The excavator's compact design and powerful hydraulics make it an ideal choice for both urban and rural projects, particularly in tight spaces where maneuverability is essential.
Key Features and Specifications of the CAT 312BL
- Engine: The CAT 312BL is powered by a Caterpillar 3054T diesel engine, which offers a balance of power and fuel efficiency. It provides approximately 110 horsepower, making it suitable for heavy lifting, digging, and trenching operations. The engine's high torque allows the excavator to perform efficiently even in challenging ground conditions.
- Hydraulic System: One of the standout features of the 312BL is its hydraulic system, which is designed to offer smooth and powerful operations. The hydraulic flow rate is optimized for a variety of attachments, making it highly versatile for digging, lifting, and material handling. The system also ensures excellent fuel efficiency and reduced operating costs.
- Operating Weight: The 312BL weighs approximately 12,000 to 13,000 kg (26,455 to 28,660 lbs) depending on configuration, making it a mid-sized excavator ideal for urban and medium-scale construction sites. This operating weight ensures both stability and the ability to handle heavy loads.
- Digging Depth and Reach: The 312BL has a maximum digging depth of around 6.2 meters (20.3 feet), with a maximum reach of approximately 9.7 meters (31.8 feet). These specifications make it effective for deep excavation and long-reach tasks, such as ditching and trenching.
- Boom and Arm Configuration: The 312BL features an optimized boom and arm configuration that allows for greater digging force and faster cycle times. The boom is reinforced for enhanced durability, and the arm can be customized to different lengths depending on the specific requirements of the job.
The CAT 312BL is known for its solid performance in various operating conditions. Whether working in soft soil, rock, or in construction debris, the machine provides efficient and precise control. It has several performance features that increase its productivity and efficiency:
- Hydraulic Efficiency: The excavator’s hydraulics are fine-tuned to provide consistent pressure and flow, allowing for better cycle times and reduced fuel consumption. This feature helps save costs in both fuel and maintenance.
- Fuel Economy: While large excavators often consume large amounts of fuel, the 312BL stands out for its ability to offer a good balance of power and fuel efficiency. This is particularly beneficial for contractors looking to reduce operating expenses in the long term.
- Operator Comfort: The cabin of the CAT 312BL is ergonomically designed to reduce operator fatigue and improve overall productivity. With easy-to-use controls, air-conditioning, and a good range of visibility, the operator’s comfort is a top priority. The controls are intuitive, and the machine provides a smooth, stable experience even in demanding environments.
CAT machines, including the 312BL, are built with durability and easy maintenance in mind. This makes them reliable for long-term use in tough conditions.
