Product Uses
1. Mining and Heavy-Duty Operations
The XE520DK is the ideal choice for medium-sized mines and large quarries. Its China III-compliant mining-specific engine, reinforced working equipment, L-shaped extended heavy-duty chassis, and reinforced axle shafts with dual-side fixed design make it particularly suited for rock extraction, ore excavation, and heavy-duty material handling. Its exceptional bucket digging force (330 kN) and large-capacity bucket significantly enhance extraction and loading efficiency.
2. Large-Scale Infrastructure Construction
This excavator model is widely applicable for major earthmoving projects such as highway and bridge construction, municipal works (e.g., urban foundation excavation), and similar large-scale earth and rock operations. Its powerful performance and stable operation effectively handle diverse road construction materials, completing tasks including earth excavation, trench laying, and site leveling.
3. Sand and Gravel Aggregate Production and Processing
In aggregate production, the XE520DK excels at raw material extraction, feeding into crushing lines, and loading finished products. Its high efficiency and energy-saving characteristics help reduce operational costs in large-scale production, making it a reliable choice for aggregate enterprises.
4. Other Applicable Scenarios
The XE520DK is also suitable for port and terminal construction, as well as excavating ditches and ponds in large-scale agricultural water conservancy projects. Its versatility meets diverse construction demands.
Product Operate Guide
Before operation, check engine oil, hydraulic fluid, and coolant levels, with particular attention to the heavy-duty chassis structure. After starting, idle for 3-5 minutes to warm up. During operation, maintain smooth movements and avoid abrupt turns or stops during heavy-load tasks. Select appropriate operating modes to enhance efficiency and regularly inspect the slewing system's condition. Thoroughly clean the equipment after use, paying special attention to bucket and working attachment wear. Perform monthly maintenance on the hydraulic system and lubricate all hinge points. Continuously monitor the surrounding environment, maintain safe operating distances, and pay particular attention to equipment stability during heavy-load operations.
FAQ
1. HOW IS YOUR PRICE COMPARED WITH MANUFACTURERS/FACTORIES?
We work as the leading dealers of various leading China construction machinery manufacturers/ factories, and are constantly treated with best dealership price. From numerous comparison and feedbacks from clients, our price is more competitive than the price from manufacturers/factories.
2. HOW IS YOUR DELIVERY TIME?
In general circumstance, we can have an immediate delivery of regular machines for our clients within 7 days, because we have a variety of resources to check machines in stock, locally and nation widely, and to receive machines in timely manner. But for manufacturers/factories, it will take more than 30 days to produce the ordered machine.
3. WHICH PAYMENT TERMS CAN YOU ACCEPT?
Normally we can work on T/T term or L/ term, sometime DP term.
1)On T/T term, 30% down payment is required in advance, and 70% balance shall be settled before shipment, or against the copy of original B/L for long-term cooperating client.
2)On L/C term, a 100% irrevocable L/ C without "soft clauses"from an international recognized bank can be accepted. Please seek the advice from the individual sales manager whom you work with.
4. ABNORMAL VIBRATION IN HYDRAULIC HOSES?
Internal hose lining may have flaked off and caused blockage, or loose hose clamps may induce resonance.
5. INSUFFICIENT FLOW AFTER REPLACING THE HYDRAULIC PUMP?
Check suction lines for blockages, collapsed sections, or air leaks due to poor sealing.
6. NORMAL OPERATION WHEN COLD, BUT SLOW RESPONSE AFTER WARMING UP?
Internal leakage in the hydraulic system increases with rising temperature. Focus on inspecting the clearance between the pump, valves, and motor.
