All wiring harnesses are industrial-grade, designed for vibration resistance and environmental protection, adhering to IP (Ingress Protection) ratings suitable for harsh outdoor conditions.

6. Final Assembly and Cab Installation: All sub-assemblies come together. The drilling mast, feed system, dust collection unit, and tracks/wheels are mounted. The ergonomic operator cabin, complete with climate control, safety glass, and intuitive controls, is then installed.

7. Testing and Quality Assurance:

• Functional Testing: Every Photovoltaic Type Open-Air Drilling Car undergoes rigorous functional testing. This includes testing all movements (tramming, mast raising/lowering), drilling functions (rotation, feed, percussion if applicable), hydraulic pressures, electrical systems, and emergency stops.
• Performance Testing: The drilling car is tested under simulated load conditions to verify drilling speed, penetration rate, and energy consumption/generation. The photovoltaic charging system and battery discharge rates are closely monitored.
• Safety Compliance: Adherence to international safety standards (e.g., CE, ISO 12100, MSHA guidelines where applicable) is verified. This includes structural integrity, electrical safety, and noise levels.
• Surface Treatment: After final assembly and testing, the machine undergoes thorough cleaning, priming, and multiple layers of industrial-grade paint for corrosion protection, essential for an open-air drilling car operating in harsh environments. This significantly enhances the product's resistance to rust and extends its aesthetic life.
