Machine Introduction
The Fiat Hitachi EX215 is a mid-sized hydraulic excavator produced during the joint venture between Fiat and Hitachi, beginning in 1986. Manufactured in San Mauro Torinese, Italy, the EX215 blends Italian and Japanese engineering principles for a reliable, versatile machine suited for diverse construction and earthmoving applications.
Engine and Powertrain
- Powered by an Iveco 6-cylinder, 4-stroke turbocharged diesel engine with direct injection, delivering a rated power of about 135 to 145 horsepower (99 to 107 kW).
- Engine displacement is approximately 5.86 liters with a bore and stroke measuring 104 mm by 115 mm.
- Equipped with a 24V, 4 kW starter motor and a 28V, 55A alternator to support robust electrical needs.
- Features a cross-sensing summation system, which optimizes hydraulic efficiency and fuel savings.
- Main pumps include bent-axis plunger-type, variable displacement pumps with pressure sensors controlling pump and valve operations, ensuring smooth and powerful hydraulic performance.
- Oil cooler assembly combines radiator and oil cooler functions with capacities of approximately 6.7 liters and 5.1 liters, respectively, allowing effective temperature management.
- Hydraulic oil tank capacity near 145 liters supports extended operation.
- Overall operating weight ranges from approximately 19,400 to 21,400 kilograms depending on configuration such as monoblock or long carriage (LC) versions.
- Machine length extends roughly 9.5 meters, with widths between 2.48 and 3.29 meters dependent on model variant.
- Tail swing radius of about 915 to 1,030 millimeters facilitates operation in confined spaces.
- Track gauge and length around 2,455 mm and 2,870 mm respectively, providing strong stability and traction.
- Excavation depth typically reaches up to around 5 meters, suitable for medium-depth digging tasks.
- Bucket capacities vary, often around 0.7 cubic meters, enabling versatile material handling.
- Work modes incorporate general purpose, grading, precision, and attachment modes, selectable to maximize efficiency across different tasks.
- Controls managed through an advanced microcomputer built-in main controller that integrates engine speed, pump pressure, and valve operation for optimal machine response.
- The machine includes safety-relay and diode-protected electrical circuits to ensure reliability.
- Hydraulic systems incorporate regenerative valves and auto-idle controls to improve fuel economy and reduce operator fatigue.
- Electronic controls allow operators to switch power modes for different job requirements easily.
- Fiat Hitachi was a prominent joint venture combining Fiat’s manufacturing experience and Hitachi’s advanced excavator technology, producing a range of construction machinery in Europe.
- The joint venture ended around 2001, succeeded by Fiat Kobelco and later New Holland Construction, marking an evolution in product branding and innovation.
- Turbocharged Diesel: Engine with forced air induction for enhanced power output.
- Cross-Sensing Summation: Hydraulic system optimizing pump flow for better fuel efficiency.
- Variable Displacement Pump: Pump capable of adjusting fluid volume to demand.
- Tail Swing Radius: Rear clearance needed when the upper structure rotates.
- Auto-Idle Control: Engine management system reducing RPM when idle to save fuel.
The Fiat Hitachi EX215 excavator represents a sophisticated integration of engineering excellence, providing reliable hydraulic power, efficient operation, and adaptable performance for construction professionals. Its solid build, advanced hydraulics, and intelligent controls ensure effective productivity in varied site conditions, while its heritage underscores the global collaboration behind its design and manufacture.
