Ontrak Engineering (a local specialist in the design, manufacture and overhaul of mining equipment) has expanded its footprint to supply turnkey solutions to a customer in Indonesia. This move comes in partnership with HMA Group, a manufacturer and distributor of capital plant equipment in the region.
This was not Ontrak’s first project for delivery in Indonesia, and according to company managing director, Steve Lewry, it won’t be their last. “We intend to expand our footprint in Indonesia and capture a higher percentage of the market for this type of equipment over there,” he said.
Bonfiglioli’s contribution was integral to this project. “The end user was looking for a cost effective, yet technically superior product, and felt that the Australian Made Ontrak/HMA Group Products fitted the criteria for all parameters. The Bonfiglioli project team supplied drives tailored exactly to the contract requirements, offering the customisation, flexibility and product delivery needed for us to achieve the right solution,” Lewry said. “In addition, Bonfiglioli also provided a very detailed customer centered FAT (Factory Acceptance Test), which was met with enthusiasm from the end user team that witnessed this procedure.”
The end user – a coal mining project – required a very specific pick roll or breaker solution that breaks coal down into smaller product for more efficient transportation and processing. Bonfiglioli supplied a complete solution to power the breaker, comprising of HDO gearbox with an Australian-designed and manufactured Alignment Free Drive (AFD) bell housing to accommodate the fluid coupling, as well as a high-power, 185kW three-phase electric motor with IP66 protection. “This is a quality product with extremely good reliability under mining conditions,” Bonfiglioli Transmission (Australia) NSW sales engineer Alex Kolc commented.
The HDO 140 gearbox is a heavy-duty right-angle helical-bevel gearbox, designed to reduce motor speed and increase torque and is ideal for demanding mining applications. “In this case, we supplied a geared motor variant with a cooling radial fan on the input shaft, to dissipate heat under heavy-duty or continuous loads,” Bonfiglioli national sales manager Harry Singh said.
The unit’s bell housing and guard assembly ensure the geared motor is safely connected to the fluid coupling. This coupling is commonly used in heavy-duty or variable-speed applications because it reduces mechanical stress and delivers smooth torque transmission with built-in overload protection.
Together, these features help control start-up torque, absorb shock loads, and provide seamless power delivery.
“The drive arrangement includes an overload mechanism within the fluid coupling, that if triggered, shuts the machine down if a jam occurs, protecting the gearbox from damage,” Kolc added.
Following a successful FAT process, the complete breaker solution was recently dispatched to the end user for installation.
A valued partnership
Elaborating on the 18-year long relationship with Bonfiglioli, Steve notes: “Ontrak and Bonfiglioli have never had an issue that could not be resolved in 5 minutes. Their product is remarkable – we have had zero recalls or failures in this time. The team is easy to work with, responds quickly and always strives to give us what we need for major tender responses. This partnership will continue to kick goals together well into the future.”
