Operators can select one of three hydraulic power modes from the monitor. Speed mode gives maximum speed and power for heavy work. Balance mode optimizes performance and fuel effi ciency for general work. Effi ciency mode provides maximum control and effi ciency for light work. John Deere and Hitachi David Young, product marketing manager, excava- tors, North and South America with John Deere and Hitachi, calls attention to the three-pump system on the 245G LC and ZX245USLC-6. The third pump is assigned to swing function. "Swing cannibalizes the hydraulics on two-pump systems and can become the limiting factor in performance, especially if the machine is on a grade or slope." Both are 25-metric ton, reduced-tailswing machines; 30-ton models will launch in April. Information integration and sharing are making great strides, according to Andrew Kahler, product marketing manager, John Deere WorkSight. JDLink (Deere) and ZXLink (Hitachi) run on a 4G LTE cel- lular network. The current system has more memory and more power and has both Bluetooth and Wi-Fi to enable communication with multiple devices and platforms. Because there has been no standard com- munication protocol for telematics data, customers have had to gather information from machines by brand and then manually integrate the results, a prac- tice known as "portal hopping." Data are now sent via an application program interface (API) to data integrators so information from a mixed fl eet can be viewed in a single portal. Information management and maintenance of infor- mation hardware are generally within the capabilities of most customers, says Kahler. Machine-specifi c in- formation can also be shared with dealers to help co- ordinate PM and repair. Data from equipment running across North America are aggregated and analyzed at Deere's facility in Dubuque, Iowa, to look for trends and allow the OEM to be proactive in resolving issues and improving machine performance. Kobelco Kobelco is working with Trimble to develop tech- nologies for use with excavators. One result is the choice of Grade Assist (an indicate system) and 2D and 3D machine control. That much is fairly standard in the industry. What makes the Kobelco/Trimble de- sign unique is the use of gyroscopic sensors instead of in-cylinder sensors and surface-mounted position sensors. These gyroscopic sensors are similar to those used in aircraft and in the vehicle stability control machine matters | continued Key technologies on the Hyundai HX380L include an intel- ligent 8-inch touchscreen monitor and automotive-style haptic controller with tactile feedback in the form of vibra- tions and pulses. The 40-metric-ton machine has three power modes – Power, Standard and Economy – and runs on a Cummins QSL9 engine rated at 344 net horsepower. The largest Hitachi reduced-tailswing excavator is the ZX245USLC-6. Five years of ZXLink Ultimate comes standard and provides online access to machine location, health, utilization and other vital information. Powered by an Isuzu engine rated at 159 horsepower, the ZX245USLC-6 features rotary dial access to monitor selections and ergonomic, short-throw pilot lever controls.
