The new 400-tonne-class Cat 6040 next generation hydraulic mining shovel is designed to help customers move more material while reducing operating costs.
The new design addresses modern mining challenges through productivity-enhancing features, durability upgrades and system improvements that increase efficiency.
“Customers are looking for ways to move more material without increasing fuel consumption or downtime,” said Nils Feddern, Caterpillar’s Senior Product Consultant for Hydraulic Mining Shovels.
“Similar to the next generation 6060, the new 6040 integrates proven Cat electronics infrastructure to help enhance performance and reliability, while a common design helps streamline maintenance and reduce downtime.”
Hydraulic optimization
To help customers reduce fuel consumption and extend component life, hydraulic optimization for the new 6040 features variable, on-demand hydraulic oil flow to reduce excess heat, conserve energy and prolong component life.
“With the new 6040 design, we focused on delivering high breakout forces and fast swing cycles while at the same time increasing fuel efficiency through hydraulic optimization,” Feddern said.
Conventional systems operate at the maximum required cylinder flow and pressure, regardless of demand from individual circuits.
The 6040’s optimized hydraulic system assigns individual pumps or groups of pumps to deliver the exact flow and pressure that each hydraulic function requires. This translates to a mining shovel that’s up to 15 per cent more efficient than machines without it.
Twin Cat C32B engines
To improve performance and reliability without sacrificing fuel efficiency, the 6040 is powered by twin new Cat C32B engines with 2,079-hp output that enable shovel operation or the ability to move the shovel off the face under the power of one engine. Multiple engine configurations are available to meet Tier 4 Final/Stage V emissions regulations without the need of DEF or China Nonroad Stage III emissions standards. When equipped with the optional oil change interval extension attachment, maintenance downtime is reduced through engine oil exchange intervals increasing from 500 to 1,000 hours.
The new 6040 also delivers high breakout forces of 269,996 foot-pounds in face shovel configuration and 252,460 foot-pounds with backhoe to prevent bucket stall when encountering tough materials.

Its closed-loop swing system delivers fast cycle times and improves energy efficiency. “One of the first things our field-follow machine operators comment on is the shovel’s power and swing speed,” Feddern said.
Standard Operator Assist – Enhanced Motion Control incorporates angle sensors on the linkage to calculate boom and stick positioning, preventing hard stops and metal-to-metal contact. By reducing pressure spikes and shock feedback, the system improves operator performance, reduces fatigue and extends component life.
The shovel delivers efficient pass-match loading for a range of Cat mining trucks. It loads the 147-tonne Cat 785 in four passes and offers eight-pass loading capabilities of the 327-tonne Cat 796 AC.
Comfort boost
The new state-of-the-art cab includes a floor window to provide clear views of the tracks and 40 per cent more visibility of digging and loading areas. Offering low, 68 dBA interior operating sound levels, the new cab design features a new air conditioning system, ergonomic joystick controls and left-side-mounted monitoring and diagnostic tower complete with large, 25-cm touchscreen, live sensor monitoring and visual and acoustic fault warnings.
Caterpillar’s three-seat design includes a fully adjustable next gen comfort seat, an elevated full-size trainer seat with a laptop work desk and a fold-away auxiliary seat to facilitate in-cab training.
Standard Vision 360 integrates four camera views on the in-cab touchscreen display to give the operator a 360-degree surround view of the shovel, reducing blind spots and repositioning and increasing safe operation. A new 45-degree hydraulically operated access stairway helps operators safely enter and exit the cab and features emergency lowering to ensure operation even when the engines are shut off.
Outside the cab, the 6040’s new hydraulic system helps to enhance operator productivity. Its unique five-circuit hydraulics allow for two-cylinder motions, two travel motions and swing.
Future ready
The designintegrates more standard technologies such as Cat Payload, which measures every bucket load to help customers consistently achieve target truck payloads without overloading or underloading, boosting load-haul cycle efficiency.
To help customers adapt to evolving technologies and future power options, the shovel’s new cab riser features integrated Cat electronics and an optimized electronic architecture. Standard ProductLink Elite boosts connectivity and increases the availability of machine reporting data. Plus, the design opens retrofit capability of Cat MineStar suite of technology solutions, including Fleet, Terrain, Detect and Health. The new design opens the door for power agnostic operation with retrofit capabilities of an electric power module for the next generation 6040.
Rugged structures
Built for demanding mine conditions, the new 6040 is engineered to last with a target design life of at least 60,000 hours. The shovel is 2.25 per cent heavier than the previous 6040 model and features robust structures and long-lasting heavy-duty fixed-axle rollers and idlers that eliminate grease consumption.
A new single line grease injection system paired with fixed pins architecture vastly simplifies the grease distribution system with component count and grease line reduction to all pins. This substantially reduces the risk of line breakage, simplifies diagnostics and allows for more efficient grease distribution and flow control.
A rigorous hose audit for the new shovel’s design provides better hose organization and routing for streamlined service and improved field performance that delivers thousands of operating hours without a major hydraulic leak.
All service areas are accessible via anti-slip walkways, and its retractable service station offers easy access to coolant, hydraulic oil, slew gearbox oil, grease, diesel and engine oil. Boom mounted, the main hydraulic block gives technicians quick access to the swing drives, rotary joint and travel spool valves, while increasing available space in the superstructure.
The updated electronics infrastructure provides access to the Cat Electronic Technician, helping dealer service personnel to more easily diagnose and prevent issues. Standard remote services include Remote Troubleshoot that allows the Cat dealer to diagnose issues remotely without impacting shovel performance and Remote Flash for updating onboard software at a convenient time without requiring a technician to be present.
