This machine is designed to place 900 ton
concrete box beams. It can also reduce dimension by itself without
disassembly in order to pass through tunnels with the help of the
tyre trolley, which will save time and money for the erection of
1.1 Working condition
·For erecting the concrete box beam in areas that bridges
connect with tunnels, the machine can go through the tunnel and
erect the beam 7m away from the entrance of exit or the
·Going through on the continuous beam, combination beam or
·Different height of the concrete box beam in one
· Surmountable slope 2 %
· Min. radius of the bridge 1400m.
Wind speed: 72km/h with load, 144km/h without load
1.2 Main technical characteristics
·Change the machine from the high position into lower position
through a hydraulic system. Then the launching gantry can go into
or out of tunnels in a lower position with the help of tyre
·This machine can place segments with a distance of 7m from the
tunnel entrance or exit.
·Transported without the help of supporting frame.
·Fixed lifting point creates a good stability
Changing jobsite with the help of tyre trolley.
