ZOOMLION has achieved a significant milestone in smart mining with the large-scale deployment of nearly 100 autonomous mining trucks across multiple sites in China. The unmanned trucks, operating in Xinjiang and Inner Mongolia, have demonstrated reliable performance in extreme conditions including temperatures as low as -30°C and strong winds.     The autonomous haulage system integrates ZOOMLION's hybrid and electric mining trucks with a full-stack intelligent control platform. The system enables autonomous navigation, obstacle avoidance, path planning, and coordinated loading with excavators.   The performance results are compelling. At a large open-pit mine in Xinjiang, 40 autonomous trucks have been operating 18 hours daily in continuous service since early 2026, with equipment availability exceeding 95%. The unmanned operation has significantly improved safety by reducing on-site personnel, cut labor costs through reduced manpower requirements, and increased overall transport efficiency by approximately 10%.     The company has also unveiled its Mine Smart Supervision Platform 2.0 and Mine Operation & Diagnosis Platform 2.0, which stream real-time equipment data to the cloud for monitoring, fault prediction and maintenance tracking.  

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.
