CASE STUDIES Ӏ ENERGY SECTOR
The fact that Dawes only
needed 11 truckloads to deliver the MLC300 was therefore a considerable plus. “With fewer truckloads, we needed less space for the staging area. That’s less cost for the customer, a smaller footprint, and quicker assembly,” said Hoops. “After delivering the loads to the laydown area, we trucked components to the build site one at a time – first bringing over the tracks, carbody, and counterweights and then the boom sections.” Dawes also brought a 100-ton Tadano GR-1000XL rough terrain crane to assist with assembly of the MLC300. According to Dawes other similar-sized crawler cranes would have needed up to three times as many loads, increasing delivery fees and set-up time, and would have had a larger footprint requiring additional ground matting. An all-terrain crane that
could handle the weight of the job at the prescribed radius would have needed at least double the capacity, it adds. Configured with 216 feet of main boom and 474,000lb (215 tonnes) of counterweight, the MLC300 offered the right combination of smaller footprint and large capacity to pick and set the two generators. The process took several hours for each generator, as on-site engineers supervised the securing of connections. After completing the lifts the remaining connections were finalised. Community leaders in Cannon
Falls, Minnesota, tout the project as the first in the nation to generate more electricity through renewable resources than will be needed by the local community. It enables the dam to produce clean power more efficiently and more reliably, with excess electricity
expected to be sold to help offset the project’s cost. The job was a joint effort of Dakota County, The Boldt Company, and Xcel Energy.
STORM-DAMAGED STACK On the other side of the Atlantic, in the UK, power related repair work required the expertise of leading crane hire specialist Ainscough. In December 2024 Storm
Mammoet’s
PTC-35 crane has replaced steam generators at Bruce Power, Ontario, Canada
Darragh swept through Northern Ireland causing widespread damage. Among the affected sites was a critical component of the region’s energy network, Ballylumford Power Station in Islandmagee. A section of one of its prominent chimney stacks partially collapsed during the storm. Full electricity generation was temporarily suspended. The chimney stack, standing 75 metres tall and weighing approximately 147 tonnes, was severely compromised and
