Caterpillar added six machines to the companys D Series product line Tuesday, launching three new compact track loaders and three new multi terrain loaders as replacements for B3, C and C2 Series models. Cat also updated two compact track loader models.
Ranging in rated operating capacity from 2,800 pounds to 4,650 pounds at 50 percent of tipping load, the rubber-track loaders include the mid-size models 257D multi terrain loader and 259D compact track loader, the larger frame 277D and 287D multi terrain loaders and the 279D and 289D compact track loaders.
With a Tier 4 Final electronically-controlled 3.3-liter engine that delivers 74 horsepower, these new machines offer 8 percent more torque and 6 percent better fuel economy than the models they replace.
Meanwhile, Cat updated the existing 299D and 299D XHP, the two largest of the D Series compact track loaders. Both machines feature a 3.8-liter engine that delivers 98 gross horsepower. Available since 2012, the 299D and 299D XHP feature Cats completely new cab and a new lift arm design.
The new Cab-One operator station, a sealed and pressurized cab design found on all eight machines, offers one-piece modular construction instead of a standard two-piece design.
Caterpillar says the cab improves sealing, enabling the HVAC system to supply 20 percent more airflow and increasing heating and cooling rates by 60 percent for a cleaner, more comfortable working environment. New features include a high-back heated air suspension seat with recline and lumbar adjustments; independent arm bar and joystick control adjustments and a standard control monitor with a single code security feature.
Other new features include an electronic dial-type throttle that allows for precise rpm settings for additional control and a new throttle-smoothing feature that monitors accelerator pedal movement on rough terrain. Lift arms feature a tubular design for strength combined with a narrow profile, and an electrically actuated work tool coupler is available.
