Caterpillar has launched its next generation 6060 hydraulic mining shovel, which, it says, features multiple design enhancements and new components that advance machine performance, durability, serviceability, and operator comfort.
The new 6060, which replaces the 6060B in the hydraulic mining shovel lineup, features updated engines, optimised hydraulics, heavy-duty structures and undercarriage, Cat electronics and a state-of-the-art cab, according to the company. It is also fully integrated into Caterpillar product support systems for efficient Cat dealer services.
The 600-t class mining shovel has a bucket payload of about 61 t/pass in both face shovel and backhoe configurations. This makes it an efficient four-pass match with the 231-t payload Cat 793 mining truck and five-pass match with the 291-t payload Cat 794 AC mining truck.
Twin Cat 3512E engines are optimised for high performance, fuel efficient operation and increased durability, according to the company.
For North America, the engines are equipped with a maintenance-free diesel oxidation catalyst emissions control system, do not use diesel exhaust fluid and comply with US EPA Tier 4 Final regulations, Cat says. The updated engine design boosts reliability and extends time between overhauls by 10%.
The combination of this updated engine and optimised hydraulics enables 10-15% percent better fuel efficiency compared with the previous face shovel model, with 3-5% greater efficiency for the backhoe configuration, Cat says. For reduced maintenance, engine oil and filter change intervals are doubled to 1,000 hours.
Structural, undercarriage and slew ring upgrades help maximise uptime and productivity and lower cost per tonne, according to Cat. To boost longevity, the Cat undercarriage features heavy-duty rollers, idlers and tracks, along with a revised track tensioning system. The superstructure frame, face shovel and backhoe attachment structures, meanwhile, have been redesigned to reduce structural repair and extend service life via increased plate thicknesses and geometrical improvements. The slew ring design extends component life with a triple-race roller bearing and sealed internal gearing.
“The 6060 features a new, state-of-the-art cab and operator station with industry-leading visibility provided by the large floor window and expansive windshield and side windows,” Cat said. “Unrestricted lines of sight to the crawler tracks and pit floor aid the operator when repositioning the shovel and when loading trucks.”
A pneumatically cushioned operator seat can be heated and ventilated. It also has integrated joysticks and is multi-adjustable to offer optimal ergonomics.
This cab also includes two additional seats: a full-size seat and laptop desk for a trainer and a fold-up seat for an observer. The three-seat cab design is the first in this size class of shovels, Cat says.
Improved sound suppression on the power module keeps spectator sound levels low, while the sound suppressed cab provides a quiet working environment for the operator, according to the company.
The first of several features within the available Operator Assist suite, Enhanced Motion Control is standard on the shovel. This improves machine controllability and loading efficiency while reducing linkage and cylinder mechanical contact, according to Cat.
The machine’s five-circuit hydraulics design allows simultaneous control over two cylinder motions, two travel motions and swing to boost digging and loading efficiency, the company added.
The next-generation design helps improve service and maintenance efficiency by offering more room inside the service compartment and easy ground-level accessibility to the service station, Cat says.
Integration of Cat hoses in the design allows for local hose sourcing, while improved hose and component organisation further reduces machine downtime.
Sensors located throughout the 6060 monitor operating data, record faults and give audible and visual notifications of issues to the operator. Product Link™ Elite, which is standard for the first time on the 6060, enables data communication for remote machine health monitoring.
The 6060 comes ready to accept Cat MineStar™ Solutions, a suite of mining technologies geared to enhance mine safety, improve efficiency and reduce operating costs.
In addition to the next generation diesel-powered 6060, Caterpillar continues to offer the electrically powered 6060 AC FS (face shovel) for mines optimised for such machines.
