MINING HOISTS
Cross section of the innovative Teufelberger- Redaelli 7Mine rope
This very often includes an onsite hoist inspection.
Due to the technology involved, 7Mine and 8Mine have a higher initial cost than triangular strand ropes for the same application, so their advantage is in TCO given the much higher performance. That is why having the data is so important in making the case to customers – Teufelberger-Redaelli now has detailed data from installations not only in South Africa and the USA but also Mexico, Canada, Poland, Zambia and Zimbabwe.“ The more data we have, the more we can show customers what our products are capable of. We also have developed our own calculation tools which help us based on the hoist parameters combined with the current rope service life, maintenance procedures and legal requirements, to propose a certain rope construction from which we expect a certain performance. This fact-based approach has proven to be very reliable. It allows us to indicate an optimum rope solution almost immediately and this is very powerful when also combined with our continuous improvement program and our close interaction with customers.”
After a rope is removed from service, the company sits down with the customer to reflect on what has been learned together and what can be improved in terms of rope construction plus it works with them on maintenance and handling procedures to get the best out of it and to help them to lift their hoisting systems to the next level. Schoisswohl:“ And it is important to mention that this is all without any fancy technology. By that I mean there’ s nothing in the rope like load bearing synthetic fibres which cannot currently be inspected from the outside without opening up the rope. All our high performance mining ropes can be inspected with MRT systems and visually just like any triangular strand rope.”
Summarising – 7Mine and 8Mine allow customers to get the extra performance but with the rope matching the rope weight and diameter and the breaking forces without the customer that previously used triangular strand ropes having to change anything.“ There are some other parallel lay round strand ropes in the market, but we are unique I think in the customer not having to make special adjustments to use them like having to install new attachments to allow for a different rope diameter.”
Schoisswohl also highlighted the strength of its Gardone val Trompia and Trieste, Italy manufacturing locations.“ We acquired Redaelli in 2017 and it has been a huge asset in terms of its capabilities – as an example, it manufactured the heaviest wire rope ever produced – an offshore Flexpack rope of almost 500 t in its facility in Trieste. So we have no weight limitations in our supply of mining ropes – this shows you the size of the closing machines that we have at our disposal. Long term, we are looking at making Gardone a global competence centre for mining ropes – the set up there is ideal for a project-based business like mining, plus we already have our wire drawing department there which allows us to produce customised wires for our mining ropes. Today Gardone produces the 7Mine with the 8Mine produced at our Austria factory in the Traisen Valley.”
