Interview with Designers of the Mid-Size Excavators
The "Made by HITACHI" global quality standard, produced at the "Mother Design Factory" in Japan.
ZAXIS70
Boosted Productivity
Efficient hydraulic system and new intercooled turbocharger diesel engine were developed for ZAXIS-3.
These advanced technologies are at work to yield bigger output with higher fuel efficiency.
More production, less fuel consumption
Increased Production
A combination of the hydraulic system (HIOS*II) and new intercooled turbocharger engine allows the efficient use of hydraulic pressure to increase speeds of actuators and boost production with higher fuel efficiency. The productivity is increased 5 % in comparison to previous model ZAXIS-1.
*Human & Intelligent Operation System
E-mode
The E mode and P mode can be selected to suit job needs. The E mode can save fuel consumption by up to 12 % compared to the previous model's P mode, while yielding similar production.
Increase in Swing Torque, Traction Force and Travel Speed
Swing torque and traction force are increased significantly.
-Swing torque 11 % UP
-Traction force 4 % UP
-Travel speed 6 % UP
Sophisticated Travel Control; At climbing or steering, when the machine needs more traction force, the engine speed automatically increases which makes the machine faster.
Efficient hydraulic control
Hydraulic System
The Hydraulic System elicits more user satisfaction than other models due to its greater operator comfort and ease of operability. During arm roll-in operations, the hydraulics of 3 pumps are merged, allowing for quick leveling operations. Depending on the operations, usage of the 3 pumps are automatically switched, offering excellent operability. It supports stability and combined operability, such as speed balance and land clearing.
Speed Sensing Control
A speed sensing system is used for hydraulic horsepower control. The hydraulic pump delivery flow, which varies with changes in engine RPM according to the load, is controlled. This means efficient use of engine horsepower, and also contributes to a reduction in fuel consumption.
Development concept of new engine
Intercooled Turbocharger Engine
The new intercooled turbocharger engine is developed and built to comply with the rigorous Emission Regulations enforced in 2008 in U.S and EU. This new engine contributes to environmental preservation. At the same time it realizes high durability and low fuel consumption by adapting the latest advanced engine technology.
Cooled EGR* System
Exhaust gas is partially mixed with intake air to lower combustion temperature for reducing NOx and fuel consumption. Whatfs more, the EGR cooler cools down exhaust gas to increase air concentration for complete combustion, reducing PM** (diesel plume).
*Exhaust Gas Recirculation
**Particulate Matter
Improved crowding performance
Reshaped Blade (Optional)
The blade is reshaped for crowding without loss.
