1）Working environment and condition
·Launching concrete box beam with same length span or different
length span, with ballast or without ballast.
·Different height of the concrete box beam in one bridge
· Surmountable slope 3 %
· Min. radius of the bridge ***0m
·Wind speed: *2km/h with load, **4km/h without
load.
2）Main technical
characteristics ·
When the launching gantry finishes placing concrete beams and the
under bridge tries to launch forward，the whole machine is driven by
the chain system of the small trolley under the launching leg. That
can ensure a stable movement, and will never create additional
force movement to the gantry.
· When the location of machine assembly is close to the launching
jobsite, the launching gantry can move to the abutment itself and
can also place itself on the pier to be ready to erect concrete box
beams.
· After finishing erecting the concrete beam of one bridge,
the launching gantry can move forward by itself on the deck or go
through the existing deck or steel bridge.
· With the help of special transporting frame, the launching
gantry can be moved on the railway basement or deck by tyre
trolley.
·When it is necessary to go through certain areas with height
limits or some narrow areas such as tunnels, the machine can be
partly disassembled to reduce its section dimension. Then with the
help of transporting the frame, the launching gantry can pass the
limited area.
