Stick-steer journey on Cat’s new 306 CR XTC excavator offers you skid-steer performance in a digging machine
We gave you a primary have a look at the brand new Cat 306 CR compact excavator from the ICUEE present a month in the past. You possibly can see our preliminary video protection right here.
However extra just lately we acquired a full look and correct demo of this machine at Caterpillar’s BCP headquarters in Clayton, North Carolina. Beneath we’ll run by the specs for you, however one factor that stood out to us that didn’t get a variety of emphasis within the press launch was what Cat calls “stick steer” by which they imply joystick steering.
No massive deal you say? Have already got that on skid steers? Sure, however if you put the journey features on the left hand joystick of an excavator fairly than the ground pedals and levers it seems you are able to do a complete lot extra with this than another design. Right here’s why.
You possibly can try our in-depth video breakdown of the 306 slightly below, and skim on to seek out out extra.
Load and carry
The 306 CR is available in three variations: a normal straight blade, an influence angle blade and an XTC or further device service model. The XTC is the place it will get fascinating. This design makes use of a clamshell model bucket on the entrance. You possibly can open up the bucket and doze as you’ll with a straight blade but additionally load the bucket, decrease the highest half of the clamshell and trip away with a full bucket of fabric. You possibly can even dig up a bucket of dust or materials with the increase and stick and drop it into the clamshell for high-output load-and-carry.
That’s the place the stick steer journey comes earns its maintain. As a substitute of pushing ahead on the ground pedals and awkwardly leaning ahead along with your left hand on the steering levers, you’ll be able to sit again within the seat, work the journey operate on the joystick and comfortably take this load into the following county if want be. Cat left the ground pedals and steering levers within the cab anyway, however these could be eliminated with simply 4 bolts. You turn between the 2 journey kinds with only a click on on the joystick.
Backfilling a trench with any of those blades additionally will get rather a lot simpler with the stick steer journey. Once more as an alternative of the awkward forward-leaning posture, you sit again within the seat and make minute changes with the joystick. Doing this with the journey levers and ground pedals is all the time a bit jerky—you might be off steadiness the entire time. Doing it with a joystick makes you extra snug, exact and in the end productive. Stick steer additionally provides creep management which simply makes that journey operate even higher, particularly when it’s important to journey with the cab perpendicular to the tracks. It is going to be provided on all Caterpillar Subsequent-Gen excavators from 1.5 to 10-ton.
This load-and-carry capability of the 306 CR XTC offers it primarily a number of the identical functionality as a skid steer or compact observe loader. Granted these two machines can do the work sooner, however for the proprietor operator or a man who will get caught working solo on a job with no help tools that is—dare we are saying it—a sport changer.
All the remainder
All of the 306 CR mini excavators include a 59.9-horsepower Cat C2.4 turbocharged engine. Weights vary from 14,299 to 15,821 kilos. The “CR” right here stands for compact radius, not fairly zero tail swing, however at 58 inches, shut sufficient for many tight jobsites. Normal dig depth is 146 inches, and with the lengthy stick choice you’ll be able to dig down 162 inches.
Cat pumped up the hydraulics on the 396 CR particularly to assist out with the flexibility to carry further weight on the tip of the stick at a distance. At a 9.eight foot radius it is going to raise as much as 7,839 kilos utilizing its load sensing, variable displacement hydraulic pump pushing out 46 gallons per minute. The auxiliary hydraulic circuit places out 24 gpm. All three fashions can use entrance shovels with pin on buckets or couplers. Hydraulic thumbs are additionally out there in sure areas.
The cab is sealed and pressurized, however a ROPS mannequin can also be out there. A brand new 10 inch colour monitor within the machine means that you can set operator preferences, jog dial for easy navigation, regulate machine efficiency parameters and maintain observe of upkeep wants. The monitor is Bluetooth enabled, which implies you’ll be able to reply cellphone calls within the cab with out taking your arms off the controls—a pleasant characteristic for the man who runs his enterprise from the operator’s seat.
