Features
The 3D jacking equipment is an intelligent hydraulic system used in bridge construction. It utilizes modular control to precisely jack up bridge beams. Its core advantages include:
Core Technology
Using displacement sensor technology, it achieves three-dimensional synchronous control, enabling precise vertical lifting, longitudinal and horizontal jacking, and deflection correction. The modular design of the control system reduces workspace, resulting in high construction efficiency and low costs.
Core Functions
- Multi-unit Collaborative Control: The master control unit simultaneously controls multiple jacking units to ensure construction synchronization.
- Three-Dimensional Adjustment: Supports adjustment and positioning in X, Y, and Z directions, with a vertical travel of up to 150mm and a lateral travel of ±30mm.
- Intelligent Deflection Correction: Sensors monitor displacement in real time and dynamically adjust jacking parameters to maintain axis stability.
Typical Applications
It is primarily used in composite structure bridge construction, such as the integral jacking of steel beams across railway and highway bridges. It is suitable for safe assembly and precise positioning under complex working conditions.
