Honeycomb type beam launcher

Application range of honeycomb type beam launcher

It is mainly used for lifting concrete girders with full span lifting method in bridge construction projects.

Main features and advantages of honeycomb type beam launcher

(1)Honeycomb girder is patent product specially developed by ZZHZ, main features:

1. The air current could pass through the honeycomb holes, thus greatly reduce wind impact on the main girder, make it quite stable;

2. The honeycomb girder is welded plate by plate, so it has a relatively lower demand on welding, even if there is a mistake welding there (and we will not allow this mistake usually), the large welding surface will not lose stability, so it is quite stable and reliable

3. Its section is isosceles triangle which is the most stable structure in all shapes;

4. The honeycomb girder sections are connected with high strength bolts for convenient transportation and assembly. And the connecting parts are stiffened plates which will totally meet the demands of design loads. 


1. Middle support legs do not move on the bridge deck, it is unnecessary to lay longitudinal sliding rails, which reduces the pressure on the bridge deck as well as saves construction cost, thus the launching gantry has a larger adaptability to the box type precast girder.

2. The launching gantry 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;

3. Front support legs and middle support legs can be adjusted at random, core plate has adjustable angle, which make the launching gantry better adapt to construct 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°.


4. Transverse trolley is added to the lifting trolley, the whole machine traverses with boundary beam which resolve the problem of installation of boundary beam.
