Wisen technology was successfully deployed by Parramatta Connect to ensure a major milestone was met on the Parramatta Light Rail project.
As part of a major operation to lift in to place the second longest steel arch bridge span in New South Wales, the 64-metre long, 15-metre-high steel arch bridge was moved using four Self Propelled Modular Transporters (SPMTs).
Sarens provided the SPMTs, crane structure and personnel to ensure the heavy lift went off without a hitch.
The crane structure on top of the SPMTs had to remain in tolerance for verticality and the SPMT vehicles had to remain within set distance tolerances front to back.
Wisen Tri-axial tilt nodes were mounted at key locations on the structure to watch for changes in the longitudinal and transverse directions of the bridge. Meanwhile, Wisen distance meters kept a watchful eye on the distance between SPMTs.
Data was viewed in real time through the Wisen cloud portal. Alarms were ready to send in real time should tolerances be exceeded as well as an onscreen ‘traffic light’ indicator thus allowing any corrections to be made to the SPMT’s hydraulics.
During a busy Saturday night shift, the construction crew, survey and engineering teams moved the bridge in to its final position.
Richard Ingham National Product Manager for Monitoring Solutions at C.R. Kennedy commented ‘it was great to see our products and solutions applied in a unique way to solve a dynamic measurement challenge.’
