What is applicable range of honeycomb girder launching gantry?
Honeycomb girder launching gantry is widely used for building bridges with features as following:
overhead launching gantry
HZQY launching gantry for carrying and erecting girders
HZQY launching gantry for carrying and erecting girders made by ZZHZ was transferred to another worksite.
HZQY launching gantry for carrying and erecting pre-cast girders made by ZZHZ had transferred to another worksite smoothly a few days ago after distinguishing itself in Yungui Railway.
What preparations should you make before assembling the launching gantry?
In order to assemble launching gantry smoothly and successfully, we shall carefully make a preparation in advance.
Main technical paramters of HZQ59/80 segments assembly launching gantry
HZQ59/80 segments assembly launching gantry is used to construct Punggol Bridge in Singapore, whose construct way is: lift segment up firstly, then level it, coat epoxy resion, then lift another one up and coat it, finally tension them together.
How about honeycomb girder launching gantry?
Manufactured by ZZHZ, the main beam of our honeycomb girder launching gantry is welded by triangle beams. The complete honeycomb girder is in low gravity and very safe. Honeycomb-shape hole can decrease the influence from wind. The weight of honeycomb girder launching gantry is between box girder and truss, which has strong rigidity and small deflection.

What are safety rules to disassemble the launching gantry?
After the launching gantry finishes installing precast girders, it needs to work in another worksite. With heavy weight, large volume and long distance, it is necessary to disassemble the launching gantry for a convenient transportation. Below are some rules that shall be followed:
assembly of main girder
How to test steel plates for launching gantry?
Launching gantry main girders usually use Q235 and Q345 steel plates, which bear main loads. So it is vital to purchase high quality steel plates.

How to do anti-corrosion coating of launching gantry?
Anti-corrosion coating is quite important for normal operation and good appearance of launching gantry.
What are differences between honeycomb girders and box girder, truss girder
Launching Gantry produced by ZZHZ accesses to national patent with isosceles triangle honeycomb type main girder, it features light self-weight, high stiffness, low deflection and high wind resistance.
