July/August 2018 | Utility Contractor 41 Hitachi ZX345USLC-6 Ultrashort Excavator Hitachi's ultrashort excavator lineup in North America continues to grow with the intro- duction of its most powerful reduced-tail-swing excavator – the ZX345USLC-6. The new ZX- 345USLC-6 will offer contractors increased reach, dig forces, bucket capacity and lift capacity, while simultaneously making it possible to work in tight, confined spaces. With generous legroom, the ZX345USLC-6 cab features daylong convenience and comfort and is the only full-size cab on a reduced tail swing machine in the industry. Built with the same toughness as Hitachi's large mining excavators, the 30-metric-ton ZX345USLC-6 delivers efficiency, reli- ability and durability. The ZX345USLC-6 features an exclusive three-pump hydraulic system that provides multifunction performance and the fast cycle times. Hitachiconstruction.com John Deere Updates 210G LC Excavator, 130G - 470G LC Models John Deere added grade guidance technology to the 210G LC excavator and made nu- merous other customer-inspired updates to improve productivity, uptime and lower daily operating costs on the 13 to 47 ton models. The grade guidance system provides operators with information on the bucket's location with respect to a 2D reference or 3D design sur- face and is ideal for digging trenches for pipe, shaping ditches or slopes, or digging structure foundations. The system was developed in cooperation with Topcon. The integrated grade guidance displays the elevation and position of the bucket cutting edge with respect to a target plane (2D) or design surface (3D). Factory integration and calibration ensure the machine arrives on the jobsite ready to work. JohnDeere.com Komatsu Introduces New PC390LCi-11 Komatsu America Corp. recently introduced the new PC390LCi-11 hydraulic excavator, the first 3D semi-automatic excavator available with the nimbleness and speed of the popular 36-ton weight class machines and stability of much larger machines. Intelligent Machine Control features a unique sensor package, including stroke sensing hydraulic cylinders, an IMU sensor, and GNSS antennas. The ma- chine utilizes 3D design data loaded into the machine's monitor to accurately dis- play machine position relative to target grade. When the bucket reaches the target surface, automation kicks in to limit over excavation. The PC390LCi-11 excavator, whether rented, leased or purchased, is covered by the Komatsu CARE compli- mentary maintenance program for the first three years or 2000 hours, whichever comes first.

To improve this time-consuming process, Vactor Manufacturing introduced the Vactor RDB 1015 rapid deployment boom as an option for the company's 2100 Series combination sewer cleaners, which include the Vactor 2100i and 2100 Plus trucks. Designed in Vactor's research and development facility and proven in the field, the patent-pending boom telescopes 10 ft out and extends the debris hose an additional 15 ft down for faster cleaning.
