Synchronous Lifting Systems

It is commonly called a synchronous lifting system or synchronous jacking system. It can drive 4 or more hydraulic cylinders to jack up simultaneously. It’s often used for bridge jacking, lifting and lowering, steel structure installation, etc. The lifting accuracy can be up to 0.1mm to guarantee the synchronous operation. On the basis of the standard sync jacking system, there is also an extended product, such as a 3D jacking system. Steel strand jacking systems are another style of sync jacking systems. It uses a hydraulic cylinder to lift by alternately gripping and pulling the steel strands.

The Synchronization Accuracy and Load Balancing of EKXIA Synchronous Jacking Systems

Our synchronous lifting system can conduct real-time monitoring through displacement sensors and pressure sensors. Monitoring displacement and pressure changes at each lifting point in real time helps adjust oil flow. This ensures load balance during the process.

The pulse-width modulation (PWM) speed control system and the variable-frequency drive (VFD) system can achieve synchronization accuracy within ±0.1 millimeters.

The 3D synchronous system can achieve fine adjustments in the X, Y, and Z directions. It can ensure that the errors in the three directions are within ±0.5 millimeters.

The accuracy of our steel strand system and intelligent tensioning system is typically ±1 to ±5 millimeters.

Using our synchronous lifting system can prevent tilting or deformation during lifting.

Reliability and Stability of Synchronous Lifting System

The system is equipped with load-holding valves and self-locking functions. These two features can prevent sliding or falling in the event of a power failure or system malfunction.

The pulse-width modulation (PWM) and variable-frequency drive (VFD) control systems are very stable. They support continuous, uninterrupted operation and ensure the entire lifting process remains uninterrupted.

The 3D attitude monitoring system continuously monitors the status of the heavy object. It uses various sensors to gather information. Then, it automatically adjusts the force and speed of each jack. It can achieve a vibration-free, smooth force application throughout the lifting process.

The strand jack system supports an extremely long stroke and can continuously push for hundreds of meters. The intelligent tensioning system can achieve tensioning without impact.

Our synchronous lifting system monitors displacement and pressure changes in real time. It automatically adjusts the flow and pressure to keep the axis stable. It is very suitable for long-term operations in harsh environments.
