Nepalese buyers prioritize durability, adaptability, and cost-effectiveness when sourcing gabion machines from China. Core requirements include:

1. Robustness & Reliability:

   • Machines must withstand Nepal’s challenging terrain, high humidity, dust, and variable power supply.

   • Heavy-duty steel frames, high-quality gearboxes (e.g., SEW, Nord), and premium bearings (e.g., SKF, NSK) are essential.

   • Proven track record of low breakdown rates is critical due to limited local technical support.

2. Power Compatibility & Stability:

   • Voltage/Frequency: Must operate flawlessly on 415V, 3-phase, 50Hz power (Nepal standard).

   • Voltage Fluctuation Tolerance: Built-in tolerance for ±10-15% voltage swings common in Nepal. Integrated voltage stabilizers or recommendations for external ones are highly valued.

   • Altitude Performance: Certified operation up to 1,500-2,000 meters ASL (covering Kathmandu & major project sites) without power derating.

3. Technical Specifications:

   • Machine Type: Double-Twist Hexagonal Weaving Machines are overwhelmingly preferred over welded mesh types due to superior flexibility, strength, and suitability for erosion control.

   • Mesh Sizes: Capability to produce common Nepali sizes: 60x80mm, 80x100mm, 100x120mm (easily changeable via molds).

   • Wire Diameter: Must handle 2.0mm to 3.0mm PVC/Galfan coated wires (2.2mm & 2.7mm most common).

   • Mesh Width: Standard 2m or 4m width capability (4m reduces on-site splicing).

   • Production Speed: Minimum 25-35 m²/hour for 80x100mm/2.2mm wire under Nepali conditions.

   • Wire Spools: Large-capacity spool holders (≥Φ500mm) to minimize downtime.

4. Control & Ease of Use:

   • PLC + HMI Touchscreen: Essential for parameter setting, speed control, fault diagnosis, and production counting. English interface mandatory.

   • Precise Length Counting: Integrated encoder/measuring wheel for automatic cut-off (±1% accuracy).

   • Break Wire Detection: Automatic停机 with audible/visual alarm.

   • Tension Control: Mechanical or simple automated systems preferred over complex (maintenance-heavy) servo systems.

   • Double Take-Up System: Critical for continuous production – one reel fills while the other is replaced.

5. After-Sales Support (Non-Negotiable):

   • Comprehensive English Documentation: Detailed manuals (operation, maintenance, parts list, electrical diagrams).

   • Training: On-site commissioning & thorough training for operators/maintenance staff.

   • Warranty: Minimum 12 months on the whole machine, longer on core components.

   • Spare Parts: Readily available common spares (bearings, gears, moulds, sensors) with a recommended initial stocklist. Commitment to long-term (10+ years) parts supply.

   • Technical Support: Responsive remote support (email/WhatsApp/video call) + clear escalation path for complex issues. Preference for suppliers with agents/service partners in India/Nepal.

6. Adaptation to Local Conditions:

   • Dust Protection: Enhanced sealing on electrical cabinets (IP54+) and critical moving parts.

   • Corrosion Resistance: Critical components treated for rust prevention.

   • Simplicity & Maintainability: Design prioritizing ease of maintenance with standard tools. Avoids overly complex electronics where robust mechanical solutions suffice.
