Cat Unveils New D7 Dozer: Greater, Stronger, Smarter (VIDEO)
A day earlier than the crowds descended upon ConExpo-Con/Agg 2020 in Las Vegas, Caterpillar unveiled it’s all new D7 dozer mannequin. The brand new D7 packs extra energy, extra weight, and probably large productiveness positive aspects over its predecessors.
You’ll be able to take a look at all the small print on this video or learn on under.
As has been the case with all of Cat’s new machines within the final 12 months or so, the brand new D7 is topic to Cat’s new naming conference that drops letters from its mannequin names. As such, this new D7 replaces the D7E and D7R.
The brand new D7 incorporates a Excessive Drive undercarriage design that Cat says supplies a smoother journey, higher stability due to a decrease middle of gravity, lengthy monitor life and simple clear out of collected filth and different materials due to all of the room between the monitor and the curler body.
Cat says the Excessive Drive undercarriage can also be simpler to restore and rebuild due to modular element design.
The D7 shall be accessible in customary or low floor stress configurations with a wide range of blade and monitor shoe decisions.
Cat dozer product supervisor Sam Meeker informed us that Cat felt the previous D7E was a bit too shut when it comes to functionality to the brand new D6. So, on this new D7, Cat has bumped up the burden, horsepower and blade measurement to get this machine’s charts nearer to that of the D8
The D7 is powered by a Cat 9.3B engine delivering as 12-percent bump in horsepower to 265 hp and incorporates a absolutely automated 4-speed transmission just like the one discovered on the D6 and D8T.
Cat bumped up the burden of the D7 by about 6 %. The machine now weighs in at a variety between 62,000 and 65,000 kilos relying on the configuration. Blade capability on the D7 has elevated by 10 %.
Along with the spec bumps, the D7 additionally options increased drawbar energy and improved winch and ripper efficiency.
The consequence? Cat says you’ll be capable to transfer as much as eight % extra materials with the brand new D7 than you have been in a position to transfer with the D7E.
And the D7 isn’t just a rebadge of the D7R, which additionally featured a excessive drive undercarriage. The D7 delivers a productiveness increase of 11 % over the D7R whereas being eight % extra gas environment friendly. Plus the brand new blades on the D7 are bigger and it has the brand new 4-speed automated transmission that the D7R lacks.
The D7 additionally options the upgraded, redesigned cab discovered on the brand new D5 and D6 dozer fashions. The cab options extra space, higher visibility, a extremely adjustable seat and controls for extra consolation and a 10-inch touchscreen show. A high-definition rearview digicam is customary.
The opposite half of the potential story on the D7 is the massive productiveness positive aspects that Cat says could be achieved by equipping the dozer with a number of operator help applied sciences.
These embody slope point out, slope help, Cat Grade with 3D, a blade load monitor, Cat’s second technology Secure Blade function, traction management and AutoCarry, a function which robotically lifts and lowers the blade to take care of extra constant blade hundreds and restrict monitor slip.
When making use of those applied sciences, Cat says operators can enhance productiveness by as much as 50 % on the D7 over the D7E.
Lastly on the know-how aspect, you may order the D7 distant management prepared with wiring and direct from the manufacturing facility.
Waste/Landfill, Forestry and Pipeline configurations of the D7 will even be accessible from the manufacturing facility. Every of those specialised configurations are closely modified with purpose-built parts, application-specific undercarriages and speciality blades.
