Hitachi ZX240-3 Hydraulic Excavator: Detailed Introduction

The Hitachi ZX240-3 is a versatile 24-tonne class hydraulic excavator that belongs to Hitachi Construction Machinery's Zaxis-3 series. Renowned for its exceptional balance of power, fuel efficiency, and operator comfort, the ZX240-3 is designed to excel in a wide range of heavy-duty applications, including earthmoving, trenching, demolition, quarrying, and general construction. It integrates advanced hydraulic technology, a powerful yet clean engine, and a robust structural design, making it a reliable workhorse for contractors worldwide.

1. Engine and Emissions

At the heart of the ZX240-3 lies a turbocharged and after-cooled Isuzu AH-4HK1X diesel engine. This 4-cylinder, 5.193-litre powerplant delivers a net output of 132 kW (177 hp) at 2,000 rpm. The engine is compliant with EPA Tier 3 / EU Stage IIIA emission regulations, achieved through cooled exhaust gas recirculation (EGR) and a common-rail high-pressure fuel injection system. The combination ensures optimal combustion, reduced particulate matter and NOx, and excellent fuel economy without compromising performance.

2. HIOS III Hydraulic System

The excavator features Hitachi's advanced HIOS III (Human & Intelligent Operation System III) hydraulic technology. This system precisely matches engine speed and hydraulic pump output to the actual workload, significantly reducing fuel consumption during light-duty or idling operations. Key components include:

Two variable-displacement axial piston pumps providing high flow rates for fast cycle times.
A sophisticated control valve that delivers smooth, proportional movement to the boom, arm, and bucket.
Flow regeneration circuits on the arm and boom that reuse hydraulic fluid to speed up movements without demanding extra power from the pumps.The result is a highly responsive, fuel-efficient, and easy-to-control machine that reduces operator fatigue.

3. Operating Performance and Specifications

The ZX240-3 combines powerful digging forces with stable lifting capabilities. Its performance parameters are tailored for productivity:

Operating Weight: Ranges from 24,200 kg to 25,200 kg depending on configuration (standard counterweight, boom, arm, and undercarriage).
Bucket Capacity (heaped): 0.80 – 1.20 m³ (compatible with Hitachi’s pin-grabber quick coupler system).
Max Digging Depth: 6,700 – 7,030 mm (varies with arm length).
Max Reach Along Ground: 9,970 – 10,280 mm.
Bucket Digging Force (ISO): Up to 158 kN (16.1 tf).
Arm Digging Force (ISO): Up to 114 kN (11.6 tf) with the standard 2.96 m arm.
Swing Speed: 11.3 rpm, with a swing torque of 64.1 kN·m.
Drawbar Pull: 207 kN, ensuring excellent tractive effort on slopes and in soft ground.
Travel Speeds: Low: 3.4 km/h / High: 5.5 km/h.

The machine is built with a reinforced boom, arm, and track frame using thick, high-tensile-strength steel plates. Welded joints are designed for high durability, and the cast-steel swing frame absorbs shocks from rough terrain.

4. Operator Environment – The CRES II Cab

The ZX240-3 features the CRES II (Centre-Recognized Excavator System II) cab, which sets industry standards for comfort and safety:

Spacious Interior: A wide, flat floor with ample legroom and a high-quality, adjustable suspension seat (optionally air-suspended) with integral heat.
Excellent Visibility: A large glass area with a tinted front window that slides upward into the roof panel, a right-side window with no center pillar for unobstructed side view, and a standard overhead skylight for enhanced upward visibility.
Climate Control: Automatic air conditioning with excellent air distribution and defroster function.
Low Noise & Vibration: The cab is mounted on viscous isolation dampers, and sound-absorbing insulation reduces internal noise to a remarkably low 70 dB(A). Vibrations are minimized to reduce operator strain during long shifts.
Ergonomic Controls: Short-pilot control levers with proportional auxiliary controls, a multi-function LCD monitor displaying fuel consumption, maintenance intervals, and machine health diagnostics. A rearview camera is integrated into the monitor as standard on many markets.

5. Durability and Maintenance

Hitachi designed the ZX240-3 for easy daily maintenance and long service life:

Accessibility: Wide-opening right-hand side doors and a tilt-up engine hood provide ground-level access to the engine, hydraulic pumps, filters, and coolers. The radiator, oil cooler, and intercooler are arranged in parallel for easy cleaning.
Extended Service Intervals: Engine oil and filter changes are required every 500 hours, and hydraulic oil every 5,000 hours.
Filter Layout: Grouped fuel main and pre-filters, engine oil filter, and pilot filter are located in a dedicated pump compartment for quick replacement.
Centralized Greasing: Grease fittings for the swing bearing and front attachments are conveniently grouped to reduce greasing time.
Advanced Diagnostics: The machine is equipped with an on-board self-diagnosis system and can be connected to Hitachi’s E-Service remote monitoring (satellite-based or GPRS) for real-time machine tracking, operational data, and fault alerts, helping fleet managers maximize uptime.

6. Undercarriage Options

The ZX240-3 is available with various undercarriage configurations to suit different working conditions:

Standard LC (Long Crawler): With 600 mm triple-grouser shoes, provides stability for heavy digging.
Narrow Undercarriage: Reduced width for transport in tight spaces.
Road Liner: Rubber pad inserts for operation on paved surfaces.

The undercarriage features fully welded track frames with X-pattern structural beams, sealed and lubricated track chains, and heavy-duty idlers and rollers designed to withstand high lateral loads.

7. Versatility and Attachments

The ZX240-3’s hydraulic system can be equipped with auxiliary piping, allowing it to power a wide array of attachments beyond the standard bucket:

Hydraulic breakers (e.g., NPK, Furukawa) for demolition.
Pulverizers and crushers.
Tilt buckets and grading buckets.
Vibro rippers.
Auger drives.
Grapples for sorting and material handling.

A quick-coupler option further increases versatility by allowing rapid tool changes without leaving the cab. An automatic power boost function provides an additional 8% increase in hydraulic pressure for up to 8 seconds when the going gets tough, ideal for breakout force during heavy digging or breaker operation.

In summary, the Hitachi ZX240-3 is a well-rounded 24-tonne excavator that delivers high productivity, outstanding fuel efficiency, and exceptional operator comfort. Its durable construction, advanced hydraulic system, and easy maintenance features make it a popular choice for contractors seeking reliable performance in demanding job-site conditions.
