Construction machinery in Southeast Asia, the Middle East, Africa and other tropical areas operates continuously under high temperature, bringing heavy load to the heat dissipation system. Poor heat dissipation causes soaring hydraulic oil temperature, insufficient power and operation jamming. Long-term high-temperature operation leads to wear and aging of precision internal parts and increases failure risks. Equipment adapted to high-temperature conditions is optimized in heat dissipation structure and dust filter configuration to ensure smooth air circulation and rapid heat dissipation. In daily use, regularly clean dust and sundries on radiators and filters to avoid blockage; avoid overloaded operation in midday high temperature. Targeted protection and maintenance relieve high-temperature wear, stabilize equipment performance and adapt to long-term operation in tropical regions.
