Since its release in January 2008, the Hitachi EX5600-6, as well as the company’s ultra-large hydralic excavators — the EX8000-6, EX2500-6, EX3600-6, and EX1900-6 — have been highly valued by global mining customers, including major mining companies, for their production and high availability, based on reliability. In response to requests by mining owners and operators to increase the production capability without significantly increasing footprint, Hitachi is proud to introduce the new EX5600-6. The EX5600-6 has a number of improvements, while retaining its many proven features. It is heavier than its predecessor, has more engine horsepower and the BE-backhoe version has increased bucket capacity. Estimated productivity increases are 17% for the short-reach BH backhoe and 12% for  the loader version. Loading time per truck has been lessened as well. The bucket capacity for the EX5600-6 backhoe version has been increased from 29 m3 (38 cu yd) to 34 m3 (44.5 cu yd). The reach of the backhoe front attachment has been shortened and the engine output boosted to achieve higher productivity with a cycle time equivalent to the -5 version. The loader bucket capacity has been increased as well, from 27 m3 (35.5 cu  yd) to 29 m3 (38 cu  yd). The EX5600-6 is offered in both backhoe and loader shovel configurations. The exclusive auto-leveling crowd mechanism increases job effiency with one-lever control. Hitachi’s computer-aided engine-pump control coaxes optimum efficiency from the engine and hydraulic pumps. This innovative system senses load demand and controls the engine and pump output for maximum operating efficiency.
