Tech boost for next-gen Cat D8

Caterpillar has pulled the covers off its new Cat D8 dozer, with the manufacturer claiming the next-generation machine features a host of new tech, while also making it easy for operators to switch between machines of different sizes.

Cat’s C15 engine has more horsepower compared to its predecessor to tackle a wide range of dozing, ripping and grading tasks, while the C8’s elevated sprocket is said to offer better drive and balance than low-drive undercarriages.

A completely redesigned cab is now more spacious and more comfortable, thanks in part to a new and wide air suspension seat with a broad range of adjustment. With an integrated rollover protective structure (ROPS), Cat says the new cab offers an improvement in visibility of over 17 per cent, while the cab can be removed for servicing in around 30 minutes.

The 10-inch touchscreen gives operators an overview of the machine and its technology and even offers helpful tips. The reversing camera helps keep personnel safe on busy worksites, while the effective HVAC system keeps operators comfortable year round, while reducing fogging or frosting in adverse conditions.

Assist technology features minimise operator input, boosting productivity for less experienced operators and decreasing effort and fatigue for everyone, while delivering quicker and more precise outcomes. Cat Assist with Attachment Reader Option (ARO) standard features include:
• Stable Blade to work seamlessly with operator inputs to help produce a smoother surface when operating manually
• Traction Control automatically reduces track slip to save time, fuel and track wear
• Steer Assist reduces steering inputs by automating track and blade tilt steering
• Blade Load Monitor leverages GPS and provides real-time feedback on current load versus optimal blade load, based on ground conditions, and actively monitors machine load and track slip
• AutoRip automates ripper raise/lower and shank in/out positioning to maximize ripping productivity
• Attachment Ready Option (ARO) provides wiring and mounting for faster installation of dealer-installed options like Cat Grade with 3D, AccuGrade, Universal Total Station (UTS) or other grade control systems
• AutoCarry uses a GPS signal to automate blade lift, helping to maintain consistent blade load and reduce track slip
• Cat Grade with Slope Assist automatically maintains pre-established blade position without a GNSS/GPS signal
• Slope Indicate shows side slope and uphill/downhill grades to help operators with slope work

Cat Command for Dozing removes the driver from hazardous environments and affords remote control operation. Each new D8 is factory remote control ready, with a plug-and-play roof-mounted remote control unit installed at the dealership.

With no on-site network requirements, the portable and lightweight Command console provides quick and efficient line-of-sight remote control from up to 400m for optimum operator visibility. The Command station delivers comfortable, non-line-of-sight operation either on-site or from miles away. The station features a comfortable seat, familiar controls and allows the use of Grade, Payload, Assist and other technologies using the included touchscreen.

The new D8 comes with a higher level of connectivity, with Remote Troubleshoot allowing Cat dealers to perform a range of remote diagnostic testing. Remote Flash affords on-board software updates without a technician, while customisable dashboards can streamline fleet management efficiency.

The D8 dozer leverages VisionLink to provide actionable data insights, accessed anywhere a connection is available through Cat Product Link for all connected assets, regardless of fleet size or manufacturer.

Meanwhile, Cat’s D8 Waste Handler is optimised for challenging landfill operating environments. Specialized guarding, striker bars and seals help protect the machine and undercarriage from impact, material wrapping and airborne debris.

Impact-resistant polycarbonate cab doors eliminate the need for door screens, while lights are mounted high on the dozer, away from the debris for protection, to illuminate the work area.

The configuration features a high debris cooling system with automatic reversing fan, cooling system swing-out cleaning access, laminated thermal shields and insulated Clean Emissions Module. Its waste undercarriage with centre-hole track shoes and landfill-specific blade designs help to optimise performance.
