Good Condition Used CAT307 Excavator

The CAT307 excavator, a benchmark model for small and medium-sized hydraulic excavators, demonstrates outstanding advantages in core areas such as operational efficiency, operating cost control, and adaptability. It is particularly well-suited for applications such as municipal engineering, small-scale infrastructure construction, and agricultural development. Specific highlights are as follows: 1. Efficient Operation System: Optimizing Power and Precision Powerful and Stable Power Output: Equipped with a Cat C2.4 DI turbocharged engine delivering 36kW of net power and a load-sensing hydraulic system (working pressure of 28,500kPa), it delivers a bucket digging force of 53.2kN and an arm digging force of 36.3kN, easily tackling complex working conditions such as dense soil and gravel. Its turbocharging technology maintains stable power even at high altitudes, preventing performance degradation due to altitude. Leading Cycle Speed: An optimized hydraulic circuit design shortens action response time, resulting in an 8%-12% faster dig-lift-swing cycle than comparable models. This significantly increases load capacity per unit time by over 15% during loading operations. A swing speed of 10.8 rpm and a swing torque of 16.3 kN·m ensure smooth and efficient swing motion. Intelligent Precision Control (optional): Equipped with Cat Grade 2D/3D Grade Control, this system uses onboard sensors and a display to display real-time bucket position and grade deviation. Supporting laser tracking, even novice operators can maintain grade control accuracy within ±2 cm, reducing rework. Combined with the semi-automatic digging assist function, it automatically adjusts the boom and arm angles, reducing operator effort while improving work quality. II. Low Operating Costs: Outstanding Lifecycle Economy Industry-Leading Fuel Efficiency: Featuring an intelligent fuel management system, an automatic idle function that reduces engine speed when not in use, and a load-sensing hydraulic system that distributes fuel only on demand, the machine boasts 10%-15% lower overall fuel consumption than comparable models. Based on an 8-hour operating day, this translates to an average annual fuel cost savings of approximately 20,000 yuan (based on diesel fuel costs of 8 yuan per liter). Highly manageable maintenance costs: The 500-hour engine oil change interval is 20% longer than the industry average, and the replacement cycles for consumable parts like hydraulic oil and coolant have been optimized. The all-steel work panel and centralized maintenance points allow daily checks (such as engine oil and hydraulic oil levels) to be completed in under 15 minutes, reducing maintenance downtime. High residual value and reliability: Key components are from internationally renowned brands. Structural components like the boom and arm have undergone multiple rounds of fatigue testing, and hydraulic lines are coated with a protective layer, extending their service life by over 30% compared to conventional models. Secondhand market data shows that this model’s residual value remains above 60% after three years of use, significantly higher than competing products in its class. 3. Adaptability: Multiple Configurations Cover All Operating Conditions Flexible Chassis and Bucket Options: Available chassis: 450mm steel tracks (optional rubber pads for paved surface protection) or 600mm wide tracks (reducing ground contact pressure to 34.2kPa for soft surfaces). The dozer blade is available in either a standard 2320mm or widened 2470mm configuration. Combined with a standard 0.33m³ bucket capacity and a variety of custom-shaped buckets (such as loosening and crushing buckets), it covers over 10 different operating scenarios, including municipal, mining, and agricultural applications. Strong Auxiliary Hydraulic Scalability: Standard high-pressure auxiliary lines and quick-change connectors allow connection to over 10 types of tools, including breakers and augers, without rewiring. The diverter valve design supports one-way and two-way hydraulic output, reducing tool change time to less than 5 minutes. An optional backup auxiliary oil supply circuit also accommodates rotating tools, such as hydraulic clamps. Excellent adaptability to harsh environments: The entire machine has an IP67 protection rating, the electrical system uses waterproof plugs, and the hydraulic lines are equipped with anti-scratch protective covers. The cooling system adopts a stacked design, which can maintain normal operating temperature even in high-temperature environments such as 45°C. The low center of gravity design with counterweights extending to both sides of the fuselage ensures the entire machine remains stable even when operating on a 35° slope, reducing the risk of rollover by 40%.
