Product Detail
The PLC Portable Multi‑point Synchronous Hydraulic Lifting System is engineered for precise, coordinated lifting across multiple support points in demanding civil and industrial scenarios. Built around a PLC core, it combines hydraulic drive with closed‑loop control of both pressure and displacement to maintain synchronization throughout the entire lift. This architecture enables stable, repeatable movement while protecting structures and equipment from uneven loads.
The system is available in low‑pressure and high‑pressure portable configurations to match different site conditions. The low‑pressure version excels in routine bridge maintenance tasks such as replacing highway bridge rubber bearings, lifting overpasses, and rectifying or positioning equipment. The high‑pressure version extends capability for heavier bridge works and complex multi‑point bridge jacking operations, integrating proven international technologies with the company’s long‑standing hydraulic expertise.
Operators benefit from an intuitive human–machine interface that supports both tactile button operation and touchscreen control. Pulse‑Width‑Modulation delivers fine metering of flow for smooth starts, controlled speed, and accurate stopping. A standard four‑point synchronization package handles common lifting schemes, while the system’s network communication allows point expansion for larger or asymmetrical structures. Control models, control points, and extended points can be configured to suit project‑specific lifting sequences and safety interlocks.
Field applications include synchronous lifting of highway and inland river bridges, overpass lifting, bearing replacement, equipment lifting and rectification, and the translation of historic buildings where structural integrity and uniform movement are critical. By uniting portable hardware, closed‑loop automation, and scalable multi‑point control, this system offers contractors a dependable solution that shortens setup time, enhances safety, and raises the quality of bridge and infrastructure maintenance. It effectively fills a market gap for a compact yet sophisticated synchronous lifting solution tailored to highway and bridge requirements.
