The XE400DK excavator utilizes a low-speed, high-torque, high-pressure common rail engine, delivering robust power while significantly reducing fuel consumption. Additionally, the XE400DK is equipped with an electronic control system that provides integrated management of engine speed and hydraulic pump input power, along with fault monitoring and diagnostic capabilities.
I. More energy-saving and environmental friendly
1. By adopting imported electronic fuel injection engine, the machine has stronger power and higher fuel economy.
2. High pressure common rail system realizes optimum fuel injection control and effectively improves combustion efficiency.
3. With optimized engine power curves and low-speed and large-torque output, the fuel consumption is greatly reduced while providing strong power, which satisfies dynamic balance and economy of power output and fuel consumption in heavy-duty mode.
II. More reliable and durable

1. Mining and Heavy-Duty Operations
The XE400DK is a reliable partner for mining operations. Its reinforced working equipment, extended and widened heavy-duty undercarriage system, and dual-gripping-tooth track pads are specifically engineered for heavy loads, effortlessly handling ore excavation, earthmoving loading, and crushing tasks. Its formidable digging force (bucket digging force: 310 kN) and efficient performance significantly boost mining productivity.
2. Infrastructure Construction
This excavator model is widely applicable for large-scale earthmoving projects such as highway and bridge construction, municipal works (e.g., urban foundation excavation), and more. Its robust power and stable performance effectively handle diverse road construction materials, completing tasks like earth excavation, trench laying, and site leveling.
3. Agricultural Water Conservancy Projects
In agricultural water conservancy initiatives, the XE400DK can excavate ditches, dig ponds, and undertake farmland reclamation. Its excellent fuel efficiency helps reduce long-term operational costs, making it a reliable choice for enhancing agricultural infrastructure.
4. Port Construction and Other Applications
The XE400DK also serves in port construction and other earthmoving scenarios. Its robust structure and stable performance meet the demanding requirements of port operations.
Before operation, thoroughly inspect engine oil, hydraulic fluid levels, and reinforced undercarriage structure. After starting, idle for 3-5 minutes to warm up. During heavy-duty operations, maintain smooth movements and avoid abrupt turns or stops. In mining conditions, pay special attention to equipment stability and regularly inspect the dual-stage air filtration system. Thoroughly clean the equipment after operation, focusing on checking wear on the working attachments and tracks. Perform regular maintenance on the hydraulic system and fuel filter, and lubricate all hinge points. Always observe the surrounding environment, maintain safe operating distances, and pay particular attention to equipment stability during heavy loads.
1. IS SENSOR DATA (E.G., PRESSURE, TEMPERATURE) SIGNIFICANTLY INACCURATE OR FLUCTUATING?
First, inspect the sensor connector for loose connections, oxidation, or water ingress. Only then consider sensor failure. Finally, assess whether the controller interface is faulty.
2. FUSES BLOWING FREQUENTLY?
Never replace with a higher-amp fuse! This indicates a short circuit or overload fault in the circuit. Systematically inspect all electrical components (e.g., sensors, solenoid valves, lights) and wiring harnesses along the circuit according to the schematic diagram.
3. ENGINE STARTS POORLY, ESPECIALLY IN COLD WEATHER?
① Insufficient battery charge or weak starter motor.
② Incorrect diesel grade (excessively high pour point).
③ Faulty preheating system (glow plugs/grille heater).
④ Air in the fuel line or clogged diesel filter.
4. WHEN THE EQUIPMENT IS PARKED, DO YOU NOTICE GEAR OIL DRIPPING ONTO THE GROUND?
Damage to the oil seal or breather of the final drive (travel motor reducer).
5. DOES THE FRAME FEEL TWISTED DURING STRAIGHT TRAVEL?
(For articulated equipment) Excessive wear clearance in the articulation pins and bearings.
6. ARE BUCKET TEETH ROOTS WEARING EXCESSIVELY FAST?
Failure of the pins and retaining rings connecting the teeth to the bucket causes loosening, leading to vibration and accelerated wear during operation.
