APRIL / 2014
The Underslung Launching Gauntry LG is a high efficiency
equipment specially designed to install precast concete segments in
the box section
deck and typically spans in the order of 30 to 35m.
When the span activities are repetitive the achieved performance
using these Launching Gantries allow in a week to install all the
segments
corresponding to 2 spans and in some cases even 2,5 spans.
Each span built using the precast segments has a lenght
corresponding to the distance in between the center to center of
columns.

Main components:A simple solution!
The Underslung Launching Gantry is a simple solution to support
the precast concrete segments, being made by two almost
symmetrical
halves.Each half includes a main girder and two noses, supported
at three
supporting brackets pairs connected to the columns. On the top
of the two main girders travels a gantry crane that perform the
segments assembling. On the main girder inner web outer surface
there are several support beams where the precast segments are
supported
awaiting to be adjusted and prestressed.

Some of the inovations introduced by STRUKTURAS:
Independent main structure, connected only by the gantry crane,
allowing to do transversal adjustments from a single track to
double or even triple.
Implement hinge connections on the Underslung Launching Gantry
making it possible to be used at decks with horizontal radius as
small as 75m.
The hydraulic underslung support system where segments are
supported allows correction of any misaligments resulting from
lifting phase.
The STRUKTURAS Launching Gantries exceeds conventional design
limitations in modern
bridge construction! Both Underslung and Overhead
Launching Gantry solutions consists of two main structures
combined with advanced lifting
devices, creating an exceptionally flexible system for both
methods of construction
from span to span or cantilevering.
