Engineering the Urban Workhorse
The construction landscape is evolving. Modern job sites are becoming increasingly confined, particularly in urban environments where every inch of space matters. The TYPHON NAGA 4.0 Mini Excavator was conceptualized not just as a piece of machinery, but as a direct response to these challenges. It represents a paradigm shift in compact excavation, proving that a smaller footprint does not require a sacrifice in raw power or hydraulic capability. By integrating a 4-ton chassis with a zero-tail swing architecture, the NAGA 4.0 delivers a solution that bridges the gap between nimble micro-excavators and heavy-duty industrial earthmovers.
01. The Yanmar Powerhouse
At the core of the NAGA 4.0 lies the Yanmar 3TNV88F Diesel Engine, a legendary power plant chosen specifically for its balance of torque and reliability. This 3-cylinder, direct-injection engine generates 18.2 kW (24.4 hp) at 2200 rpm. Unlike generic alternatives, the Yanmar platform ensures compliance with strict EPA Tier 4 Final and EU Stage V emission standards without the complex maintenance requirements of Diesel Exhaust Fluid (DEF) systems.
The engine's 1.642L displacement provides the low-end grunt necessary for heavy lifting, while its advanced cooling system and 6.7L oil capacity ensure thermal stability during prolonged operation. For the owner-operator, this translates to reduced downtime, easier sourcing of parts, and an engine lifespan that significantly outlasts competitor models in the same price bracket.
02. Hydraulic Superiority
Power is nothing without control. The hydraulic system of the NAGA 4.0 is driven by a high-efficiency plunger pump delivering a flow rate of 96.8 L/min. This massive hydraulic flow is what gives the machine its "unstoppable" character. It translates directly into a bucket digging force of 30.4 kN and an arm crowding force of 18.2 kN.
Whether you are trenching through compacted clay, breaking concrete, or lifting heavy stone, the hydraulic system maintains consistent pressure. Furthermore, the inclusion of a Three-Way Stop Valve allows for seamless integration of auxiliary attachments. Operators can switch between buckets, augers, and hydraulic thumbs without complex re-plumbing, making this machine a versatile multi-tool for any job site.
03. Zero-Tail Swing Architecture
The defining feature of the NAGA 4.0 is its Zero-Tail Swing design. In traditional excavators, the counterweight extends beyond the tracks during rotation, creating a collision hazard in tight spaces. The NAGA 4.0 keeps its entire upper structure within the width of the tracks during a full 360-degree rotation.
With a tail swing radius of just 860mm, operators can work confidently alongside walls, fences, and busy roadways without fear of rear-swing impact. Combined with a Boom Swing capability of 55 degrees to both the left and right, the machine can perform offset digging parallel to foundations—a critical task that standard fixed-boom machines cannot achieve.
04. Operator-Centric Design
Productivity is directly linked to operator comfort. The NAGA 4.0 features a spacious, enclosed cabin equipped with both Air Conditioning and Heating, allowing for year-round operation regardless of weather conditions. The front glass window opens for ventilation and communication with ground crews.
Technologically, the machine is ahead of its class. A 7-inch Smart Touchscreen Dashboard provides real-time diagnostics, including engine health, hydraulic status, and maintenance reminders. Perhaps most importantly, the machine offers ISO/SAE Selectable Controls. This feature allows operators to toggle between "Excavator Pattern" (ISO) and "Backhoe Pattern" (SAE) instantly, ensuring that any operator can jump in and work safely and efficiently without a learning curve.
