Caterpillar introduce new D6 dozer
World’s first high-drive electric dozer offers new levels of grading performance and fuel efficiency
THE all-new Cat D6 dozer is said to deliver new levels of efficiency and performance with a choice of fully automatic powertrain (D6) or electric drive (D6 XE). At 161kW and with an operating weight range of 21.7–24.9 tonnes, the D6/D6 XE replaces the versatile Cat D6T bulldozer.
The D6 XE version is the world’s first high-drive electric-drive dozer, offering up to 35% better fuel efficiency and increased agility compared with the previous three-speed D6T model. It features a next-generation electric-drive system that offers high performance along with added durability. Simplified diagnostics and the serviceability advantages of a high-drive dozer help reduce service and maintenance costs.
The D6 version is powered by a four-speed fully automatic transmission that provides increased productivity and up to 20% better fuel efficiency versus its three-speed predecessor, whilst an additional gear between first and second ensures more seamless shifting.
Both powertrains are said to offer unprecedented ease of operation; the operator simply sets the ground speed and the dozer continuously optimizes for maximum power and efficiency based on load.
Caterpillar say jobs can be finished faster by grading at higher speeds with the new purpose-built Variable Power Angle Tilt (VPAT) dozer. The newly designed structure is stronger, yet lighter, so machine balance is optimized for grading without the need for a rear implement or counterweight.
A wide-gauge low ground pressure (LGP) VPAT design, with 915mm centred shoes, puts more track on the ground to achieve 0.73kPa (5psi) ground pressure, whilst a new, optional finish grading undercarriage has 10 bottom rollers for smoother grades at higher speeds, even on difficult surfaces like sand and gravel.
According to Caterpillar, overall jobsite productivity can be increased by up to 50% with a choice of Cat Connect GRADE technologies ranging from standard Slope Indicate to full factory-integrated GPS, all supported by Caterpillar and Cat dealers.
The factory Attachment Ready Option (ARO) on the D6/D6 XE provides optimal mounting locations, brackets, and hardware and simplifies installation of an aftermarket grade control system, making it easier to install any brand of grade control system, with specific mounting locations for grade control components.
In addition, Cat LINK telematics technology helps take the complexity out of managing job sites by gathering data generated by equipment, materials, and people and serving it up in customizable formats.
The new D6/D6 XE is designed specifically to reduce service and maintenance costs by up to 12%, with updated components, longer service intervals and fewer scheduled maintenance tasks. Easy access to grouped service points and regular maintenance items, plus a new ladder at the back of the machine, help reduce time spent on routine maintenance and inspection.
In addition, undercarriage updates are designed to save money and maximize service life. A new heavy-duty, extended-life undercarriage features positive pin-retention and link improvements for up to 20% more seal life in high-impact conditions.
The new Cat C9.3B diesel engine has a redesigned fuel system that provides greater durability and more accurate fuel delivery. Elimination of the NOx-reduction system and a simplified single engine electronic control module (ECM) help increase reliability.
The completely redesigned cab features a brand new 254mm touchscreen display that provides an easy-to-use operator interface. Distributed cab heating/cooling with automatic temperature and blower control circulates air more effectively around the operator, whilst integrated ROPS and 15% more glass area help increase visibility.
The D6/D6 XE is available in VPAT or push-arm configurations with a standard or LGP undercarriage. A variety of blade types, track shoe widths and rear attachments allow the machine to be optimized for various applications.
