As a technical specialist in power transmission for CBC, it’s Milan Sreckov’s responsibility to assess the performance of power transmission equipment in customer applications. If the equipment is underperforming, he will propose an alternative solution – which was the case with one earthmoving customer.
“We had been working with this particular earthmoving customer for a while when an issue was raised about gearboxes on a head drum of their conveyor application – the conveyor was moving rocks and earth,” Sreckov explains. “It was breaking down every eight or nine months; that was the most they could get out of the gearbox.”
Sreckov went out to the customer site to perform an analysis.
“I completed some calculations on the motor and determined that the service factor on the existing gearbox was too low and not appropriate for the application,” he says. “This was the reason it kept breaking down. I recommended the customer change to an ABB gearbox solution.”
Specifically, the ABB Dodge Motorised Torque Arm II – better known as the MTA II – drive solution was suggested to the customer.
“We offered this solution to replace their existing gearbox, and it’s been almost two years now since the installation and they have not had any failures,” says Sreckov. “The customer is very pleased with this outcome.”
According to Sreckov, the ABB Dodge MTA II gearbox is well-suited to this type of application.
“These drives have been designed exclusively for belt conveyor applications – which is why the solution is excellent for a quarry environment such as the one we worked on with this customer case,” he says. “The Dodge MTA II has specific features that enable it to perform well in harsh conditions. For example, the lip-sealing system prevents ambient contamination from dust and other elements that could shorten the life of the gearbox.”
Moreover, Sreckov points out that ABB has a reputation for manufacturing high quality products for the mining sector.
“ABB is heavily involved in the mining segment in Australia and manufactures a range of drive solutions that have been designed with this sector in mind,” he expands. “We have confidence that the ABB gearbox solutions we provide to our customers are best in class. And customers stand to benefit from our expertise as well as the product offering of ABB, and our access to ABB’s technical expertise too.”
