Anita Garibaldi Bridge

BRAZIL (LG50/100S) 2013-2014

Location
Laguna, Brazil
Year
2013-2014
Project
Type: Bridge, total length 2815m (9235 ft.)
Typical Span: 50 m (164 ft.)
Deck width: 24 m (78 ft.)
Typical Cross Section: Box
Equipment features
Model: LG50/100S
Construction Type: Precast segments
Type: Overhead
OPS System: Integrated
Performance: 4-day cycles Overhead crane for the transport and lifting of precast segments It also allows the construction, in balanced cantilever method, of bridges with spans up to 100 m
Challenges
Precast segments should be admitted by the already built bridge or from the ground/ water.
Solutions
Autonomy: locomotion of the whole and transport and assembly of supports carried out via the overhead crane
Optimised operation: the OPS system enables the control of deformations while positioning the precast segments
Results
Construction period: 75 weeks
Spans carried out by LG 50/ 100: 49 spans of 50 metres
Higher productivity than expected, achieving cycles of 3.5 days
Higher operating safety of the machine, due to the reduction of lauching operations
High construction quality and deformation control
