Four 12 metre, track-mounted mobile hydraulic work platforms achieved what larger machines couldn’t on Brisbane’s Gateway Bridge duplication project.
A Queensland Government initiative being delivered by Queensland Motorways, with design and construction by the Leighton bigroup Joint Venture (LAJV), the construction of the new Gateway Bridge is an integral component of the $1.88 billion Gateway Upgrade Project.
The Kennards Hire track-mounted mobile hydraulic work platforms were lowered by crane through specifically sized recess in the deck of the mainspan for works inside the twin concrete box cells.
Crews used them for finishing works over the entire length of the cast in-situ balanced cantilever structure of the new Gateway Bridge.
“This type of machine was used as they could fit through the deck recess and could handle the bottom slab 22 per cent grade,” said LAJV’s Project Director, Hugh Boyd.
“We have been satisfied with the performance of the mobile hydraulic work platforms and Kennards have worked with LAJV to achieve the desired outcomes.”
The Kennards’ track-mounted mobile hydraulic work platforms have excellent traction, particularly on uneven ground, and can negotiate grades of up to 60 degrees.
They are self-propelled, compact, highly manoeuvrable and can pass through a 750mm wide opening. Working height is 12.2 metres.
