The CAT313D2GC excavator offers powerful power, comfortable operation, and easy maintenance, as detailed below: Excellent Power and Performance Engine: Equipped with a 70.2kW Cat C4.4 ACERT engine, it meets U.S. EPA Tier 3, EU Stage IIIA equivalent emission standards, and China Off-Highway Stage III emission standards. The engine utilizes a proven mechanical governor and low-pressure fuel injection system for high fuel efficiency and durability. Energy-Efficient Hydraulic System: Designed for high efficiency and performance, the hydraulic system features auxiliary hydraulics and electrical lines routed to the boom frame for easy installation. The boom and arm energy regeneration system conserves energy during boom lowering and arm retracting operations, improving efficiency and reducing operating costs. Diverse Operating Modes: Three operating modes are available: Intelligent, Fuel-Efficient, and Powerful. Power can be selected based on specific tasks to meet diverse working conditions and achieve a balance between fuel efficiency and productivity. Excellent Digging Capability: With greater digging force and a faster bucket dump, the excellent digging and swing drive contribute to increased swing torque and smoothness, resulting in exceptional productivity and making it easy to handle a variety of digging operations. Comfortable and Convenient Operation User-Friendly Cab Design: The ergonomically designed operator station is spacious, quiet, and comfortable, with all switches conveniently located on the right-hand console. The monitor features a full-color liquid crystal display (LCD), adjustable to minimize sunlight glare, and displays information in Chinese and multiple languages. Effortless Operation: The pilot-operated joystick controls are designed for low-effort operation, allowing the operator to maintain a natural wrist and arm posture, reducing fatigue and improving work efficiency. Comprehensive Features: The wide seat accommodates operators of all sizes, and standard automatic climate control ensures a comfortable temperature throughout the entire operation. Convenient features include a radio, headphone jack, and a USB port for connecting and charging devices. Low Maintenance Costs Easy Maintenance: The left-side service door provides easy access to key components such as the engine radiator and oil cooler. A radiator-mounted water reservoir and drain cock simplify maintenance. Most routine maintenance can be performed at ground level, reducing time spent on daily tasks. Long Maintenance Intervals: Extended and better-synchronized service intervals extend the life of hydraulic and air filters, and the pilot and case drain filters are eliminated, reducing maintenance frequency and costs.
