Cat’s new 600-tonne mining shovel moves 61 tonnes per pass

Cat’s new next generation 6060 hydraulic mining shovel includes numerous design enhancements and new components that advance machine performance, durability and operator comfort. 

The new 6060 features updated engines, optimized hydraulics, heavy duty structures and undercarriage, Cat electronics and a state-of-the-art cab. 

The 600-tonne class mining shovel has a bucket payload of about 61 tonnes per pass in both face shovel and backhoe configurations. The 6060 is an efficient 4-pass match with the Cat 793 mining truck and 5-pass match with the Cat 794 AC mining truck.

The mining shovel is powered by twin Cat 3512E engines, which are optimized for high performance, fuel efficiency and increased durability. 

For the North American market, the engines are equipped with a maintenance-free diesel oxidation catalyst emissions control system, do not require diesel exhaust fluid and comply with Tier 4 Final regulations. The updated engine design also boosts reliability and extends time between overhauls by 10 per cent. 

The mining shovel’s engine and optimized hydraulics deliver 10 to 15 per cent improved fuel efficiency, compared to the previous face shovel model, with 3 to 5 per cent greater efficiency for the backhoe configuration. For reduced maintenance, engine oil and filter change intervals are now doubled to 1,000 hours.

Structural, undercarriage and slew ring upgrades help maximize uptime and productivity and lower cost per ton.

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 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.

Three-seat cab

The 6060 mining shovel features a new, state-of-the-art cab and operator station, equipped with a large floor window, expansive windshield and side windows. Unrestricted lines of sight to the crawler tracks and pit floor help the operator when repositioning the shovel and when loading trucks.

In the cab, the pneumatically-cushioned operator seat can be heated and ventilated. It has integrated joysticks and is multi-adjustable to offer optimal ergonomics. The innovative cab design 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. As well, 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.

Enhanced Motion Control, the first of several features within the available Operator Assist suite, is standard on the shovel. Enhanced Motion Control improves machine controllability and loading efficiency while reducing linkage and cylinder mechanical contact. 

The machine’s five-circuit hydraulics design also allows simultaneous control over two cylinder motions, two travel motions and swing to boost digging and loading efficiency.

Enhanced design

The next generation design of the mining shovel helps improve service efficiency by offering more room inside the service compartment and easy ground-level accessibility to the service station. The integration of Cat hoses in the design allows for local hose sourcing, while improved hose and component organization 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. Standard for the first time on the 6060, Product Link Elite enables data communication for remote machine health monitoring.

The 6060 comes ready to accept Cat MineStar Solutions, a comprehensive 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 for mines optimized for such machines.
