IT’S ALL SYSTEMS GO

IT’S ALL SYSTEMS GO WITH SKF SYSTEM 24 LUBRICATION SOLUTION When one of SKF’s longstanding customers experienced numerous breakdowns and production losses due to lubrication issues on their cyclone extractor fans, SKF, in close collaboration with its Authorised Distributor, West Cape Bearings and Transmission (Pty) Ltd, stepped in with the perfect automatic lubricator and grease solution. The cyclone extractor fans are used to extract sawdust from the work areas in a wooden door and window manufacturing plant and are safety critical units as the facility cannot operate if there is excessive air contamination. In addition to a number of products supplied by SKF to the customer, including bearings, seals, and lubricators, West Cape Bearings and Transmission carried out condition monitoring which was analysed by SKF. “It was the data collected through the condition monitoring that alerted the customer to serious lubrication issues,” explains Eddie Martens, Product Manager: MaPro at SKF. The manufacturer approached the SKF Authorised Distributor, West Cape Bearings and Transmission, for assistance. After conducting a mini lubrication audit, SKF found that many of the cyclone fan units were being over greased whilst some units were not being greased at all. This inconsistent greasing was causing, on average, two catastrophic failures on the cyclone fans every month. SKF recommended a trial run on its System 24 lubricator and LGHP 2 grease fitted on one cyclone fan. According to Martens, positive results were evident within the first month of testing which impressed the customer so highly that they decided to convert all of their cyclone fans to automatic System 24 lubricators. Martens adds that the original test fan has now been running for over twelve months without interruption or failure. The fact that these advanced automatic System 24 lubricators require minimal maintenance means extended service intervals on the fans, maximising uptime. The elimination of manual lubrication further boosts uptime and, importantly, enhances the safety of personnel who are now freed up to perform other tasks. Cost savings due to less grease being used contribute to lowest total cost of ownership for the customer. “SKF is committed to equipping customers with knowledge and the knowledge that has been transferred to our customer’s maintenance team has both improved uptime on the units and created greater awareness of areas that need improvement,” notes Martens. This has resulted in SKF providing training courses to the maintenance teams as well as guidance on the establishment of the improved lubrication store. According to Martens, the customer is also in the process of implementing a lubrication planner to further enhance the knowledge they have received. Furthermore, they are purchasing special tools to improve maintenance. “As a global bearings and lubrication system specialist, we strive to provide customers with cutting-edge solutions that not only solve their problems but tranform the way in which they operate,” says Martens. “This project has prompted a collaborative partnership between our customer, our Authorised Distributor, West Cape Bearings and Transmission, and SKF. We are committed to providing state-of-the-art solutions to our customers so that we remain their preferred bearings and lubrication partners along their business growth journeys.” About SKF SKF’s mission is to be the undisputed leader in the bearing business. SKF offers solutions around the rotating shaft, including bearings, seals, lubrication, condition monitoring and maintenance services. SKF is represented in more than 130 countries and has around 17,000 distributor locations worldwide. Annual sales in 2018 were SEK 85 713 million and the number of employees was 44,428. www.skf.com 4

FRONT COVER STORY SKYRIDERS ELIOS SKYEYE DRONE POWERS UP EMERGENCY TUBE-LEAK INSPECTION The project was a showcase for the rapid deployability and flexibility of the drone. When a major coal-fired power station in Limpopo experienced a tube leak in a boiler that subsequently resulted in a burst pipe, Skyriders Access Specialists (Pty) Ltd. was called upon to deploy its Elios SkyEye drone technology for an emergency inspection. This is the first time that the confined-space inspection technology has been deployed in such an application, Marketing Manger Mike Zinn reports. “The client required an urgent visual inspection, in addition to determining the possible collateral damage associated with the area.” Zinn explains that the drone was controlled just outside of the boiler itself. “We were not necessarily flying it blind due to the presence of its cameras, but it did have to cover a considerable distance.” The drone was not only able to take highdefinition photographs of the internal area of the boiler in question, but was able to pinpoint the exact location of the suspected tube leak. “We also piloted the drone around the adjacent walls and surrounding area in order to verify whether or not there were any additional issues,” Zinn explains. While the Elios SkyEye drone has been used for inspection work on two previous occasions at the same power station, this was the first time it was called upon in an emergency situation. Skyriders dispatched a two-person team that was quickly on-site, and able to get the drone into the boiler as soon as possible. The project was a showcase for the rapid deployability and flexibility of the drone. Traditionally, scaffolding or other rather time-consuming means of access would have to be first erected prior to inspections being carried out. Skyriders dispatched a two-person team that was quickly on-site, and able to get the drone into the boiler as soon as possible. The Elios SkyEye drone has dramatically improved the health and safety of on-site crews in such projects, allowing specialised teams to enter only once the situation has been thoroughly analysed and verified. If need be, rope access is then used for teams to carry out additional inspection services such as ultrasonic wall thickness testing or other non-destructive testing methods. Imported from Flyability of Switzerland, the hi-tech Elios SkyEye drone includes a full HD camera, a thermal camera, and an onboard LED lighting system with remotely-adjustable intensity. Hence an array of onboard tools is available for any lighting conditions. The drone can be brought into usually inaccessible places up to many hundred metres beyond the line of sight due to the fact that it is equipped with a wireless communications system with a live video feedback. “The main issue with this project is that it was an incredibly difficult area to access. Here the collision-tolerance feature of the drone meant it was able to access the affected area quickly and reliably. The fully-qualified and trained pilot means that the inspection work itself is carried out rapidly and professionally, producing real-time results for the client,” Zinn concludes. About Skyriders Skyriders (Pty) Ltd, established in 1998, is a leader in the South African rope access industry, providing cost- and time-saving solutions to clients in the power generation and petrochemical industries who require rope access aided inspection, NDT and maintenance work to be done in difficult to reach, high-up locations.
