AGGREGATES MANAGER April 2015 16 Clean sheet design excavators Hyundai Heavy Industries will present the first six models in a new range of excavators, including the HX220 L, HX260 L, HX300 L, HX330 L, HX380 L, and HX520 L. Engineers used a clean sheet design to develop the Tier 4 Final machines, which use a combined solution of EGR and SCR technologies. All but the HX520 units are equipped with Cummins engines; the top- sized model has a Scania engine. The new cab has improved front glass and is 10 percent larger than prior models. A larger, 8-inch monitor is easier to read and offers more functions. At the same time, fuel consumption has been reduced by 3 to 6 percent. All six units will be available in North America, Hyundai says.

The unit is said to be the most com- pact heavy-duty mobile screen in the Warrior range, making it easy to transport. It is designed for operators who need versatility, maneuverability, and transportability. The screen is also said to be highly versatile with a simple conversion from three-way split mode to two-way split mode, which can be completed in minutes. The unit features an 8- by 4-foot, high-amplitude, two-bearing screen box capable of 6 G of acceleration. Powerscreen | www.powerscreen.com Versatile hydraulic drifter Montabert will launch the HDC95 multi-purpose drifter, which is available in three models, including the HC95 LQ designed for surface drilling operations in the quarry mar- ket. In addition, the HC95 LA can replace another drifter already installed on a drilling machine to optimize perfor- mance. The multi-purpose unit was designed to allow it to be swapped for another with minimum intervention. The third model is the HC95 M, which is designed for underground drilling operations. It includes hammering with hydraulic reverse percussion as a standard feature. Montabert | www.montabert.com Aggregates-specific excavator Liebherr will unveil the R 946, its first crawler excavator to meet Tier 4 Final emission standards. The R 950 SME (Super Mass Excavation), devel- oped using the R 9446 base specifically for quarry applications, will also debut. The R 946 has an operating weight of approximately 44 tons (U.S.) and a 272-horsepower engine. The six-cylinder Liebherr engine inte- grates a new Tier 4 Final exhaust gas treatment system, which features a SCR system using urea injection to post-treat exhaust gases. Liebherr says the unit has a robust steel structure to ensure reliability in tough appli- cations. Through a smart system, which uses sensors placed in strategic locations around the excavator, the machine can optimize the operation of the engine and hydraulic system to maximize fuel usage.
