Introduction
The intelligent continuous jacking system consists of a continuous jack, a continuous jacking pump station, a control system, etc. It is a high-tech engineering application equipment integrating electromechanical and hydraulics. The pump station of this system adopts variable frequency speed control flow technology to achieve stepless speed regulation; the system has the characteristics of 1-12 multi-point parallel precise synchronization and balanced traction, which can make the entire jacking (rotation) force process stable and without impact vibration. It is mainly used in engineering construction such as bridge rotation, overall jacking of bridge beams, and horizontal continuous jacking (traction) of large components.
Product Performance
- The main features of the automatic continuous traction system lie in its continuity and synchronization.
- The system’s main control system and pump station control box are based on a PLC programmable controller, enabling multiple functions to be achieved by adding or modifying programs.
- Continuity means it can continuously and uniformly push a large object horizontally over distances of tens or even hundreds of meters or rotate it horizontally to any angle.
- Synchronicity means it can synchronize the operation of multiple jacks.
This not only overcomes the adverse effects of repeated starting and stopping during multi-point jacking, but also significantly accelerates construction.
