LIUGONG excavators have completed months of continuous operation at a high-altitude mining site in Kyrgyzstan's Batken region, demonstrating reliable performance in one of Central Asia's most demanding environments. The site sits at approximately 4,000 meters above sea level, where steep terrain, frozen ground, and freezing winds present severe challenges to heavy equipment.   The machines have operated without major downtime, while LIUGONG's local service team maintained uninterrupted support throughout the deployment. Local operators and project managers cited the equipment's robust performance in the extreme conditions, according to industry reports.     The Kyrgyzstan deployment reflects LIUGONG's broader overseas momentum. The company's overseas revenue reached RMB 10.455 billion in the first half of 2026, up 22.66% year-on-year, with sales in Africa and the Asia-Pacific region both growing more than 30%. LIUGONG has also established a local subsidiary in Kyrgyzstan and deployed service personnel to support equipment operations at high-altitude sites, including the China-Kyrgyzstan-Uzbekistan railway project.   The high-altitude mining application underscores the growing presence of Chinese construction equipment in Central Asia's mining and infrastructure sectors, where equipment reliability under extreme conditions is a decisive factor for project operators.  

Winter mornings bring a familiar frustration to construction sites: the excavator turns over but won't fire. The battery is charged, the starter works, but the engine refuses to catch. In most cases, the problem isn't electrical—it's the fuel in the tank.   Diesel fuel contains paraffin wax that crystallizes as temperatures drop. When diesel cools below its cloud point, wax crystals begin to form. Below the pour point, the fuel thickens enough to stop flowing through filters and fuel lines entirely. For 0# diesel, the pour point sits around 0°C, and gelling can begin at temperatures as mild as 5°C.   Manufacturer winter maintenance guidelines from SHANTUI and industry practice recommend selecting diesel grades based on local minimum temperatures, not average conditions. The pour point of the fuel should sit 4-6°C below the lowest expected temperature. In southern regions with mild winters, -10# diesel provides adequate protection. In northern China and severe cold zones, -20# or -35# grades are required.     Fuel system care extends beyond grade selection. Filling the tank at the end of each shift reduces the air space inside, which limits condensation on the tank's inner walls. Water accumulation in the fuel system accelerates filter clogging and corrosion. Operators should also check water separators daily and drain any accumulated moisture before it reaches the injection system.   A final consideration is fuel filter replacement. Cold fuel is thicker and passes through filters more slowly. A partially clogged filter that performs adequately in summer can restrict flow enough to prevent starting in winter. Replacing fuel filters before the cold season begins is cheap insurance against a no-start morning.   For fleet managers, winter diesel management is a planning exercise. Match the fuel grade to the forecast, fill tanks at shift end, and replace filters before the first freeze. None of these steps takes more than a few minutes, but together they keep machines starting on the coldest mornings.
