DF900D Nose-girder Positioning Beam Launcherf (DF900D BL for short)develop by us is one of our NDF’s advanced equipments specialized for erecting Class 900t Railway Box-girder Bridge.
With high manufacturing quality, it was developed and improved on the base of our DF900 simple-span type Lauching Girder and desiged with many excellent features by absorbing advantadges of same purpose equipments at home and abroad.
Applicable Scope
DF900D Launching Girder is used to erecting Railway Precast Concrete Box-girder Bridge with span up to 32meters and weight up to 900tons. For bridge type, it often used to erect Double-track monolithic box- girder Bridge, and can meet different span-beams’ erection (like 32m,24m and 20m) in one project.
Besides the normal operation, it perfectly meets the needs to erect first-span and last-span beams and can be operated and exchange flexibly between many different construction conditions. And transported by our Elevating Transporter(ET), it can be moved from one place to another and pass through tunnels.

- Q: why Singapore import machinery and equipment, mineral fuels, chemicals?
- I lived in Singapore for a month, so my answer for you is a reflection of that experience and what I learned there (briefly) from talking with some co-workers. Singapore is a wonderful little country that is in between several economic powers - Malaysia, Indonesia (the 5th largest country in the world), China, Japan and the Koreas; (but you know all that already) - It is a very favorably positioned and accessible seaport. These trading policies were undoubtedly part of the policies of P.M. Lee Kuan Yew. It is a very active, willing and cooperative trade partner and in return gets great deals on imported goods from sea trade in return for favorable trading terms. I personally would love to live there, but the heat and humidity are too much for me to make that decision. HTH
