Engine Type: Diesel (standard for this class of vehicle) Performance Horsepower Range: Typically in the 800-1200 HP range for trucks of this payload capacity. Torque Range: High torque output crucial for hauling heavy loads in demanding conditions. Fuel System Fuel Type: Diesel Fuel Injection System: Likely advanced common rail or unit injector system for efficiency and emissions. 🔧 Transmission Standard Transmission Type: Heavy-duty automatic transmission, likely an Allison or ZF heavy-duty off-highway transmission. Optional Optional Transmissions: Not specified, but heavy-duty trucks often have limited transmission options. Features Gear Selection: Multiple forward gears and reverse, designed for extreme load conditions and variable terrain. Cooling: Robust transmission cooling system is essential. 📐 Dimensions Exterior Length: Estimated 9-12 meters (approx. 30-40 feet) for a truck of this class. Width: Estimated 5-6 meters (approx. 16-20 feet) including mirrors and bodywork. Height: Estimated 4.5-5.5 meters (approx. 15-18 feet) in transport configuration. Cargo Payload Capacity: Designed for payloads in the range of 200-400 tons (approx. 400,000 - 800,000 lbs). Weights Operating Weight: Typically 150-250+ tons (300,000-500,000+ lbs). Gross Vehicle Weight Rating Gvwr: Significantly higher than operating weight, reflecting maximum laden capacity. 🛡️ Safety Features Ratings Crash Test Ratings: N/A (Heavy construction equipment typically does not undergo standard automotive crash testing protocols. Safety focuses on operator protection and machine stability). Active Features Braking System: Advanced hydraulic or air-over-hydraulic braking systems, often with retarder functions. Stability Control: Designed for high stability with robust suspension and chassis. Passive Features Operator Cab: Reinforced, pressurized operator cab with enhanced visibility, ergonomics, and potentially FOPS/ROPS (Falling Object/Roll-Over Protective Structures). Visibility: Multiple mirrors, wide-view windows, and auxiliary lighting for all-around visibility. 💡 Technology Features Infotainment Infotainment System: Minimal to none. Focus is on operational controls and diagnostics, not typical passenger car infotainment. Driver Assistance Diagnostic Systems: Onboard diagnostics for engine, transmission, and hydraulic systems are standard for fault detection and maintenance. Payload Monitoring: Advanced models may include payload monitoring systems to optimize loading and prevent overloading. Connectivity Telematics: May include telematics for fleet management, remote monitoring of operational hours, fuel consumption, and diagnostic codes. 🔧 Maintenance Service Intervals Engine Oil Change: Refer to manual for specific intervals based on operating hours and conditions. Typically hundreds of hours. Hydraulic Fluid Change: Critical for system longevity; intervals depend heavily on operating hours and contamination levels. Typically 1000-2000 hours. Filter Replacement: Regular replacement of engine oil, fuel, hydraulic, and air filters is crucial. Intervals specified in manual. Fluid Specifications Engine Oil: High-quality heavy-duty diesel engine oil, e.g., API CK-4 or equivalent, with appropriate viscosity grade (e.g., 15W-40). Hydraulic Fluid: ISO VG 46 or similar high-quality hydraulic oil, often with anti-wear and extreme pressure additives. Transmission Fluid: Specific heavy-duty...
