Hydraulic Lifting, Incremental Launching/Turning System developed by OVM company are made up of lifting jack (or incremental launching jack), hydraulic pump station, control system and bearing strands, it is the integrative modernized advanced equipment collecting machine, electricity, hydraulic pressure, sensor, computer and automatic control technology. According to the needs of different projects, adopting different dispositions to lifting jack (or Incremental Launching jack), hydraulic pump station, control system, it satisfied the demand of lifting force (launching force or turning force), synchronous precision and lifting speed(for launching or turning system) of whole ultra high altitude of different large-scale components for lifting in step. All dispositions can adopt the computer to control, and can adopt logic control too to realize automatic and hand movement industry system, and satisfy to promote essential adjustment movement industry of the lifting, incremental launching/turning course.

At present, with more and more special construction of structure, advantage of using hydraulic lifting technology (incremental launching technology or turning technology) constructed to go on more and more obvious.
* The hydraulic lifting the whole promotion, translation suitable for the oversize, overweight, superelevation component most heavy promotion weight. Now the largest lifting weight promotes up to 5800 tonses (large theater of Shanghai), and the highest lifting height promotes up to 350 meters (Shanghai Oriental Pearl TV Tower).
* The incremental launching technology is suitable for constructing in continuous concrete beam, especially while pier foundation lies in model U gorge and deep ditch unfavorable to scaffold erect, and while a bridge crosses over and runs the busy running channel or railway line.
*　The turning technology in hydraulic is suitable when the bridge crosses over and runs the busy running channel or the railway line too, such as level or vertical turning operation of the steel tube joining in YaJiSha Bridge in Guangzhou, the turning construction(turning weight reached 14,000 ton) in the overhead cable-stay bridge of the Shijingshan south railway station in the Beijing Fifth Ring Road, etc..

OVM hydraulic lifting, incremental launching and turning technology are continually applied to different various fields of projects, this technology has already become the favorable helper whose project constructed of every field.
