The power for these machines is derived from the reliable Yanmar diesel engines equipped with proven turbocharging technology. The model 4TNV98CT engine delivers 67.6 horsepower with 292.9 Nm of torque achieving faster cycle times and stronger digging forces compared to their predecessor models. They also feature a versatile power/economy work mode that adapts the machine’s performance to the specific task at hand. In power mode, the engine operates at higher speeds to deliver additional horsepower, when necessary, whereas the economy mode optimises fuel efficiency by reducing engine speed during regular operations.

Furthermore, both machines are equipped with a built-in auto-idle system, which automatically reduces the engine to an idling speed if all control levers remain in a neutral position for more than 4 seconds. Once the levers are reactivated, the engine quickly returns to the previously chosen speed. This feature not only helps in reducing noise and exhaust emissions but also plays a pivotal role in energy conservation and cost savings for operations.

Compact excavators are commonly used as tool carriers with a wide range of attachments that increase job-site versatility.  The -7 series models are factory fitted with Quick Coupler piping as well as Low and High flow attachment piping, conveniently controlled with electric switches on the pilot control levers.   For added convenience, there is an available attachment replacement support system that streamlines the process of switching between different work tools. This system allows for the adjustment of attachment flow settings directly from the low-reflective collar 8-inch LCD monitor, enabling operators to designate and save up to 12 unique settings.

The ZAXIS-7 series has been engineered to maximise operator productivity and comfort. Cab space has been significantly enlarged compared to previous generation. Designing cabs with panoramic visibility helps create a safe and comfortable working environment.

To further enhance safety and comfort, Hitachi goes the extra mile by incorporating the Aerial Angle peripheral vision camera system, which grants operators an extensive 270-degree bird’s-eye view of the machine’s surroundings on the upsized low reflect 8 inch monitor. The inclusion of long-lasting LED ambient work lights on the left, right & rear of the machine, as opposed to halogen lights, ensures a prolonged operational lifespan and improved visibility in challenging conditions. These work lights even remain illuminated for 30 seconds after the machine is powered off, enhancing safety when disembarking from the cab during night-time operations. The addition of the wide view wiper, featuring a parallel link mechanism, increasing the window wiping area by 183% compared to the previous model.

Hitachi excavators are renowned for their exceptional durability, and the ZAXIS-7 series introduces improvements to crucial components, including the arm and boom. The enhancements involve minimising pinhole tolerances in the boom and arm, effectively reducing lateral movement or wobbling. Furthermore, the side plate thickness of the blade has been augmented to enhance its resilience against external impacts.
