Develon (formerly Doosan Infracore) raises the bar for wheeled excavators with the introduction of the new Series K.
Building upon the solid technical foundation of its predecessors, the updates focus on tangible performance improvements, operational efficiency, and a significantly enhanced operator experience. This article delves into the main innovations characterizing this evolved generation.
Highlights of the Updates
Enhanced and Optimized Engine
- New power units: Latest-generation Deutz engines (TCD 3.6 L4 for WEX-7K | TCD 4.1 L4 for DX210W-7K)
- Compliance with Stage V/Tier 4 Final standards
- +9% torque: Superior responsiveness under heavy loads
- Improved efficiency: Integrated optimizations reduce fuel consumption
iDCS Hydraulic System (Intelligent Dual Control System)
- Independent flow control: Intelligent oil management to actuators (boom, arm, bucket, wheels)
- Smooth and combined movements: Eliminates interference between functions
- Dynamic adaptation: Automatic adjustment of power/flow based on load
Dynamic Stability System (DSS)
- Active stabilization in motion: Real-time pressure adjustment of stabilizers
- +70% speed on rough terrains: Enhanced safety without manual interventions
- Optimized productivity: Reduced setup times between operations
“NexGen” Cab
- Advanced ergonomics: Redesigned layout, premium materials, 360° visibility
- Command station: Suspended seat (mechanical/air-suspended optional), adjustable steering wheel, and orientable hydraulic console
- 10″ multifunction display: Central hub for telemetry, diagnostics, DSS adjustments
- Enhanced air conditioning: Thermal comfort in all conditions
Simplified Maintenance
- Improved accessibility: Reorganized inspection points to reduce downtime
- Extended intervals: Less frequent replacement of filters (oil, fuel, air)
Develon DX210W-7K Wheeled Excavator
The new Develon DX210W-7K stands at the pinnacle of the 21-ton wheeled excavator category. Designed to maximize performance and productivity on construction sites, this model offers an ideal combination of power, precision, and operational comfort, making it the perfect solution for urban, infrastructure, and road works.
Powerful and Efficient Performance
Equipped with the proven Develon DL06V Stage V engine, the DX210W-7K delivers 141 kW (189 hp) at 1900 rpm, with a maximum torque of 593 lbf·ft at 1400 rpm. Thanks to the Smart Power Control (SPC) system, the machine automatically adjusts speed and hydraulic torque to optimize fuel consumption and reduce environmental impact while maintaining high performance.
Advanced Mobility and Hydraulics
With two main pumps delivering 236 l/min each, the excavator ensures rapid and precise hydraulic response. Wheeled mobility is guaranteed by a variable travel speed up to 34 km/h and a traction force of 12,000 kg. The minimum turning radius of 7.2 meters allows agile maneuvers even in confined urban spaces.
