Extreme Cold Operation Issues

In Arctic Circle and Nordic port regions, extreme low temperatures (down to -40°C) pose severe challenges to equipment operation and personnel efficiency:

1. Equipment Performance Degradation

• ​Lubricant Viscosity Surge: Hydraulic oil and gear oil thicken, causing hydraulic system blockages and reduced transmission efficiency

  .
• ​Material Brittleness: Metal components become brittle, and brake fluid freezing risks brake failure.

2. Energy Loss and Efficiency Reduction

• ​Cold-Start Fuel Waste: Incomplete combustion during cold starts increases energy consumption by 30%.
• ​Prolonged Logistics Delays: Traditional preheating methods take hours, extending port operation cycles (e.g., Russian Arctic ports reported 40% delays).

3. Harsh Working Conditions

• ​Operator Safety Risks: Cabin temperatures below -20°C reduce reaction speed by 15-20% and increase frostbite risks.
• ​Maintenance Challenges: Equipment repair times double or triple compared to temperate zones.

​Targeted Solutions: Full-Scene Intelligent Preheating System

To address these challenges, we developed a ​comprehensive preheating system covering five critical modules:

1. ​Hydraulic Oil Tank Preheating
   Prevents oil thickening and valve jams.
   

2. ​Gearbox Preheating
   Ensures optimal gear lubrication and reduces cold-start wear.
   

3. ​Brake Fluid Tank Preheating
   Eliminates brake fluid freezing hazards.
   

4. ​Antifreeze Preheating
   Accelerates engine warm-up for faster startup.
   

5. ​Cab Air Heating
   Raises cabin temperature to 20°C within 10 minutes for operator comfort.

   
   

This system, activated via power supply, enhances operational efficiency by 50% and has been successfully deployed in multiple high-latitude port projects
