Komatsu unveils D71PXi-24 dozer with new Clever Machine Management 2.zero tech (VIDEO)
Komatsu’s fundamental stage at ConExpo 2020 performed host to an all-new dozer and a major replace to its Clever Machine Management (iMC) platform.
The brand new D71PXi-24 on show on the present is a brand new mid-size dozer mannequin and the primary new Komatsu machine that may provide the second era of the iMC platform.

As a result of Komatsu was a little bit gentle on the small print with the brand new D71, it’s greatest to consider the exhibiting of that machine as extra a preview. The truth is, Komatsu hasn’t but introduced a concrete launch date for this machine apart from in some unspecified time in the future within the subsequent 12 months.
The D71 would be the largest hydrostatic dozer with factory-integrated machine management available on the market, Komatsu says. It’s powered by a 237-hp Komatsu diesel engine and can be in the identical measurement class as Komatsu’s D65 dozer fashions.
And other than its hydrostatic drivetrain, the opposite massive differentiator with the D71 is its design, as Komatsu senior product supervisor Jason Anetsberger explains.
“It’s in the identical measurement class as our current D65 dozer which is a traditional dozer—torque converter drivetrain. The D71, is our cab-forward design tremendous slant nostril and it’s an HST dozer,” Anetsberger says. “So it’s simply as massive as that D65— we’ve bought a pleasant 14-foot blade on there, 36-inch sneakers on this configuration, it’s bought 237 horsepower, [and weighs] 52,000 kilos, so she’s an enormous pushing machine.
“However with it being a hydrostatic and a brilliant slant nostril, it’s nonetheless very nimble versatile and permits the operators to get into tight areas. So it’s actually an attractive one-in-all machine that may do large hogging and may try this tight element work, giving the client the operator tons of flexibility on the jobsite.”
With the D71 Anetsberger says operators are going to discover a very comfy working setting and due to that tremendous slant nostril, visibility that he says is “unparalleled.”
“You may see your blade ideas, you may see all the things round you. You may see ahead and that’s not all the time the case in dozers on this measurement class which historically have had a really excessive hood and really restricted visibility out the entrance window,” he says. “That isn’t the case on this machine.
“…It’s tremendous comfy, tremendous nice visibility and if you begin pushing grime you’re going to understand the trip, the steadiness and the efficiency that this machine presents.”
The D71 may also characteristic Komatsu’s Parallel Hyperlink Undercarriage System. In any other case often called the PLUS undercarriage, it’s designed to climate excessive put on and tear because of a rotating bushing design. Komatsu says the system can last as long as twice so long as typical undercarriages and whereas eliminating downtime brought on by pin and bushing turns. The system may decrease restore and upkeep prices by as much as 40 p.c in sure purposes.
Let’s transfer on to clever Machine Management 2.zero. That is the primary main replace Komatsu has made to its iMC platform and Anetsberger tells us that it’ll present operators with extra automation options to make use of whereas making them simpler to activate and giving them the power to activate them extra typically.
“The imaginative and prescient behind iMC 2.zero is to provide operators and clients higher utilization of their automatics funding. GPS expertise prices further and we acknowledge that. So we need to ensure that these dozers and these machines are producing the utmost attainable with that expertise,” he says.
iMC 2.zero is made up of 4 elements that supply operators new automation performance:
The primary of those iMC 2.zero options, Proactive Dozing Management, is de facto the foundational characteristic of iMC 2.zero due to the large enhance in knowledge and setting recognition that it brings the platform.
And the characteristic itself has truly been obtainable since final summer time on Komatsu’s D51EXi and PXi and its D61EXi and PXi dozers. The large cope with this characteristic is that moderately than actually solely making sense to be used on end grading, Proactive Dozing Management is grade management that can be utilized 100 p.c of the time.
Which means it could actually carry out website cleanup, backfilling, auto-stripping, auto-spreading, excessive manufacturing dozing duties and extra.
Historically, grade management programs have solely centered on blade positioning. However Proactive Dozing Management additionally generates knowledge concerning the dozer’s tracks as effectively and that’s so the system has a extra full understanding of the bottom beneath the machine.
We’ve bought an entire separate video on Proactive Dozing Management that particulars the way it works so remember to verify that out beneath.
Now due to how rather more concerning the terrain iMC 2.zero understands, the platform is able to one thing referred to as Raise Layer Management. This enables operators to unfold fill from current terrain in additional constant layers. The characteristic works by measuring the terrain because it tracks over after which makes use of that knowledge to plan forward of its subsequent go. The characteristic is activated with a single button press and Komatsu says it could actually double manufacturing. Plus the extra constant layers make for extra high quality compaction.
Third up on the brand new iMC 2.zero options is Tilt Steering Management. This characteristic mechanically tilts the dozer’s blade in an effort to preserve the machine touring straight when you’re doing tough dozing. Clearly if the machine is touring in a straighter line, the reduce goes to be cleaner and extra predictable, however you too can consider this one as form of an operator consolation characteristic since Komatsu says that it finds that it reduces the necessity for operator steering enter by as much as 80 p.c.
Final however not least within the iMC 2.zero characteristic set is Fast Floor Creation. Operators can use this characteristic to create a brief design floor with one press of a button. The cool factor with this characteristic is that it actually helps you to rapidly create surfaces on the fly and Komatsu says that if you mix it with different iMC 2.zero features, operators can truly start stripping or spreading utilizing the automated modes whereas ready for end grade mode.
“So if [the operator] desires to degree out a pad, he can rapidly change the elevation of that, the mainfall of that after which the cross slope,” Anetsberger says.
Along with permitting operators to make use of computerized modes 100 p.c of the time, an enormous focus with iMC 2.zero was making it less complicated for operators to interact these modes. Fast Floor Creation is an ideal instance of that.
“Earlier than, let’s say you needed to make a easy floor, it could possibly be as much as 10 button presses to get by way of the menus….now we’ve got shortcuts the place it’s one button press,” Anetsberger says. “We’re not solely attempting to make the machine extra succesful however we’re attempting to make the machine simpler for purchasers to make the most of the funding that they’ve bought.”
