GET MORE FROM YOUR MACHINE You’re at the heart of Hitachi Construction Machinery's design for its latest range of excavators. To continuously improve on previous generation machines, we’ve focused on enhancing your profit in business. We have made cost reduction for our customers our top priority and, in doing so, have achieved reduced fuel consumption. The cab has been redesigned to improve the operator's working environment and controllability, with production also expected to improve. An engine that already has a proven track record of high reliability has been adopted, and we have placed further work in it to make it even more robust. Remote failure diagnosis, monitoring, and OTA (Over The Air - controller rewriting) are also supported to reduce downtime. MORE PRODUCTION LOWER FUEL CONSUMPTION The HIOS-V new Hydraulic system has achieved both increased productivity and reduced fuel consumption in each mode. The ZAXIS performance contributes to increase the returns to the customer. HIOS-V Hydraulic system The hydraulic system developed was based on the concept of a hydraulic system that fits in-line with a sense of human operation. Efficient hydraulic control achieves smoother and more speedy movement of front attachments. Fine-tuned hydraulic pump control according to work load reduces fuel consumption and supports cost reductions. Reduced oil pressure loss A new valve has been adopted to reduce hydraulic loss and further improve hydraulic efficiency. Contributing to low fuel consumption operation High power engine Rated power has been increased from the conventional ZX470-5G engine contributing to greater work volume. Increased workload
