Caterpillar has unveiled a new hydraulic mining shovel.
The Cat 6015B hydraulic shovel builds upon the former Cat 5011B shovel, and provides greater tonnage removals at a more productive rate.
The 100 tonne machine features a large standard bucket and a payload capacity of 14.6 tonnes, “this design translates to fast cycles and a pass match advantage over leading standard-equipped shovels in its class when loading trucks of 55, 65 and 90 tonne capacities.”
It comes with a single Cat C27 ACERT engine that provides 606kW of rate power.
The large, 8.1-cubic-meter standard bucket, outfitted with Cat C70 hammerless GET, further boosts production capability.
With the standard bucket, the 6015B is optimised to fill a Cat 773 truck in four passes, a 775 in five passes, and a 777 in seven passes.
The machine has a boom float feature that regenerates book oil for reduced engine demand, an oil cooling system that is independent of engine cooling, and is capable of regeneration of swing energy via its closed-loop swing system, all of which add to greater overall fuel efficiency.
Designed with Cat’s automatic flow proportioning technology, it has more efficient hydraulic pump utilisation, reduced energy loss, and increased fuel savings.
“Exclusive Cat Proportional Priority Pressure Compensating technology ensures that hydraulic flow is proportional, according to demands, so individual functions—boom, stick, and bucket—are automatically prioritised during simultaneous operations,” Cat added.
This aids smooth, efficient operation and controllability.
Pressure and flow compensation deliver only as much flow as needed, the result of which is reduced heat build-up and component wear.
The boom and stick utilise high strength steel and rugged castings that are joined and thermally stress relieved for optimum structural life and resistance to impact and wear in difficult digging conditions.
Its box section design provides superior rigidity and strength, and heavy duty castings are used in high load areas to add exceptional strength and durability.
A newly designed hydraulic filtration system has also been built into the machine, where a separate kidney loop provides continuous filtration and optimum oil cleanliness at all times for greater consistency in oil cleanliness.
Safe movement around the machine has been a focus in design, with well engineered access and egress with walkways for safe movement around the machine and an optional 45-degree powered access stairway.
Wire and hose guarding facilitate safe maintenance, and numerous and optimally positioned lights, mirrors, and E-stop buttons further improve safety.
The operator cab offers large, wide windows, which provide excellent all-around visibility of the work environment, contributing to the operator’s situational awareness during digging, loading and travel.
The cab is pressurised to keep dust out, while the climate control system is fully automatic which allowing for consistent in-cab temperature and operator comfort in any weather conditions.
Like other Cat machinery, it features MineStar, VIMS and Product Link for improved productivity, maintenance and equipment management.
It is currently only available in a backhoe configuration.
