Used CAT306D Excavators For Sale

The CAT 306D is Caterpillar’s flagship model in the 2.5-3 ton mini excavator market, renowned for its exceptional performance, reliability, and versatility. Its strengths can be summarized in the following key areas: 1. Superior Performance and Efficiency Powerful and Efficient Powertrain: Equipped with a genuine Caterpillar C1.1 turbocharged diesel engine, renowned for its low fuel consumption and high reliability. Compliant with stringent emission regulations (such as EU Stage IIIA/US Tier 4 Interim), it eliminates the need for complex aftertreatment systems (such as a DPF), reducing points of failure and maintenance costs. Sufficient power reserve ensures stable output, even in high altitudes or harsh working conditions, ensuring operational efficiency. Advanced Hydraulic System: Utilizing a load-sensing hydraulic system, this system precisely distributes hydraulic flow and pressure according to actual demand, minimizing energy loss and providing smoother operation and more precise control. The dual-pump system allows for smoother and more coordinated compound movements (such as boom raise + swing + bucket dig), significantly improving cycle speed and efficiency. The optional multi-mode operating system (such as SP Mode – Power Priority and E Mode – Fuel-Efficient) allows the operator to select the most appropriate power output for different operating conditions, achieving the optimal balance between efficiency and fuel consumption. II. Unparalleled Reliability and Durability Sturdy Structural Design: Major structural components (such as the boom, chassis, and upper frame) are constructed of reinforced steel and a box-type design. Optimized through CAE (Computer-Aided Engineering) analysis, this design ensures uniform stress distribution, strong torsion and impact resistance, and a long service life. The sturdy chassis and reinforced X-frame ensure the stability and durability of the entire machine on rugged terrain. Top-notch component quality: Most core components (engine, hydraulic pump, valves, motor, etc.) are independently developed and manufactured by Caterpillar, ensuring highly compatible operation and ensuring overall machine interoperability and long-term reliability. High-quality materials are also used in details such as pipes and oil seals to minimize the risk of leakage. Convenient Maintenance: Centralized maintenance points: Grease fittings, oil filter, fuel filter, pilot filter, and more are easily accessible, allowing most routine maintenance to be performed from ground level, saving time and labor. Extremely long maintenance intervals: Hydraulic and engine oil change intervals are significantly longer than the industry average, reducing maintenance costs and downtime over the long term. Wide-opening maintenance door: The engine hood opens fully, providing ample maintenance space for easy access. III. Excellent Operator Experience and Comfort First-class Driving Environment: The certified ROPS/FOPS cab provides safety and excellent visibility, with minimal pillars to minimize blind spots. The low-noise design ensures minimal interior noise, ensuring fatigue-free operation even during extended periods. The suspension seat automatically adjusts to the operator’s weight, and the integrated pilot control handle in the armrest ensures effortless and comfortable operation. Precise and Convenient Control: The hydraulic pilot control provides extremely light operating force, responsive and linear movement, and precise micro-control, enabling precise and accurate work (such as pipe laying and interior decoration). The ergonomic design of the travel pedal and handle ensures intuitive operation.
