Key Specifications and Features
Here’s a closer look at some of the core specifications and features of the Caterpillar D11R:
- Engine: The D11R is powered by a high-performance 3412E diesel engine. This engine is known for its durability and fuel efficiency, capable of producing up to 850 horsepower (634 kW), making it ideal for handling the toughest tasks in large-scale operations.
- Weight: The D11R weighs approximately 113,000 pounds (51,300 kg), depending on the configuration and attachments. This substantial weight provides the necessary stability and power to move large volumes of material with ease.
- Blade Capacity: The D11R is equipped with a blade that can carry a significant amount of material. The blade capacity varies depending on the attachment, but it can typically handle between 43 to 47 cubic yards (33 to 36 cubic meters) of material, making it a versatile tool for bulk earthmoving tasks.
- Hydraulic System: The hydraulic system is central to the D11R’s performance. The dozer features a powerful and efficient hydraulic system that allows for precise control over blade movements, increasing operational efficiency and safety.
- Tracks: The D11R is designed with heavy-duty tracks that provide excellent traction in rough terrain. The undercarriage is built to withstand the harshest conditions, ensuring reliability even in demanding environments such as quarries, mines, and construction sites.
- Fuel Efficiency: Despite its massive size, the D11R is engineered for fuel efficiency, helping reduce operating costs in long-term heavy-duty use. This is a significant consideration in industries where fuel costs can be a major component of operating expenses.
The D11R’s performance is nothing short of impressive. With its massive engine and hydraulic power, it is designed to excel in large-scale excavation, mining, and other earthmoving tasks. Here are some of the key performance highlights:
- Earthmoving: The D11R’s massive blade is capable of pushing vast amounts of dirt and debris in a single pass, reducing the number of passes required and thus improving productivity.
- Slope Stability: Thanks to its heavy weight and low center of gravity, the D11R provides excellent stability when working on slopes, making it an ideal machine for grading and surface preparation.
- Precision and Control: Caterpillar’s hydraulic systems, combined with the advanced control mechanisms, allow operators to precisely control the movements of the blade, improving the quality and accuracy of the work.
