500 Ton Hydraulic Bridge Lifting Jack for Construction and Maintenance Projects

The SFST-500 hydraulic bridge lifting jack is engineered for demanding construction and maintenance applications. With a robust 500 ton capacity and 25MPa working pressure, this professional equipment delivers reliable performance for bridge repair, structural lifting, and bearing replacement projects.

Key features include a built-in safety pressure holding device with pressure relief valve to prevent overload situations. The synchronous control system ensures stable operation during critical lifting operations. The jack's durable construction includes a 145mm cylinder diameter and meets international safety standards.

For installation and operation, always verify all components are in proper working condition before use. Maintain proper hydraulic oil levels with filtered N33# hydraulic oil. When multiple jacks are required, use diverter valves to ensure balanced load distribution and synchronized lifting.

Typical applications include:

• Bridge maintenance and rehabilitation
• Structural lifting and lowering operations
• Bearing replacement projects
• Heavy equipment installation
• Load transfer operations

The SFST-500 represents professional grade lifting equipment designed for construction professionals and infrastructure maintenance teams requiring reliable, high-capacity hydraulic solutions.
