Factory Direct Supply Hydraulic Bridge Jacking Equipment with 31.5MPa Working Pressure

The synchronous lifting jack represents advanced hydraulic technology for large-scale construction projects. This system integrates prestressed anchor technology with hydraulic jack mechanisms, utilizing steel strands and computer-controlled hydraulic pressure to achieve precise synchronous movement of heavy components.

Our PLC-controlled hydraulic system consists of five core components: hydraulic pump station, PLC computer control system, hydraulic circuits, displacement/pressure sensors, and industrial touchscreen interface. This integrated solution combines bridge engineering analysis with real-time monitoring technology to ensure lifting accuracy within ±0.5mm.

The working principle utilizes hydraulic pressure conversion, where motor-driven pumps generate high-pressure oil flow to actuate cylinder pistons. The wireless synchronous control system enables multiple jacks to operate in perfect coordination, with sensors transmitting real-time data to the central control unit for precise pressure adjustment.

Installation requires professional execution including pier positioning, hydraulic line routing with check valves, synchronous calibration through monitoring systems, and mandatory load testing at 50% design capacity before operation. Strict safety protocols must be followed, including weather protection and regular system maintenance.

Key features include:

• Computer-controlled synchronous operation
• Multiple capacity options from 50-1000 tons
• High-strength 18mm diameter steel strands
• 31.5MPa working pressure
• 500mm standard cylinder stroke
