Synchronous Jacking System

 

RIVERLAKE PLC synchronous lifting system is based on PLC control technology, which controls lifting and positioning through sensor feedback. The control process does not need to consider the central distribution of heavy objects. It is suitable for lifting large and heavy-duty bridges, especially suitable for supporting RSM/RCS/CLP ultra-thin jacks to replace bridge supports. By changing the flow of each cylinder to adjust the jack’s lifting displacement, the system maintains a good position control. By eliminating human interference, synchronous lifting maintains the integrity of the mechanism, improves production efficiency, and enhances the safety of lifting actions. The synchronous lifting system based on PLC control reduces the risk of bending, twisting, and tilting caused by uneven weight distribution and load transfer between different lifting points. The core electrical control system uses the German Siemens PLC programmable controller, which combines high-performance displacement sensors and pressure sensor detection systems to achieve dual control of pressure control and displacement control, thereby ensuring the precise control of the jack and the safety control of the lifting process


  • A double plunger pump power system is adopted to achieve rapid leveling and heavy load leveling.
  • The control precision can reach 0.5mm for lifting and lowering operation
  • The product can be controlled flexibly according to different working conditions, cylinder capacity and quantity, and jacking accuracy
  • Each control point is relatively independent and can be adjusted independently without interference
  • The system monitors from 4 to 48 lifting points.
  • It has a data storage and recording function to facilitate the generation of reports.
  • Optional variable frequency motor driver(VFDM) and PLC device to ensure accurate synchronization and flow control.
  • Simple and intuitive human-computer interaction interface, easy to set parameters and operation.
  • The system is able to optimize the speed of load-lifting/lowering regardless of the number and size of cylinders maintaining the error within the set limit.
  • The information displayed for each cylinder are: relative and absolute position,pressure,force,direction (upward / downward),information relating to errors
  • 2 modes are available: automatic or manual.
  • Load and stroke alarm display for maximum safety during operations.
  • Display of the maximum relative error between various cylinders.
  • Displacement sensors and cables to be ordered separately
  • Optional load cells up to 15,000KN can be ordered. Our system can work with load cells to display real-time load data which often required by pile load testing operation
