Integrated hydraulic system relocates
Concert Hall
Enerpac Integrated System Technology has been widely recognized as the highest-level sophisticated technology in the high-pressure hydraulic industry: 59 cylinders moved the Shanghai Concert Hall
The decision to relocate the 74-year old Shanghai Concert Hall building was made mainly because of noise from neighbouring areas With the city's busiest expressway nearby the aged building has been plagued by noise and exhaust gas

With its south and west walls close to a populated residential complex, daily chaos often burst into the music hall.
Although building a new Concert Hall would have been less expensive, the Shanghai City choose to move the entire building to retain the distinctive architecture and acoustics.
Built during their early 1900s construction boom, the former Nanking Theatre was Shanghai's first venue for foreign film and was one of the few buildings of its era designed by a Chinese architect.

Known for its excellent acoustics, the theatre has been used as a venue for symphony orchestras since 1959.
After its relocation and renovation, the old concert hall will again welcome orchestras.
The Shanghai Concert Hall relocating project involved three main stages: 1st: Lifting the entire concert hall 1.7 meters from its original foundations 2nd: Moving the entire building 66.4 meters southeastwards to its present location 3rd: Lifting the building another 1.68 meters and lowering and positioning it down on a new base.
Before the relocating project, engineers had spent seven months strengthening the construction and collecting data on the inside force system.
During the entire lifting and moving process, a variety of data-collection tools and instruments collected every millimetre of change.
Due to the mixed foundation design and the lack of an integrated frame, the 5,800 tons building was extremely difficult to lift and move.
For that reason the music hall was put onto a 1,800-ton armoured concrete tray.
This tray would help the building move along the tracks.
In addition, both the exterior and interior of the building were strapped with steel structures.
Now the physical pre-requisites were there to apply the Enerpac high-accuracy integrated hydraulic system technology.
The Enerpac Integrated System Technology has been widely recognized as the highest-level sophisticated technology in the high-pressure hydraulic industry.
The entire system for the concert hall relocation project included 59 cylinders with a capacity of 200 tons per cylinder and 4 large hydraulic pump stations with the ability to both weigh and lift.
The central PLC-control system controlled and monitored all movements.
The entire Shanghai Concert Hall was lifted in only 6 days to the prescribed height of 1.7 meters.
The journey southeastwards, down ten tailor-made concrete tracks, went smoothly and took only 12 days.
As the tracks could only withstand the weight of the concert hall for about ten days, ten large hydraulic cylinders were installed underneath the building to take the stain.
The first day, the building moved less than 40 centimetres and during the first five days, the total distance moved was only 3.5 meters.
The following days however the building reached a speed of 2 meters per hour and the longest distance covered in a single day was 16.5 meters.
The integrated hydraulic system with high-tech PLC system was used to control all processes and movements, ensuring both safety and accuracy.
At the new site, the building was raised another 1.68 meters, so that a new foundation could be moulded to dovetail with the building.
Now that the relocating project has been completed, technical staff are making improvements to the concert hall, to make this old hall a venue for the 21st Century.
The stage will be enlarged and a new basement will be built.
