New Cat D5 Dozer
Caterpillar has released details of its new D5 bulldozer, which will replace the D6N. More powerful and more manoeuvrable than its predecessor, the 170hp D5 features a fully automatic three-speed transmission with lock-up clutch offers faster cycle times, plus a redesigned cabin and a raft of technological advancements.
The Cat D5’s cab is more spacious and boasts a 10-inch touchscreen linked to a high definition rear camera. Compared with the D6N, the cab’s glass area has increased 15%, while a steeper angled hood provides 30% better forward visibility. Technology offerings on the D5 are led by updated, factory integrated Cat GRADE with 3D. Advanced Inertial Measuring Units (IMU) provide greater speed and accuracy without position sensing cylinders. Smaller antennas are integrated into the cab roof for even better protection and GPS receivers are mounted inside so they can be secured by locking the cab doors.
A more intuitive GRADE operator interface works like a smartphone, making it easy for operators to pick up quickly. Android OS platform allows installation of custom apps for more versatility. AutoCarry is included with GRADE with 3D to automate blade lift to maintain desired blade load, improving load consistency and reducing track slip. Additional GRADE technologies include Slope Assist, Indicate (showing the machine cross-slope and fore/aft orientation on the primary monitor) and Factory Attachment Ready Option (provides optimal mounting locations, brackets, and hardware and simplifies installation of an aftermarket grade control system). What’s more, the D5 also comes equipped with Cat LINK telematics technology.
Making the operator’s job easier are Hill Descent Control, Hill Hold, a Decel Brake Pedal (controls machine speed all the way to a complete stop, or for smooth inching control) and Steering Radius Control (uses steering and decel pedal input to automatically downshift for a tighter turning radius and more maneuverability).
The Stage V emissions compliant D5 is available in Standard or Low Ground Pressure (LGP) configurations, with either a push arm or Variable Pitch Angle Tilt (VPAT) blade. A folding VPAT blade is available to help meet regional transport width requirements. Waste, Forestry/Land Clearing and Fire Dozer configurations offer specialised factory-installed guarding and other features to help take on the toughest applications.
The update from D6N to D5 is part of an effort to make all Cat dozer model names simpler. Over the next couple of years, the Cat dozer range will be renamed from smallest to largest – D1 to D11 – with one model per size class and no more letter modifiers like ‘N’, ‘K’, ‘T’.
