Caterpillar releases line of low-emission small dozers
The D1, D2 and D3 Next Gen dozers replace the D3K2, D4K2 and D5K2 models
Building on the same base machine platform as their predecessors, the new Cat D1, D2 and D3 Next Generation small dozers feature styling changes, technology enhancements and a new low-emission fuel-efficient engine that provides significant value for the user.
These Next Gen small dozers are designed to optimize speed, transportability, maneuverability, versatility and finish grade accuracy. A new lower sloping hood line improves visibility over the top of the hood to the peripheral view and blade's cutting edge to increase finish grade efficiency.
Reducing track slip when the machine encounters maximum load for greater productivity of each cycle, standard Automatic Traction Control no longer requires operator interaction as with previous models. Slope Indicate improves operator confidence when working on slopes by providing slope of the chassis in the cross-slope direction without guessing. Stable Blade complements operator blade control input, allowing the operator to finish grade easier, quicker and with less effort.
Available as part of the Cat attachment ready option (ARO) for easy scalability to GRADE with 3D control systems, Slope Assist saves time by helping the operator to more easily achieve the desired blade mainfall slope (fore/aft) and cross slope (left/right) by automatically maintaining the operator's established blade grade angles. The dozers' Power Pitch option enables the operator to control blade pitch (fore/aft) remotely from the operator's compartment to optimize blade pitch for blade loading, optimizing machine productivity by up to 6 percent.
Two undercarriage configurations - standard and LGP (low ground contact pressure) - will continue to be offered for the Next Gen small dozers. The XL designation will no longer be used with the new series. The LGP 30-in (762-mm) track will be offered for the D1 and D3 models to improve traction and flotation in exceedingly marginal underground conditions.
New power unit
The new D1, D2 and D3 Next Gen small dozers are powered by the fuel-efficient Cat C3.6 diesel engine, which now meets more stringent EU Stage V as well as U.S. EPA Tier 4 Final emission standards. For markets with less strict emissions standards, a Tier 3 equivalent engine is available with the same net power ratings as the Stage V/Tier 4 Final engines.
While offering the same net power ratings as their previous series counterpart models, these new Next Gen dozers deliver up to 10 percent improved fuel economy. Eco Mode, available in forward/reverse or reverse only options, improves fuel economy by automatically reducing engine speed when not required. When load changes necessitate higher engine RPM, Eco Mode automatically allows the engine to deliver maximum speed and power until the load decreases.
As one of the latest models in the R2-Series excavator lineup, the Bobcat® E88 delivers durability, performance and quality for more productivity. Technically speaking, it's a compact machine, but it brings big performance with its redesigned engine and optimized lift performance, plus undercarriage and counterweight improvements. All these enhancements make this excavator one of the highest-performing models in its size class. With impressive over-the-side lift capacity, you can dig with greater confidence over the side of the machine. Put it to the test against similar models from other manufacturers. You'll see that the E88 can outwork the competition.
