• Integrated with Hitachi’s advanced engine control system – The throttle dial works in conjunction with the machine’s Engine Control Dial system, which is part of Hitachi’s sophisticated electronic control architecture. This system includes features such as:

  • Engine Protection Control – Prevents engine damage by automatically adjusting operation parameters

  • ECO/PWR Mode Switch Control – Allows operators to select between fuel-saving ECO mode and maximum-power PWR mode

  • Auto-Idle Control – Automatically reduces engine speed during idle periods to save fuel

  • One-Touch Idle Control – Enables instant idle speed reduction with a single touch

• Designed for the Zaxis-7 wheeled excavator range – The ZX180W-7 is part of Hitachi’s Zaxis-7 wheeled excavator series, featuring impressive fuel economy and reduced running costs. The throttle dial is precision-matched to this platform, ensuring optimal engine performance and fuel efficiency. The new Zaxis-7 models offer up to 7% reduction in fuel consumption compared to previous generations.

• High-quality Japanese engineering – Manufactured in Japan to Hitachi’s stringent quality standards, ensuring durability and reliable performance in the toughest operating conditions.

• Ergonomic design for operator comfort – The throttle dial is positioned for easy, intuitive operation within the spacious Zaxis-7 cab, which offers the ultimate in comfort and quality with low noise levels and reduced vibration.

• Direct plug-and-play replacement – This throttle dial assembly is a direct replacement for the original Hitachi unit. Connects to the existing wiring harness with standard connectors – no modifications, no adapters.

• Pre-shipment visual verification – Before packing, we send you detailed high‑resolution photographs of the actual unit (connectors, part number markings, overall condition). You approve shipment – we never ship blind. Video inspection is also available upon request.

• Fast delivery – 5–7 working days lead time from our Guangzhou warehouse. Flexible shipping options including DHL, TNT, UPS, FedEx, and sea freight.

2. Technical Specifications

3. Applications

The Hitachi ZX180W-7 Throttle Dial Assembly (YA00049351) is a critical operator control component for 18‑ton class wheeled excavators used across a wide range of versatile job sites:

• Urban construction & utilities – Sidewalk repairs, water and gas line trenching, fibre-optic cable installation, and small-scale demolition in tight urban spaces. The throttle dial’s precise speed control allows operators to match engine power to delicate work near existing structures, while the one-touch idle feature reduces fuel consumption during frequent stops.

• Road & bridge maintenance – Shoulder repairs, guardrail replacement, drainage cleaning, and slope stabilisation. The wheeled design allows the ZX180W-7 to travel on public roads under its own power, and the throttle dial ensures smooth, responsive engine control for both road travel and worksite operations. The new Zaxis-7 models offer up to 7% reduction in fuel consumption compared to previous generations, significantly lowering operating costs.

• Residential & commercial development – Foundation digging, basement excavation, retaining walls, grading, and site preparation. The ECO/PWR mode switch allows operators to select fuel-saving ECO mode for lighter work or maximum-power PWR mode for heavy digging, optimising fuel efficiency and productivity.

• Quarrying & aggregates – Loading trucks, stockpile management, and material handling in abrasive dust conditions. The throttle dial’s robust construction withstands the harsh quarry environment, ensuring reliable performance shift after shift.

• Equipment rental fleet – 18‑ton wheeled excavators are frequently rented machines due to their versatility in both road travel and worksite digging. A genuine new throttle dial assembly provides predictable performance and eliminates the risk of control system failure – avoiding costly mid‑rental breakdowns and customer complaints.

• Forestry & land clearing – Steep slopes, fallen timber, and uneven terrain place variable loads on the machine. The throttle dial allows operators to quickly adjust engine speed to match changing conditions, maintaining consistent productivity and fuel efficiency.
