Boosted Productivity
New hydraulic system HIOS II and new DOHC 4-valve 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 DOHC 4-valve 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
New E-mode
The new E mode, H/P mode and P mode can be selected to suit job needs. The new E mode can save fuel consumption by up to 8% compared to the previous model's P mode, while yielding similar production.
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 - HIOS II
HIOS II Hydraulic System
The HIOS II hydraulic system elicits more user satisfaction than other models on the market due to its greater operator comfort and ease of operability. Our ZAXIS-3 model not only adopts this technology but also improves it, adding several enhancements over previous models. It offers a balance between the operability of the front attachment arm and its manoeuvring speed, resulting in an improved capacity to handle combined operations with maximum stability during excavation.
Development concept of new engine
DOHC* 4-Valve Engine
The new DOHC 4-valve diesel 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.
*Double Overhead Camshaft
Common Rail Type Fuel Injection System
Electronic control common rail type fuel injection system drives an integrated fuel pump at an ultrahigh pressure to distribute fuel to each injector per cylinder through a common rail. This enables optimum combustion to generate big horsepower, and reduce PM* (diesel plume) and fuel consumption.
*Particulate Matter
Cooled EGR* System
The cooled EGR system lets part of exhaust gasses mix with intake air for re-combustion to reduce oxygen concentration in the air in the combustion chamber. This design lowers combustion temperature in the cylinder, reducing fuel consumption and NOx while yielding more horsepower.
*Exhaust Gas Recirculation
