Good foundations at BSC Orange cement relationship with Hanson quarry

The BSC branch in Orange, New South Wales, has been servicing mines and quarries in the central-west region since 1965. “Other bearing companies have come and gone, but we remain – it’s testament to the strong foundations of BSC, which is currently celebrating 100 years of business, and is Australia’s longest established distributor of bearings and power transmission,” says Branch Manager of BSC Orange, Phil McGarity. “Becoming a part of Motion Asia Pacific has been a huge milestone for us, but our purpose remains the same: to keep the local businesses in motion.”

That of course extends to customers such as the Hanson aggregate quarry in Molong, about 30 minutes northwest of Orange.

“We have been solutions providers to the Hanson quarry since I’ve been branch manager here – so at least 13 years,” says Phil. “Back in 2011 they were having ongoing issues with their conveyor, with repeated bearing and shaft failures. We had our engineers go out to site to assess the situation and create a custom bearing solution. It significantly reduced their issues and improved their productivity.”

After diagnosing the problem – which was componentry failure due to dust and rock getting into the housings and bearings – the BSC team recommended the Timken® Spherical Roller Bearing Solid-Block Housed Units.

“We offered them this bearing solution and provided an in-house training session at our Orange BSC branch,” expands Phil. “They have now installed this product on every conveyor over the last 10 years.”

Sales representative Kelvin McCarron, who worked with the Hanson quarry manager on providing the bearing solution, elaborated further on the customer’s reaction.

“He was over the moon with them,” enthuses McCarron. “After successfully trialing the first conveyor, he asked us to swap out the rest of the conveyor bearings at the site with the Timken® Spherical Roller Bearing Solid-Block Housed Units. We only replaced those units in 2019 – almost nine years from their original trial. That’s a remarkable life for bearing units in this kind of application and environment.”

Both industry experience and product knowledge played a role in the recommendation of the Timken® Spherical Roller Bearing Solid-Block Housed Units.

“The solid steel housing of these units makes them pretty indestructible. They’re specifically designed to withstand conditions like those out at the Hanson Molong quarry, which is why we knew they would be a good fit – and we knew from our experience and knowledge exchange at BSC that other customers had achieved success in similar applications,” explains Phil. “Besides the cast steel – which can manage extreme loads and speed capacities – these units have multiple levels of sealing to protect them from harsh contaminants, which maximises their operational life.”

A drill designed for drillers

RTDrill has unveiled its latest down the hole (DTH) hammer drill rig, the RTD32, which is now available across Australia through CRAM.

The latest in the range of RTDrill’s surface crawler drill rigs is suitable for drilling diameters of 105 to 203 millimetres and a net drilling depth of 40 metres.

With 403kW engine options in the Tier III and Tier IV models, the RTD32 features a 1000 CFM compressor.

“The new RTD32 combines the efficiency, safety and functionality of the DTH drill rig in its class, combined with an affordable price tag,” says William Rogers, CRAM’s national product manager – surface mining equipment.

“A compact design with 12.55 metres length and 2.5 metres width makes the RTD32 a cost-effective model in terms of operation, transport and maintenance costs.”

The RTD32’s engineered safety controls include a falling object protective structure (FOPS) and a rollover protection system (ROPS) built to European standards. Two emergency stop buttons, one on the drill carriage and another on the control panel, allow immediate engine shutdown and compressor depressurisation. The cab is also equipped with a reversing camera and designed ergonomically for maximum driller comfort and safety, with the option for full MDG15 compliance from the factory.

The drill features a tilting and slewing system mechanism that allows operators to drill in all directions, even horizontally if necessary. The crawler can move at speeds up to 1.9 to 2.62 kilometres per hour and has up to 60 per cent gradeability.

Part of the Motion Asia Pacific business portfolio, CRAM specialises in fluid power, electro-hydraulic engineering and design, undercarriages and specialised maintenance and engineering services.

From multiple service centres across all states, CRAM offers full maintenance support for RTDrill products, facilitating maintenance, refurbishment, repairs and overhauls throughout the entire life cycle of the equipment.

“Our technical team can assist customers with drill rig component supply and service, as well as customisations and adding new machine options. Our clients benefit from access to factory level pricing supported by comprehensive inventory, workshop and site service capabilities,” Rogers says.
