Caterpillar has refined the design of its skid steer and compact track load- ers and designated the line B-Series 3. Models include 216B3, 226B3, 236B3, 242B3 and 252B3 skid steers and 247B3 and 257B3 compact track loaders. A redesigned dead-engine lower valve provides an easier-to-use, more-positive means of lowering the lift arms if the machine should run out of fuel or stall with the arms raised. A new lever-action handle acts di- rectly on the hydraulic relief valve. A new single ECM has been moved from the lower frame to the back of the cab and provides easier access to electrical service points as well as simplified wiring and a reduction in the number of connections. Cat added power to the 242B3 skid steer and 257B3 compact track loader with a 71-horsepower engine, which in- creases net power by 25 percent, and a hydraulic system with about 40 percent more standard flow, at 22 gpm.
The vertical-lift S740 skid steer loader is a new model for Bobcat, equipped with a Tier 4-Final engine that, at 74 horsepower, does not require a DPF or SCR technology.
The vertical-lift 272D2 skid steer, 297D2 multiterrain, and 299D2 compact track loaders (and the XHP versions) have been upgraded to include the Advanced Display as standard equipment and enhanced airflow debris control.
The 173-horsepower Cat MH3027 material handler is the fourth and smallest in the series of wheeled material handlers that Caterpillar is introducing in the greater-than-25-metric-ton size class.
The Cat 336F L XE Hybrid hydraulic excavator captures and reuses energy, delivering an estimated fuel savings of up to 20 percent compared with its standard 336 counterpart.
