Cat D8T Crawler dozers research

Overview

The 2021 Cat D8T Crawler Dozer, powered by a C15 ACERT engine compliant with EU Stage III standards, has proven to be a reliable workhorse over approximately 7,600 operational hours. Manufactured in Brazil, this dozer boasts a net power of 354 hp (264 kW) and an operating weight of around 87,860 lbs (39,853 kg), making it suitable for heavy-duty applications.

What's new

The 2021 D8T model introduced several updates aimed at boosting productivity and efficiency. Notably, the dozer features up to 18% better dozing efficiency and up to 10% fuel savings, allowing operators to move more material with each liter of fuel. Additionally, the largest Semi-Universal blade in its size class enables up to 13% more material per pass, enhancing overall productivity. ​

The integration of advanced Cat GRADE technology options provides operators with tools to achieve precise grading results, reducing the need for rework and increasing job site efficiency. The cooling system has been upgraded to handle extreme conditions, ensuring optimal performance in both hot and cold environments. These enhancements collectively contribute to a more efficient and user-friendly machine.​

Efficiency and performance

In practical applications, the D8T demonstrates robust performance across various terrains. Its improved dozing efficiency and larger blade capacity allow for effective material handling, reducing cycle times. However, some operators have observed that fuel consumption is higher compared to newer models equipped with advanced fuel-saving technologies. Routine maintenance is straightforward, with easily accessible service points, contributing to reduced downtime and operational costs.​

In-cabin and interior features

The D8T's cab is designed with functionality in mind, offering standard features such as an air-ride suspension seat and adjustable armrests. However, operators have noted that the cab could benefit from ergonomic enhancements, especially during extended shifts. The in-dash display provides real-time machine data, aiding in operational efficiency, but there is room for improvement in terms of user interface and customization options.​

Safety features

Safety remains a priority in the D8T design, with features like enhanced visibility due to large single-pane windows and a tapered hood. The machine is equipped with standard lighting packages that extend the productive workday into low-light conditions. Additionally, the robust build and reliable braking system contribute to a secure operating environment.​

In comparison

When compared to its predecessors and competitors, the 2021 D8T stands out with its improved dozing efficiency and larger blade capacity. However, it falls short in terms of operator comfort and fuel efficiency when compared to newer models that have incorporated advanced ergonomic designs and fuel-saving technologies. Despite these areas for improvement, the D8T's durability and performance make it a competitive choice in the heavy-duty dozer market.​

Verdict

The 2021 Cat D8T Crawler Dozer earns a solid 4-star rating, reflecting its reliability, enhanced productivity features, and robust performance. While there is room for improvement in operator comfort and fuel efficiency, the D8T remains a dependable choice for heavy-duty applications, offering a balance between power and functionality.​
