Key Features and Specifications of the CAT 345D
The CAT 345D is equipped with advanced technology that sets it apart from its competitors in the same weight class. Below are some of the most significant specifications and features:
- Engine Power: The CAT 345D is powered by a CAT C9 ACERT engine, which produces around 310 horsepower. The engine is known for its high torque and efficient fuel consumption, even in demanding applications.
- Operating Weight: This excavator has an operating weight of approximately 46,000 to 50,000 kg (101,000 to 110,000 lbs), depending on the configuration, making it suitable for heavy lifting and large-scale excavation tasks.
- Hydraulic System: The 345D features a hydraulic system designed for maximum efficiency. The system includes a new electronic control valve that provides more precise and efficient use of hydraulic power, allowing for faster cycle times and reduced fuel consumption.
- Boom and Arm Reach: With a variety of boom and arm configurations, the CAT 345D can be customized to handle different tasks. The standard configurations offer significant reach and digging depth, making it ideal for trenching, material handling, and other heavy excavation tasks.
- Track and Undercarriage: The CAT 345D’s undercarriage is built for stability and durability, designed to withstand harsh jobsite conditions. Its tracks are reinforced for increased wear resistance, and the frame is designed to handle heavy loads without compromising balance or control.
The CAT 345D excels in performance across multiple dimensions, providing operators with a machine capable of handling the most demanding tasks. Whether it’s digging, lifting, or material handling, this excavator delivers high efficiency without sacrificing power.
- Fuel Efficiency: One of the standout features of the CAT 345D is its fuel efficiency. Thanks to the advanced hydraulic and engine systems, the excavator uses less fuel than many comparable models, which helps reduce operational costs in the long term. Caterpillar’s focus on the ACERT technology (Advanced Combustion Emissions Reduction Technology) also contributes to better fuel efficiency by optimizing combustion and lowering exhaust emissions.
- Hydraulic Efficiency: The hydraulic system in the 345D is designed to maximize flow and pressure where needed, reducing power loss and providing more efficient lifting, digging, and other hydraulic functions. The variable displacement pumps and a high-flow hydraulic circuit improve work cycle times, making the 345D faster and more efficient on the job.
- Operator Comfort and Productivity: Caterpillar has placed a strong emphasis on operator comfort in the 345D. The cab is spacious, with ergonomic controls, easy visibility, and advanced air conditioning systems to enhance comfort during long working hours. The improved hydraulic control system also allows for smoother operations, making it easier for operators to perform complex tasks with precision.
In addition to its mechanical and performance attributes, the CAT 345D is equipped with several advanced technological features that improve both productivity and safety:
- CAT Product Link: The 345D can be equipped with CAT Product Link, a telematics system that allows fleet managers to monitor the excavator’s performance, location, fuel consumption, and maintenance status remotely. This system helps to improve fleet management, reduce downtime, and optimize equipment utilization.
