COVER STORY

The new Cat 6015B hydraulic

Barloworld Equipment prides itself on its ability to sell and support the earthmoving requirements of customers across the spectrumwith a comprehensive range of Cat® load and haul combinations. Caterpillar’s new 6015B hydraulic shovel illustrates this strategy, coming into the Southern African market as a loader that comfortably fits the gap between legacy Cat hydraulic excavators and the larger Cat mining shovels.

T he Cat 6015B has the flexibility to work in heavy construction, quarry/aggregate, and small to medium size mining applica- tions, says Bongani Sibeko, Prod- uct Manager: Mining at Barloworld Equip- ment. “This machine will also help contract miners to produce more material at less cost, meet production targets and maximise profitability.

“The Cat 6015B builds on the legacy of the popular Cat 5110B shovel, which has always been known as a robust and reliable digging machine. “The 6015B has an operating weight of 140 tonnes with the

most powerful engine in its class at 606 kW,” continues Sibeko. “The standard heavy duty bucket is also one of the largest in this machine class with a capacity of 8,1 m³. The combination of powerful engine and bigger bucket provides faster cycles and one pass-match advantage with Cat 773, 775 and 777 trucks over compet- ing machines with standard buckets.” He adds that the extensive use of Cat compo- nents such as the HEX cab, D11 track links and robust 5110B mining linkage assure the quality of the Cat 6015B. Efficiency The 6015B is powered by a Cat C27 ACERT™ engine rated at 813 horsepower that gives it the edge in digging power and cycle times. The 8,1 m³ bucket, using Cat C70 hammerless GET, is optimally suited to fill a Cat 773 truck in four passes, a 775 in five passes, and a 777 in seven passes. Manufactured at Caterpillar factories in Dortmund, Germany, and Batam, Indonesia, the Cat 6015B is currently available only in a back- hoe configuration. The Cat 6015B is both powerful and efficient.

In controlled tests, this machine has delivered a strong production advantage in pure tonnes produced over similar specification competi- tors, coupled with better fuel efficiency per tonne produced. Fuel efficiency is boosted by several specific features, including Caterpillar’s proprietary integrated engine control technologies, a boom float feature that regenerates boom oil for reduced engine demand, an oil cooling system independent of engine cooling, and regeneration of swing energy via a closed-loop swing system. Cat automatic flow proportioning technol- ogy creates more efficient hydraulic pump utilisation, with less energy loss and more fuel savings. Exclusive Cat Proportional Priority Pressure Compensating technology ensures that hydraulic flow is proportional according to demands so that individual boom, stick and bucket functions are automatically prioritised during simultaneous operations. This aids smooth, efficient operation and controllability.
