The Olympic Dam mine, which is the fourth largest copper deposit and the largest known single deposit of uranium in the world, relies on overhead cranes for li[ing different reagents as part of their producঞon process, as well as performing vital maintenance tasks. The Olympic Dam project is set to benefit from BHP's investment of more than AUD$600 million over FY2018 on a range of works. According to BHP's Asset President, Olympic Dam, Jacqui McGill, this is the most significant investment BHP has ever made in South Australia and it will help build the foundaঞons for long term, safe, stable and sustainable growth at Olympic Dam. "The investment will ensure the operaঞon is more modern, reliable and can support processing of addiঞonal tonnes in coming financial years," she said. Mr Sco Montgomerie, BHP Supervisor, Floats Maintenance Execuঞon, Olympic Dam, Minerals Australia, said that the old cranes were breaking down frequently, causing downঞme and producঞon losses. Konecranes safety inspecঞons are designed to assess the remaining life of cranes, and determine whether it is safer and more cost-effecঞve to replace a crane, repair it, or perform a modernisaঞon. New Konecranes overhead cranes at BHP's Olympic Dam mine in South Australia BHP Billiton's Olympic Dam mine boosts global output with the help of Konecranes "Konecranes provided us with some great replacement opঞons, and were flexible in their approach as well as having the technical experঞse to solve any unique challenges that arose," he said. Konecranes is providing BHP Billiton with five new cranes, ranging from 1t to 3.5t li[ing capacity. They were a mixture of CLX chain hoists and CXT wire rope hoists, designed to opঞmise efficiency, safety and reliability at Olympic Dam. The latest Konecranes CLX chain hoists, of the type specified by BHP for Olympic dam, incorporate a longer lifeঞme, with up to 1600 hours on most models with a full load, and a durable aluminium construcঞon. Durability of the li[ chain was a key element in the CLX's design for outstanding service. The patented chain sprocket dramaঞcally improves the durability of the chain. The oil lubricaঞon-based transmission reduces the operaঞng temperature, enabling increased power. Furthermore, the new transmission is maintenance-free and quiet to operate. The CLX's transmission increases the speed raঞo between low and fast speeds. The new 6:1 speed raঞo enables a safe and accurate installaঞon speed and an extremely fast movement speed. The wider speed range makes the CLX chain hoist 25 per cent faster than its predecessor, which helps speed up the work cycle and improves work efficiency. Safety funcঞons have been integrated into the standard characterisঞcs of the hoist. For example, the brake and the clutch have been installed on the same axle, which prevents the load from dropping even if the clutch breaks down. CXT wire rope hoist cranes, of the type also being installed at Olympic Dam, are designed to be industry benchmarks of safety and ergonomics, with easy and effecঞve load handling and opঞmum dimensions for space saving soluঞons. Konecranes CXT wire rope hoist cranes uঞlise the latest technology for improved load accuracy, versaঞlity and ease of use – making them the industry leader in medium-heavy indoor cranes.
