74 E&MJ; • MARCH 2014 E Q U I P M E N T G A L L E R Y www.e-mj.com Caterpillar says its new D10T2 dozer builds on the proven D10T with refinements to its power train, automated controls and struc- tures. The result: high productivity, reliable operation with long-lived structures, and enhanced access for service technicians and operators. The D10T 2, according to Cat, uses the latest load-sensing hydraulics technology, combined with Cat advanced engine controls, to maximize the amount of material moved per unit of fuel burned. Improved filtration protects the fuel sys- tem, hydraulic system, and power train oil system to help ensure high reliability and minimal machine downtime. Refined large structures, such as redesigned track roller frames, deliver longer service before rebuilds. Improved access and egress fea- tures enhance safety and productivity of technicians and operators, and optional powered access systems and platforms enable configuring the D10T 2 for the site. The D10T 2 is available with two varia- tions of the Cat C27 engine: one is U.S. EPA Tier 4 Final certified, and the other is equivalent to U.S. EPA Tier 2 standards. Both engine configurations produce 600 net hp in forward gears and 722 hp in reverse gears (447/538 kW). The engine controller automatically adjusts power out- put based on the direction of travel. With the new system, the D10T 2 has about 20% more power in reverse compared to its predecessor model. The result is faster cycle times and greater productivity in cer- tain applications. Enhanced AutoShift (EAS)—a new stan- dard feature—improves fuel efficiency and productivity by automatically selecting the optimal gear and engine speed combination based on power train load and desired ground speed. EAS functionality combined with the increased power in reverse en- hances productivity when backing up slopes. Another new feature, Adaptive Load Select, enhances Autocarry by automati- cally adjusting blade load based on operat- ing conditions, such as underfoot condi- tions and track wear. Similarly, the new Automatic Ripper Control monitors speed and automatically adjusts engine speed and ripper depth to minimize track slip. A new blade control system automatically guides the blade to the desired design con- tours, and is integrated with Autocarry to sense and automatically control the load of the blade for improved performance and efficient blade loading applications. www.cat.com Wheel Loader Built for Mine Duty Case Construction Equipment's new 1221F loader is the newest and largest model in the company's F Series wheel loader line. Designed with an 11.9-liter, Tier 4 Interim-certified engine that delivers up to 355 hp (265 kW), the 1221F is built for heavy earthmoving and loading applica- tions such as those encountered in mining operations. Enhancements to the engine and transmission at maximum travel speed allow for increases in productivity of at least 18% and fuel efficiency of at least 8%, according to the company. The 1221F has an operating weight of 66,800 lb (30,300 kg) and comes with a range of buckets from 6.3 to 7.8 yd 3 . With a 6.8-yd 3 bucket, breakout force is 55,730 lb. The machine is available in standard Z- bar and extended-reach (XR) configura- tions. Additional highlights include: • Four programmable power modes to save fuel and increase available power. A dual-mode shutdown feature helps maxi- mize fuel economy and monitor vital engine components. • Standard four-speed transmission with manual kick-down for maximum trac- tion, as well as superior bucket pene- tration. Also available is a five-speed transmission with a lockup torque con- verter, open-differential axles and ad- vanced system programming for addi- tional fuel savings. • Open rear-axle and locking front-axle for outstanding traction.
