What's the general overview of walking type bridge girder launcher?
Walking type bridge girder launcher is a new type bridge construction crane developed by ZZHZ to meet the market demand, according to practical working condition, combining successful experience of ZZHZ and other companies, main features of the bridge girder launcher are as follows:
1. Unique honeycomb girder is firstly made by ZZHZ, featuring light self-weight, large load and high wind resistance;
2. New type and reasonable structure, the bridge girder launcher takes construction characteristics of modern bridges into account, use CAXA to design the model, so it has a more extensive adaptability;
3. The bridge girder launcher uses ANSYS finite element software to optimize the structure, making the bridge girder launcher has a light weight and high stiffness;
4. Middle support legs do not move on the bridge deck, it is unnecessary to lay rails, which reduces the pressure on the bridge deck as well as saves construction cost, thus the bridge girder launcher has a larger adaptability to the box type precast girder.
5. The bridge girder launcher uses support legs to move forward by itself, so it can better adapt to longitudinal and lateral slope in the actual working condition as well as make the bridge deck bear safer and more reasonable force;
6. Front support legs and middle support legs can be adjusted at random, core plate has adjustable angle, which make the bridge girder launcher better adapt to curved bridge and skew bridge; as constructing the skew bridge, the position of front support legs and middle support legs can be changed according to the angle of skew bridge, the machine can construct skew bridge with angle below 45°.
7. Adding transverse moving trolley as the lifting trolley, the complete machine can move transversely to the right place with boundary beam, safe, reliable, simple and fast;
8. Main girder and main connection structures of the complete machine adopt mature pin connection structure, stable, reliable as well as fast assembly and disassembly (striking a pin only needs several minutes).
