Cat’s new D5 replaces the D6N, boasts new tech and options for steadiness between heavy dozing, end grading (VIDEO)

The dozer and its design outlined Cat. They nonetheless name them “track-type tractors,” in step with the heritage. So when Cat comes out with a brand new mannequin it’s like bringing a toddler into the world. Get away the cigars.

This newest version to the household, the D5, inherits all of the technological DNA of earlier dozers plus a few new GPS-driven options along with extra weight and horsepower. The purpose is to make this dozer equally succesful at heavy dozing and end grading.

You’ll be able to take a look at our full video interview and overview for the D5 slightly below or learn on for all the main points.

Let’s speak in regards to the expertise first.

The GPS system has been hidden out of sight, save for an antenna on the highest of the cab, protected from harm and thieves. The machine and blade orientations are calculated by inertial measurement unit (IMU) sensors on the blade and the physique of the machine.

It’s all built-in on the manufacturing facility and known as Cat Grade with 3D. The operator interface on the monitor works like a wise cellphone with contact display screen fashion pinching and swiping performance. The 10-inch monitor for GPS operations is separate from the primary machine monitor within the middle of the console.

The Secure Blade function has been round some time however improved for the brand new D5. “It’s somewhat extra correct and quicker and considerably simpler to make use of,” says Sam Meeker, product utility specialist. It additionally makes use of blade positioning info from the IMUs to detect sudden or jerky actions of the blade. When it senses these, it sends directions to the hydraulics to even out abrupt variations leading to clean, gradual transitions from one blade peak to the following. This helps produce a smoother floor and eliminates washboarding, making—because the saying goes—good operators higher and novice operators good. These small efficiencies, over the course of a day additionally add as much as improved productiveness.

Slope Help routinely maintains a blade slope setting once you don’t have a GPS sign or laser to information you. It mainly does the identical factor because the previous, gravity-based angle indicator gauges besides you don’t should eyeball the gauge on the again of the blade. With Slope Help, your fore-aft tilt and side-to-side blade angle present up on a monitor within the cab. You’ll be able to program the values you need on the display screen and even let go of the joystick and the machine will proceed on the slope parameters set on the display screen.

The D5’s new expertise options embody Blade Load Monitor and Traction Management. These faucet into info coming from a further GPS sensor. The Blade Load Monitor detects sudden adjustments in velocity and/or observe slippage and shifts right down to maintain the load beneath energy. In comparable trend the Traction Management briefly reduces observe energy when slippage is detected so you possibly can modify the blade load to forestall productivity-robbing slippage. The visible indications that information the operator are gamified—you see a inexperienced/yellow/pink bar and simply maintain

it within the inexperienced for the optimum traction. “Each push in a dozer prices you one thing,” says Meeker. “You would possibly as properly make it the perfect push you possibly can.”


Energy and productiveness

The D5 goes to switch the D6N within the household for now, however really weighs 400 kilos greater than the D6N within the XL bundle and 1,800 kilos further within the low floor strain (LGP) configuration. The engine bumped up 4 horsepower to 170 ponies. The additional weight and energy add as much as a 4.5 % improve in drawbar pull and a pair of.5 % enchancment in productiveness, says Meeker.

Cat additionally put collectively a bundle of enhancements it calls “enhanced energy practice management” to drive further effectivity in dozing operations with the D5. Hill Descent Management maintains your velocity when cresting a hill and heading down with out the necessity to bounce on the service brake. And Hill Maintain routinely engages the brakes to carry you in place when you’re in impartial. The Steering Radius Management makes use of sensors on the steering and the decel pedal to routinely downshift anytime you need to crank the dozer round in a good turning radius.

Guide shifting has been eradicated on the D5. A totally automated, 3-speed transmission shifts gears seamlessly permitting for smoother acceleration and quicker cycle time. The D5 is accessible in normal or low floor strain (LGP) configurations with both a push arm/SU blade (semi-U formed) or a variable pitch angle tilt (VPAT) blade. If it’s worthwhile to meet regional transport necessities, a folding VPAT blade is accessible. The brand new purpose-built push arm configuration for the SU blade places the middle of gravity a bit additional ahead for higher chopping and penetration.


The cockpit

The previous D5 had one of many smallest cabs in its class, the D6N had one of many largest. So Cat put D6 dimension cab on the brand new D5. In addition they moved the exhaust stack to the facet and built-in the A-pillar into the ROPS to enhance visibility. A steeper slant over the hood additionally improves visibility to the blade. The seat is heated and ventilated and adjustable 13 methods. A high-def rearview digicam brings up a panoramic view behind the dozer anytime you place it in reverse.

Security acutely aware operators may also recognize a “halo” seize bar that runs fully across the circumference of the cab—one thing to hold on to when cleansing the cab glass. A seize bar within the again offers you a gradual maintain when refueling as properly.


What’s in a reputation?

As talked about, the D5 will substitute the D6N and displays Caterpillar’s plan to make dozer mannequin names less complicated.

The D6K will turn out to be the D4, the D5K will turn out to be the D3, D4K will turn out to be the D2 and D3K will turn out to be the D1. Finally the dozers can be identified by simply their dimension class, D5, D6, D11 and so forth. Cat began the nomenclature change course of final yr and ought to be totally transitioned by the top of subsequent yr.
