New Cat dozers will now not have letters of their mannequin names. Right here’s why.

In case you occur to note that a few of the mannequin quantity/letter designations on Caterpillar dozers are getting shorter, it’s not your eyes that want checking.

The corporate began reformulating its machine nomenclature again in 2017 with the top purpose of eliminating the letter suffixes that observe the numbers. Right here’s an instance from our unique article written by Marcia Gruver Doyle:

Below Cat’s former nomenclature system, for instance, the previous 745C would have change into the 745D. As an alternative, the brand new artic reads “745” on the machine’s facet with no letter designation, and the mannequin is thought by means of inside and exterior communications because the 745 (Construct 04), with the “04” representing the fourth technology of the machine.

Nonetheless, on the time the modifications to mannequin names began, Cat stated dozers can be the exception to the brand new rule. Now their considering has modified, and to be able to make dozer identification simpler and easier to know, the mannequin title modifications began three years in the past will now apply to dozers as nicely (plus, with the T-Collection Caterpillar was working out of letters).

“It follows an automotive technique,” says Sam Meeker, product utility specialist. “We’ve had a Ford F-150 for many years, however there has by no means been a Ford F-150 dash-1 or dash-2.”

Cat’s Sam Meeker talks by means of modifications on the brand new D5 dozer.

We noticed the primary accomplished change-over at Caterpillar’s Cary, North Carolina headquarters in October when the D6N was up to date and renamed the D5. And whereas a choice has not but been made about which dozers will carry the brand new badges at ConExpo 2020 in March (doubtless the D4 and D5 although nothing is about in stone), ultimately all of the dozers shall be renamed.

And inside the subsequent yr or so that you’ll even see a model new quantity designation, the D1, beforehand often known as the D3K2 and D3K. (See chart.)

The brand new numbers are primarily based on the horsepower class of every dozer mannequin. And to not fear, Cat’s not downsizing something. The outdated D6T is being rebadged the D5 nevertheless it truly weighs extra and gives extra horsepower than the D6T. (See our article on the brand new D5 by clicking right here.)

“This is a crucial change for us,” says Meeker. “We need to make sure that individuals perceive it and aren’t confused. The suggestions we’ve gotten has been constructive.” However as we’ve reported earlier than, the simplified numbering system isn’t going to be restricted to dozers. Finally the entire of Caterpillar’s gear lineup will endure a nomenclature simplification, a transfer that began with the 745 articulated truck in 2017.

Gradual roll-out

The dozer names aren’t going to be up to date all of sudden. Slightly, Caterpillar will rename every dimension class as soon as that dimension dozer has undergone a redesign or improve. The D6T, for instance, was renamed the D5 this fall in live performance with a number of latest options together with a mast-free GPS system, blade load monitor, traction management, new powertrain capabilities and a bump up in horsepower.

This isn’t to say that Cat dozer names gained’t have suffixes. A number of will stay. Due to their distinctive powertrains the hybrid diesel-electric drive dozers, D7E and D6 XE (launched in 2018) will retain the “E” and “XE” suffixes. And the LGP (low floor strain) tag shall be saved on all fashions which have the broader tracks.

The opposite suffix you would possibly ultimately see on the dozers is the GC designation, which is already used on some excavators (320 GC, 330 GC, 336 GC ) and one wheel loader (the 950 GC). The GC moniker was used to indicate a fundamental, no-frills machine with a decrease price and fewer expertise than the extra absolutely featured machines. Meeker says you would possibly/might see this on dozers a yr or two down the street.

Characteristic units

Previously, the suffixes on Cat dozer names usually designated completely different characteristic units. There’ll nonetheless be annual product updates and new characteristic units for dozers and different machines, however contractors might want to know the year-model or the serial quantity to know which machines have which updates.

“The mannequin yr does a reasonably good job of telling you what’s in there,” says Meeker. “However our clients are accustomed to serial quantity prefixes. The serial quantity prefix is like your center title. Understanding the serial quantity prefix and the characteristic set hooked up to it is sort of a badge of honor for our clients.”

Caterpillar dozers usually endure a redesign about each two to 5 years, says Meeker. “Relying on how massive of an replace that’s, we could do a serial quantity break. That enables us to be clear with clients and sellers as to when these options come into the road. For main modifications, on a bigger new product introduction, the place we’re altering important parts of the tractor we are going to do a full serial quantity prefix,” he says.

The D1 and D2

Along with renaming the dozer line, Cat’s reorganization of the nomenclature may also lead to a very new title, the D1 and the rebirth of the D2. The brand new D1 (the outdated D3K and D3K2) would be the first Caterpillar dozer to hold that quantity, says Meeker.

And whereas there was a D2 previously (produced from 1938 till 1957) the brand new D2 will incorporate the outdated D4K2 and D4K dimension class.

Three teams

General the brand new naming system may also clarify the three fundamental teams of dozers that Caterpillar gives. The primary group, the D1, D2, D3, and D4, will substitute the Okay household of dozers and retain their low-drive sprocket design. These are thought-about the light-to-medium obligation dozers. From D5 and up you’ll see the Caterpillar’s elevated sprocket/high-drive design. The D5 to D8 dozers comprise a second group of twin objective machines geared for each heavy dozing and end grading. And the third group, D9, D10 and D11 will proceed to be what they’ve at all times been—heavy push dozers.
