For just over a year, PT Manado Karya Anugrah has been using a fleet of machines from Volvo Construction Equipment (Volvo CE) to remove overburden at its coal mine in East Kalimantan, Indonesia. The fleet is now delivering exceptionally profitable operations for the coal mining contractor, thanks to their high productivity and uptime.
Together, the 10 R60D rigid haulers, six A40G articulated haulers and three EC750DL excavators produce roughly 1 million BCM per month.
“We chose Volvo over other brands because of the sheer productivity of the machines,” said Rafiuddin Djamir, owner of PT Manado Karya Anugrah. “Conditions at our site are tough and we know we can count on the productivity and reliability of Volvo machines to give us the lowest cost per ton.”
The site has medium to high gradients with limited room for maneuvering, but the Volvo CE rigid and articulated haulers make light work of the slopes. “Our operators particularly like the speed of the machines during a climb. They feel the machines have more power than others,” Djamir explained.
The Volvo R60D rigid hauler, in particular, has the highest rimpull power on the market, which makes it especially suited to high gradients.
The success of the machines at the site is also down to their high uptime. The machines work 22 hours per day in two shifts, seven days a week so any unexpected downtime would significantly impact production and, therefore, profitability.
“Overall, we have been extremely pleased with the productivity and uptime of our Volvo machines, as well as the high level of aftermarket support we receive from Volvo CE’s distribution partners in Indonesia,” Djamir said.
