Lifting systems are in great demand since more and more massive buildings or bridges tend to be shifted or lifted integrally. Hydraulic cylinders in traditional lifting systems are usually supplied by a common pump with an oil tank, which brings long distance hydraulic pipes and signal lines. This paper designs a new architecture of an intelligent lifting system, with

Synchronizing hydraulic cylinders is essential if you intend to lift a load using multiple lifting points. While this is possible to achieve with an operator and pump at each lift point, it isn’t always the easiest or the safest way to go about it. Using a synchronized lifting pump provides more accuracy and involves less risk.
