4. Three-speed motor and mono-speed ratio decelerator are applied in the lifting struction, which enables heavy load low speed and light load high speed.
5. Planet gear decelerator is applied in the circumgyrating structure, together with moment-limiting hydraulic coupler, which can relize high load capacity, steady starting and reliable operation.
. This Machine is used for erecting concrete box girders for high speed (250km,350km) passenger railway lines.
2. This machine is suitable for equal span girders or different span girders which can be 20m, 24m and 32m .
