A versatile gantry lifting system from Enerpac (A Division of Actuant Corp)
was deployed by a contractor to precisely position electrical power generating equipment at the new Owen Springs Power Station near Alice Springs in Central Australia.
Applying their expertise for head contractor MAN Diesel & Turbo Australia, Tutt Bryant Heavy Lift & Shift used the SBL1100 modular hydraulic jacking system to install diesel/gas generators and alternator sets each weighing hundreds of tonnes.
The new $A126 million Owen Springs Power Station is near Alice Springs, about 1500km inland from the nearest port or major city.
Designed as a major infrastructure development seeking world’s best practice in fuel efficiency and reduced carbon emissions, the three 10.9 MW diesel gas generators and their alternators were transported overland from the Port of Darwin by Tutt Bryant Heavy Lift & Shift using multiple prime movers with a 16-axle, 3-file hydraulic platform trailer for each of the generators, and a 4x8 low loader and 2x8 dolly for each of the alternators.
Once on site, the generators and alternators needed to be unloaded and placed onto their respective foundations. Enerpac’s SBL1100 modular hydraulic jacking system was deployed along with self-propelled trailers that were able to jack up and down.
The utilisation of such specialised transportation and alternative lifting equipment allowed each of the generators and alternators to be unloaded and relocated all in a single operation, increasing the efficiency of the task.
Tutt Bryant Heavy Lift & Shift’s Western Region Operations Manager for Specialised Transport, Mr Justin Congdon explained that the installation was a delicate process due to the tight confined space and the need to precisely align the machinery. During execution, Tutt Bryant Heavy Lift & Shift was able to implement innovative solutions such as building a ramp up on to the alternator foundations and enabling side shift capability mode on the modular hydraulic jacking system, enabling the alternators to be manoeuvred into their respective bays sideways and placed within a 2-3mm tolerance.
According to Mr Congdon, the SBL1100 was a key technology involved in this exercise, allowing them to efficiently transport the unit over long distance to the project site while the unit’s quick ‘plug and play’ setup typically required only half a day.
He adds that the SBL1100, once set up has a lifting height of nearly 13 metres and a lifting capacity of up to 1,100 tonnes. The self-contained hydraulic system has a fail-safe design with three-stage hydraulic cylinders mounted upside down in an octagonal shaped boom design while powered side shifters ensure maximum placement accuracy.
Hydraulic gantries are a safe and efficient way to lift and position heavy loads in applications where traditional cranes may not be practical. Ideal for use in industries such as mining and resources plant, oil and gas structures, energy and infrastructure installation and maintenance and ports and shipping, Enerpac’s SBL1100 modular hydraulic jacking systems provide a controlled and precise method of lifting and installation even in projects constrained by permanent overhead structures.
Completing their task on schedule, Tutt Bryant Heavy Lift & Shift ensured the prompt continuation of the installation and construction works of the power plant. In providing efficient methodologies, thorough pre-planning and careful execution, Tutt Bryant Heavy Lift & Shift not only achieved the client’s objectives, but also further enhanced their reputation as a leading heavy lift and transportation provider in Australia.
