The Hazelwood Power Station is a now decommissioned brown coal-fuelled thermal power station located in the Latrobe Valley of Victoria, Australia. Due to the age of the power station, concrete delamination had began to take effect externally on each of the six chimneys. The client required an access system that could be used around the entire perimeter of each stack and at varying elevations, which would allow workers to remove the delaminated concrete before applying new concrete through the shotcreting process.
HOW SKY CLIMBER HELPED:
Using Sky Climber swing-stages with an articulating cradle allowed workers the extended reach to cover a larger portion of the chimneys circumference in a single drop. This custom solution gave workers the ability t0 repair the entire chimney with less drops, reducing the time required to reposition each of the main wire ropes when accessing each of the chimney. Alpha 800 hoists were used for this project due to their superior durability and proficiency in operating over long distances. Each of the four Alpha 800 hoists worked flawlessly despite being in contact with a large amount of dust and debris produced by concrete repair works. This allowed for less downtime associated with malfunctioning equipment, over the course of the project, and gave workers the confidence that the swing stage would be able to quickly descend to ground level in the event of high winds or rain.
