Whole span segment launching gantry

The launching gantry is used to put the pre-fabricated segment
onto the pre-fabricated pier. It is a kind of crane with the main
function of lifting and transfer the segment to designated
position, but very different from the common crane. It’s more
strict than the common one and can be walked on. Launching
gantry can be divided into several kinds such as launching
gantry for highway, for common railway and for passengerdedicated
line, etc..

◆  Equiped with protection system which guarantee the absolute safety during working. It’s safe, easy
and practical.

◆  Easy installation and removal

◆ Safe & easy operation, easy fixing, and safty during walking

◆ Simple structure, clear big operational space and high efficient.

Q: What is the technical parameter of 30m/100t fixed guide beam of bridge erector?
Project WJQ50/180~200 WJQ40/150~160 WJQ30/100~120Maximum lifting weight (T) 180150100Adaptive bridge span (m) 35~50 30~40 20~30
Q: How much is a bridging machine
Bridge erection machine is mainly composed of steel structure, lifting, walking and other components, of which the proportion of steel structure
Q: Now the high-speed rail bridge frame span of the beam
The bridge erecting machine is a device for placing a prefabricated beam on a prefabricated pier
Q: When does the bridge machine not belong to the gantry crane?
But it is very different from the general sense of the crane. The requirements of the harsh conditions, and the existence of the beam on the line, or called the longitudinal shift. Bridge machine is divided into the erection of highway bridges, conventional railway bridge, passenger dedicated railway bridge, etc..
Q: What are the conventional lifting equipment? Bridge erecting machine is a kind of lifting equipment
Belongs to the non-standard crane, exactly belong to special equipment
Q: DJ180 bridge frame 40 m beam through the hole program.
Beam and girder operation,Beam operation and falling beamBeam plate transverse movement and falling beam falling beam laying rail welding seam
Q: The difference between double guide beam bridge machine and single beam bridge machine
Single beam bridge machine:The single girder bridge girder erecting machine adopts a single bearing beam, and the bridge erecting machine is composed of a single main beam, a supporting leg, a hanging beam trolley, a moving mechanism, a transverse moving mechanism and an electric control system. Main girder structure generally adopts box type structure of light weight, high stability of the beam, the guide beam can be moved up and down, back and forth, transverse, achieve a heavily beam beam falling in place, continuous erection line, line, curve and other different types of bridges.
