The Machine
Caterpillar introduced the earth moving world to the future in 2008 with the announcement of their revolutionary D7E electric drive track-type tractor. This all new machine is the descendant of a long line of mid-size dozers that have carried the D7 model designator since being added to the Cat line in 1938.
Separating the D7E from its competition and predecessors is its hybrid-electric drive train which reduces fuel consumption by 10 to 30 percent while improving the speed and power to ground efficiency rating by 10 percent. When combined, these increases result in an astounding 25% improvement in the material moved per gallon of fuel burned.
In addition to this unheard of increase in efficiency the reliability and uptime for the machine have been significantly improved when compared to conventional drive systems. In addition to a sixty percent reduction in the number of moving parts in the electric drive power train the new design utilizes components that offer up to 50% longer life. Even change intervals on hydraulic oil and filters has been increased by a factor of two and the power train oil and filters by an astounding factor of four.
While this machine deserves praise for its environmental benefits it also deserves recognition for the way it will lower operating costs and improve productivity in the construction community.
The Model
Everything expected from CCM for detail is readily apparent when you first look at the model. This includes individually linked tracks with tensioners, a movable blade, an attached winch that pays line out and in with ease, a complete cab interior and accurate markings. A closer look reveals opening engine covers with a fully detailed engine and access panels which when opened allow the cab to tilt and show the entire internal drive train on the dozer.
Overall length is approximately 9 ½ inches without the winch, overall width of the blade is 6 inches, track width is 4 ¼ inches, and stands 5 5/8 inches tall. With this new standard of die-cast model detail and such limited quantities this model will surely become another in the long line of “Truly Collectible” models from CCM.
Comes with a serial numbered certificate of authenticity that includes actual machine specifications. |
