product description

HZQD900 bridge girder launcher is the high-speed railway bridge girder launcher which is applied to the project construction in the mountain and plain areas. It can travel in the tunnel without dismantling. The girder transportation adopts the independent girder carrier and suitable for the construction within 30km distance.

Product advantages

1,The bridge girder launcher and girder carrier work independently, the girder transportation speed is high and save the fuel.
2, The "O" type support leg is adopted in the rear part of the bridge girder launcher, the structure strength is high.
3, During the bridge girder launcher travels forward, the main girder moves along the middle support leg.
