Boosted Productivity
Short-tail-swing makes possible efficient operations in various confined worksites.
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.
Applicable in Various Job Sites
Short 1 290 mm rear-end swing radius promises efficient operations in confined spaces.
*In figure, machines are expressed by model codes for presentation.
The photo shows an excavator with a 1.62 m arm installed.
- Rear-end swing radius is shorter than of ZX70-3.
- Short 1 810 mm minimum swing radius .
Stability Exceeds Standard Model
Stability is increased by using the exclusive US weighted counterweight.
- Stability: 17 % increase
(vs. ZX70-3)
More production, less fuel consumption
Increased Production
A combination of the hydraulic system 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.
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 and Traction Force
Swing torque and traction force are increased significantly.
-Swing torque 9% UP
-Traction force 8% UP
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. What's more, the EGR cooler cools down exhaust gas to increase air concentration for complete combustion, reducing PM** (diesel plume).

Improved crowding performance
Reshaped Blade (Optional)
The blade is reshaped for crowding without loss.
