The walking intelligent jacking hydraulic system is used for the synchronous jacking of steel box.

girdersDue to the heavy jacking weight, large span and complex structural stress of the long-span steel box girder, the traditional clip-on rail jacking is difficult to meet the requirements. The walking intelligent jacking hydraulic system integrates jacking, jacking, and correction adjustment, and adopts computer centralized control to achieve highly automated and self-balancing jacking.





The steel strand synchronous lifting hydraulic equipment is used for the synchronous lifting of steel box girders of Chongqing Osmanthus Bridge

The main span of the main bridge of Chongqing Osmanthus Bridge is a 550-meter twin-tower steel box girder suspension bridge, and the main tower adopts an arc-shaped portal reinforced concrete structure composed of 5 curves. The project connects the Zhengwan high-speed railway station, Wushan County and the airport, which will play a good role in promoting the development of Wushan County and the development of surrounding districts and counties.



The steel strand synchronous lifting hydraulic equipment is used in the steel truss hoisting project of Guojiatuo Yangtze River Bridge

As an important part of the "six vertical lines" of Chongqing's "six horizontal and seven vertical" expressway network, the upper level of the Guojiatuo Yangtze River Bridge is designed as a two-way eight-lane passage, and the lower level is reserved for the river crossing channel of rail transit line 8, which is expected to be completed in October 2022, and the first steel beam has been successfully erected.



The steel structure covered bridge is lifted and installed synchronously as a whole

The 2,600-ton "behemoth" steel structure covered bridge was simultaneously lifted by 78.57 meters, with a height of 94.75 meters and a span of 81 meters, accurately lifted between the two towers, reflecting the surrounding high-rise buildings and becoming a beautiful landscape.



The expansion jacking project of the Huai'an section of the Beijing-Shanghai

Expressway uses the Cairn frequency conversion control synchronous jacking hydraulic system to synchronously jack 16 hydraulic jacks. The project has a total length of 107 kilometers, and the whole line adopts the standard reconstruction and expansion of two-way eight-lane expressways, with a design speed of 120 km/h, 96 bridges and 8 interchanges on the whole line.



The project is a concrete cast-in-place box girder structure, with a total weight of about 3000T, and adopts PLC synchronous jacking hydraulic system to meet the technical requirements of multi-point synchronous overall construction. The project includes a construction scheme integrating Z-direction jacking and X/Y direction correction, which can realize the relevant process requirements of vertical jacking, longitudinal slope adjustment, lateral displacement and horizontal rotation of the bridge.



Oujiang Beikou Bridge steel box girder synchronous weighing project

Using Jiangsu KIET high-precision intelligent weighing hydraulic system, the large-tonnage hydraulic jack is used to realize the overall jacking and lowering of the steel box girder for bridge construction, and the weight data of the load cell attached to the jack is read to accurately obtain the weight of the structural parts. By setting the coordinate system of each point and combining it with the weight of the corresponding point, the center of gravity coordinates of the structural part is automatically calculated.

Cold box module synchronous weighing project

The cold box module is synchronous weighing, using 5 sets of PLC multi-point synchronous weighing hydraulic system, and supporting 20 sets of 300T weighing hydraulic jacks synchronous jacking and weighing.



1800 tons offshore ship internal pipe gallery module weighing project

With the increasing demand for oil and gas resources for human and economic development, the development of offshore oil and gas has become inevitable. Offshore equipment is necessary equipment for the development of offshore oil and gas resources, but due to its large volume and weight, it is necessary to use intelligent weighing hydraulic systems.





Lifting appliance loading test

The spreader loading test hydraulic equipment uses hydraulic characteristics to realize the control of cylinder displacement and force through the automatic control of displacement closed loop and force closed loop. When testing different spreaders, as long as the corresponding model code is entered into the computer, the servo system will automatically control the action of the cylinder to simulate the acceleration (braking force acceleration) state when the object falls, and collect the changes in the loading force to generate a map.



Synchronous transfer of transformers

The main transformer of the Three Gorges Hydropower Station has the structural characteristics of large tonnage and large volume, which is difficult to construct during installation and maintenance and transportation. The transformer intelligent transfer hydraulic system sets synchronous jacking, autonomous walking, synchronous movement and other functions, with the characteristics of small size, strong load capacity and high control accuracy, and is an intelligent transfer hydraulic equipment integrating mechanical, electrical and hydraulic.
