Installation of Deck Units in Brisbane An example of good practice Universal Cranes was contracted to install prestressed deck units at a private residential build in Balmoral, Brisbane. The site was complex with the requirement to setup on a split street sloping road surrounded by power lines, residential housing, vehicular and foot traffic, and a large radius of 44m. With extensive lift studies carried out and safe execution of the lift, the project provides a great example of good practice in outrigger design. The lift studies determined a GMK4100L was the most suitable crane for the job, with its 60m boom and smaller outrigger base being the primary deciding factors for this complex site layout and operating environment. In the lead up to the job, Brisbane experienced terrible weather with rain and thunderstorms forecast for lift day. Due to the effect inclement weather would have on an already difficult setup, the job was rescheduled for the following week. However, the GMK4100L wasn’t available for this new date so the setup was redesigned to suit a GMK5130, which still provided a good solution for the site demands. 14
