Cat offers performance and fuel efficiency boost with new 777E haul truck

Cat has released its new 2021 Cat® 777E haul truck, a machine that, it says, features improvements in power, torque and transmission control to deliver best-in-class productivity, on top of a configurable Eco Mode operation to reduce fuel consumption and drive down cost-per-tonne of material moved.

One of the most popular trucks in its class, the new 777E offers the highest in-class payload of 98.2 t.

It comes fitted with an updated Cat C32 engine that delivers increased horsepower and a 7% improvement in torque to increase hauling performance. Optimised fuel mapping of the engine and adaptive economy mode, meanwhile, determine the most efficient operating point to improve truck fuel economy.

Additionally, operators can select a variable engine derate from 0.5% to 15% in Eco Mode operation to further reduce fuel consumption ‒ and the new automatic engine idle shutdown feature reduces fuel use and wear on engine components, Cat says.

Today’s 777E truck improves productivity by up to 5%, Cat claims.

“The new Advanced Productivity Electronic Control Strategy improves transmission and engine coordination to better utilise available engine power,” the company says. “The result is as much as 7% more torque delivered to the drive wheels for improved hauling performance. The new control system also provides smooth shifting for greater operator comfort.”

The 777E now offers a second gear start when underfoot conditions and grade allow. This feature enables the truck to reach optimum speed more quickly, lowers cycle times and minimises the number of transmission shifts. To save fuel, a new auto neutral idle tool shifts the transmission into a “neutral-like condition” when the truck is idling in drive, Cat explains. The transmission’s speed limit feature allows the machine to run at optimal gear for selected speed.

When working in cold conditions, the new auto-stall feature assists in quickly bringing the transmission to operating temperature at start-up. The effect is less non-productive time and reduced fuel consumed for warm-up, according to Cat.
The 777E also features a new gearshift lever with integrated hoist and park brake controls, which eases operation. The auto hoist feature delivers controlled truck bed descent to prevent body slams and increase component life.

A new touchscreen display features enhanced user interface options, the company says.

“Easy to read, it delivers improved navigation through machine control systems,” Cat says. “The new display allows operators to monitor key machine operating parameters, like tracking payload, as well as upcoming scheduled service intervals.”

Productivity enhancing technology

A host of newly integrated Cat technologies help to improve hauling efficiency and truck longevity on the 777E, Cat says.

The new Truck Production Management System (TPMS) integrates strut pressure sensors and on-board computing and displays truck payload to the loading machine operator. The system helps attain target payload, Cat says.

The Vital Information Management System on board the 777E allows operations to proactively manage machine health and production. Real-time machine performance, operating data and diagnostics are displayed on the in-cab monitor for easy viewing and troubleshooting. Integrated prognostics develop trends from cumulative collected operating data to help increase truck cycle efficiency.

A new “Tonne-Kilometer” feature helps ensure that truck operation falls within the operating range of the tyres. The system monitors payload, speed and ambient temperature to calculate operating conditions, and the operator receives an audible warning when conditions exceed tyre limits.

The updated 777E comes standard with Product Link™ with either cellular or satellite reporting options to meet the needs of the mine. Product Link captures critical machine operating data – location, hours, fuel, etc – and reports it back to the main office through VisionLink®, helping to improve productivity, truck use, safety and maintenance efficiency, Cat says.

Elevated safety

With integrated TPMS, the overload speed limiter works in conjunction with the improved truck payload system to automatically reduce travel speed when the truck is overloaded, according to Cat. Brake actuation is now fully hydraulic and delivers fast response and smooth application.

The new adjustable mirror package for the 777E improves rear visibility for the operator. An optional camera system delivers enhanced visibility for the operator to the machine’s front, rear and sides with the video feed displayed on the in-cab monitor.

Engine crank and machine lockouts disable the engine starter/secondary steering and implements to improve servicing safety, meanwhile. Lockout engagement is conveniently located at ground level and an indicator light display ensures lockout is effectively engaged, Cat says.

The new optional automatic lubrication system provides grease for all lube points on the machine, eliminating the need for manual intervention. The tank fill-point is conveniently located at ground level to improve refilling simplicity and enhance safety, the company added.

Cat bolsters earthmoving credentials with new 657 Wheel Tractor-Scraper

Caterpillar’s new 657 Wheel Tractor-Scraper (WTS) is billed as increasing productivity and enhancing operator comfort while delivering low-cost earthmoving, according to the OEM.

Featuring the field-proven, twin-power design to boost cycle times, the new WTS boasts a 7% increase in fuel efficiency over the 657G WTS, meaning more material is moved per unit of fuel burned. It also has improved onboard payload estimating accuracy to optimise productivity.

The 657 WTS is the largest open bowl scraper in the Caterpillar line, with a rated load of 46.4 t. It also has a more spacious cab to boost operator comfort and efficiency in high volume earthmoving, highway construction and mining applications.

“This new 657 is the next generation of ultra-class material moving systems,” John Gerhold, Wheel Tractor-Scraper Application Specialist for Caterpillar, said. “It delivers improved productivity, safety and technology, which our customers can use to strengthen their business today – and it is equipped to grow with them to meet tomorrow’s requirements.”

The 657 features on-the-go weighing through Payload Estimator, allowing the new WTS to achieve 95% load accuracy, so operators more easily reach target load goals, according to Cat. When working in colder climates, the Auto-Stall feature quickly brings the transmission to operating temperature at start-up, so the 657 gets to work faster. Ground Speed Control lowers fuel consumption by allowing the operator to set the desired top speed, allowing the machine to find the gear that works best for the engine and transmission.

The two-engine design includes the Cat C18 powering the tractor and Cat C15 in the scraper, both meeting US EPA Tier 4 Final/EU Stage V emissions standards. Its Advanced Productivity Electronic Control System, meanwhile, allows the machine to better use engine power and torque, resulting in more material moved throughout the shift. The transmission features Electronic Clutch Pressure Control, which improves shift quality and fuel efficiency. New hydraulic disc brakes improve braking performance and reduce maintenance.

With a 21% larger cab interior than the preceding model, the 657G, improves operator comfort and provides excellent visibility to the bail, cutting edge and bowl of the unit, Cat says. The air suspension comfort seat adjusts and rotates 30° to reduce fatigue, while the new Advance Ride Management adjusts damping to match ground conditions, resulting in a smoother ride for the operator. Automatic HVAC temperature control and defroster come standard for increased operator comfort, while a new power access ladder enhances operator safety when entering and exiting the cab.

The new high-pressure steering system requires less steering input, which bolsters operator efficiency and productivity, Cat says. Automatically engaging when the machine is in eighth gear, engine overspeed protection assists in slowing machine speed when approaching engine limits. Sequence Assist, a new option on the 657, automates many operator inputs each cycle to simplify machine operation.

The 657 tractor includes a new hydraulic on-demand fan that increases engine fuel efficiency. The machine also has draft-arm overflow guards, which prevent material accumulation between the draft arms and bowl sides. Ground-level access for fuel fill and all daily maintenance points increases service efficiency and safety to increase machine uptime.

Cat Product Link™, in tandem with the Integrated Payload Estimator, provide real-time payload, machine location, fuel usage and idle time information as well as diagnostic fault codes – all to significantly increase fleet management efficiency. A collective view of critical machine operating data is accessed via VisionLink® from anywhere there is an Internet connection.

Cat revamps 6060 hydraulic mining shovel

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.

One of these new-generation shovels is set to operate at Anglo American’s in-development Quellaveco mine, in Peru, as part of a fleet that includes autonomous 794 AC trucks.

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.
