Design Of Synchronous Hydraulic System

With the progress of science and technique, the building of railway traffic has also been achieved rapid development. So it is required that the related technology of laying railway track must develop firstly. During the laying works of the railway track, there are higher demands on the building of railway bridge and the work is more difficult than other works. This will promote the development of equipments of related technology. The main studying object is the transverse dolly of the box girder. The primary role of the dolly is that carrying the prefabricated box girder to the designated workplace for the next prefabricated box girder. The major research content of the paper analyses and designs the push hydraulic system and synchronous movement control system of the dolly, it contraposes the requirement of synchronous movement of the twin dollies.The paper firstly brings forward the source of research issue and the...
