Our company designs and manufactures 1500t and 2000t ultra-high-pressure electric hydraulic jacks and control systems. The jacks are equipped with pressure maintaining devices, and the hydraulic pump stations are equipped with unloading valves, three-position four-way manual reversing valves, relief valves, and one-way throttling. Valve and other control valve groups can ensure the working stability of the hydraulic system.
The fine-tuning and leveling of the steel box girder on the main pier was successfully completed, and the construction was coordinated with the padlock fixation of the box girder stay cables. The maximum length of the main pier steel beam is 826 meters, and the lifting tonnage is 2,000 tons.
Mainly through the distributed installation of twenty-four 2000t ultra-high pressure jacks and 1500t ultra-high pressure jacks, the sensor collected data is fed back to the hydraulic control system to synchronously control the jacking to achieve the fine-tuning effect of the main pier steel box girder jacking, in conjunction with the box girder stay cables. Padlock secures construction. Among them, the length of the single steel beam of the largest main pier is 826 meters, and the lifting tonnage is 2,000 tons.
