• Compact Design: The 190W is compact in size, making it suitable for operating in confined spaces or urban environments where space is limited.
  
• Powerful Engine: Equipped with a high-performance engine, the 190W provides the necessary power to handle demanding tasks while maintaining fuel efficiency.
  

The 190W Zaxis is particularly effective in applications that require both digging power and the ability to move quickly between sites, such as roadworks, urban construction projects, and infrastructure maintenance.
Key Features of the Hitachi 190W Zaxis
The Hitachi 190W Zaxis comes with several advanced features designed to enhance its performance, durability, and versatility. These features are what make it stand out among other wheeled excavators in its class.
1. Advanced Hydraulic System
One of the standout features of the Hitachi 190W Zaxis is its advanced hydraulic system, which improves the overall productivity of the machine. The system allows for smooth, precise control when performing tasks such as digging, lifting, and handling materials. The hydraulic system is also designed to be fuel-efficient, reducing the overall operating cost while delivering optimal performance.

• Flow Sharing Technology: This feature allows for simultaneous operation of multiple hydraulic functions without compromising performance. For example, the boom can be raised while the bucket is being rotated, allowing for faster cycle times.
  
• Hydraulic Regeneration Circuit: This improves energy efficiency by reusing energy from the downward movement of the boom to assist with lifting, thus reducing fuel consumption.
  

2. High Maneuverability and Speed
The wheeled design of the Hitachi 190W Zaxis provides exceptional maneuverability on paved surfaces, making it faster than traditional tracked excavators. This is especially beneficial for applications that require the machine to travel long distances between job sites or between specific points on a site.

• Top Speed: The Hitachi 190W can travel up to 35 km/h (22 mph), significantly reducing transport time compared to tracked models.
  
• Maneuverability: Its ability to navigate tight spaces and turn on a dime is particularly useful in urban construction environments, where space is limited and the machine must be able to make sharp turns and move around obstacles.
  

3. Comfortable Operator Cabin
The operator’s cabin on the Hitachi 190W Zaxis is designed for comfort and ease of use. It features a spacious layout with excellent visibility, ergonomic controls, and a fully adjustable seat. The cabin also provides reduced noise and vibration levels, helping to improve operator comfort during long shifts.

• Climate Control: The cabin is equipped with a heating and air conditioning system, ensuring that operators can work comfortably in varying weather conditions.
  
• User-Friendly Controls: The controls are intuitive, reducing operator fatigue and enhancing productivity. The layout ensures that all functions are easily accessible, and the joystick controls provide precise movements.
  

4. Enhanced Stability
Despite being wheeled, the Hitachi 190W Zaxis is equipped with a stability system designed to ensure optimal performance even during heavy-duty tasks. It features a wide stance and an advanced chassis design that prevents tipping, even when working on uneven ground or lifting heavy loads.

• Hydraulic Stabilizers: These stabilizers ensure that the excavator remains steady during operations, particularly when digging or lifting materials. This feature allows for safe operation even in challenging conditions.
  
• Load-Sensing Technology: The load-sensing system continuously adjusts the hydraulic pressure based on the load being carried, ensuring that the machine performs optimally under all conditions.
