Used CAT349D2L Excavator

The CAT349D2L excavator offers powerful power, high digging efficiency, comfortable operation, and easy maintenance, among other advantages. Excellent Power Performance Powerful Engine: Equipped with a Cat C13 ACERT engine, it boasts a rated power of 301.0 kW (according to ISO14396) and a net power of 289.0 kW (according to SAE J1349/ISO9249). It delivers stable and powerful power at speeds between 1800 and 2100 rpm, easily handling high-intensity operations such as mining and large-scale infrastructure construction. Excellent Fuel Economy: Utilizing turbocharging technology and a high-pressure common rail injection system, it achieves a more complete mixing of fuel and air, resulting in higher combustion efficiency. Compared to some conventional engines, fuel consumption can be reduced by approximately 10%-15% under the same operating conditions. Environmentally Friendly: Equipped with advanced ACERT technology, it meets stringent environmental standards, including U.S. EPA Tier III, EU Stage IIIA, Japan 2006 (Tier III) equivalent, and China Stage III, reducing particulate emissions by over 50%. High Operating Efficiency High Digging Force: Bucket digging force reaches 267kN, and arm digging force reaches 201kN, making it easy to dig even in hard rock and soil. Combined with a swing speed of 8.7rpm, it allows for quick adjustments to the working direction, improving operating efficiency. Advanced Hydraulic System: A boom regeneration circuit, first featured on the 349D2L, is managed by the machine’s ECM, improving cycle time and fuel efficiency. The hydraulic system features automatic priority for boom raise and swing operations, automatically assigning priority based on operator input. Comfortable and Convenient Operation Comfortable Cab Environment: The pressurized cab offers positive-pressure filtered ventilation with a choice of fresh or recirculated air. All glass, except the rear window, is frameless, and a large polycarbonate skylight provides excellent overhead visibility. Effortless Operation: Pilot-operated position-shifting joysticks allow the operator to operate the machine while resting their arms on the armrests. Vertical stroke is longer than horizontal, reducing fatigue. The joysticks incorporate integrated pushbuttons and slide switches for controlling all implement and swing functions. Rugged and Durable Construction Structural Design: The mainframe features a box-section design connected to large-diameter pipes at the boom foot for increased rigidity and strength. The track frame’s top has a steep angle to help prevent mud and debris buildup, and the box-section design enhances rigidity and impact resistance. Quality Components: The boom features a large cross-section and internal baffles. The arm is constructed of high-strength steel. Its large box-section design, internal baffles, and attached bottom guard ensure years of service in demanding applications. The track links are assembled and sealed with grease to reduce internal bushing wear and extend service life. Low Maintenance Costs Easy Maintenance: Extended service intervals, advanced filtration technology, easy filter changes, and a user-friendly electronic diagnostic system make servicing quick and easy, effectively reducing maintenance costs. High-Performance Filters: An improved filtration system ensures engine reliability even with poor fuel quality, reducing the number of filters and lowering maintenance costs.
