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