KOMATSU Machinery Manufacturing (Shandong) Co., Ltd. officially commenced operations at its new facility in the Jining High-tech Zone on June 5, 2026. With a total investment of approximately RMB 10.6 billion and covering an area of 2,000 mu (about 133 hectares), the new plant represents a major upgrade to KOMATSU's production footprint in China.   The facility will serve as the sole production base in China for KOMATSU's full range of hydraulic excavators from 5T to 60T models and HD1500 heavy-duty mining trucks. It is positioned to undertake component production tasks accounting for 70% of KOMATSU's global manufacturing capacity. The technology platform for hydraulic excavators will be upgraded from PC-8 to PC-11, representing a leap across two generations.     The new plant features a fully digitalized manufacturing system with IoT technology, automated production lines, and AI-powered quality inspection systems. It has also introduced 11 supporting suppliers to establish an integrated "host + components" industrial park—a unique model for KOMATSU globally. This strategic move clearly signals KOMATSU's commitment to positioning its China operations as a global supply hub serving worldwide markets.  

Summer heat does more than make operators sweat. It turns hydraulic oil into a silent threat to your excavator's most expensive components.   When ambient temperatures rise, hydraulic oil temperature climbs with them. As oil heats up, its viscosity drops. The oil film that protects pump pistons, valve spools, and cylinder seals becomes thinner and weaker. Metal components no longer glide on a protective layer—they rub, score, and wear against each other.   Industry data shows that every 10°C increase in hydraulic oil temperature above the recommended operating range can cut pump life in half. Seals harden and shrink at high temperatures, leading to internal and external leaks. Contamination becomes more difficult to control as degraded oil breaks down and forms varnish on valve surfaces.     Manufacturer maintenance guidelines from XCMG and SANY emphasize several essential summer hydraulic care practices: weekly oil level checks prevent pump cavitation, seasonal viscosity upgrades—ISO 68 for consistently hot climates, ISO 46 for moderate conditions—maintain proper film strength, and regular filter changes keep circulating oil clean and contaminant-free. Clean oil coolers and radiators are also critical, as debris buildup reduces heat dissipation by up to 30%.   For fleet managers and operators, the message is simple: hot oil wears machines faster. A few minutes of preventive maintenance each week keeps hydraulic oil cool, components protected, and machines running through the hottest months.
