When the walking type bridge girder launcher works, it finishes bridge construction by transverse movement and longitudinal movement. Below are some tips to briefly introduce the transverse movement of bridge girder launcher:

a. As an important front part support of the bridge girder launcher, front support leg uses transverse movement gear box and transverse sliding rail to make the whole machine move transversely

b. As an important rear part support, middle support leg uses transverse movement gear box and transverse sliding rail to make the whole machine move transversely

c. Transverse moving mechanism at upper part of the lifting trolley can make the trolley move transversely along transverse sliding beam and rail

d. Install boundary beam

Lifting trolley moves transversely with girder, the distance between lifting steel wire rope and bottom chord of main girder is about 5cm.

The complete machine moves laterally to drop the concrete girder at the pre-calculated position, so that boundary beam installation can be finished once, the bridge girder launcher does not move out the bridge abutment, safe, reliable, simple and convenient.
