stable performance for demanding construction and industrial applications. It features an effective piston area of 31,400 mm², a 300 mm stroke, and a closed height of 650 mm, making it suitable for long-stroke jacking, structural lifting, and precise load positioning.

Compact but Heavy-Duty Structure
Although designed for high-load applications, the jack has a total weight of only 230 kg, making it easier to transport, install, and handle on site. Its compact yet strong design provides reliable operation in limited working spaces and complex job site conditions.

Universal Anti-Eccentric Load Design
This hydraulic push jack is equipped with a top-mounted universal ball joint measuring Ø200 mm in diameter and 190 mm in thickness. The self-aligning structure allows the jack to adapt automatically to uneven, inclined, or skewed load surfaces, helping reduce side-load stress and protect the piston rod and cylinder from damage during heavy-duty pushing or lifting operations.

Robust Flanged Base Mounting
The square flange base, sized 370 × 370 × 40 mm, provides firm and stable mounting for fixed-position applications. The base can also be customized according to project requirements, making the jack ideal for bridge bearing replacement, structural jacking, foundation adjustment, and heavy equipment positioning.
