Custom engineering by Bonfiglioli Transmission (Aust) is helping a local manufacturer win new markets despite a high dollar and global economic uncertainties.
Ontrak Engineering, a wholly owned Australian business specialises in the manufacturing and overhaul of underground coal mining equipment serving some of the world’s leading resource companies.
Ontrak’s latest success came this year when it teamed with Bonfiglioli Transmission (Australia) to take out first place in the Australian Bulk Handling Awards in the category of Excellence in the Application of Gears, Motors or Drives. The award follows an award won earlier in the year from Good Design Australia.
Ontrak’s award entry partner at the Australian Bulk Handling Awards, Bonfiglioli Transmission Australia provided custom-engineered alignment-free drives and specially adapted A series and HDO series helical bevels and 711 series mobile travel drives for the Ontrak feeder breakers used at BHP Billiton’s underground Appin coal mine in New South Wales.
According to Managing Director of Ontrak, Mr Steve Lewry, the track drive system is designed to work on all floor conditions with different track widths for ground pressure issues. The crusher breaker’s entire deck system is lined with chromium laminate wear-resistant material for durability and reliability.
Ontrak’s customer base includes many world-class resource companies such as Rio Tinto, Xstrata Coal, Gujarat NRE, Centennial Coal, Solid Energy NZ and Peabody Coal among others.
Ontrak chose Bonfiglioli drive combinations featured in the successful entry for the Australian Bulk Handling award for their superior technology, innovative Australian engineering and total reliability in arduous conditions.
Bonfiglioli supplied Ontrak Engineering with conveyor, crusher and travel drives for three feeder breakers working in underground conditions at the Appin mine.
Bonfiglioli’s diversified product range also enabled Ontrak to get three different kinds of geared motors for use in its Australian designed-and-built feeder breakers.
The machinery’s crusher uses a Bonfiglioli heavy duty bevel helical HDO gear box in an alignment free (AFD) configuration with a built-in slip for coal crushing. Engineered at Bonfiglioli HQ in Sydney, the AFD configuration further extends the versatility of the HD series of advanced heavy duty drives by introducing an alignment-free configuration that cost-effectively integrates the motor and gearbox.
The AFD design offers an alternative to laser-aligned baseplate types that allow the use of close coupled IEC B5 flange mounted motors up to a G315 frame size.
The conveyor also incorporates a smaller Bonfiglioli A90 helical bevel gearbox modified with a hydraulic motor to provide the conveyer drive to bring the coal to the crusher. Lastly, the whole feeder breaker is made mobile by track drives running Bonfiglioli’s 711 hubs with a releasable brake system to allow for towing.
Bonfiglioli’s HD AFD design joins their expanding range of Australasian-engineered mounting options for specific applications. The HD AFD combinations, available in capacities up to 1722 kW and 150,000 Nm complement Bonfiglioli’s High Torque drives and offer quick, trouble-free assembly and maintenance of high speed components including fans, fluid couplings and brakes.
Mr Lewry added that they chose Bonfiglioli products because of their excellent support staff, local assembly of their drives and motors as well as their superior quality.
Managing Director of Bonfiglioli Transmission (Australia) Pty Ltd, Mr Malcolm Lewis comments that the HD AFD models can save both time and money in a range of applications because there is no need to laser-align the motor and gearbox shafts.
Applications include conveyor drives, shuttle drives, bucket elevators, inching drives and other materials handling equipment.
Bonfiglioli Transmission Australia’s Drives Service Centre, coupled with local assembly of HD heavy drives enables the company to respond quickly to industry’s rapidly developing needs for drives to avoid costly delay or downtime in mining and heavy engineering installations.
The DSC also allows Bonfiglioli to promptly and precisely custom engineer drives to optimise performance for particular applications, especially in non-standard mining applications.
